Description

Technical Field

[0001] This application relates to the field of vehicle thermal management technology, and more specifically, to an integrated thermal management system and vehicle. Background Technology

[0002] The technological development of thermal management systems for new energy vehicles has evolved from simple distributed thermal management of the three electrical components (battery, motor, and electronic control unit) to integrated thermal management, resulting in various systems with coupled thermal coupling. Effective integrated thermal management technology can reduce energy loss caused by temperature issues. For example, operating the battery at a suitable temperature improves its charging and discharging efficiency and reduces energy loss; cooling the motor and electronic control unit can also reduce performance degradation caused by overheating, improving overall energy utilization efficiency. Simultaneously, the thermal management system is a crucial component for ensuring vehicle safety. By monitoring and controlling the temperatures of the battery, motor, and electronic control unit, it can prevent safety accidents such as thermal runaway. The thermal management system can also work in conjunction with the vehicle's air conditioning system, utilizing heat generated by the battery or coolant to heat or cool the passenger compartment, improving passenger comfort. Integrated vehicle thermal management keeps the motor and battery within their optimal operating temperature range for maximum efficiency. Combined with heat pump air conditioning technology, this can further improve the vehicle's range.

[0003] However, in existing hybrid power thermal management systems, the engine, battery, motor, and air conditioning are basically independent. Multiple independent thermal management systems not only have numerous pipes and valves, but also cannot exchange heat with each other, and are relatively expensive.
