Working principle of electric defroster for EV and its application
in air conditioning system
The electric defroster of new energy vehicles is a device that uses electric energy to heat. It is mainly used to remove frost, ice, snow or fog on the surface of automobile glass to improve driving safety. In the air conditioning system of new energy vehicles, electric defroster is widely used to ensure the clarity of glass surfaces such as windows and mirrors. Here is how it works and its application in air conditioning systems:
working principle:
Heated glass surface: Electric defroster is usually installed on the glass surface, and its main component is a resistance wire or conductive coating. When an electric current passes through a resistive wire or conductive coating, heat is generated, heating the glass surface.
Melting ice, snow or defogging: The heated glass surface quickly melts or evaporates the ice, snow or fog attached to it, thereby clearing the frost or fog on the glass surface.
Keep the driver's vision clear: By heating the glass surface with the electric defroster, the driver's vision can be kept clear and driving safety improved.
Application in air conditioning system:
The air conditioning system of new energy vehicles usually includes a defrost function, in which the electric defroster plays a key role. It is generally integrated with the vehicle's air conditioning system and controls the heating power and working time through the control unit of the air conditioning system.
Intelligent control: The work of the electric defroster can be intelligently adjusted by the vehicle's electronic control unit, which automatically controls the working mode and heating power of the electric defroster based on conditions such as temperature and humidity inside and outside the vehicle to improve energy efficiency and energy-saving performance.
Integrated air-conditioning system: The electric defroster and air-conditioning system cooperate with each other to closely integrate the defrosting function of glass surfaces such as windows and mirrors with the air-conditioning system, providing a more comprehensive and intelligent driving experience.
Temperature control: When the electric defroster is working, it will also be controlled by the temperature of the air conditioning system. According to the set temperature of the air conditioning system and the needs of the user, it automatically adjusts the heating power and working time to ensure the defrosting effect on the glass surface and the comfort of the driver. Spend.
In summary, the application of new energy vehicle electric defroster in air conditioning systems can effectively improve the driver's driving safety and driving comfort, especially in severe weather and climate conditions.
