Function of PTC electric vehicle heater

The function of PTC electric vehicle heater is to generate heat after the resistance is electrified, and work through the blower to make the air pass through this element to achieve the effect of heating the air. It is generally installed at the location of the heating water tank of traditional fuel vehicles. PTC electric vehicle heater has the characteristics of energy saving, constant temperature, safety and long service life due to its resistance value increasing or decreasing with the change of ambient temperature.
1. It is an electric vehicle heater on electric vehicles, and is a ceramic heater.
2. Since electric vehicles, electric vehicle heaters have been mostly used. The heater heats the circulating water, and the heater directly heats the air. Later, we learned that the air heater should be enlarged or abandoned, point to point heating and face to face heating.

3. The electric vehicle heater has good performance, very small volume, high space utilization rate and good heating effect. With PTC heating technology, PTC has good characteristics of self-temperature, self-constant temperature and self-saving energy.
4. PTC electric vehicle heater has the advantages of constant temperature heating, long natural life, energy saving, no open flame, good safety performance, easy control of heat generation, etc.
5. The product is mainly applicable to auxiliary PTC heaters such as new energy electric vehicle air conditioners, automobile air conditioners, household air conditioners, air conditioners, heaters, clothes dryers, dehumidifiers, humidifiers, water purifiers, foot baths, etc.
PTC electric vehicle heater for automobile air conditioner is a heating device used for heating the cab of new energy vehicles in winter, defrosting and demisting the windshield, and heating the battery pack. The principle of heating is that the current flows through PTC elements to generate heat. At low temperature, it will flow through excessive current and generate a large amount of heat. As the calorific value increases, the resistance value will increase and the current will be limited. With these characteristics, air and water can be heated and circulated, thus becoming the heat source of heating.
With the popularization of new energy electric vehicles, the electrification technology of PTC electric vehicle heater management system has also developed rapidly. In thermal management, PTC electric vehicle heater scheme is generally adopted for heating elements, that is, PTC semiconductor ceramic elements are used to heat air or circulating water to achieve the purpose of electric vehicle defrosting, air conditioning and battery pack insulation. PTC electric vehicle heater uses high-voltage power battery as power supply, and the power battery pack shall provide power for heating. Therefore, it is very important to monitor the current of the PTC heater connected to the battery pack, which is crucial for the stable operation and energy saving and consumption reduction of the high-voltage battery pack.
