In the related art, the triggering condition for determining whether the vehicle enters the battery heating mode is mostly to control the vehicle to enter the battery heating mode through the current temperature of the power battery, namely, to control the vehicle to enter the battery heating mode in the case that the current temperature is less than the preset low-temperature threshold value, and to control the vehicle to exit the battery heating mode in the case that the current temperature is greater than or equal to the preset high-temperature threshold value, so that whether the battery is heated is determined only through the current battery temperature, regardless of the driving condition of the vehicle and the current remaining power of the vehicle, not only the condition for controlling the vehicle to enter the battery heating mode is single, but also the battery heating function is started frequently in the short-distance driving process (for example, moving the vehicle from one position to another position within a short distance), and the battery heating function is started in the short-distance driving process at the end of the vehicle stroke, the temperature of the battery still keeps the original shape, namely under the condition that the heating does not produce the effect, the heating is stopped, so that the output power and the output current of the battery are not favorably influenced, the electric quantity consumption is increased, the energy consumption of the whole vehicle is not favorably reduced, the endurance mileage is not favorably improved, and the vehicle cost is not favorably reduced.
In order to solve the technical problem, the present disclosure provides a method, an apparatus and a vehicle for controlling heating of a battery, wherein the method includes acquiring current driving information of the vehicle; acquiring the residual electric quantity of a power battery in the vehicle under the condition that the running information meets the preset battery heating condition; and controlling the vehicle to enter a battery heating mode under the condition that the residual capacity is greater than or equal to a preset capacity threshold. Therefore, whether the vehicle is controlled to enter a battery heating mode or not is determined through the running information of the vehicle and the current residual capacity of the power battery, the problem that the battery heating mode is started when the residual capacity of the power battery is low can be effectively avoided, the endurance of the vehicle is not promoted, the running information of the vehicle can be increased under the condition that the battery heating mode is started in control, the problem that the control condition for starting the battery heating mode is single can be effectively avoided, the energy consumption of the whole vehicle can be reduced under the condition that the normal work of the vehicle is guaranteed, and the endurance mileage of the vehicle is promoted.

It should be noted that, under the condition that the driving information satisfies the preset battery heating condition, the current non-short-distance driving state of the vehicle can be represented, so that when the current vehicle is in the non-short-distance driving state, whether the vehicle is controlled to enter the battery heating mode is determined according to the current residual electric quantity of the vehicle, the driving information of the vehicle can be combined to avoid the phenomenon that the vehicle enters the battery heating mode in the short-distance running process, so that the heating time is short, under the condition that the heating effect is not reflected, the vehicle stops, and the electric quantity waste phenomenon is caused, thereby being beneficial to reducing the energy consumption of the whole vehicle, promoting the driving mileage and reducing the vehicle cost.
And 103, controlling the vehicle to enter a battery heating mode under the condition that the residual capacity is greater than or equal to a preset capacity threshold.
In this step, in the battery heating mode, the current temperature of the power battery can be acquired; and adjusting the temperature of the power battery according to the current temperature and a preset temperature threshold value.

It should be noted that, when it is determined that the remaining power is less than the preset power threshold, it indicates that the remaining power of the current power battery is low, and if only the remaining power is used for heating the battery, the long-time cruising demand of the vehicle is affected, so that in order to ensure the basic cruising demand of the vehicle, the battery heating mode is not started when it is determined that the remaining power is less than the preset power threshold; and under the condition that the residual capacity is determined to be greater than or equal to the preset capacity threshold, the current residual capacity of the vehicle can meet the power consumption requirement for heating the battery on the basis of meeting the long-time cruising requirement, so that under the condition that the residual capacity is determined to be greater than or equal to the preset capacity threshold, the vehicle can be controlled to enter a battery heating mode.
According to the technical scheme, whether the vehicle is controlled to enter the battery heating mode or not is determined through the running information of the vehicle and the current residual capacity of the power battery, the problem that the battery heating mode is started when the residual capacity of the power battery is low can be effectively avoided, the endurance of the vehicle is not promoted, the running information of the vehicle can be increased under the condition that the battery heating mode is started in control, the problem that the control condition for starting the battery heating mode is single can be effectively avoided, the energy consumption of the whole vehicle can be reduced under the condition that the normal work of the vehicle is guaranteed, and the endurance mileage of the vehicle is promoted.

For example, if the preset mileage threshold is 20KM, the preset time period is 30 seconds, the first preset speed threshold is 80KM/H, and when the driving mileage of a certain city operating vehicle from the time of last leaving the whole vehicle sleep state to the current time is 20KM, it is determined that the preset battery heating condition is satisfied; or determining that the preset battery heating condition is met when the running speeds of the urban operation vehicles within 30 seconds are all determined to be greater than 80 KM/H.
In this step, step 203 is executed if it is determined that the running information satisfies the preset battery heating condition, and step 201 is executed if it is determined that the running information does not satisfy the preset battery heating condition.

The preset heating strategies corresponding to different heating levels may be different heating temperatures, for example, the higher the heating level is, the higher the temperature output by the heating device implementing heating in the corresponding preset heating strategy is, the faster the heating speed is.
For example, the preset temperature threshold may be 40 ℃, and when the current temperature is less than or equal to 40 ℃, determining a heating level corresponding to the current temperature, and adjusting the temperature of the power battery according to a preset heating strategy corresponding to the heating level; the heating level is as shown in fig. 3 (fig. 3 is a schematic diagram of heating levels shown in an exemplary embodiment of the disclosure), when the current temperature of the power battery is-30 ℃ to-10 ℃, the highest heating level L5 corresponds to the preset heating strategy corresponding to the heating level L5, which may be heating at 65 ℃, when the current temperature of the power battery is-10 ℃ to 10 ℃, the heating level L4 corresponds to the preset heating strategy corresponding to the heating level L4, which may be heating at 60 ℃, when the current temperature of the power battery is 10 ℃ to 20 ℃, the heating level L3 corresponds to the preset heating strategy corresponding to the heating level L3, which may be heating at 55 ℃, when the current temperature of the power battery is 20 ℃ to 30 ℃, the heating level L2 corresponds to the preset heating level L2, which may be heating at 50 ℃, when the current temperature of the power battery is 30 ℃ to 40 ℃, corresponding to the heating level L1, the preset heating strategy corresponding to the heating level L1 may be heating at a temperature of 40 ℃, and in a case that the current temperature of the power battery is greater than 40 ℃, the heating of the power battery is stopped. It should be noted that the heating temperature corresponding to each heating level is only used for illustration and is not used to limit the specific protection scope.
Like this, through step 201 to step 205, whether control the vehicle and get into the battery heating mode according to the travel information and the residual capacity of vehicle are confirmed, not only can combine the travel information of vehicle to avoid the vehicle at the short distance operation in-process, get into the battery heating mode, thereby can prevent that the heating time is shorter, under the condition that the heating effect has not embodied yet, finish the heating, the extravagant phenomenon of electric quantity that causes, can also avoid when the residual capacity of power battery is lower, open the battery heating mode, be unfavorable for promoting the problem of the duration of vehicle, thereby can effectively reduce whole car energy consumption, promote the duration mileage, reduce the cost of using the car, promote vehicle user experience.
