[0087] In an implementation manner of the embodiment of the present application, please refer to FIG. 2, which is a schematic diagram of a judgment flow of a target heating source provided by the embodiment of the present application, as shown in FIG. 2, whether the range extending mode is the target vehicle driving mode confirmed in the embodiment of the present application; different driving modes have different power sources, so different heating sources are corresponded, therefore after the target vehicle driving mode is confirmed, the corresponding heating source is first confirmed, and the specific steps are as follows: in the case that the target vehicle driving mode is the range extending mode, the heating source in the range extending mode is determined to be a combination of one or more of the engine cooling water circuit, the electric heater and the electric drive water circuit according to a preset heating source determination rule.

[0088] According to the above embodiment, after the heating source corresponding to the range extending mode is determined, the target heating source is determined according to the priority order of each heating source; please refer to FIG. 3, which is a schematic diagram of a heat management method provided by the embodiment of the present disclosure. When the heating request comprises at least one of the air conditioner warm air request and the battery heating request, it comprises:

[0089] Step 201: judging whether the water temperature of the engine cooling water circuit is greater than or equal to a preset battery target water temperature.

[0090] In the extended range working condition, the priority order of each heat supply source is engine cooling water circuit > electric driving water circuit > electric heater, so when determining the target heat supply source, it is preferred to determine whether the engine cooling water circuit meets the heat supply condition; the preset battery target water temperature is an empirical value, which is different according to the target temperature of the battery, and the preset battery target water temperature is not limited in the embodiment of the application.

[0091] Step 202, if it is determined that the water temperature of the engine cooling water circuit is greater than or equal to the preset battery target water temperature, the engine cooling water circuit is determined as the target heat supply source of the air conditioner warm air and the battery.

[0092] 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, it is determined whether the water temperature of the engine cooling water circuit is greater than or equal to the preset air conditioner target water temperature, wherein the preset battery target water temperature is greater than the preset air conditioner target water temperature.

[0093] In the extended range working condition, when the air conditioner warm air request and the battery warm air request exist simultaneously in the heating request, the engine cooling water circuit preferentially supplies the air conditioner warm air circuit; the preset air conditioner target water temperature is an empirical value, which can be determined according to the air conditioner warm air setting temperature, air speed and the like, for example, the air conditioner warm air setting temperature is 24, the air speed is set to 3 gears, and the preset air conditioner target water temperature can be set to 76 degrees, and the preset battery target water temperature can be set to 80 degrees; it should be noted that the above data setting is only an exemplary description, and is not a limitation on specific parameters, and the preset battery target water temperature is not limited in the embodiment of the application.

[0094] 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 conditioner target water temperature, the engine cooling water circuit is determined as the target heat supply source of the air conditioner warm air, and the electric driving cooling water circuit is determined as the target heat supply source of the battery.

[0095] Please continue to refer to FIG. 2, mode 1 in FIG. 2 is that the engine cooling water circuit is the target heat supply source of the air conditioner warm air, and the electric driving cooling water circuit is determined as the target heat supply source of the battery, and whether the engine outlet water temperature > air conditioner target water temperature in FIG. 2 is to determine whether the water temperature of the engine cooling water circuit is greater than or equal to the preset air conditioner target water temperature.

[0096] Step 205, if the water temperature of the engine cooling water circuit is less than the preset air conditioner target water temperature, the engine cooling water circuit and the electric heater are determined as the target heat supply source of the air conditioner warm air, and the electric driving cooling water circuit is determined as the target heat supply source of the battery.

[0097] Please continue to refer to FIG. 2, mode 2 in FIG. 2 is that the engine cooling water circuit and the electric heater are determined as the target heat source of the air conditioner warm air, and the electric drive cooling water circuit is determined as the target heat source of the battery; when the water temperature of the engine cooling water circuit is less than the preset air conditioner target water temperature, the electric heater is used for auxiliary heating, so that the water temperature is greater than or equal to the air conditioner target water temperature, and the heat supply to the air conditioner warm air is realized.

[0098] In an implementable manner of the embodiment of the present application, the electric heater can be a water heater (Water Positive Coefficient, WPCT) or a resistance wire heater, and the embodiment of the present application does not limit this.

[0099] In an implementable manner of the embodiment of the present application, in a case where the target vehicle driving mode is determined as the pure electric mode, according to the preset heat source determination rule, the heat source in the pure electric mode is determined as a combination of one or more heat sources of the battery cooling / heating circuit, the electric drive cooling water circuit and the electric heater. 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 FIG. 4, which is a flowchart of a heat management method provided by the embodiment of the present application, including:

[0100] Step 301, determining whether the water temperature of the battery cooling / heating circuit is greater than or equal to a preset battery temperature threshold.

[0101] Please continue to refer to FIG. 2, battery temperature> 25 in FIG. 2 is that the water temperature of the battery cooling / heating circuit is determined whether it is greater than or equal to the preset battery temperature threshold; it should be noted that the battery temperature> 25 in FIG. 2 is only an example for illustration, and is not a limitation on the specific preset battery temperature threshold. The preset battery temperature threshold is an empirical value, which can be set according to the battery working temperature, the environment temperature and the like, and the embodiment of the present application does not limit this.

[0102] Step 302, if it is determined that the water temperature of the battery cooling / heating circuit is greater than or equal to the preset battery temperature threshold, then the battery cooling / heating circuit and the electric heater are determined as the target heat source of the air conditioner warm air.

[0103] Please continue to refer to FIG. 2, mode 3 in FIG. 2 is that the battery cooling / heating circuit and the electric heater are the target heat source of the air conditioner warm air; because the water temperature of the battery cooling / heating circuit is low, it cannot meet the air conditioner heating demand, so the electric heater needs to be used for auxiliary heating, so that the water temperature reaches the preset air conditioner target water temperature, to realize the heating of the air conditioner warm air.

[0104] Step 303, if it is determined that the water temperature of the battery cooling / heating circuit is less than the preset battery temperature threshold, it is determined 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.

It should be noted that the determination condition in FIG. 2 is only an exemplary description, and is not a specific limitation on the preset electric drive cooling water circuit temperature threshold. The embodiment of the application does not limit this.

[0106] In an implementable manner of the embodiment of the application, if it is determined that the water temperature of the battery cooling / heating circuit is less than the preset battery temperature threshold, the battery cooling / heating circuit is controlled to circulate heat storage 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 re-determined as the target heat source of the air conditioning warm air.

[0107] Step 304, if it is determined that 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, the electric drive cooling water circuit and the electric heater are determined as the target heat source of the air conditioning warm air.

[0108] Please continue to refer to FIG. 2, mode 4 in FIG. 2 is the determination of the electric drive cooling water circuit and the electric heater as the target heat source of the air conditioning warm air in the embodiment of the application. The water temperature of the electric drive cooling water circuit is low, which is less than the preset air conditioning target water temperature, so the electric heater needs to be used for auxiliary heating to make the water temperature meet the demand of the air conditioning warm air, so as to realize the heat supply to the air conditioning warm air.

[0109] In an implementable manner of the embodiment of the application, if it is determined that the water temperature of the electric drive cooling water circuit is less than the preset electric drive cooling water circuit temperature threshold, the electric drive cooling water circuit is controlled to circulate heat storage until the water temperature of the vehicle electric drive water circuit is greater than or equal to the preset vehicle electric drive water circuit temperature threshold, and then the electric drive water circuit and the electric heater are re-determined as the target heat source of the air conditioning warm air. Please continue to refer to FIG. 2, mode 7 in FIG. 2 is the electric drive cooling water circuit heat storage in the embodiment of the application.

[0110] Step 305, if it is determined that the water temperature of the electrically driven cooling water circuit is less than the preset electrically driven cooling water circuit temperature threshold, it is determined that the electric heater is the target heat source of the air conditioning warm air.

[0112] In an implementable manner of the embodiment of the application, the electric heater consumes a large amount of battery power, so when the electric heater is used, it is further determined whether there is still another heat source available; please refer to FIG. 2, ring temperature <-10 in FIG. 2 is to determine whether the ambient temperature outside the vehicle is greater than or equal to the preset ambient temperature threshold in the embodiment of the application; if it is determined that the ambient temperature outside the vehicle is greater than or equal to the preset ambient temperature threshold, it is determined that the electric heater and the auxiliary heat source are the target heat source of the air conditioning warm air.
