PTC High Voltage Heater For CE
The future of mobility is electric. Renewable energy sources allow for carbon-reduced mobility. Anew generation of vehicles is emerging--E-cars and hybrid.
Increased electric vehicle rang results in less engine heat and thus to higher heating requirements.
The 7kw high voltage coolant heater is mainly used for heating the passenger compartment ,defrosting and removing fog on the window,or preheating battery thermal management system battery ,to meet the corresponding regulations, functional requirements.
Description
PTC High Voltage Heater for CE
Products Description
Among the existing electric heater concepts for automobiles, the most popular is the PTC heater using a resistor made of barium titanate (BaTiO3) with a positive temperature coefficient. To this end, several details of its operating principle are described and compared with layered heaters developed as high-voltage heaters HVH.
