The following detailed description is made with reference to the specific drawings and examples.

Example one

Referring to fig. 1 and fig. 2, the method for detecting leakage provided by the embodiment of the present invention is mainly used for detecting the leakage inside the battery pack case 20, so as to achieve the functions of detecting and warning the leakage inside the battery pack case 20. The liquid leakage detection system 10 detects and warns the liquid leakage condition inside the battery pack box 20 by adopting the liquid leakage detection method; it should be noted that the liquid leakage detection system 10 mainly includes a humidity detector 11, a microprocessor 12 and an alarm device 13, and the microprocessor 12 is used for executing the following steps of the liquid leakage detection method.

The leakage detection method comprises the following steps:

s10, acquiring a real-time humidity value inside the battery pack box body 20;

it should be noted that the moisture content inside the battery pack case 20 is obtained by obtaining the real-time humidity value inside the battery pack case 20.

Optionally, microprocessor 12 is built-in or external to moisture detector 11; arranging the humidity detector 11 in the battery pack box 20 manually or by a mechanical arm, wherein the humidity detector 11 is arranged in the battery pack box 20 and acquires humidity data in the battery pack box 20; the microprocessor 12, which may be internal or external, calculates the humidity data obtained by the humidity detector 11 to obtain a real-time humidity value inside the battery pack case 20 after calculation, so as to obtain a water content condition inside the battery pack case 20. Wherein, the humidity detector 11 is arranged in the battery pack case 20 and can contact the moisture in the battery pack case 20; the sensing material of the moisture detector 11 changes after contacting with the moisture inside the battery pack case 20, the changed data refers to the above-mentioned moisture data, and generally, the changed data has a certain functional relationship with the real-time moisture value, and the microprocessor 12 calculates the moisture data to obtain the real-time moisture value, that is, the real-time moisture value inside the battery pack case 20 is obtained, so as to obtain the moisture content inside the battery pack case 20.

S20, judging whether the real-time humidity value exceeds a preset humidity interval or not;

it should be noted that the preset humidity interval is a boundary line of whether the moisture inside the battery pack case 20 exceeds the standard, that is, whether a liquid leakage phenomenon occurs inside the battery pack case 20; the preset humidity interval may be set according to the actual performance of the power battery pack, and is not limited herein.

Optionally, whether the real-time humidity value exceeds a preset humidity interval is judged, and the method specifically comprises the following steps: the microprocessor 12 compares and judges the calculated real-time humidity value with a preset humidity interval to obtain a conclusion whether the real-time humidity value exceeds the preset humidity interval, so as to obtain a conclusion whether the liquid leakage phenomenon occurs in the battery pack box 20.

And S31, when the real-time humidity value exceeds the preset humidity interval, acquiring signals for starting the picture alarm and the voice alarm so as to start the picture alarm and the voice alarm at the same time.

And S32, when the real-time humidity value does not exceed the preset humidity interval, acquiring signals for closing the picture alarm and the voice alarm so as to close the picture alarm and the voice alarm at the same time.

It should be noted that, when the real-time humidity value exceeds the preset humidity interval, it is indicated that the real-time humidity value inside the battery pack box 20 is not within the preset humidity interval, the moisture inside the battery pack box 20 exceeds the standard, and a liquid leakage phenomenon has occurred inside the battery pack box 20, and it can be understood that at this time, the power battery pack needs to prepare a repair measure or needs to perform a repair work in time; by simultaneously starting the picture alarm and the voice alarm, namely simultaneously sending out alarm information in the form of the picture alarm and the voice alarm, the driver obtains the alarm information that the liquid leakage phenomenon occurs in the battery pack box body 20.

It should be further noted that when the real-time humidity value does not exceed the preset humidity interval, that is, the real-time humidity value is within the preset humidity interval, at this time, the moisture inside the battery pack box 20 does not exceed the standard, and the liquid leakage phenomenon does not occur inside the battery pack box 20, so that it can be understood that the power battery pack is in a normal working state; by turning off the picture alarm and the voice alarm at the same time, the driver can normally use the power battery pack, and the situation that the prompting words and the prompting device 132 work to cause the driver to be panic is avoided.

Optionally, the image alarm and the voice alarm are implemented by the alarm device 13, wherein the alarm device 13 includes a display device 131 and a prompt device 132, and both the display device 131 and the prompt device 132 are electrically connected to the microprocessor 12; the display device 131 is used for alarming on the screen, and the prompting device 132 is used for alarming on the voice. It can be understood that, when the real-time humidity value exceeds the preset humidity interval, the microprocessor 12 controls the display device 131 to alarm in a picture mode, and simultaneously controls the prompting device 132 to alarm in a voice mode; when the real-time humidity value does not exceed the preset humidity range, the microprocessor 12 controls the display device 131 to turn off the frame alarm, and simultaneously controls the prompting device 132 to turn off the voice alarm.

Optionally, the image alarm specifically includes a prompt word displayed by the display device 131, and it can be understood that the display device 131 displays a prompt word for prompting the driver that a liquid leakage phenomenon occurs inside the battery pack case 20, that is, the display device 131 prompts the driver in the form of the prompt word; the voice alarm specifically includes a prompt sound sent by the prompting device 132, and it can be understood that the prompting device 132 sends a prompt sound for prompting the driver that the inside of the battery pack case 20 has the liquid leakage phenomenon, that is, the prompting device 132 prompts the driver in the form of the prompt sound. Therefore, when the real-time humidity value exceeds the preset humidity interval, it indicates that a liquid leakage phenomenon occurs inside the battery pack box 20, and the display device 131 and the prompting device 132 respectively prompt the driver of alarm information that a liquid leakage phenomenon occurs inside the battery pack box 20 through two different dimensions of vision and hearing; here, the alarm information includes a prompt word displayed on the display device 131 and a prompt sound generated by the prompt device 132. Therefore, on one hand, the liquid leakage phenomenon can be fed back to the driver more accurately and timely, correspondingly, the driver can more accurately and timely acquire alarm information of the liquid leakage phenomenon, the problem that the power battery pack cannot be repaired in time due to the fact that the driver does not notice the alarm information is avoided, and timeliness of repairing the power battery pack is improved; on the other hand, the display device 131 and the prompting device 132 provide the driver with two times of alarm information, when the function of any one of the picture alarm function of the display device 131 and the voice alarm function of the prompting device 132 is damaged, the other device can also continue to provide the alarm information, so that the leakage detection system 10 can timely send out the alarm information when the leakage occurs in the battery pack box 20, and the feedback accuracy of the alarm information is ensured.

In the embodiment of the invention, by adopting the technical scheme, the judgment of the water content condition in the battery pack box body 20 is realized by acquiring the real-time humidity value in the battery pack box body 20 and judging whether the real-time humidity value exceeds the preset interval, so as to acquire a signal whether liquid leakage occurs in the battery pack box body 20; when the real-time humidity value in the battery pack box 20 exceeds the preset humidity interval, the real-time humidity value indicates that the water content in the battery pack box 20 exceeds the standard and the liquid leakage phenomenon occurs in the battery pack box 20, and at the moment, signals for starting a picture alarm and a voice alarm are obtained, thereby simultaneously starting the picture alarm and the voice alarm, so that a driver can respectively obtain the alarm information of the leakage phenomenon in the battery pack box body 20 through two dimensions of vision and hearing, so that the driver can more timely and accurately acquire the leakage situation inside the battery pack box 20, therefore, corresponding repairing measures are taken in time to prevent moisture in the battery pack box body 20 from being accumulated continuously, the problem that the power battery pack output power is low due to the fact that the insulation performance of the circuit in the battery pack box body 20 is reduced is solved, and safety accidents that the power battery pack is burnt and ignited due to the fact that the circuit in the battery pack box body 20 is short-circuited are prevented.

In one embodiment, referring to fig. 1 and 2, in step S31, when the real-time humidity value exceeds the preset humidity range, the method for acquiring the signals for turning on the frame alarm and the voice alarm to turn on the frame alarm and the voice alarm at the same time includes the following steps:

It should be noted that the second preset threshold is greater than the first preset threshold, the highest endpoint value of the preset humidity interval is equal to or less than the first preset threshold, and the highest endpoint value of the preset humidity interval is less than the second preset threshold; when the real-time humidity value is larger than a first preset threshold value, the real-time humidity value is beyond a preset humidity interval; when the real-time humidity value is greater than the first preset threshold and less than the second preset threshold, it indicates that the real-time humidity value inside the battery pack box 20 exceeds the preset humidity range and is less than the second preset threshold, that is, the real-time humidity value inside the battery pack box 20 is within the controllable range, and it can be understood that the liquid leakage phenomenon occurs inside the battery pack box 20, but is not very serious and is within the controllable range.

It should be further noted that the prompt typeface includes a first prompt typeface; the first prompting typeface is displayed at the first preset frequency, and the display device 131 can be used for prompting the first prompting typeface in a flashing mode at the first preset frequency, so that the observability and the warning performance of the first prompting typeface are improved. The prompt tone comprises a first prompt tone; the first prompt sound is emitted at the second preset frequency, and it can be understood that the prompt device 132 emits the first prompt sound at the second preset frequency, so that the warning performance of the first prompt sound is improved.

Thus, by adopting the technical scheme, when the real-time humidity value is greater than the first preset threshold and less than the second preset threshold, the first prompt character is displayed at the first preset frequency, and the first prompt sound is sent at the second preset frequency, so that the warning performance of the first prompt character and the first prompt sound is improved, namely, the warning performance of the warning information in two dimensions of vision and hearing is improved, a driver can timely and accurately acquire the liquid leakage condition inside the battery pack box body 20, the situation that the driver leaks the warning information is avoided, and the driver can prepare corresponding repair measures more timely, so that the corresponding repair work can be performed when the liquid leakage condition inside the subsequent battery pack box body 20 is more serious; the alarm information described herein is a first prompt typeface and a first prompt tone.

Optionally, in this embodiment, the first preset frequency is the same as the second preset frequency, so that the first prompt typeface displayed by the display device 131 and the first prompt tone sent by the prompt device 132 work synchronously, the synchronism and coordination of the work of the display device 131 and the prompt device 132 are improved, the alarm information sent by the display device 131 and the prompt device 132 can be more completely and clearly fed back to the driver, the probability of misjudgment of the conclusion whether the liquid leakage phenomenon occurs in the battery pack box 20 by the driver is reduced, and the repair work of the power battery pack is ensured. The first preset frequency and the second preset frequency are respectively 1 time/second, and of course, according to actual requirements, the first preset frequency and the second preset frequency may also be set to other frequency values, even the first preset frequency and the second preset frequency may also be set to be different, and no unique limitation is performed here.

Optionally, in this embodiment, the first prompt word is "battery pack leakage", so that the driver can clearly obtain the information that the battery pack box 20 has the leakage phenomenon, and certainly, according to actual needs, the first prompt word may also be set to be another prompt word, which is not limited herein.

In one embodiment, referring to fig. 1 and fig. 2, after the step of displaying the first prompt word at the first preset frequency and simultaneously emitting the first prompt sound at the second preset frequency in step S31, the method further includes the following steps:

obtaining a signal for closing the first prompt word after a first preset time, so as to close the first prompt word after the first preset time; obtaining a signal for closing the first prompt tone after a second preset time, and closing the first prompt tone after the second preset time; the first preset time and the second preset time are the same or different.

It should be noted that, a signal for turning off the first prompt typeface after the first preset time is obtained, so as to turn off the first prompt typeface after the first preset time, it can be understood that the display device 131 flashes the first prompt typeface at a first preset frequency, and automatically turns off after the first preset time, so as to automatically stop the alarm operation, that is, the first prompt typeface only flashes for the first preset time, and then automatically stops the alarm operation; the signal of closing the first warning sound after the second preset time is obtained, so as to close the first warning sound after the second preset time, it can be understood that the prompting device 132 sends the first warning sound at the second preset frequency, and automatically closes after the second preset time, so as to automatically stop the alarm operation, that is, the first warning sound only works for the second preset time, and then automatically stops the alarm operation. In this way, when the real-time humidity value is greater than the first preset threshold and less than the second preset threshold, the display device 131 and the prompting device 132 both send out alarm information only for a period of time, and then automatically stop the alarm operation.

In step S31, when the real-time humidity value is greater than the first preset threshold and smaller than the second preset threshold, it indicates that a liquid leakage phenomenon occurs inside the battery pack case 20, but the liquid leakage phenomenon is not very serious and is within a controllable range, and at this time, based on the severity of the liquid leakage problem inside the battery pack case 20, the power battery pack does not need to be immediately repaired. Thus, the display device 131 is turned off after the first preset time to stop flashing the first prompt typeface; the prompting device 132 is turned off after a second preset time to stop sending the first prompting sound; it can be understood that the display device 131 sends out alarm information to prompt the driver for the first preset time, and the prompt device 132 sends out alarm information to prompt the driver for the second preset time, so that the driver has time to prepare corresponding repair measures in advance, and then timely repair the battery pack box 20 when the liquid leakage phenomenon is more serious.

Therefore, by adopting the technical scheme, when the real-time humidity value inside the battery pack box body 20 is larger than the first preset threshold and smaller than the second preset threshold, the driver can acquire alarm information for a period of time through two dimensionalities of vision and hearing respectively, so that corresponding repair measures can be prepared in advance, repair work of the inside of the follow-up battery pack box body 20 when the liquid leakage phenomenon is more serious can be better dealt with, and thus, performance protection of the power battery pack is improved.

Optionally, first preset time is the same with second preset time, and thus, the working time that display device 131 flickers first prompt typeface is the same with the working time that prompt device 132 sends first prompt sound with second preset frequency, and it can be understood that first prompt typeface and first prompt sound are sent simultaneously, and alarm operation is closed simultaneously, so that the synchronism and harmony of first prompt typeface and first prompt sound are improved, and it is helpful for a driver to more clearly and accurately obtain the liquid leakage condition inside battery pack box 20, and thereby it is helpful for the follow-up smooth repair work of the power battery pack. The first preset time and the second preset time are 10 seconds, and of course, according to actual requirements, the first preset time and the second preset time may also be set to other time values, even, the first preset time and the second preset time may also be set to be different, where the first preset time and the second preset time are not uniquely limited.

In one embodiment, referring to fig. 1 and 2, in step S31, when the real-time humidity value exceeds the preset humidity range, the method obtains a signal for turning on the frame alarm and the voice alarm to turn on the frame alarm and the voice alarm at the same time, and specifically includes the following steps:

when the real-time humidity value is larger than a second preset threshold value, acquiring signals for starting a picture alarm and a voice alarm, displaying a second prompt character at a third preset frequency, and simultaneously sending out a second prompt sound at a fourth preset frequency; wherein the third preset frequency is the same as or different from the fourth preset frequency; the third preset frequency is greater than the first preset frequency and the second preset frequency, and the fourth preset frequency is greater than the first preset frequency and the second preset frequency.

It should be noted that, when the real-time humidity value is greater than the second preset threshold, it indicates that the real-time humidity value inside the battery pack case 20 is greater than the second preset threshold at this time, a liquid leakage phenomenon occurs inside the battery pack case 20, and the liquid leakage phenomenon is very serious; it can be understood that, at this moment, the power battery pack should be stopped from being used, and corresponding repair measures are taken in time to repair the power battery pack.

The prompt typeface also comprises a second prompt typeface; the second prompt typeface is flickered at the third preset frequency, and it can be understood that the display device 131 prompts the second prompt typeface in a form of flickering at the third preset frequency, so that the observability and the warning performance of the second prompt typeface are improved. The prompt tones further comprise a second prompt tone; the second warning sound is emitted at the fourth preset frequency, and it can be understood that the warning device 132 emits the second warning sound at the fourth preset frequency, so that the warning performance of the second warning sound is improved. So, display device 131 with the second suggestion typeface of third frequency scintillation that predetermines, and suggestion device 132 sends the second prompt tone with the fourth frequency of predetermineeing simultaneously, the warning performance of second suggestion typeface and second prompt tone has been improved, that is to say, the warning performance of alarm information in vision and two dimensions of sense of hearing has been improved, make the driver in time, accurately acquire the inside serious weeping circumstances of battery package box 20, avoid the driver to leak this alarm information, thereby make the driver can carry out corresponding repair work to the power battery package more in time.

It should be further noted that, if the third preset frequency is greater than the first preset frequency and the second preset frequency, the flashing frequency of the second prompt typeface is greater than the flashing frequency of the first prompt typeface and the prompt frequency of the first prompt tone, and the flashing frequency of the second prompt typeface is higher and more urgent, so that the driver can distinguish the urgency degree of the second prompt typeface from the first prompt typeface and the first prompt tone; the fourth preset frequency is greater than the first preset frequency and the second preset frequency, the prompt frequency of the second prompt tone is greater than the prompt frequency of the first prompt tone and the flicker frequency of the first prompt character, the prompt frequency of the second prompt tone is higher and more urgent, and the driver can be helped to distinguish the emergency degree of the second prompt tone different from the first prompt tone and the first prompt character. Therefore, when the real-time humidity value is greater than the second preset threshold value, the display device 131 flickers the second prompt word, the prompt device 132 sends out the second prompt sound, and the flicker frequency of the second prompt word is higher than the flicker frequency of the first prompt word and the prompt frequency of the first prompt sound, the frequency of the second prompt sound is higher than the prompt frequency of the first prompt sound and the flicker frequency of the first prompt word, based on the frequency of the second prompt word and the second prompt sound, the driver can clearly know that the inside of the battery pack box body 20 at the moment is in the serious liquid leakage phenomenon, and the driver can be helped to repair the power battery pack in time.

Therefore, by adopting the technical scheme, on one hand, a driver can timely and accurately acquire the serious liquid leakage condition inside the battery pack box body 20, and the condition that the driver leaks the alarm information is avoided. On the other hand, the flicker frequency of the second prompt word is higher than the flicker frequency of the first prompt word and the frequency of the prompt tone, and the frequency of the second prompt tone is higher than the frequency of the first prompt tone and the frequency of the first prompt word, so that the division of the severity of the leakage condition inside the battery pack box body 20 is realized, and the division of the emergency degree of the repair work of the power battery pack is correspondingly realized; when the real-time humidity value is greater than the first preset threshold and less than the second preset threshold, a liquid leakage phenomenon occurs but is not serious inside the battery pack box 20, and at the moment, corresponding repair measures can be prepared in advance so as to facilitate corresponding repair work when a serious liquid leakage phenomenon occurs inside the subsequent battery pack box 20; when the real-time humidity value is greater than the second preset threshold value, serious weeping phenomenon appears in the inside of battery package box 20, this moment is more urgent to the repair work of power battery package, based on the repair measure who prepares in advance before, can be very timely, carry out repair work to the power battery package fast, avoid the power battery package to take place the short circuit, serious phenomena such as catching fire, like this, the method that this embodiment provided can strictly be held and carry out repair work's type and opportunity to the power battery package, specifically do: when to prepare the repair measures, and when to repair the power battery pack based on the prepared repair measures; therefore, the phenomenon that the driver performs repair work to cause resource waste when liquid leakage occurs in the battery pack box body 20 at the beginning is well avoided, and meanwhile, the phenomenon that the driver does not perform repair work on the power battery pack in time to cause safety accidents such as power battery pack burning and firing when serious liquid leakage occurs in the battery pack box body 20 is also avoided.

Optionally, the third preset frequency is the same as the fourth preset frequency, so that the second prompt word flickered by the display device 131 and the second prompt tone sent by the prompt device 132 work synchronously, the synchronism and coordination of the display device 131 and the prompt device 132 are improved, the alarm information sent by the display device 131 and the prompt device 132 can be more completely and clearly fed back to the driver, the probability that the driver misjudges the conclusion whether the liquid leakage phenomenon occurs in the battery pack box 20 is reduced, and the repair work of the power battery pack is ensured; here, the alarm information refers to a second prompt typeface and a second prompt tone. The third preset frequency and the fourth preset frequency are respectively 1 time/0.5 second, and of course, according to actual requirements, the second preset frequency and the third preset frequency may also be set to other frequency values, even the third preset frequency and the fourth preset frequency may also be set to be different, and the frequency values of the third preset frequency and the fourth preset frequency are not limited uniquely here.

Optionally, in this embodiment, the second prompt style is "serious leakage of the battery pack", so that the driver can clearly obtain the information that the battery pack box 20 has serious leakage, and certainly, according to actual needs, the second prompt style may be set to be other prompt styles, and even the second prompt style may be set to be the same as the first prompt style, where the first prompt style and the second prompt style are not uniquely defined.

Optionally, the frequencies of the second warning tone and the first warning tone are different, however, the contents of the second warning tone and the first warning tone may be set to be the same or different.

In one embodiment, referring to fig. 1 and fig. 2, after the step of displaying the second prompt word at the third preset frequency and simultaneously emitting the second prompt sound at the fourth preset frequency in step S31, the method further includes the following steps:

acquiring a signal for continuously displaying the second prompt word sample, and continuously displaying the second prompt word sample at a third preset frequency; and acquiring a signal for continuously emitting the second prompt tone, and continuously emitting the second prompt tone at a fourth preset frequency.

It should be noted that, the second prompt typeface is continuously displayed at the third preset frequency, and it can be understood that the display device 131 always flickers the second prompt typeface, and if no manual operation is performed, the second prompt typeface does not automatically stop flickering; and the second prompt tone is continuously sent out at the fourth preset frequency, and as can be understood, the prompt device 132 always sends out the second prompt tone, and if the second prompt tone is not manually controlled, the prompt device does not automatically stop prompting the alarm. Thus, when the real-time humidity value is greater than the second preset threshold, the display device 131 and the prompting device 132 continue to alarm.

In step S31, when the real-time humidity value inside the battery pack case 20 is greater than the second preset threshold, it indicates that a serious leakage phenomenon occurs inside the battery pack case 20, and at this time, the power battery pack needs to be repaired in time; therefore, when the real-time humidity value is larger than the second preset threshold value, the display device 131 continuously flickers the second prompt character, and the prompt device 132 continuously sends out the second prompt sound at the same time, so that the phenomenon that the interior of the battery pack box body 20 is seriously leaked at the moment is shown to a driver, and the repair work needs to be carried out in time. When the power battery pack is repaired manually, the display device 131 and the prompting device 132 can be manually turned off manually; alternatively, the power battery pack may be turned off at this time, and the display device 131 and the prompting device 132 may be turned off along with the turning off of the power battery pack, or the turning off of the alarm operation of the display device 131 and the prompting device 132 may be another operation mode.

Through adopting above-mentioned technical scheme, when the inside real-time humidity value of battery package box 20 is greater than the preset threshold value of second, the driver can continuously obtain the alarm information of second suggestion typeface and second prompt tone, with the information that the inside of battery package box 20 was in serious weeping this moment of acquireing, that is, the driver can know the severity of the inside weeping condition of battery package box 20 this moment, thus, the driver can carry out corresponding repair work to the power battery package in time, avoid the inside moisture of battery package box 20 constantly to accumulate and lead to the internal circuit of power battery package to take place the short circuit and arouse the incident that the burning was on fire, thereby the security performance of power battery package has been improved.

In one embodiment, referring to fig. 1 and 2, in step S31, when the real-time humidity value exceeds the preset humidity range, the method for starting the image alarm and the voice alarm is further performed, and the method further includes the following steps:

acquiring real-time humidity value information and displaying a first real-time humidity value;

in step S32, when the real-time humidity value does not exceed the preset humidity range, the method obtains a signal for turning off the frame alarm and the voice alarm, and further includes the following steps while turning off the frame alarm and the voice alarm at the same time:

and acquiring the real-time humidity value information and displaying a second real-time humidity value.

It should be noted that, when the real-time humidity value exceeds the preset humidity interval, the first real-time humidity value is displayed; and when the real-time humidity value does not exceed the preset humidity interval, displaying a second real-time humidity value. Like this, through adopting above-mentioned technical scheme for the driver can obtain the inside water content condition of battery package box 20 through first real-time humidity value and the real-time humidity value of second, thereby realizes detection, the early warning function to the weeping condition of battery package box 20 inside.

Optionally, acquiring real-time humidity value information, and displaying the first real-time humidity value; it can be understood that, when the real-time humidity value exceeds the preset humidity interval, the microprocessor 12 obtains the real-time humidity value inside the battery pack case 20 at this time, and feeds back the real-time humidity value to the display device 131, and the display device 131 displays the real-time humidity value, which is the first real-time humidity value at this time. Acquiring real-time humidity value information and displaying a second real-time humidity value; it can be understood that, when the real-time humidity value does not exceed the preset humidity interval, the microprocessor 12 obtains the real-time humidity value inside the battery pack case 20 at this time, and feeds back the real-time humidity value to the display device 131, and the display device 131 displays the real-time humidity value, which is the second real-time humidity value at this time. Like this, the driver can obtain the inside real-time humidity value of battery package box 20 in real time through display device 131 to acquire the inside water content condition of battery package box 20, thereby make preliminary judgement to the inside weeping condition of battery package box 20, with realize detecting, the early warning function, improved the protection effect to the power battery package.

Optionally, the real-time humidity value may include a humidity percentage and a water content, and the microprocessor 12 calculates humidity data obtained by the humidity detector 11 to obtain the humidity percentage and the water content inside the battery pack box 20; microprocessor 12 all feeds back to display device 131 with the inside humidity percentage and the water content of battery package box 20 for display device 131 shows the inside humidity percentage and the water content of battery package box 20 simultaneously, makes and makes the driver can acquire the inside humidity percentage and the water content of battery package box 20 more directly perceivedly, and can judge in advance whether the inside weeping problem appears of battery package box 20 through two dimensions of humidity percentage and water content respectively, has improved the performance protection to power battery package.

In one embodiment, referring to fig. 1 and 2, in step S31, the step of displaying the first real-time humidity value includes: displaying the first real-time humidity value in a first color; in step S32, the step of displaying the second real-time humidity value specifically includes: displaying the second real-time humidity value in a second color; wherein the second color is different from the first color.

It should be noted that, the first real-time humidity value is displayed in a first color, and it is understood that the display device 131 displays the first real-time humidity value in the first color; the second real-time humidity value is displayed in a second color, and it can be understood that the display device 131 displays the second real-time humidity value in the second color.

The preset humidity interval is a boundary line for determining whether or not liquid leakage occurs inside the battery pack case 20. It can be understood that when the real-time humidity value inside the battery pack case 20 exceeds the preset humidity range, a liquid leakage phenomenon occurs inside the battery pack case 20, and at this time, the display device 131 displays the first real-time humidity value inside the battery pack case 20 in a first color; when the real-time humidity value inside the battery pack box 20 is within the preset humidity interval, no leakage phenomenon occurs inside the battery pack box 20, correspondingly, the power battery pack is in a normal use state, and at the moment, the display device 131 displays the second real-time humidity value inside the battery pack box 20 in a second color. Thus, under the condition that the liquid leakage phenomenon does not occur in the battery pack box 20 and the liquid leakage phenomenon occurs in two different situations, the display device 131 displays the real-time humidity value in the battery pack box 20 in two different colors, so that the driver can know whether the liquid leakage phenomenon occurs in the battery pack box 20 based on the real-time humidity value information of the different colors on the display device 131, and further, the real-time humidity value information of the different colors also provides the alarm information for the driver, when the picture alarm function of the display device 131 and the voice alarm function of the prompt device 132 are damaged, the display device 131 can also provide the alarm information for the driver through the real-time humidity value information of the different colors, so that the driver can also obtain the information whether the liquid leakage phenomenon occurs in the battery pack box 20 through the real-time humidity value information of the different colors, the leakage detection system 10 is ensured to send out alarm information when the leakage phenomenon occurs in the battery pack box 20, and the feedback accuracy of the alarm information is ensured.

Optionally, based on the general subjective understanding of people, in the embodiment, the first color is set to red, the second color is set to green, and red generally has the subjective meaning of emergency and prohibition of use, so that when the display device 131 displays the first real-time humidity value in red, the driver can easily know the leakage phenomenon inside the battery pack case 20 by the first reaction. Of course, the first color and the second color may be set to other colors as long as the first color and the second color are clearly distinguished.

In an embodiment, referring to fig. 1 and fig. 2, in step S31, the step of simultaneously turning on the screen alarm and the voice alarm includes: and carrying out picture alarm in the first color and simultaneously carrying out voice alarm.

It should be noted that, the image alarm is performed by using the first color, and it can be understood that, in step 31, when the real-time humidity value exceeds the preset humidity range, the display device 131 displays the prompt word by using the first color to implement the image alarm.

It should be noted that the first color is the color of the first real-time humidity value displayed by the display device 131 when the real-time humidity value inside the battery pack case 20 exceeds the preset humidity range, the appearance of the first color indicates that a liquid leakage phenomenon occurs inside the battery pack case 20, and thus, the prompt words displayed by the display device 131 are also set to the first color, when the real-time humidity value inside the battery pack box 20 exceeds the preset humidity range, the real-time humidity value displayed by the display device 131 and the displayed prompt word are both in the first color, so that the uniformity of the color at the moment is realized, thus, the observability of the alarm information that the display device 131 prompts the driver of the occurrence of the liquid leakage phenomenon inside the battery pack case 20 can be improved, the driver can be helped to more clearly and accurately acquire the alarm information, so as to help the driver to make adaptive repair measures based on the liquid leakage phenomenon inside the battery pack box body 20 in time.

Based on the concept of the above-mentioned leakage detection method, illustratively, under the condition that the temperature is 25 ℃, the air drying value is 25% RH, the light humid air is 25% RH-70% RH, and the heavy humid air is more than 70% RH; it can be understood that the preset humidity range is 0-25% RH, the first preset threshold is 25% RH, and the second preset threshold is 70% RH. When the real-time humidity value inside the battery pack box body 20 is within a preset humidity interval, namely less than 25% RH, it is indicated that no liquid leakage phenomenon occurs inside the battery pack box body 20 at this time, and the power battery pack is in a normal use state; when the real-time humidity value inside the battery pack box body 20 is greater than the first preset threshold and less than the second preset threshold, that is, within the humidity range of 25% RH to 70% RH, a liquid leakage phenomenon occurs inside the battery pack box body 20, but is not serious and is within a controllable range at this time; when the real-time humidity value inside the battery pack case 20 is greater than the second preset threshold, that is, greater than 70% RH, a phenomenon of serious leakage occurs inside the battery pack case 20 at this time.

The leakage detection system 10 includes a moisture detector 11, a microprocessor 12, and an alarm device 13. The humidity detector 11 is arranged in the battery pack box 20 to obtain humidity data inside the battery pack box 20; the alarm device 13 is electrically connected with the microprocessor 12 to carry out picture alarm and voice alarm; the microprocessor 12 is electrically connected to the humidity detector 11 to obtain a real-time humidity value inside the battery pack box 20 through the humidity data; the microprocessor 12 is configured to turn on the alarm device 13 when the real-time humidity value exceeds the preset humidity range, and turn off the alarm device 13 when the real-time humidity value does not exceed the preset humidity range. The alarm device 13 comprises a display device 131 and a prompt device 132, wherein the display device 131 is electrically connected to the microprocessor 12 and is used for displaying a prompt word when the real-time humidity value exceeds a preset humidity range so as to realize image alarm; the prompting device 132 is electrically connected to the microprocessor 12 and is configured to send a prompting sound when the real-time humidity value exceeds the preset humidity range, so as to implement a voice alarm.

The microprocessor 12 is electrically connected to the humidity detector 11, the display device 131, and the prompting device 132, respectively. When the liquid leakage detection is carried out, the humidity detector 11 is arranged inside the battery pack box body 20, the humidity detector 11 acquires humidity data inside the battery pack box body 20, and the microprocessor 12 calculates the humidity data of the humidity detector 11 to acquire a real-time humidity value inside the battery pack box body 20 and judges the real-time humidity value to judge whether the real-time humidity value exceeds a preset humidity interval; when the microprocessor 12 judges that the real-time humidity value inside the battery pack box body 20 exceeds the preset humidity interval, the microprocessor 12 controls the display device 131 to display a prompt word to realize the picture alarm work; and the microprocessor 12 controls the prompting device 132 to send out a prompting sound at the same time so as to realize the voice alarm work. Thus, the microprocessor 12 realizes the opening of the picture alarm and the voice alarm, so that the driver can obtain the alarm information of the liquid leakage phenomenon in the battery pack box body 20 through the prompt words and the prompt voice, the driver can be helped to prepare repair measures in time and carry out corresponding repair work in time based on the liquid leakage phenomenon, the occurrence of safety accidents such as combustion, fire and the like caused by the short circuit of the internal circuit of the power battery pack is avoided, and the protection of the power battery pack and the driver is improved. Correspondingly, when the microprocessor 12 judges that the real-time humidity value inside the battery pack box 20 does not exceed the preset humidity interval, the microprocessor 12 controls the display device 131 to close the prompt word so as to close the image alarm work; and the microprocessor 12 simultaneously controls the prompting device 132 to turn off the prompting sound to turn off the voice alarm, thus realizing the turning off of the picture alarm and the voice alarm.

Wherein, the moisture detector 11 is arranged on the inner wall of the bottom of the battery pack case 20 at the side where the liquid cooling plate is arranged.

Optionally, the display device 131 of the liquid leakage detection system 10 is further configured to display a real-time humidity value; it can be understood that, when the microprocessor 12 determines that the real-time humidity value inside the battery pack box 20 exceeds the preset humidity interval, the microprocessor 12 feeds the real-time humidity value back to the display device 131, so that the display device 131 displays the first real-time humidity value; when the microprocessor 12 determines that the real-time humidity value inside the battery pack box 20 does not exceed the preset humidity range, the microprocessor 12 feeds the real-time humidity value back to the display device 131, so that the display device 131 displays a second real-time humidity value. In this way, the display device 131 displays the real-time humidity value inside the battery pack case 20 in real time under the control of the microprocessor 12, and the driver can acquire the humidity inside the battery pack case 20 in real time to acquire the water content inside the battery pack case 20. The display device 131 for displaying the real-time humidity value and the display device 131 for displaying the prompt word in the above embodiments may be the same display device or different display devices.

Therefore, by adopting the above technical scheme, when the real-time humidity value inside the battery pack box 20 exceeds the preset humidity interval, the microprocessor 12 can control the display device 131 and the prompting device 132 to remind the driver that the liquid leakage phenomenon occurs inside the battery pack box 20 through two dimensionalities of vision and hearing respectively, so that the driver can more timely and accurately acquire the liquid leakage condition inside the battery pack box 20, and accordingly, corresponding repairing measures are timely taken to prevent the moisture inside the battery pack box 20 from being continuously accumulated, the problem that the insulation performance of the circuit inside the battery pack box 20 is reduced to drive the output power of the power battery pack to be low is relieved, and the safety accidents that the power battery pack is burnt and ignited and the like due to the short circuit of the circuit inside the battery pack box 20 are prevented. Accordingly, when the real-time humidity value inside the battery pack box 20 does not exceed the preset humidity range, the microprocessor 12 can control the display device 131 and the prompting device 132 to be turned off, so as to ensure the normal operation of the power battery pack.

Optionally, the microprocessor 12 is electrically connected to the humidity detector 11 through a first cable 14, and the display device 131 and the prompting device 132 are both electrically connected to the microprocessor 12 through a second cable 15; as can be appreciated, in operation, the moisture detector 11 acquires moisture data inside the battery pack case 20 and converts the moisture data into an electrical signal; the microprocessor 12 collects the electric signal output by the moisture detector 11 in real time through the first cable 14 and processes the electric signal, so as to obtain a real-time humidity value in the battery pack box 20; the microprocessor 12 transmits the real-time humidity value inside the battery pack box 20 to the display device 131 through the second cable 15 in real time, and the display device 131 displays the real-time humidity value inside the battery pack box 20 in real time; the microprocessor 12 also processes the real-time humidity value to determine whether the real-time humidity value inside the battery pack box 20 exceeds a preset humidity range; when the real-time humidity value inside the battery pack case 20 exceeds the preset humidity interval, the microprocessor 12 sends a signal to the display device 131, so that the display device 131 displays a prompt word, and the microprocessor 12 sends a signal to the prompt device 132, so that the prompt device 132 sends a prompt sound.

Optionally, referring to fig. 2 and 4, the humidity detector 11 includes a housing 111, a water absorption member 112, and a humidity sensor 113. The housing 111 is disposed in the battery pack case 20, and preferably, the housing 111 is disposed on an inner wall of a side of the bottom of the battery pack case 20 where the liquid cooling plate is disposed, which helps the water absorbing member 112 to more efficiently and accurately absorb water in the battery pack case 20. A plurality of water absorption holes 1111 are formed in the shell 111 and distributed at intervals, and the water absorption piece 112 is accommodated in the shell 111, so that the water absorption piece 112 can absorb water in the battery pack box body 20 through the water absorption holes 1111 in the shell 111; the water absorbing member 112 may be formed of quicklime, a water absorbent cotton pad, or the like, which can absorb water. The humidity sensor 113 penetrates the housing 111 and is inserted into the water absorbing member 112; in this way, when the water absorbing member 112 absorbs the water inside the battery pack case 20, the water contacts the humidity sensor 113, so that the humidity sensor 113 acquires the humidity data on the water absorbing member 112 to indirectly acquire the humidity data inside the battery pack case 20. Wherein the first cable 14 is connected between the humidity sensor 113 and the microprocessor 12.
