Title:
ELECTRIC VEHICLE THERMAL MANAGEMENT SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/155847
Kind Code:
A1
Abstract:
An electric vehicle thermal management system, comprising a water tank (1), a liquid-gas separator (2), a four-way valve (3), a first water pump (4), a second water pump (5), a battery water jacket (6), an electric appliance water jacket (7) which is simultaneously used for a voltage converter (71) and a vehicle-mounted charger (72), a radiator (8), a heat exchanger main body (91) of a battery cooler (9), an electric motor controller water jacket (10) and/or an electric motor water jacket (11). The four-way valve (3) comprises a first valve port, a second valve port, a third valve port and a fourth valve port. An outlet of the radiator (8) and the water tank (1) are both in communication with the first valve port. The second valve port, the heat exchanger main body (91), the liquid-gas separator (2), the first water pump (4), the battery water jacket (6) and the third valve port are sequentially in communication with each other, and the first water pump (4) is used for pumping a cooling liquid of the liquid-gas separator (2) into the battery water jacket (6). The fourth valve port, the second water pump (5), the electric appliance water jacket (7), the electric motor water jacket (11) and/or the electric motor controller water jacket (10), and an inlet of the radiator (8) are sequentially in communication with each other; and the second water pump (5) is used for pumping a cooling liquid flowing out of the fourth valve port into the electric appliance water jacket (7). Further provided is a vehicle. The electric vehicle thermal management system and the vehicle can reduce the number of system parts, thereby simplifying the system and reducing the cost.
