Floor type heating system of electric automobile

Abstract

The invention provides a floor type heating system of an electric automobile. The system comprises a plurality of floor type heating assemblies, and the floor type heating assemblies are installed on a floor of an electric automobile; each floor type heating assembly comprises a bottom plate, an infrared reflecting film layer, a heating film layer and an electrode; the bottom plate can be placed on the floor of the electric automobile; an infrared reflecting film layer is arranged on the upper surface of the bottom plate and is used for reflecting infrared light; and a heating film layer is arranged on the upper surface of the infrared reflecting film layer, electrodes are arranged on the surface of the heating film layer, and any electrode is directly communicated with a power supply of the electric vehicle or is communicated with the power supply of the electric vehicle after being connected in parallel with electrodes of adjacent floor type heating assemblies. The electric vehicle is comfortable, healthy, energy-saving and environment-friendly, the floor block can serve as a heating unit, the heating temperature, the heating time and the heating position can be selected according to needs of passengers, electric energy consumption of the electric vehicle can be greatly reduced, the endurance mileage is increased, and the heating problem of the electric vehicle in winter can be effectively solved.

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...

Problems solved by technology

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 electric vehicles.

For example: the efficiency of the heat pump heating electric vehicle motor can reach 90%, and the remaining 10% of the waste heat is not enough for cabin heating; PTC heating needs to consume a large amount of electric energy from the electric vehicle battery to heat the resistance wire, which will greatly reduce electric car mileage

At the same time, since the heating of the air conditioner directly blows out hot air through mechanical power, the passengers and the driver will obviously feel the wind when using it, which will affect the car experience of the passengers and the driver, and the heating of the warm air will make the interior of the car The air becomes drier, which is not good for human skin and health
