Title:
THERMAL MANAGEMENT SYSTEM AND METHOD FOR A VEHICLE EQUIPPED WITH AN SOFC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/012323
Kind Code:
A1
Abstract:
The invention discloses a vehicle thermal management system equipped with an SOFC system. The vehicle thermal management system comprises an SOFC heat-insulating water tank arranged outside an SOFC hot box, and a first cooling line and a second cooling line both connected between a water inlet pipe and a water outlet pipe of the SOFC heat-insulating water tank. A first on-off valve, a first water pump, and a first heat exchanger used for cooling a high-voltage battery are arranged on the first cooling line, a first temperature sensor is arranged on the SOFC heat-insulating water tank, and a second temperature sensor is arranged on the high-voltage battery; a second on-off valve, a second water pump, and a second heat exchanger used for cooling a motor are arranged on the second cooling line, and a third temperature sensor is arranged on the motor. By means of the SOFC heat-insulating water tank, the vehicle thermal management system can not only use the heat energy of the SOFC hot box to assist the cold start of the vehicle, but also recover the heat energy generated by the motor and use the heat energy to maintain the temperature of the SOFC hot box, thereby significantly increasing the energy utilization rate of the vehicle.
