PTC Battery Cabin Heater For EV

 PTC Battery Cabin Heater for EV

 

Product Description

PTC electric heater is a kind of heater that uses PTC thermistor element as heat source. PTC thermistor is usually made of semiconductor material, its resistance changes sharply with the change of humidity, when the outside temperature drops, the resistance value of PTC decreases, and the calorific value will increase accordingly. According to the material, it can be divided into ceramic PTC thermistor and organic polymer PTC thermistor. For air conditioning auxiliary electric heaters are ceramic PTC thermistors. Because the PTC thermistor element has the change characteristic that its resistance value increases or decreases with the change of the ambient temperature, so the PTC heater has the characteristics of energy saving, constant temperature, safety and long service life.
