[0075] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0076] The following description, with reference to the accompanying drawings, outlines a thermal management method, apparatus, vehicle, electronic device, and storage medium according to embodiments of the present disclosure.

[0077] Figure 1 This is a schematic flowchart of a thermal management method provided in an embodiment of the present disclosure.

[0078] like Figure 1 As shown, the method includes the following steps:

[0079] Step 101: After receiving the heating request, confirm the target vehicle's driving mode and confirm each heat source according to the target vehicle's driving mode.

[0080] Heating requests can be issued by the vehicle's infotainment system or by the occupants of the target vehicle via a human-machine interface. This application does not limit the specific requests in this embodiment.

[0081] The driving mode may be range-extended mode, pure electric mode or engine mode, and this application embodiment does not limit this.

[0082] Step 102: Determine the target heat source that meets the heating conditions according to the priority order of each heat source; wherein the priority order of the heat sources is as follows: engine cooling water circuit, battery cooling / heating circuit, electric drive cooling water circuit, electric heater, wherein the electric heater and auxiliary heat source jointly perform heating.

[0083] After determining the heat sources corresponding to the current target vehicle's driving mode, the heat sources are sequentially checked for compliance with heating conditions according to their priority. If the heating conditions are met, the current heat source is determined as the target heat source, without the need to compare all heat sources sequentially. It should be noted that different heat sources correspond to different heating conditions, and the heating conditions are empirical values ​​that can be set according to actual needs. Specifically, this application embodiment does not limit this.

[0084] Step 103: After determining the target heat source that meets the heating conditions according to the priority order, in response to the heating request, heating is performed based on the target heat source.

[0085] The thermal management method disclosed herein mainly includes the following technical solutions: after receiving a heating request, confirming the target vehicle's driving mode; confirming each heat source according to the target vehicle's driving mode, and determining a target heat source that meets the heating conditions according to the priority order of each heat source; wherein the priority order of the heat sources is as follows: engine cooling water circuit, battery cooling / heating circuit, electric drive cooling water circuit, and electric heater, wherein the electric heater and auxiliary heat source jointly perform heating; after determining the target heat source that meets the heating conditions according to the priority order, responding to the heating request, performing heating based on the target heat source. Compared with related technologies, the embodiments of this application prioritize the heat sources corresponding to the driving mode, and after receiving a heating request, determine the target heat source according to the priority order of the heat sources corresponding to the current driving mode and the conditions corresponding to the heat sources. The target heat source is used for heating. The various heat sources in the vehicle (engine cooling water circuit, battery cooling / heating circuit, electric drive cooling water circuit, electric heater) are used as heat sources. When using the electric heater for heating, an auxiliary heat source is used for auxiliary heating, which reduces the power consumption of the electric heater, saves vehicle power, and improves the driving range of the vehicle in pure electric mode.

[0086] In one possible implementation of this application embodiment, please refer to Figure 2 , Figure 2 This is a schematic diagram of a target heat source determination process provided in an embodiment of this application, as shown below. Figure 2 As shown, Figure 2 Whether the vehicle is in range-extending mode is the same as the vehicle driving mode confirmed in this application embodiment. Different driving modes have different power sources, and therefore correspond to different heat sources. Therefore, after confirming the driving mode of the target vehicle, it is necessary to first confirm the corresponding heat source. The specific steps are as follows: if the driving mode of the target vehicle is determined to be range-extending mode, the heat source in the range-extending mode is determined to be a combination of one or more heat sources among the engine cooling water circuit, electric heater and electric drive water circuit, according to the preset heat source determination rules.

[0087] Following the description of the above embodiments, after determining the heat source corresponding to the range-extended mode, the target heat source is determined according to the priority order of each heat source; please refer to... Figure 3 , Figure 3 This is a flowchart illustrating a thermal management method provided in an embodiment of the present disclosure. When the heating request includes at least one of an air conditioning heating request and a battery heating request, it includes:

[0088] Step 201: Determine whether the water temperature of the engine cooling water circuit is greater than or equal to the preset battery target water temperature.

[0089] In range-extended operation, the priority order of each heat source is engine cooling water circuit > electric drive water circuit > electric heater. Therefore, when determining the target heat source, it is first determined whether the engine cooling water circuit meets the heating conditions. The preset target battery water temperature is an empirical value, which varies depending on the target temperature of the battery. This application embodiment does not limit the setting of the preset target battery water temperature.

[0090] Step 202: If it is determined that the water temperature of the engine cooling water circuit is greater than or equal to the preset target water temperature of the battery, then the engine cooling water circuit is determined to be the target heat source for the air conditioner heater and the battery.

[0091] Step 203: If it is determined that the water temperature of the engine cooling water circuit is less than the preset battery target water temperature, then determine whether the water temperature of the engine cooling water circuit is greater than or equal to the preset air conditioning target water temperature, wherein the preset battery target water temperature is greater than the preset air conditioning target water temperature.

[0092] In range-extended operation, when both air conditioning and battery heating requests exist simultaneously, the engine coolant circuit prioritizes supplying the air conditioning heating circuit. The preset target air conditioning coolant temperature is an empirical value, which can be determined based on the air conditioning heating temperature setting, fan speed, etc. For example, if the air conditioning heating temperature setting is 24 degrees Celsius and the fan speed is set to level 3, the preset target air conditioning coolant temperature can be set to 76 degrees Celsius, and the preset target battery coolant temperature can be set to 80 degrees Celsius. It should be noted that the above data settings are only illustrative examples and are not intended to limit specific parameters. This application embodiment does not impose any limitations on these parameters.

[0093] Step 204: If it is determined that the water temperature of the engine cooling water circuit is greater than or equal to the preset air conditioning target water temperature, then the engine cooling water circuit is determined to be the target heat source for the air conditioning heating, and the electric drive cooling water circuit is determined to be the target heat source for the battery.

[0094] Please continue reading. Figure 2 , Figure 2 In Mode 1, the engine cooling water circuit is designated as the target heat source for the air conditioning heater, and the electric drive cooling water circuit is designated as the target heat source for the battery. Figure 2 The statement regarding whether the engine coolant outlet temperature is greater than the target air conditioning temperature refers to determining whether the engine cooling water circuit temperature is greater than or equal to the preset target air conditioning temperature.

[0095] Step 205: If the water temperature of the engine cooling water circuit is lower than the preset air conditioning target water temperature, then the engine cooling water circuit and the electric heater are determined to be the target heat source for the air conditioning heating, and the electric drive cooling water circuit is determined to be the target heat source for the battery.

[0096] Please continue reading. Figure 2 , Figure 2 Mode 2 in the text refers to determining the engine cooling water circuit and the electric heater as the target heat source for the air conditioning heating, and determining the electric drive cooling water circuit as the target heat source for the battery; when the water temperature of the engine cooling water circuit is lower than the preset air conditioning target water temperature, the electric heater is used for auxiliary heating to make the water temperature greater than or equal to the air conditioning target water temperature, thereby achieving heating for the air conditioning heating.

[0097] In one possible implementation of this application, the electric heater may be a water heater (WaterPositiveCoefficient, WPCT) or a resistance wire heater, etc., and this application does not limit this.

[0098] In one possible implementation of this application embodiment, when the target vehicle's driving mode is determined to be pure electric mode, the heat source in pure electric mode is determined to be a combination of one or more heat sources selected from the battery cooling / heating circuit, the electric drive cooling water circuit, and the electric heater, according to the preset heat source determination rules. After confirming the heat source corresponding to the driving mode, the target heat source is confirmed according to the priority order of each heat source; please refer to [link to relevant documentation]. Figure 4 , Figure 4 A schematic flowchart of a thermal management method provided in this embodiment of the present disclosure includes:

[0099] Step 301: Determine whether the water temperature of the battery cooling / heating circuit is greater than or equal to a preset battery temperature threshold.

[0100] Please continue reading. Figure 2 , Figure 2 A battery temperature > 25°C is equivalent to determining whether the water temperature of the battery cooling / heating circuit is greater than or equal to a preset battery temperature threshold, as described in this application embodiment. It should be noted that... Figure 2 The battery temperature >25°C mentioned is merely an illustrative example and is not a limitation on a specific preset battery temperature threshold. The preset battery temperature threshold is an empirical value that can be set according to the battery operating temperature, ambient temperature, etc. This application embodiment does not limit this.

[0101] Step 302: If it is determined that the water temperature of the battery cooling / heating circuit is greater than or equal to a preset battery temperature threshold, then the battery cooling / heating circuit and the electric heater are determined to be the target heat source for the air conditioner's warm air.

[0102] Please continue reading. Figure 2 , Figure 2 In Mode 3, the battery cooling / heating circuit and the electric heater described in this application embodiment serve as the target heat source for the air conditioner's warm air. Since the water temperature in the battery cooling / heating circuit is too low to meet the air conditioner's heating requirements, an electric heater is needed to assist in heating so that the water temperature reaches the preset target air conditioner water temperature, thereby achieving the heating of the air conditioner's warm air.

[0103] Step 303: If it is determined that the water temperature of the battery cooling / heating circuit is less than the preset battery temperature threshold, then determine whether the water temperature of the electric drive cooling water circuit is greater than or equal to the preset electric drive cooling water circuit temperature threshold.

[0104] Please continue reading. Figure 2 , Figure 2 The electric drive circuit water temperature minus ambient temperature > 10°C and > -10°C is the condition described in this embodiment for determining whether the water temperature of the electric drive cooling water circuit is greater than or equal to a preset electric drive cooling water circuit temperature threshold. The preset electric drive cooling water circuit temperature threshold is an empirical value, which can be set according to the ambient temperature and the vehicle's electric drive operating conditions. For example, it can be set to... Figure 2 The electric drive circuit described herein has a water temperature - ambient temperature > 10°C and > -10°C. It should be noted that... Figure 2 The determination criteria described are merely illustrative and are not intended to limit the preset electric drive cooling water circuit temperature threshold. This application does not limit such criteria.

[0105] In one possible implementation of this application embodiment, if it is determined that the water temperature of the battery cooling / heating circuit is less than a preset battery temperature threshold, the battery cooling / heating circuit is controlled to circulate and store heat until the water temperature of the battery cooling / heating circuit is greater than or equal to the preset battery temperature threshold, and then the battery cooling / heating circuit and the electric heater are redefined as the target heat source for the air conditioner's heating.

[0106] Step 304: If it is determined that the water temperature of the electrically driven cooling water circuit is greater than or equal to the preset temperature threshold of the electrically driven cooling water circuit, then the electrically driven cooling water circuit and the electric heater are determined to be the target heat source for the air conditioning heating.

[0107] Please continue reading. Figure 2 , Figure 2 Mode 4 in this application embodiment refers to determining the electric drive cooling water circuit and the electric heater as the target heat source for the air conditioner's warm air. The water temperature of the electric drive cooling water circuit is low, lower than the preset target water temperature for the air conditioner. Therefore, an electric heater is needed to assist in heating so that the water temperature meets the requirements of the air conditioner's warm air, thereby achieving the heating of the air conditioner's warm air.

[0108] In one possible implementation of this application embodiment, if it is determined that the water temperature of the electric drive cooling water circuit is less than a preset electric drive cooling water circuit temperature threshold, then the electric drive cooling water circuit is controlled to circulate and store heat until the water temperature of the vehicle's electric drive water circuit is greater than or equal to the preset vehicle electric drive water circuit temperature threshold. Afterward, the electric drive water circuit and the electric heater are redefined as the target heat source for the air conditioning heating. Please continue reading. Figure 2 , Figure 2 Mode 7 in the present application is the electrically driven cooling water circuit circulation heat storage in the embodiment of this application.

[0109] Step 305: If it is determined that the water temperature of the electrically driven cooling water circuit is less than the preset temperature threshold of the electrically driven cooling water circuit, then the electric heater is determined to be the target heat source for the air conditioner's warm air.

[0110] Please continue reading. Figure 2 , Figure 2 Mode 5 described in the present application refers to the electric heater in this embodiment serving as the target heat source for the air conditioner's heating air.

[0111] In one possible implementation of this application embodiment, the electric heater consumes a large amount of battery power; therefore, when using the electric heater, it is necessary to further determine whether other heat sources are available. Please refer to [link to relevant documentation]. Figure 2 , Figure 2 A central ambient temperature < -10°C is used in this embodiment to determine whether the ambient temperature outside the vehicle is greater than or equal to a preset ambient temperature threshold. If the ambient temperature outside the vehicle is determined to be greater than or equal to the preset ambient temperature threshold, then the electric heater and the auxiliary heat source are determined to be the target heat source for the air conditioning heating. In one possible implementation of this embodiment, the auxiliary heat source can be an air heat pump, and the preset ambient temperature threshold is an empirical value that can be set according to the heat pump's operating conditions, such as being set to... Figure 2 The ambient temperature shown is <-10℃, etc. It should be noted that... Figure 2 The ambient temperature shown as <-10°C is merely an illustrative example and is not a specific limitation on the preset ambient temperature threshold. This application does not limit this aspect. Figure 2 Mode 6 in this application embodiment is the determination of the electric heater and air heat pump as the target heat source for the air conditioner's heating air.
