In the battery temperature control system, when electronlmobil starts, need carry out preheating to battery pack (6), battery temperature control system electric oil pump (2) starts, oil coolant in battery temperature control system oil storage kettle (1) is under the port one of the first three-way joint oil valve (3) port one, the 3 and the 3rd three-way joint oil valve (7), 3 control, enter high pressure P TC(9) locate high pressure P TC(9) by after the oil coolant heating, oil coolant flows back to battery pack (6) to its preheating; After electronlmobil is stable, battery pack (6) needs heat radiation, oil coolant is under the first three-way joint oil valve (3) port one, the 2 and second three-way joint oil valve (4) port one, 3 control, entering heat exchanger (10) heat exchange, to flow back to battery pack (6) after cooling cooling to it, flows back to afterwards battery temperature control system oil storage kettle (1) and form circulation;
In the miscellaneous part coolant circulation system, after electronlmobil is stable, electric machine controller (15), motor (16), inverter (17) needs heat radiation, miscellaneous part coolant circulation system electric oil pump (12) starts, oil coolant in miscellaneous part coolant circulation system oil storage kettle (11) is at the 4th three-way joint oil valve (13) port one, under 3 controls, enter heat exchanger (10) heat exchange cooling, flow through successively afterwards electric machine controller (15), motor (16), inverter (17) is got back to miscellaneous part coolant circulation system oil storage kettle (11), realize circulating cooling,
In air conditioner circulating system, compressor (18) work, refrigerant is controlled by the 5th three-way joint oil valve (19) port one, 3, flow into car inner condenser (26) through the 3rd expansion valve (25) and locate the condensation heat release, liberated heat is blown into heating in compartment by blowing engine in car (28), afterwards through the first expansion valve (21) into the car evaporator (22) locate evaporation endothermic, the condenser after heat absorption is again got back to compressor (18) and is formed circulation; Wherein, the circulation loop that the heat that in car, evaporator (22) locates to absorb forms from water storage bottle (29), electric water pump (30), evaporator (22), heat exchanger (10) and the heat after heat exchanger (10) heat exchange, the heat in heat exchanger (10) is from the High-temperature cooling oil in battery temperature control system and other parts coolant circulation systems.
