    Publish time 2021-08-26 14:21    

High Voltage PTC air heater for elecrtric vehicle.

With focus on environmental protection, electric vehicle development has gained tremendous international attention and are getting into automotive market. Automobiles with internal combustion engines use engine waste heat for heating., they need additional equipment as their main heating source. High Voltage Positive Temperature Coefficient (PTC) Heaters which are capable of achieving the required heating power, efficiency, and reliability is considered to be best choice.
