10kw High Voltage Vehicle Heater

The heating principle of the PTC thermistor heating system is relatively simple and easy to understand. It is similar to the resistance wire heating system in that it relies on current to pass through the resistor to generate heat. The only difference is the material of the resistor. The resistance wire is made of ordinary high-resistance metal wire, while the PTC used in pure electric vehicles is a semiconductor thermistor. PTC is the abbreviation of Positive Temperature Coefficient. Its characteristics are that as the temperature increases, the PTC material The resistance will also increase. This characteristic determines that under constant voltage conditions, the PTC heater heats faster when the temperature is low. When the temperature rises, the resistance becomes larger, the current becomes smaller, and the PTC consumes less energy, so that it can Keeping the temperature relatively constant will also save electricity compared to pure resistance wire heating.
