[0022] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0023] To this end, the present invention proposes a method, device, system, electronic equipment and storage medium for intelligent battery heating of a pure electric vehicle.

[0024] Specifically, an intelligent battery heating method, device, system, electronic device, and storage medium for a pure electric vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] Figure 1This is a flow chart of an intelligent battery heating method for a pure electric vehicle according to one embodiment of the present invention. It should be noted that the intelligent battery heating method for a pure electric vehicle according to this embodiment of the present invention can be applied to an intelligent battery heating device for a pure electric vehicle according to this embodiment of the present invention. This device can be configured on an electronic device or a server. The electronic device can be a PC or a mobile terminal. This is not limited in this embodiment of the present invention.

[0026] like Figure 1 As shown, the intelligent battery heating method of a pure electric vehicle includes:

[0027] S110, receiving a heating signal and determining whether a battery heating condition is met.

[0028] In an embodiment of the present invention, the heating signal may be received by a terminal device, for example, by triggering a switch button of the terminal device to receive the heating signal.

[0029] In one embodiment of the present invention, the heating signal may also be received via voice. For example, when a voice message "start heating" is received, the heating signal may be received.

[0030] In an embodiment of the present invention, the battery heating condition is satisfied when the current second battery temperature is lower than a preset temperature threshold, there are no thermal management-related faults, and the vehicle's cruising range is greater than the first range from the current location to the destination, and the vehicle's cruising range is greater than a preset range threshold. The second temperature value can be understood as the current battery temperature.

[0031] S120 : When it is determined that the battery heating condition is met, a first temperature value that achieves optimal performance of the current battery parameters and a second temperature value of the current battery are obtained.

[0032] In one embodiment of the present invention, when it is determined that the battery heating conditions are met, it is determined that the battery heating function is successfully turned on, and information that the battery heating function is successfully turned on is provided to the user; when it is determined that the battery heating conditions are not met, it is determined that the battery heating function fails to be turned on, and information that the battery heating function fails to be turned on is provided to the user.

[0033] Among them, a sign indicating that the heating function is successfully turned on or a sign indicating that the heating function fails to be turned on can be displayed on the vehicle instrument.

[0034] The information that the battery heating conditions are met may be provided to the user through voice announcement, or the reason why the battery heating conditions are not met may be provided to the user.

[0035] For example, the first temperature value that achieves the optimal performance of the current battery parameters can be understood as a predicted temperature value, for example, a factory-set temperature value.

[0036] S130 , automatically heating the current battery using an advance heating method according to the first temperature value and the second temperature value.

[0037] In an embodiment of the present invention, the heating time of the first battery is determined based on the first temperature value and the second temperature value; the sum of the heating time of the first battery and the preset heating time is used as the advance heating time, and the current battery is automatically heated based on the advance heating time.

[0038] The first battery heating time can be determined by the correspondence between the temperature value and the heating time. For example, based on a correspondence table, the first temperature value and the second temperature value are input, and the first battery heating time can be output.

[0039] For example, the first temperature value for the optimal performance of the current battery parameters is 30 degrees Celsius. Based on the preset time for heating the current battery temperature to 30 degrees Celsius, a request to turn on heating is made a certain time in advance. For example, if the current battery temperature is -10 degrees Celsius and it takes 30 minutes to heat to 30 degrees Celsius, and navigation to the destination requires 10 minutes in advance, the sum of the 30 minutes required to navigate to the destination and the 10 minutes of advance heating time is used as the advance heating time. That is, when the destination is 40 minutes away, the heating request function is turned on. This method of automatically heating the vehicle battery in advance avoids slow charging of the vehicle battery due to poor battery performance due to low ambient temperature.

[0040] In one embodiment of the present invention, after the current battery is automatically heated, if it is determined that the current battery temperature reaches a first temperature value, the current battery temperature is maintained; if it is determined that the current battery temperature does not reach the first temperature value, the current battery is automatically heated again.

[0041] For example, when the front battery automatically heats to 30 degrees Celsius, it maintains the current battery temperature based on the preset insulation time. If the current battery temperature drops to 27 degrees Celsius, the heating request function is activated again. This pre-heating and appropriate insulation method saves power by not keeping the current battery at 30 degrees Celsius for a long time.

[0042] It should be noted that when the current battery is automatically heated, the water heater PTC is controlled to heat at high power and the water pump starts to run at high speed. When it is determined that the on-board battery BMS is in the insulation state, the water heater PTC is controlled to heat at low power and the water pump starts to run at low speed.

[0043] S140: When it is determined that the automatic heating exit condition is met, exiting the automatic heating is executed.

[0044] In an embodiment of the present invention, it is determined that the automatic heating exit conditions are met, including one or more of the following: plugging in the gun to start charging, the current cruising range is insufficient to reach the charging station, turning off the navigation or switching the destination, actively turning off the battery automatic heating function, the on-board battery BMS reporting a thermal management fault, the water heater PTC reporting a fault, the air conditioner reporting a fault, and the cabin domain control CDCS reporting a fault.

[0045] According to an embodiment of the present invention, the intelligent battery heating method for a pure electric vehicle receives a heating signal and determines whether battery heating conditions are met. When the battery heating conditions are determined to be met, a first temperature value and a second temperature value of the current battery are obtained to achieve optimal performance of the current battery parameters. Based on the first and second temperature values, the current battery is automatically heated using a pre-heating method. When the automatic heating exit conditions are determined to be met, the automatic heating is exited. This method enables pre-heating of the vehicle battery, avoiding slow charging of the vehicle battery due to poor battery performance caused by low ambient temperature.

[0046] In order to make it easier for people skilled in the art to understand the present invention, the present invention also proposes an intelligent battery heating system for a pure electric vehicle.

[0047] like Figure 2 As shown, the intelligent battery heating system 200 of the pure electric vehicle includes a vehicle controller VCU 210, an onboard battery BMS 220, a cabin domain controller CDCS 230, a communication module TBOX 240, an air conditioner CLM 250, a water heater PTC 260 and a water pump 270.

[0048] The cockpit domain controller CDCS 230 may send a heating signal to the vehicle controller VCU 210 via the communication module TBOX 240 .

[0049] Among them, the cockpit domain controller CDCS 230 can also send information on whether the navigation map has started navigation, whether the navigation destination is a charging station or a service area with charging piles, and the time required to navigate to the destination to the vehicle controller VCU210 through the communication module TBOX 240.

[0050] The vehicle-mounted battery BMS 220 may send the current battery temperature signal and power level signal to the vehicle controller VCU 210 in real time.

[0051] In an embodiment of the present invention, the vehicle controller VCU 210 receives a heating signal and can determine whether the battery heating conditions are met. When it is determined that the battery heating conditions are met, the first temperature value that achieves the optimal performance of the current battery parameters and the second temperature value of the current battery are obtained, and then the first battery heating time is determined based on the first temperature value and the second temperature value. The sum of the first battery heating time and the preset heating time is used as the advance heating time, and based on the advance heating time, the current on-board battery BMS220 is automatically heated, and the on-board battery BMS 220 sends a heating signal to the air conditioner CLM 250. When the air conditioner CLM250 receives the signal from the on-board battery BMS 220, the vehicle controller VCU210 controls the water heater PTC 260 to start heating at high power and the water pump 270 starts to run at high speed.

[0052] After the current battery is automatically heated, when the current battery temperature reaches a first temperature value within a period of time, the current battery temperature is maintained, and the water heater PTC is controlled to heat at low power and the water pump starts to run at a low speed.

[0053] Corresponding to the intelligent battery heating methods for pure electric vehicles provided in the above-mentioned embodiments, an embodiment of the present invention also provides an intelligent battery heating device for a pure electric vehicle. Since the intelligent battery heating device for a pure electric vehicle provided in the embodiment of the present invention corresponds to the intelligent battery heating methods for pure electric vehicles provided in the above-mentioned embodiments, the implementation method of the intelligent battery heating method for a pure electric vehicle is also applicable to the intelligent battery heating device for a pure electric vehicle provided in this embodiment, and will not be described in detail in this embodiment.

[0058] The exit module 340 is configured to exit the automatic heating function when it is determined that the automatic heating exit condition is met.

[0059] According to an embodiment of the present invention, the intelligent battery heating device for a pure electric vehicle receives a heating signal and determines whether the battery heating conditions are met. When the conditions are determined to be met, the device obtains a first temperature value that achieves optimal performance of the current battery parameters and a second temperature value of the current battery. Based on the first and second temperature values, the device automatically heats the current battery using a pre-heating method. When the automatic heating exit conditions are determined to be met, the device exits the automatic heating process. This enables pre-heating of the vehicle battery and avoids slow charging of the vehicle battery due to poor battery performance caused by low ambient temperature.

[0060] In one embodiment of the present invention, the battery heating conditions are satisfied including the second temperature value of the current battery being lower than a preset temperature threshold, there being no thermal management related faults, and the vehicle cruising range being greater than the first mileage from the current location to the destination and the vehicle cruising range being greater than a preset mileage threshold.

[0061] In one embodiment of the present invention, the acquisition module 320 is specifically used to determine that the battery heating function is successfully turned on when it is determined that the battery heating condition is met, and provide the user with information that the battery heating function is successfully turned on; when it is determined that the battery heating condition is not met, determine that the battery heating function fails to be turned on, and provide the user with information that the battery heating function fails to be turned on.

[0062] In one embodiment of the present invention, the heating module 330 is specifically used to determine the heating time of the first battery based on the first temperature value and the second temperature value; take the sum of the first battery heating time and the preset heating time as the advance heating time, and automatically heat the current battery based on the advance heating time.

[0063] In one embodiment of the present invention, the heating module 330 is specifically used to automatically heat the current battery, and when it is determined that the current battery temperature reaches the first temperature value, maintain the current battery temperature; when it is determined that the current battery temperature does not reach the first temperature value, automatically heat the current battery again.

[0064] In one embodiment of the present invention, the automatic heating exit conditions are met, including one or more of: plugging in the charger to start charging, the current cruising range is insufficient to reach the charging station, turning off navigation or switching the destination, actively turning off the battery automatic heating function, the on-board battery BMS reporting a thermal management fault, the water heater PTC reporting a fault, the air conditioner reporting a fault, and the cabin domain control CDCS reporting a fault.
