AI Technical Summary
Existing electric vehicle thermal management systems suffer from numerous components, complex piping, high costs, and excessive energy consumption. In particular, over-reliance on high-pressure water heaters or compressors in low-temperature environments leads to energy waste and compressor lifespan loss.
It employs components such as a five-way water valve, a three-way water valve, a warm air water pump, an electric water pump, a battery water pump, a heater, a one-way valve, a radiator, a water-cooled condenser, a cooler, and a battery pack. It achieves multiple operating modes through flow channel switching. Combined with an R134a or R1234yf electric scroll compressor, it automatically switches between water source heat pump and air source heat pump modes, using the waste heat from the electric drive to directly heat the passenger compartment or battery, reducing the need for compressor startup.
It achieves full-function thermal management, reduces system costs and energy consumption, extends the life of core components, is suitable for commercial vehicles with large cooling capacity, and improves waste heat utilization.
