PTC heating

The PTC on electric vehicles refers to the thermistor, which is a temperature-sensitive semiconductor resistor that generates heat when current passes through it, and its resistance value increases as the temperature increases.

Electric vehicle heating systems mostly use PTC to heat air or PTC to heat cooling water.

PTC water heater structural principle

When heating, the PTC heater first heats the cooling water, and then uses the cooling water to heat the fresh air pumped in from the air inlet. The air is indirectly heated, and the relatively high-temperature air enters the interior of the vehicle from different air inlets controlled by the control valve. The temperature inside the car increases to realize the heating function in the car.
