The invention discloses an integrated thermal management system and a vehicle. The integrated thermal management system includes a passenger compartment temperature regulation subsystem, a battery temperature regulation subsystem, a first temperature sensor, a second temperature sensor and a thermal management controller. The regulating subsystem includes a direct cooling plate of the battery pack and an intermediate heat exchanger, and a second electronic expansion valve is arranged on the pipeline between the second interface of the direct cooling plate of the battery pack and the second interface of the intermediate heat exchanger; the first temperature sensor The second temperature sensor is used to collect the temperature of the passenger compartment; the thermal management controller is configured to control the temperature regulation subsystem of the passenger compartment and the temperature regulation subsystem of the battery according to the temperature of the battery and the temperature of the passenger compartment. The system and vehicle of the present invention have low cost and low energy consumption, and can rationally utilize the energy of the whole vehicle.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to an integrated heat management system and a vehicle using the integrated heat management system. Background technique [0002] In the related art, for the thermal management system of the vehicle, when cooling or heating the battery pack of the vehicle, the temperature of the refrigerant delivered to the battery pack is overheated or overcooled or the temperature is uneven, causing damage to the battery and affecting the battery life. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide an integrated thermal management system. When the system heats or cools the battery, the refrigerant delivered to the battery pack is more uniform, so as to protect the battery and prolong the battery life. [0004] A second object of the invention i...
