The temperature parameters include battery temperature, ambient temperature, and battery temperature difference. The temperature parameters comprise battery temperature, ambient temperature and battery temperature difference, the battery temperature difference refers to the temperature difference between different areas of the battery, and when the battery temperature difference is too large, the battery is easily damaged, and the service life and the efficiency of the battery are influenced.

Then flows into the eight-way valve 121 from port VI and flows out from port VII to return to the condenser 126 for further heat exchange.
Because the heat of the air flow generated by the air conditioner blower 114 is absorbed by the evaporator 115 by the heat exchange medium in the air conditioner refrigeration loop, the moisture in the air flow is condensed into liquid water when meeting the condensation and is discharged out of the vehicle, thereby reducing the moisture content in the passenger compartment and achieving the dehumidification effect. Meanwhile, as the heat exchange medium in the thermal regulation loop is discharged from the heating and ventilation core 116 to heat the air flow generated by the air conditioner blower 114, the heat absorbed by the heat exchange medium in the air conditioner refrigeration loop in the evaporator 115 is compensated, the temperature in the passenger cabin can be kept stable while dehumidification is performed, and the heating and dehumidification effects are achieved.
32. When the vehicle working condition is a normal load working condition, the ambient temperature: -15 ℃ to 10 ℃, cell temperature: when the temperature difference is more than 10 ℃ and the working condition of the air conditioner of the passenger compartment is heating, the temperature regulation requirement of the passenger compartment can be determined to be heating, the battery temperature regulation requirement is temperature equalization, and the electric driving temperature regulation requirement is cooling. At this time, port i of the eight-way valve 121 is connected to port iii, port ii is connected to port viii, port iv is connected to port v, and port vi is connected to port vii.
The first valve 113 is open and the second valve 123 is open; the first water pump 118 is operated, the third water pump 130 is stopped, and the second water pump 125 is operated; the ports a and C of the second three-way valve 119 are connected, and the ports b and C of the first three-way valve 117 are connected.
The heat exchange medium in the battery temperature regulation loop enters the battery pack 132 under the action of the third water pump 130 to absorb heat for the battery pack 132, the heat exchange medium after absorbing heat flows into the eight-way valve 121 from the port VIII and flows out from the port II, the heat exchange medium flowing out from the port II reenters the battery pack 132 under the action of the third water pump 130 to continue cooling the battery pack 132, and the temperature of the battery pack 132 is uniform when the heat exchange medium in the battery temperature regulation loop circulates through the battery pack 132.
The heat exchange medium in the electrically-driven temperature regulating loop directly enters the electrically-driven part from the beta port and the gamma port of the third three-way valve through the b port and the c port of the first three-way valve 117 and the second bypass pipeline 105 under the action of the first water pump 118, and the heat exchange medium absorbs heat through the front electrically-driven part 110 and the rear electrically-driven part 111 respectively to cool the front electrically-driven part 110 and the rear electrically-driven part 111. The heat-absorbed heat exchange medium enters the eight-way valve 121 from the port I and flows out from the port III to enter the battery cooler 124 to exchange heat with the heat exchange medium in the air-conditioning refrigeration loop to release heat. The heat-released heat-exchange medium enters the eight-way valve 121 from the port IV and flows out from the port V to return to the first water pump 118.
Part of the heat exchange medium in the air-conditioning refrigeration loop exchanges heat with the heat exchange medium in the electrically-driven temperature regulating loop in the battery cooler 124, enters the compressor 128 through the gas-liquid separator 133 after absorbing heat, enters the condenser 126 after being compressed by the compressor 128, exchanges heat with the heat exchange medium in the heat regulating loop in the condenser 126, and releases heat. The heat-released heat exchange medium is returned to the battery cooler 124 via the second valve 122.
Meanwhile, after the evaporator 115 absorbs the heat of the air flow generated by the air conditioner blower 114, the heat exchange medium in another part of the air conditioner refrigeration loop enters the compressor 128 through the gas-liquid separator 133, the heat exchange medium flows into the condenser 126 after being compressed by the compressor 128, exchanges heat with the heat exchange medium in the thermal regulation loop, and then returns to the evaporator 115 through the first valve 113 to continuously absorb the heat of the air flow generated by the air conditioner blower 114.
After the heat exchange medium in the thermal regulation loop exchanges heat with the heat exchange medium in the air-conditioning refrigeration loop through the condenser 126, the heat exchange medium enters the heating and ventilation core 116 through the port a and the port C of the second three-way valve 119 to dissipate heat under the action of the second water pump 125, so as to heat the air flow generated by the air-conditioning blower 114. Then flows into the eight-way valve 121 from port VI and flows out from port VII to return to the condenser 126 for further heat exchange.
Because the heat of the air flow generated by the air conditioner blower 114 is absorbed by the evaporator 115 by the heat exchange medium in the air conditioner refrigeration loop, the moisture in the air flow is condensed into liquid water when meeting the condensation and is discharged out of the vehicle, thereby reducing the moisture content in the passenger compartment and achieving the dehumidification effect. Meanwhile, as the heat exchange medium in the thermal regulation loop is discharged from the heating and ventilation core 116 to heat the air flow generated by the air conditioner blower 114, the heat absorbed by the heat exchange medium in the air conditioner refrigeration loop in the evaporator 115 is compensated, the temperature in the passenger cabin can be kept stable while dehumidification is performed, and the heating and dehumidification effects are achieved.
