Detailed Description

Reference will now be made in detail to the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar parts or parts having the same or similar functions throughout. In addition, if a detailed description of the known art is not necessary for illustrating the features of the present application, it is omitted. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

It will be understood by those within the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It is to be understood that the term "and/or" as used herein is intended to include all or any and all combinations of one or more of the associated listed items.

The key components of the electric vehicle driven by the battery are not only the battery, but also a management system of the battery, and since the prior art cannot provide the single battery with the whole power demand of the whole vehicle, the battery on the electric vehicle is usually a battery pack composed of a large number of single batteries, for example, a battery pack composed of 18650 batteries, or a battery pack composed of polymer batteries, etc. In order to achieve proper operation of the battery pack, it is necessary to rely on a management system capable of managing the individual cells in the battery pack. The management system needs to ensure normal energy input and output of the battery and ensure safe operation of the battery.

At the end of user demand, for example, for a vehicle driven by a battery, the actual working condition is not stable, a low-lying place and a steep slope exist on the road, and the vehicle also has a rapid acceleration on a flat ground during driving. Therefore, how to balance between high power output and heat influence and solve the problem of power consumption demand of users is the key work of the battery control system.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.

An embodiment of the first aspect of the present application provides a control method of a battery, as shown in fig. 1, including the following steps:

s100: and acquiring the required power, and if the required power exceeds the rated output power of the battery, determining the peak discharge power closest to the required power as the output power according to a preset peak discharge power table.

S200: and determining the actual output electric energy of the battery and the peak output electric energy of the battery according to the running time and the output power of the battery and a preset peak discharge power meter.

S300: and if the actual output electric energy is larger than or equal to the peak output electric energy, adjusting the output power to the rated output power of the battery.

With the above battery control method, the electric device, such as an electric vehicle or an electric engineering machine, receives a power demand command from a user, and usually inputs the power demand command through a button or a pedal. The battery management system of the electric equipment acquires the required power and firstly judges whether the required power exceeds the rated output power of the battery. If the output power is not exceeded, namely the required power is equal to the rated output power or less than the rated output power, the battery management system directly outputs the power according to the rated output power of the battery. If the required power is larger than the rated output power, in order to guarantee the requirement of a user, under the condition that the battery can provide the peak power larger than the rated output power, the peak power output is preferentially adopted.

By adopting the peak power output, the battery is inevitably enabled to work under a large load in a short time, the electric energy output by the battery exceeds the electric energy which can be output under the working state of the peak power of the battery, and in order to avoid the condition of damaging the battery, the battery management system does not preferentially ensure the required power any more, but adopts the rated output power of the battery to output energy outwards.

According to the control method of the battery provided by the embodiment of the application, the preset peak discharge power meter which represents the characteristics of the battery is fully utilized, the peak discharge power which is closest to the required power is firstly used as the output power, the sudden high-power requirement of a user is met, then the safety of the battery is ensured by evaluating the actual output power and the peak output power of the battery, and the rated output power of the battery is used for outputting the actual output power to the outside. The control method of the battery can fully excavate the performance of the battery, so that the electric equipment can cope with various high-power requirement working conditions, and the operation safety of the battery can be ensured.

For S100, after receiving the required power data sent by the user, the battery management system first needs to compare the required power data with the rated output power of the battery, and determines whether to search for the closest peak discharge power according to the comparison result. The rated power of the battery and the preset peak discharge power meter of the battery are determined according to the characteristics of the battery, and the battery performance is known from the factory. The peak discharge power of the battery is larger than the rated power of the battery, the peak discharge power is obtained by a standard discharge test method in a laboratory by a common manufacturer, and the batteries in the same batch, even the batteries in the same production process have the same preset peak discharge power meter.

Typically, the battery is capable of operating at peak power for a period of time, which can be short or long depending on the performance of the battery. In addition, the same battery or battery pack may be operated at different peak powers for different periods of time, such as 40 seconds at a first peak power, 50 seconds at a second peak power, and so on. Through the test of a manufacturer, a preset peak discharge power table including different peak powers of the battery and the operation time corresponding to the peak powers can be obtained. Also, during charging, there is a preset peak charging power meter. Details of the related technology can be known to those skilled in the art and are not described in detail.

And when the required power input by the user is greater than the rated output power of the battery, searching on a preset peak discharge power table according to the value of the required power, finding the peak discharge power closest to the required power as a power response, and outputting the power response. It should be noted that the peak discharge power closest to the required power is not necessarily the maximum peak discharge power on the preset peak discharge power table, and therefore, there is a problem concerning the output start position of the output power, and provision is made for determining whether the battery output power needs to be changed at a later stage.

Optionally, in a specific implementation manner of the embodiment of the present application, the preset peak discharge power table in S100 includes a plurality of peak powers arranged in a descending order; the step of determining a peak discharge power closest to the required power as the output power includes:

respectively subtracting each peak power in a preset peak discharge power meter by using the required power to obtain a plurality of first power difference values;

and if at least one first power difference value is smaller than or equal to zero, determining the peak discharge power corresponding to the maximum first power difference value as the output power.

According to the process in S100, the battery operates at the peak discharge power closest to the required power, and for convenience of description, the peak discharge power is P in the preset peak discharge power table defined in the present application_iWork corresponding to peak discharge powerAs a time t_iWherein i is a positive integer, and the value ranges are different according to different performances of the battery, for example, a preset peak discharge power table of a certain battery is as shown in table 1:

TABLE 1

Serial number	Peak discharge power	Peak operating time
			1	P1	t1
2	P2	t2
			…	…	…
i	Pi	ti

The peak power closest to the required power can be found by the difference method, and for the sake of better understanding of the method, the method is described by way of mathematical operation. Defining the required power as Pr, and obtaining a first power difference value according to a preset peak discharge power meter: Δ Pi is Pr-Pi;

when Δ P_i0 or less, and Δ P_i-1＞0，ΔP_i+1＜ΔP_iSelecting the maximum Δ P_iCorresponding P_iAs output power, responding to the user's demand power P_r. More specifically, when the maximum first power difference is Δ P₃Then, the peak power P is adopted₃Externally output, maintain peak power P₃The time of the external output is t₃。

In another possible embodiment, the step of determining the peak discharge power closest to the required power as the output power in S100 further includes:

respectively subtracting each peak power in a preset peak discharge power meter by using the required power to obtain a plurality of first power difference values;

and if the first power difference values are all larger than zero, determining the maximum peak discharge power as the output power.

The mathematical sign and formula described above are used to determine the total first power difference Δ P_iAre all larger than zero, i.e. the required power exceeds the maximum peak power P of the preset peak discharge power meter₁Then the power requirement of the user cannot be completely met, and only partial meeting is selected, and the maximum peak power P is used₁As an output power output. The realization mode can output energy to the outside by the maximum capacity of the battery under the condition that the power required by a user is overlarge, and simultaneously, the safety of the battery is ensured.

Optionally, there is a specific implementation manner in the foregoing embodiment, where the preset peak discharge power table includes a plurality of peak powers arranged in a descending order of the battery power, and the step of determining, in S100, a peak discharge power closest to the required power as the output power includes:

determining the peak discharge power P closest to the required power_iAnd the preset peak discharge power meter is smaller than the peak discharge power P closest to the required power_iFirst peak power P of_i+1；

Will P_iPeak discharge power and P closest to the required power_i+1Preset peak discharge power meter lower thanThe average value of the first peak power of the peak discharge power is used as the output power.

Since the power output of the battery is linear over a certain continuous period of time, no power transition will generally occur, for example, an instantaneous and steep drop from 10kW to 8kW, but will gradually change with a certain drop unless the battery fails or has special performance parameters. In order to avoid power jump of the external output power of the battery, the peak power is given by adopting an average value processing mode.

As shown in fig. 2, curve S₂Is the lapse of time t₁Curve S of₁Curve S in the figure₁And curve S₂The horizontal lines between the two are respectively the peak power in the preset peak discharge power meter. When elected to take out P_iAs the peak discharge power closest to the required power, for example, P is specified₂Then P is selected₃P is the next closest peak discharge power₂And P₃Is taken as the specific output power value, i.e. the midpoint of the vertical line segment in fig. 2, at the pentagon. Through the processing, the power output of the battery is smoother, the battery is further protected, and the long service life of the battery is ensured.

At S200, the battery has been actually operated for a period of time, and it is determined whether it is necessary to change the actual output power of the battery according to the operation condition. In a specific implementation of the above embodiment, the operation time of the battery includes a peak operation time and a non-peak operation time, and the peak operation time is a time when the battery operates at a peak discharge power closest to the required power; the preset peak discharge power meter comprises a plurality of peak powers which are arranged in a descending order and working time intervals corresponding to the peak powers; the step of determining the actual output power of the battery and the peak output power of the battery in S200 includes:

and determining the actual output electric energy of the battery according to the output power of the battery and the running time of the battery.

And determining the peak output electric energy of the battery according to a preset peak discharge power meter and the peak operation time.

The actual running time and the output power of the battery can determine the actual output electric energy of the battery, and during specific calculation, the integral of the output power and the time of the battery is obtained, so that the electric energy actually emitted by the battery is obtained. According to a preset peak discharge power meter of the battery and a time starting point for starting certain peak discharge power, the peak output electric energy of the battery can be calculated, specificallySince the peak powers in the preset peak discharge power meter are arranged in descending power order, i.e. P₁>P₂>…>P_MaxPossible initial output power is P₂Then the slave output power P₂And starting to calculate the corresponding peak value running time until the electric energy released by all the peak value power is calculated, so as to obtain the peak value output electric energy of the battery. And if the actual output electric energy of the battery exceeds the peak output electric energy of the battery, the danger of overdischarge of the battery is indicated, and the working mode needs to be switched in time to ensure the safety of the battery.

Optionally, in a specific implementation manner of the embodiment of the first aspect of the present application, after the step of adjusting the output power to the rated output power of the battery if the actual output power is greater than or equal to the peak output power in S300, the method further includes:

acquiring the actual temperature of the battery;

and when the actual temperature is lower than the rated temperature of the battery, updating the rated output power of the battery and a preset peak discharge power meter.

When the battery is in a stage of working at peak power, the battery continues to work at rated output power or below the rated output power, and the heat dissipation performance of the battery is greater than the heat generation performance of the battery, so that the actual temperature of the battery is lower than the rated temperature of the battery, the safety of the battery does not need to be considered preferentially at the moment, and the battery can enter a new round of high-power output. The battery management system can re-evaluate the current parameters of the battery according to the electric energy stored by the battery and the electric energy consumed in the previous stage, and update the rated output power of the battery and the preset peak discharge power meter. The specific evaluation or updating methods, known to those skilled in the relevant art, are not problems to be solved by the present application and will not be described further.
