New energy vehicles refer to vehicles with advanced technical principles, new technologies and new structures, which use unconventional fuels as power sources and integrate advanced technologies of vehicle power control and drive. New energy vehicles include pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles and so on.
In recent years, the global new energy vehicle industry has developed rapidly. Compared with traditional fuel vehicles, the biggest difference of new energy vehicles is that they use power batteries as power drivers. The components used in automobiles are different from the general civil products, which require high reliability and can adapt to the harsh environment such as high temperature, vibration and shock.
NTC thermistor has the characteristic of changing resistance value with the change of temperature, and because thermistor components have the advantages of no loss, no lag phenomenon, it is widely used in automobile air conditioning control circuit, detection of engine cooling water temperature, motor and other equipment protection, liquid level monitoring and other aspects. And the number of NTC thermistor assembly in luxury cars has reached dozens of kinds.
Let's take a look at what aspects of the NTC thermistor used in new energy vehicles are:
1. In the aspect of temperature detection: NTC thermistor is mainly used in automobile temperature control of air conditioning, monitoring engine coolant temperature, intake temperature, exhaust temperature, fuel temperature, oil temperature, transmission oil temperature, seat and Yan, catalytic converter, block glass.
2. Automobile motor and circuit protection control: NTC thermistor is mainly used in the central door lock device, awning roof, seat adjustment soft, windshield wiper motor and so on.
3. Liquid level height monitoring: NTC thermistor is mainly used for brake fluid level monitoring, engine oil and cooling water level monitoring, fuel level monitoring, etc.

4. Heater, NTC thermistor is mainly used for heating fuel, etc.
