The electric car heater with PTC element

Application

Features

Parameter

The product used in pure electric cars and hybrid vehicles in heating or defrost using PTC heater

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 ceramics as a heating element is applied in electric vehicle defrosting or heating, the most basic requirement is for a long time in the reliability of high voltage, new electronic production of this kind of PTC ceramics has the following features:

1 high voltage resistance, high resistance to voltage can reach more than 1300 VDC, ensure the reliability of the heater is 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 under the high dc voltage power aging, after long-term use can still maintain good heating effect;

4 Curie temperature can be adjusted according to customer's request, in the range 140-250 degrees;

5 life for more than 10 years
