Pure electric vehicles and hybrid petrol-electric car output is direct voltage, is in commonly 320 VDC to 540 VDC, the highest reaches 700 VDC - 700 VDC, PTC heater is used in the electric car windshield defrost or heating, the most basic requirement is that the reliability of the long-term work under high voltage, new electronic production of this kind of PTC heater has the following features:

1 high voltage resistance, resistance heater highest voltage can reach more than 1300 VDC, ensure the reliability of the long-term work under high voltage.

2 under the low temperature heat up quickly, even if the environment temperature reaches to 40 degrees, also can realize quick start;

3 with smaller into current and burr;

4 the unique patented design structure, has a small leakage current, ensure the safety performance of heater;

5 heater under high dc voltage power aging, after long-term use can still maintain good heating effect;

6 heater surface temperature (ventilation) can adjust according to customer requirements, in the range 140-250 degrees;

The service life of the 7 up to more than 10 years
