At the same time, three filling devices need to be installed on the vehicle production line to fill the three expansion pots with coolant at the same time, which makes the production cost of the vehicle higher, and the filling efficiency is low, and the waterway structure on the vehicle is complicated and the waterway layout is difficult. And limited, the efficiency of vehicle after-sales maintenance is low

The invention discloses a thermal management system of a vehicle and the vehicle. The thermal management system comprises a cooling loop, a constant-temperature loop, a heating loop and an expansion kettle; the cooling loop, the constant-temperature loop and the heating loop are all connected with the expansion kettle, and the expansion kettle is used for conducting liquid filling and exhausting on the cooling loop, the constant-temperature loop and the heating loop. According to the thermal management system of the vehicle, the expansion kettle is used for being connected with the cooling loop, the constant temperature loop and the heating loop, so that the cost of the vehicle can be reduced, the efficiency and the production takt of injecting the cooling liquid into the expansion kettleon a vehicle production line can be improved, and the after-sales repair and maintenance efficiency of the vehicle can be improved.
Description
technical field [0001] The present invention relates to the technical field of thermal management, and more specifically, to a thermal management system of a vehicle and the vehicle. Background technique [0002] At present, the electric vehicle thermal management system includes three circuits, namely the warm air heating circuit, the electric drive cooling circuit and the battery constant temperature circuit. These three circuits generally adopt a liquid circuit system and are independent of each other. Existing vehicles require three expansion pots as each circuit requires one expansion pot for coolant filling and venting. At the same time, three filling devices need to be installed on the vehicle production line to fill the three expansion pots with coolant at the same time, which makes the production cost of the vehicle higher, and the filling efficiency is low, and the waterway structure on the vehicle is complicated and the waterway layout is difficult. And limited,...
