Product Details
New-energy light trucks, light passenger vehicles, and other new-energy commercial vehicles primarily rely on high-voltage electricity as their power source. Without the residual heat from traditional vehicle engines, the cabin’s heating needs must now be met entirely by converting high-voltage electricity into thermal energy. The PTC liquid electric heater serves as the device that supplies this essential heat to the entire vehicle. It transforms high-voltage electricity into usable thermal energy, which is then transferred to a heat-transfer medium via an efficient heat exchanger. This medium carries the thermal energy to the specific areas of the vehicle that require it, enabling comprehensive thermal management for optimal performance.
The EW6 PTC electric heater leverages core PTC electric heating technology, making it ideal for compact heating spaces in new-energy light trucks, light passenger vehicles, and other similarly sized new-energy electric cars. It can also be seamlessly integrated into diversified battery thermal management systems, such as those used in energy storage and hydrogen fuel cell applications.
The EW6 PTC electric heater features high-voltage electric liquid heating technology, precisely addressing the need for efficient heating and warmth in the compact spaces of new-energy vehicles, as well as maintaining optimal temperatures for battery pack heating and insulation. It provides a stable and reliable PTC-based all-electric heating solution tailored for battery thermal management in new-energy vehicles, energy storage systems, and hydrogen fuel cell applications.

PTC Electric Heater Operating Principle ▶
The EW6 PTC electric heater operates by using a controller to regulate the amount of heat generated by the PTC element. This heat is then transferred to the antifreeze solution via a heat exchanger, ultimately raising the temperature of the antifreeze.
The PTC core of the EW6 PTC electric heater is a positive temperature coefficient resistor that generates heat when powered on. Once the temperature reaches the Curie point (the stable temperature achieved when voltage is applied to the PTC), it remains constant, ensuring both safety and reliability. The PTC core is arranged in a cross configuration with the water channels of the heat exchanger, allowing the heat generated by the PTC core to be efficiently transferred via these channels to the internal antifreeze fluid, thereby raising the fluid's temperature.
The controller of the EW6 PTC electric heater primarily functions to regulate the power output of the PTC heating element, controlling the amount of heat generated. It also establishes communication with the vehicle, receiving operational commands and requirements from the vehicle, while simultaneously monitoring and providing real-time feedback on the heater's running status.
PTC Electric Heater Operating Procedure ▶
After receiving the vehicle's operational command and temperature requirements, the EW6 PTC electric heater determines whether heating is needed based on the difference between the desired temperature and the current water temperature, then activates the PTC control system accordingly. Throughout the process, the heater continuously monitors whether the actual water temperature has reached the target level. Once the target temperature is achieved, the heater automatically reduces its power output or ceases heating altogether.
