技术领域technical field

The large amount of electricity will seriously affect the cruising range of electric vehicles; although the existing heat pump air conditioning system uses three heat exchangers for heating, but there is no air supply and enthalpy increase circuit, resulting in the heat pump air conditioning system in the low temperature environment. The problem of frosting on the heat exchanger affects the heat exchange performance and low temperature heating performance of the heat pump air conditioning system; the existing technology does not control the battery temperature, however, the temperature has a great impact on the battery performance, including the resistance of the battery, charging and discharging Performance, safety, life, etc.; if the temperature is too low, it will affect the power and energy output of the battery, and it cannot meet the power requirements of the cold start of electric vehicles. Too high temperature will shorten the battery life and reduce the safety.
