Description

Technical Field

[0001] The present disclosure relates to the field of energy control of new energy vehicles, and in particular to a thermal management control method, device, storage medium, and electronic equipment for new energy vehicles. Background Art

[0002] For example, the thermal management system of a range-extended pure electric vehicle connects each powertrain through piping and uses a cooling medium to exchange heat between each powertrain and the external environment, keeping each powertrain operating within its optimal temperature range. The vehicle controller collects the temperatures of each powertrain and controls the thermal management system's water pump and fan, achieving heat exchange and achieving thermal equilibrium among the assemblies.

[0003] Current thermal management strategies rely on current data to manage the powertrain's thermal performance. For example, the vehicle controller (VCU) uses the powertrain's current temperature to determine whether to cool or heat the powertrain. However, this results in delayed thermal management, causing unexpected temperature fluctuations and an inability to accurately control the powertrain's temperature within a specified range. This reduces powertrain efficiency and increases power loss, increasing energy loss, shortening driving range, and reducing powertrain life. Summary of the Invention

[0049] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0050] The first embodiment of the present disclosure provides a thermal management control method for a new energy vehicle, wherein the new energy vehicle is, for example, a hybrid electric vehicle, and in particular, a range-extended pure electric vehicle. In this embodiment, the thermal management control method is applicable to the thermal management of the power system of a vehicle such as the range-extended pure electric vehicle. Specifically, adjusting the control strategy by predicting the vehicle's driving conditions, charging conditions, and road conditions is a key factor in achieving thermal management of the power system. The disclosed embodiment can better control the temperature of each powertrain, improve the efficiency of each powertrain, and thus increase the vehicle's range.

[0051] like Figure 1 As shown, in one embodiment, the extended-range pure electric vehicle includes a drive motor 11, a power battery 14, an engine 15, and a generator 16, wherein the drive motor 11 and the generator 16 serve as the main powertrain system. Of course, the vehicle also includes a vehicle controller and a navigation system, wherein the navigation system can provide the vehicle controller with driving information, such as the mileage to the destination, the road conditions on the future driving route, the location and type of charging piles on the future driving route, the distance between each charging pile and the current location, the ambient temperature, and other information.

[0052] In the process of thermal management of the powertrain including the drive motor 11, the generator 16, etc., a thermal management system is involved, which generally includes three circulation loops, such as Figure 1 As shown, there are respectively a power battery circuit consisting of the power battery 14, electric heating device 32, electric cooling device 33, and second water pump 22; a drive motor circuit consisting of the drive motor 11, DC converter 12, onboard charger 13, generator 16, first water pump 21, first heat exchange device 41, and fan 31; and an engine circuit consisting of the engine 15, water pump 23, second heat exchange device 43, and fan 31. Here, the first water pump 21 and the second water pump 22 function to drive the cooling medium to flow in the cooling pipe 42; the first heat exchange device 41 and the second heat exchange device 43 function to exchange heat between the thermal management system and the outside atmosphere; the fan 31 functions to accelerate heat exchange between the heat exchange device and the atmosphere; and the electric heating device 32 and the electric cooling device 33 function to provide an electric heat source and an electric cooling source for the power battery 14.

[0053] Among them, the power battery circulation loop has functions such as power battery self-circulation, power battery cooling and power battery heating; the drive motor circulation loop has functions such as drive motor cooling, DC converter cooling, on-board charger cooling, and generator cooling; the engine circulation loop has engine cooling function.

[0054] Based on the above-mentioned thermal management system of new energy vehicles, the present disclosure provides a thermal management control method for new energy vehicles, such as Figure 2 As shown, it includes:

[0055] S101 , obtaining operating parameters and environmental parameters of a vehicle, wherein the operating parameters include at least the power level and the temperature of the power battery, and the environmental parameters include at least the current ambient temperature.

[0056] In this step, vehicle operating parameters and environmental parameters are acquired. The operating parameters include at least the power battery charge and the power battery temperature, and the environmental parameters include at least the current ambient temperature. The vehicle operating parameters, such as the power battery 14 charge and the power battery 14 temperature, can be acquired via sensors on the vehicle, particularly sensors on the power battery 14.

[0057] S102, determining whether the vehicle needs to be charged, and obtaining charging pile information when the power battery power is less than a first battery power threshold, the charging pile information including at least location information of the charging pile, type information of the charging pile, and distance information of the charging pile.

[0058] After obtaining the vehicle's operating parameters and environmental parameters through the above step S101, in this step, it is determined whether the vehicle needs to be charged. When the power level of the power battery is less than the first battery power threshold, the charging pile information is obtained. The charging pile information includes at least the location information of the charging pile, the type information of the charging pile, and the distance information of the charging pile.

[0059] Specifically, whether the vehicle needs to be charged can be determined by the power level of the power battery 14. For example, the power level of the power battery 14 can be compared with a first battery power threshold. When the power level of the power battery 14 is less than the first battery power threshold, it is considered that the vehicle needs to be charged.

[0060] In addition, in this step, the charging pile information is obtained through the navigation system on the vehicle. The charging pile information here at least includes, for example, the location information of the nearest charging pile, the type information of the charging pile, and the distance information between the current location of the vehicle and the charging pile, etc. The type information of the charging pile here is, for example, a DC charging pile or an AC charging pile; in specific practice, the navigation system can, for example, calculate and obtain the above-mentioned charging pile information based on the map data in the built-in memory or the map data obtained in real time from the cloud server.

[0061] S103: Adjusting the powertrain mode and heating / cooling method of the vehicle based on the operating parameters, the environmental parameters, and the charging pile information.

[0062] After obtaining the operating parameters and environmental parameters of the vehicle through the above step S101 and obtaining the charging pile information when the power level of the power battery is less than the first battery power threshold through the above step S102, in this step, the powertrain mode and heating / cooling method of the vehicle are adjusted based on the operating parameters, the environmental parameters and the charging pile information.

[0063] Specifically, in this step, when the vehicle needs to be charged, the heating effect of the vehicle's powertrain is analyzed based on the vehicle's driving conditions. Since the output power of the vehicle's power system is determined by the vehicle's driving conditions, different power outputs result in different powertrain efficiencies, that is, different power outputs, and correspondingly different power outputs. The temperature changes of the powertrain also affect the powertrain's operating efficiency. Thus, the vehicle controller controls the powertrain's temperature based on the temperature and remaining charge of the power battery 14, combined with information such as the distance between the vehicle and the charging station and the type of charging station.

[0064] With respect to step S103, adjusting the powertrain mode and heating / cooling mode of the vehicle based on the operating parameters, the environmental parameters, and the charging pile information, when the current ambient temperature and the temperature of the power battery are both low, includes:

[0066] S202: When the current ambient temperature is less than a first ambient temperature threshold, the temperature of the power battery is less than a first battery temperature threshold, and a DC charging pile is located at a first distance from the vehicle, and the first distance is greater than or equal to a second distance threshold, adjusting the powertrain mode to an engine series drive mode, controlling the engine's circuit cooling medium to heat the power battery, thereby ensuring rapid temperature rise of the power battery, thereby improving the power battery's charging capacity and shortening the charging time;

[0067] S203: When the current ambient temperature is less than a first ambient temperature threshold, the temperature of the power battery is less than a first battery temperature threshold, and there is an AC charging pile at a first distance from the vehicle, and the first distance is less than a first distance threshold, adjusting the powertrain mode to a pure electric mode and controlling an electric heating device in the vehicle to stop heating the power battery, thereby reducing power loss and charging costs.

[0068] S204: When the current ambient temperature is less than a first ambient temperature threshold, the temperature of the power battery is less than a first battery temperature threshold, and there is an AC charging pile at a first distance from the vehicle, and the first distance is greater than or equal to a second distance threshold, adjusting the powertrain mode to an engine series drive mode, controlling the engine's circuit cooling medium to heat the power battery, thereby ensuring rapid temperature rise of the power battery, improving the charging capacity of the power battery, reducing power loss, and reducing charging costs;

[0069] In addition, when the current ambient temperature and the temperature of the power battery are both high, the method further includes:

[0070] S205: When the current ambient temperature is greater than or equal to a second ambient temperature threshold, the temperature of the power battery is greater than or equal to a second battery temperature threshold, and a DC charging pile is located at a second distance from the vehicle, and the second distance is less than the first distance threshold, adjusting the powertrain mode to a pure electric mode and controlling an electric cooling device in the vehicle to cool the power battery at maximum power, thereby ensuring rapid cooling of the power battery, thereby improving charging capacity of the power battery and shortening charging time.

[0071] S206: When the current ambient temperature is greater than or equal to a second ambient temperature threshold, the temperature of the power battery is greater than or equal to a second battery temperature threshold, and a DC charging pile is located at a second distance from the vehicle, and the second distance is greater than or equal to the second distance threshold, adjusting the powertrain mode to an engine series drive mode, and controlling an electric cooling device in the vehicle to cool the power battery at a low power. This ensures that the power battery cools slowly, increases the driving range, and reaches a suitable charging temperature when the vehicle reaches the charging pile.

[0072] S207: When the current ambient temperature is greater than or equal to a second ambient temperature threshold, the temperature of the power battery is greater than or equal to a second battery temperature threshold, and there is an AC charging pile at a second distance from the vehicle, and the second distance is less than the first distance threshold, adjusting the powertrain mode to a pure electric mode and controlling an electric cooling device in the vehicle to stop cooling the power battery, thereby reducing power loss and charging costs.

[0073] S208, when the current ambient temperature is greater than or equal to a second ambient temperature threshold, the temperature of the power battery is greater than or equal to a second battery temperature threshold, and there is an AC charging pile at a second distance from the vehicle, and the second distance is greater than or equal to a second distance threshold, adjust the powertrain mode to the engine series drive mode, control the electric cooling device in the vehicle to stop cooling the power battery, thereby reducing power loss and charging costs.

[0074] In a specific embodiment, when the vehicle needs to be charged, for example, when the power level of the power battery is less than 30%, it is considered that charging is required. If the current ambient temperature is lower than -10°C, the temperature of the power battery is lower than -5°C, and there is a DC charging pile 10 kilometers ahead, the vehicle controller adopts a pure electric mode to drive, and controls the electric heating device 32 to heat the power battery 14 at maximum power to ensure that the power battery 14 heats up quickly to improve the charging capacity of the power battery 14 and shorten the charging time; if the current ambient temperature is lower than -10°C, the power battery level is lower than 30%, the power battery temperature is lower than -5°C, and there is a DC charging pile 20 kilometers ahead, the vehicle controller adopts an engine series drive mode to control the loop cooling medium of the engine 15 to heat the power battery 14 is heated to ensure that the power battery 14 heats up quickly, so as to improve the charging capacity of the power battery 14 and shorten the charging time; if the current ambient temperature is lower than -10°C, the power battery temperature is lower than -5°C, and there is an AC charging pile 10 kilometers ahead, the vehicle controller adopts the pure electric driving mode, controls the electric heating device 31 to stop heating the power battery 14, reduces power loss, and reduces charging costs; if the current ambient temperature is lower than -10°C, the power battery temperature is lower than -5°C, and there is an AC charging pile 20 kilometers ahead, the vehicle controller adopts the engine series drive mode, controls the loop cooling medium of the engine 15 to heat the power battery 14, ensures that the power battery 14 heats up quickly, so as to improve the charging capacity of the power battery 14, reduces power loss, and reduces charging costs.

[0075] In another specific embodiment, the current ambient temperature is higher than 30°C, the power battery temperature is higher than 30°C, and there is a DC charging pile 10 kilometers ahead, then the vehicle controller adopts the pure electric driving mode, controls the electric cooling device 33 to perform maximum power cooling on the power battery 14, ensures rapid cooling of the power battery 14, thereby improving the charging capacity of the power battery 14 and shortening the charging time; the current ambient temperature is higher than 30°C, the power battery temperature is higher than 30°C, and there is a DC charging pile 20 kilometers ahead, then the vehicle controller adopts the engine series driving mode, controls the electric cooling device 33 to perform low-power cooling on the power battery 14, ensures that the power battery 14 is cooled quickly, thereby improving the charging capacity of the power battery 14 and shortening the charging time; 4.

If the current ambient temperature is higher than 30°C, the power battery temperature is higher than 30°C, and there is an AC charging station 10 kilometers ahead, the vehicle controller adopts the pure electric driving mode and controls the electric cooling device 33 to stop cooling the power battery 14, thereby reducing power loss and charging costs. If the current ambient temperature is higher than 30°C, the power battery temperature is higher than 30°C, and there is an AC charging station 20 kilometers ahead, the vehicle controller adopts the engine series driving mode and controls the electric cooling device 33 to stop cooling the power battery 14, thereby reducing power loss and charging costs.

[0076] In another embodiment, the operating parameter further includes the temperature of the drive motor 11 in the vehicle. Here, the temperature of the drive motor 11 can also be obtained by a sensor device. The thermal management control method further includes:

[0077] S104 : When the power level of the power battery is greater than a second battery power threshold, obtaining future road condition information of the vehicle.

[0078] In this step, when the power level of the power battery is greater than the second battery power threshold, the future road condition information of the vehicle is obtained. Specifically, when the power level of the power battery 14 is greater than the second battery power threshold, it can be considered that the vehicle does not need to be charged. Further, for example, the future road condition information of the vehicle can be obtained through the navigation system of the vehicle, wherein the navigation system here can provide the vehicle controller with information such as the distance from the vehicle to the destination, the smoothness or congestion of the road ahead, etc., that is, it can provide future road condition information, for example, it can be achieved through the existing algorithm to obtain road condition information or call other third parties to obtain road condition information; in this way, through the analysis of future road condition information, the future power change of the vehicle's power system can be estimated, thereby predicting the temperature change trend of the power system, and finally adjusting the temperature control threshold in advance through the adjustment of the thermal management system control strategy, so that the temperature of the powertrain is accurately controlled within the ideal range.

[0079] S105 , adjusting the powertrain mode and heating / cooling method of the vehicle based on the operating parameters, the environmental parameters, and the future road condition information.

[0080] After obtaining future road condition information of the vehicle when the power battery charge level is greater than a second battery charge threshold in step S104, in this step, the vehicle's powertrain mode and heating / cooling method are adjusted based on the operating parameters, the environmental parameters, and the future road condition information. Specifically, in this step, when the vehicle does not require charging, future road condition information is obtained, for example, by the vehicle controller through the navigation system, thereby adjusting the thermal management control strategy.

[0081] Regarding step S105, adjusting the powertrain mode and heating / cooling method of the vehicle based on the operating parameters, the environmental parameters, and the future road condition information includes:

[0082] S301, when the current ambient temperature is less than a third ambient temperature threshold, the temperature of the power battery is less than a third battery temperature threshold, the temperature of the drive motor is less than a first motor temperature threshold, and the future road condition information indicates a clear road condition, before the power battery and the drive motor reach a preset cooling temperature, the electric cooling device in the vehicle is controlled in advance to cool the power battery and the drive motor separately so that the power battery and the drive motor operate within a preset temperature range. Specifically, under this operating condition, the vehicle requires continuous high power output, and therefore the power battery 14 and the drive motor 11 will continue to heat up. Before the power battery 14 and the drive motor 11 reach the temperature at which they need to be cooled, the vehicle controller controls the cooling of the power battery 14 and the drive motor 11 in advance, thereby ensuring that the power battery 14 and the drive motor 11 operate within the ideal temperature range and improving the operating efficiency of the entire vehicle.

[0083] S302: When the current ambient temperature is greater than or equal to a fourth ambient temperature threshold, the temperature of the power battery is greater than or equal to a fourth battery temperature threshold, the temperature of the drive motor is greater than or equal to a second motor temperature threshold, and the future road condition information indicates a clear road condition, the vehicle's electric cooling device is controlled in advance to cool the power battery and the drive motor separately and gradually increase the cooling power before the power battery and the drive motor reach a preset cooling temperature, so that the power battery and the drive motor operate within a preset temperature range. Specifically, under this operating condition, continuous high power output is required, and therefore the power battery 14 and the drive motor 11 will be continuously in a high temperature state. The vehicle controller controls the cooling of the power battery 14 and the drive motor 11 in advance and increases the cooling power to ensure that the power battery 14 and the drive motor 11 operate within the ideal temperature range, thereby improving the operating efficiency of the vehicle.

[0084] Also includes:

[0085] S303: When the current ambient temperature is less than a third ambient temperature threshold, the power battery temperature is less than a third battery temperature threshold, the drive motor temperature is less than a first motor temperature threshold, and future road condition information indicates congested traffic, the vehicle's electric cooling device is controlled to cool the drive motor in advance before the drive motor reaches a preset cooling temperature. In this case, the required power is low, but the drive motor 11 has low operating efficiency, resulting in high heat generation power, which may cause the drive motor 11 to overheat. The vehicle controller cools the drive motor 11 in advance to ensure that the drive motor 11 operates within an ideal temperature range.

[0086] S304: When the current ambient temperature is greater than or equal to a fourth ambient temperature threshold, the power battery charge is greater than or equal to a second battery charge threshold, the power battery temperature is greater than or equal to a fourth battery temperature threshold, the drive motor temperature is greater than or equal to a second motor temperature threshold, and future road condition information indicates congested road conditions, the electric cooling device in the vehicle is controlled in advance to cool the drive motor and gradually increase the cooling power before the drive motor reaches a preset cooling temperature. Specifically, under this operating condition, the required power is low, but the operating efficiency of the drive motor 11 is low, resulting in a high heat generation power, which may cause the drive motor 11 to overheat. The vehicle controller cools the drive motor 11 in advance and increases the cooling power to ensure that the drive motor 11 operates within an ideal temperature range.

[0087] In a specific embodiment, when the vehicle needs to be charged, for example, when the power level of the power battery 14 is higher than 30%, the current ambient temperature is lower than -10°C, the temperature of the power battery 14 is lower than -5°C, and the temperature of the drive motor 11 is lower than -5°C. The future driving condition is a section of highway operation, which requires continuous high power output. Therefore, the power battery 14 and the drive motor 11 will continue to heat up. Before the power battery 14 reaches 35°C and the drive motor 11 reaches 55°C, the vehicle controller controls the power battery 14 and the drive motor 11 to cool down in advance, thereby ensuring that the power battery 14 and the drive motor 11 operate within an ideal temperature range and improving the operating efficiency of the vehicle. The current ambient temperature is higher than 30°C, the temperature of the power battery 14 is higher than 35°C, and the temperature of the drive motor 11 is higher than 55°C. The future driving condition is a section of highway operation, which requires continuous high power output. Therefore, the power battery 14 and the drive motor 11 will continue to be in a high temperature state. The vehicle controller controls the cooling of the power battery 14 and the drive motor 11 in advance, increases the rotation speed of the first water pump 22 and the fan 31, and improves the power of the electric refrigeration device 33, which can ensure that the power battery 14 and the drive motor 11 operate within the ideal temperature range and improve the working efficiency of the vehicle; the current ambient temperature is lower than -10°C, the temperature of the power battery 14 is lower than -5°C, and the temperature of the drive motor 11 is lower than -5°C. The future driving road condition is a congested road condition. The power required for this working condition is low, but the working efficiency of the drive motor 11 is low, so the heat generation power is large, which will cause the drive motor 11 to overheat. Before the drive motor 11 reaches 55°C, the The vehicle controller cools the drive motor 11 in advance to ensure that the drive motor 11 operates within an ideal temperature range; the current ambient temperature is higher than 30°C, the temperature of the power battery 14 is higher than 35°C, and the temperature of the drive motor 11 is higher than 55°C. The future driving road condition is a congested road condition. The power required for this working condition is low, but the working efficiency of the drive motor 11 is low, so the heat generation power is large, which will cause the drive motor 11 to overheat. Before the drive motor 11 reaches 55°C, the vehicle controller cools the drive motor 11 in advance and increases the speed of the first water pump 22 and the fan 31 to ensure that the drive motor 11 operates within the ideal temperature range.
