What Is The Use of NTC Thermistors In Electric Cars

As there are more and more cars, the fuel and exhaust emissions of cars become a big problem. Because cars use gasoline which is not a renewable energy source, and the exhaust gas emitted by cars using gasoline as fuel is harmful and will pollutes the air and damages people’s health.
New energy vehicles came into being. New energy vehicles refer to vehicles that use electricity and batteries as the power source, and have the advantages of less pollution, more energy saving and environmental protection.

Electric cars are new energy vehicles. New energy vehicles use power batteries as power drives. As the information source of the electronic control system of new energy vehicles, the sensor is a key component of the electronic control system of pure electric vehicles. It is mainly used to measure temperature and monitor the temperature to prevent excessive temperature changes from affecting the electronic system of new energy vehicles.
Commonly used temperature sensors include thermocouple sensors, thermistor sensors, platinum resistance sensors, and integrated temperature sensors. New energy vehicles use thermistor sensors. Thermistor is a kind of resistor made of semiconductor ceramic material, which is sensitive to temperature, and its resistance value changes with temperature. Due to different temperature coefficients, it is divided into positive temperature coefficient thermistor (PTC thermistor) and negative Temperature Coefficient Thermistors (NTC Thermistors).
NTC thermistor has the characteristics of accurate temperature measurement, low cost, small size and high sensitivity and is used in new energy vehicles. NTC thermistors are mainly used in automobiles for temperature control of air conditioners, heating of fuel, and monitoring of brake fluid levels.
