The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.

As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

As described in the background art, the electric power assisting technology in the prior art has a problem of battery power shortage, and the inventor finds that the problem is caused by lack of equipment for monitoring the electric quantity when a storage battery is used as an electric energy source, and the cost of the whole vehicle is increased if an external detection device is used.

For the reasons mentioned above, the present invention provides a solution for cost and power control,

in one embodiment, as shown in fig. 1, there is provided a battery level control method including the steps of:

s110, acquiring the voltage of the battery module;

wherein the battery module is a module for providing electric energy arbitrarily, such as a battery module,

specifically, the voltage of the battery module may be acquired by any means in the art. The voltage of the battery module is acquired, for example, using a voltage detection device. In addition, the voltage of the battery module may vary due to factors such as deterioration, difference in ambient temperature, and variation in load during use. Therefore, the voltage of the battery module cannot completely reflect the battery capacity, and the problem of low reliability exists when the battery capacity is detected by using a voltage acquisition device which is a low-cost device.

S120, controlling the motor to be switched to a motor state and controlling the battery module to supply power to the motor under the condition that the voltage is greater than a first set value and the current electric power assisting condition is met;

the electric power assisting condition can be any condition in the field that needs electric energy to provide power. For example: the vehicle may be accelerated rapidly or started. The parameters may be specifically: the throttle opening change rate exceeds a set value, or the engine speed is within a set range.

Specifically, the motor may be an ISG (Integrated Starter and Generator), and may be controlled to switch to a motor state or a Generator state.

When the voltage is larger than a first set value and the current electric power assisting condition is met, the battery module supplies power to the motor, and the motor in the motor state drives the engine crankshaft to rotate so as to provide power for the vehicle to advance. The first setting value can be set according to the specific situation of the battery module.

S130, acquiring the accumulated time length of the battery module in the power supply state in the current control period, and controlling the motor to be switched to the generator state under the condition that the accumulated time length is greater than or equal to the set time so as to charge the battery module by the motor.

The control period may be set according to actual needs, for example, one control period may be between 60s and 300 s. The set time may be set according to the capacity of the battery module, and for example, the set time may be 30 s. In the current control period, when the accumulated time length of the battery module in the power supply state, namely the total time length of the battery module for supplying power is greater than the set time, the motor is controlled to be switched to the engine state, and therefore the battery module is charged. Further, the time length of the battery module charged by the motor can be the sum of the remaining time of the current control period and the time of the next control period.

According to the battery electric quantity control method, under the condition that the current electric power assisting condition is met and the voltage of the battery module is greater than the first set value, the battery module supplies power to the motor. And then, acquiring the accumulated power supply time of the battery module in the current control period, and controlling the motor to charge when the accumulated power supply time is greater than a set value. By setting the power supply condition and the charging condition, the battery module can be applied to the electric power-assisted vehicle without power shortage. Simultaneously, because this application only need monitor the voltage of battery module, compare in the cost that the electric quantity monitored the product.

specifically, the accelerator opening change rate may be obtained by any means in the art, for example, the accelerator opening may be detected by using the opening sensor, and the change rate at the current time may be calculated. Engine speed may be obtained by any means known in the art.

And S220, if the throttle opening change rate is larger than a preset value and/or the engine rotating speed falls into a preset range, determining that the current electric power assisting condition is met.

It should be noted that, when the throttle opening change rate is greater than the preset value, it indicates that the current acceleration is rapid, and it is determined that the current electric power assisting condition is satisfied. And when the rotating speed of the engine falls into a preset range, confirming that the electric power assisting condition is currently met. Further, when the change rate of the opening degree of the throttle valve is larger than a preset value and the rotating speed of the engine falls into a preset range, the current electric power assisting condition is determined to be met.

In one embodiment, as shown in fig. 3, there is provided a battery level control method, including the steps of:

s310, acquiring the voltage of the battery module;

s320, controlling the motor to be switched to a motor state and controlling the battery module to supply power to the motor under the condition that the voltage is greater than a first set value and the current electric power assisting condition is met;

s330, acquiring the accumulated time length of the battery module in the power supply state in the current control period, and controlling the motor to be switched to the generator state under the condition that the accumulated time length is greater than or equal to the set time so as to charge the battery module by the motor.

Further comprising the steps of:

and S340, if the battery module is in a power supply state and the voltage of the battery module is less than a second set value, controlling the battery module to stop supplying power to the outside.

Specifically, if the voltage of the battery module is smaller than the second set value in the power supply process, the battery module is controlled to stop supplying power to the outside so as to avoid power shortage. Furthermore, after the battery module is controlled to stop supplying power to the outside, the motor can be controlled to be switched to a motor state, and the battery module is controlled to supply power to the motor. The time length of charging the battery module by the motor can be the sum of the remaining time of the current control period and the time of the next control period.

According to the battery electric quantity control method, when the voltage is smaller than the second set value, the battery module is switched from the power supply state to the charging state, so that the electric quantity of the battery module is maintained within the required range.

In one embodiment, as shown in fig. 4, there is provided a battery level control method, including the steps of:

Further comprising the steps of:

and S440, entering the next control period and clearing the accumulated time under the condition that the accumulated time is less than the set time.

Specifically, in the next control period, the accumulated time length of the battery module in the power supply state in the next control period is obtained, and the motor is controlled to be switched to the generator state under the condition that the accumulated time length is greater than or equal to the set time, so that the motor charges the battery module. And if the battery module is in a power supply state and the voltage of the battery module is less than a second set value, controlling the battery module to stop supplying power to the outside.

s530, acquiring the accumulated time length of the battery module in the power supply state in the current control period, and controlling the motor to be switched to the generator state under the condition that the accumulated time length is greater than or equal to the set time, so that the motor charges the battery module.

Further comprising the steps of:

and S540, if the duration that the battery module is in the power supply state is detected to be greater than a third set value, controlling the battery module to stop supplying power to the outside.

Specifically, the duration of the power supply state of the battery module cannot be greater than a third set value, for example, the third set value is 3s, that is, the single power supply driving of the battery module cannot exceed 3s, and if the single power supply driving of the battery module exceeds 3s, the battery module is controlled to stop supplying power to the outside so as to quit the electric power assistance. Further, under the condition that the next voltage is larger than the first set value and the current electric power assisting condition is met, the battery module continues to supply power to the outside for electric power assisting.
