Description

technical field

[0001] The invention relates to the technical field of electric vehicle heating, in particular to an electric vehicle floor heating system. Background technique

[0002] Use PTC thermistor type heating system for heat generation and heat pump system for heating. The current heat pump heating and PTC heating both rely on the air supply system, using the air supply system to blow hot air to the cockpit and passenger compartment, and heat the cabin through the thermal convection of the warm air in the car. However, this warm air heating method consumes a lot of power and has a low thermal energy utilization rate, which has a great impact on the cruising range of the electric vehicle. For example: the efficiency of the heat pump heating electric vehicle motor can reach 90%, and the remaining 10% of waste heat is not enough for cabin heating; Vehicle mileage. At the same time, since the heating of the air conditioner directly blows out hot air through mechanica...
