Abstract

The invention discloses an electric vehicle thermal management system, comprising a passenger compartment thermal management module and a power system thermal management module. The passenger compartment thermal management module comprises an electric compressor, a condenser, a condensing fan, an expansion valve, an HVAC system, a first water pump, a water PTC heater and a connection pipeline. The power system thermal management module comprises a power battery pack, a water bottle, a second water pump, a radiator, a radiator fan, a third water pump, a controller, an inverter, a motor, a thermoelectric plate heat exchanger and a connection pipeline. The power system thermal management module is realized by adopting the thermoelectric plate heat exchanger. The thermoelectric plate heat exchanger has heating and cooling functions based on the Peltier effect. The electric vehicle thermal management system has the characteristics of simple structure, good reliability, precise temperature control, high heat utilization efficiency, and capability of effectively improving the battery using efficiency of the electric vehicle and extending the mileage of the electric vehicle.

Description

technical field [0001] The present invention relates to the fields of electric vehicle technology and thermoelectric technology, in particular to an electric vehicle heat sink with simple structure, good reliability, precise temperature control and high heat utilization rate, which can effectively improve the use efficiency of electric vehicle batteries and prolong the mileage of electric vehicles. management system. Background technique [0002] At present, electric vehicles, as a new energy vehicle with reduced oil consumption, low pollution and low noise, are considered to be an important way to solve the energy crisis and environmental degradation. Like traditional internal combustion engine vehicles, electric vehicles also require thermal management, mainly including thermal management of the passenger compartment and thermal management of the power system. In the existing electric vehicle thermal management method, the passenger cabin is cooled by air conditioning, an...
