    Product Description

    The high voltage coolant heater is a heater designed for new energy vehicles. The high voltage coolant heater heats the entire electric vehicle and the battery. The PTC coolant heater provides heat to the cockpit of a new energy vehicle for defrosting and defogging. The electric parking heater can also heat other mechanisms of the vehicle that require temperature regulation (e.g. the battery).  This high voltage coolant heater is suitable for electric vehicles with rated power of 8kw and voltage range of 323-552v. The benefit of this electric parking heater is that it heats the cockpit to provide a warm and suitable driving environment, and heats the battery to extend its life. The high voltage coolant heater is installed in a water-cooled circulation system where the temperature of the warm air is gently controlled. The high voltage coolant heater drives an IGBT with PWM regulation to regulate the power and has a short time heat storage function. The high voltage coolant heater is environmentally friendly and energy saving.
