Separator, furthermore the vapour liquid separator connects the vehicle external heat exchanger A by the second electromagnetism two-port valve；First interior heat exchanger
PTC electric heating is equipped with the second interior heat exchanger side；
Battery coolant liquid circulation: battery coolant liquid water circulating pump successively the first coolant system three-way solenoid valve, battery pack,
Second coolant system three-way solenoid valve, vehicle external heat exchanger B, coolant system expansion tank form circulation loop, wherein first
Coolant system three-way solenoid valve is also sequentially connected the Intermediate Heat Exchanger and battery pack；
The electric control coolant liquid circulation: electric control water circulating pump is sequentially connected entire car controller, vehicle driving motor, vehicle
External heat exchanger C, electric control expansion tank form circulation loop.
3. a kind of integrated battery based on heat pump air conditioner as claimed in claim 2, motor, automatically controlled integrated thermal management system,
It is characterized in that, the described first interior heat exchanger and the second interior heat exchanger side cascaded H VAC internal exchanger replacement PTC electricity add
Heat, HVAC internal exchanger can replace PTC using heat pump air conditioner exhaust gas heat.
4. a kind of integrated battery based on heat pump air conditioner as claimed in claim 2, motor, automatically controlled integrated thermal management system,
It is characterized in that, the electric control coolant liquid circulation: increasing auxiliary PTC electric heating, electric control electromagnetism two-port valve and warm wind
Core realizes the recuperation of heat of electric control；If the heat dissipation of warm wind core is insufficient, the vehicle external heat exchanger C and warm wind core parallel connection heat dissipation；If
Coolant temperature before into electric control is not high, then directly carries out recuperation of heat by warm wind core.
