How it works
A high-voltage power supply usually powers electric vehicles high-voltage electric defrosters to drive the heating element to generate heat and use the heat to remove frost, fog, and other substances on the car windshield. Its working principle can be mainly divided into the following steps:
High-voltage power input
Electric vehicles are powered by high-voltage batteries (usually battery systems between 350V and 800V). The electric high-voltage defroster converts high-voltage electrical energy into the energy required for heating through a controller.
How it works
Heating by the electric heating element
After receiving electrical energy, the electric defroster's built-in heating element (usually a heating wire or a PTC heater) quickly heats to a high temperature. The PTC heater has the characteristic of self-regulating temperature. When the temperature is too high, its resistance increases, automatically reducing power output to prevent overheating.
Heat conduction to the glass surface
The heat generated by the heating element is transferred to the glass surface by heat conduction, so that the temperature of the glass surface increases, and the frost or fog is quickly evaporated or melted.
Quickly remove frost and fog
By heating the glass, the accumulated water vapor of frost, fog, etc. is removed, the clarity of vision is restored, and the driver's safe driving is ensured.

Product technical introduction
Combination of high-voltage power supply and low-voltage control:
A high-voltage power supply (such as 600V) is used to provide sufficient power for the heating element, and the defroster is precisely controlled through a low-voltage control circuit (such as 24V).
Thermostatic switch and delay circuit:
Equipped with a temperature-controlled switch, it automatically cuts off the power when the temperature of the heating element is too high to prevent overheating damage; the delay circuit allows the fan to continue to run for a period of time after the defroster is turned off to dissipate the internal residual heat.
Multiple working modes:
Different working modes are designed according to the ambient temperature and actual needs. For example, the cooling fan can be turned on directly in a high-temperature environment, while the air needs to be heated before turning on the fan in a low-temperature environment
Products application
Defrosting the front windshield: The high-voltage electric defroster generates heat through the heating element to melt the frost on the windshield, ensuring a clear view for the driver.
Defrosting the outdoor heat exchanger: In the heat pump air conditioning system, the outdoor heat exchanger is prone to frost, which affects the heating effect. The high-voltage electric defroster can quickly remove the frost on the heat exchanger to ensure the normal operation of the air conditioning system.

Products FAQ
FAQ
Q: How to ensure the safety of high-voltage electric defrosters?
A:
High and low voltage partition power supply: The high-voltage power supply is combined with low-voltage control to separate the high-voltage area and the low-voltage area, effectively ensuring electrical safety isolation.
Multiple safety protection circuits: Multiple safety protection circuits and mechanisms are designed, such as normally open temperature control switches, normally closed temperature control switches, etc.
When the temperature is too high, the temperature control switch will automatically cut off the power to prevent overheating damage. Alarm system: If the circuit fails and the temperature rises abnormally, the buzzer will sound an alarm to remind the driver to take measures such as powering off and maintenance.
Q: Will the use of high-voltage electric defrosters increase the energy consumption of the vehicle?
A:
Intelligent working mode: A variety of working modes are designed according to different ambient temperatures. In a high-temperature environment, there is no need to heat, and the cooling fan can be turned on directly to defrost; in a low-temperature environment, the defroster air must be heated to a certain temperature before turning on the fan to reduce energy consumption.
Heat pump system optimization: Using a heat pump system for defrosting, compared with traditional PTC electric heaters, the heat pump system can save 59% of power consumption in heating mode and 67% of power consumption in dehumidification mode.
PTC electric heater with adjustable power: Using a PTC electric heater with adjustable output power, it works at low power while meeting the driver's operating requirements, effectively reducing the power consumption of the electric defroster. Turning off the fan to reduce heat exchange loss: During the defrosting process, turning off the outdoor heat exchanger fan can reduce the heat exchange loss on the air side and improve the defrosting efficiency.
