PTC heater for new energy vehicles heats air conditioners and batteries at low temperatures. Its core materials can automatically control temperature, prevent overheating, and ensure driving safety. Through rigorous testing to verify heating speed, pressure resistance and extreme environmental stability, Younai Testing escorts product quality with international standards to ensure efficient operation of batteries and extend life.
Function and structure of HV PTC heater
New energy pure electric vehicles cannot use the remaining heat to heat the warm air conditioner because they have no engine. In low temperature environments, in order to ensure the normal operation of the battery pack and increase the cruising range, new energy vehicles are specially equipped with high voltage PTC heater. The heater not only provides heat source for the air conditioning system in the car, but also is responsible for injecting heat into the battery heating system. Its overall structure includes radiator (containing PTC heating pack), coolant flow channel, main control board, high-voltage connector, low-voltage connector and upper shell and other components, which together constitute an important part of the thermal management system of new energy vehicles.
Function of HVCH in the car
The PTC heater used in new energy vehicles is an innovative automotive heating device, and its core component is PTC (positive temperature coefficient) material. This material is unique and can self-regulate temperature. When the temperature gradually rises, its resistance value will also increase accordingly, thereby limiting the passage of current, ensuring safe use and preventing overheating.
Unique performance of PTC materials
PTC electric heater can quickly heat the air inside the car without starting the engine, which not only improves the comfort inside the car, but also helps save energy and reduce the impact on the environment. Given that the batteries of new energy vehicles will have problems of shortened life and reduced performance in low temperature environments, PTC heaters have become an indispensable heating device in such vehicles.
The role of positive temperature coefficient PTC heaters on batteries
The core function of the PTC heater equipped in the battery pack is to generate heat when the battery temperature is too low, thereby gradually heating the battery to a suitable operating temperature range. This function not only helps to reduce the internal resistance of the battery, thereby increasing the output power of the battery, but also effectively extends the service life of the battery. In addition, by accurately controlling the heating power of the PTC heater, it is possible to ensure that the battery temperature is maintained at an appropriate level, thereby avoiding potential damage caused by overheating or overcooling of the battery.
