The Application of NTC thermistor in the Automotive Industry

With the continuous development of the automotive industry, intelligence and electrification have become the industry trends. NTC thermistor, due to their high sensitivity, precise temperature measurement, and rapid response, play a crucial role in multiple automotive applications such as new energy vehicles, battery management systems (BMS), engine temperature monitoring, and air conditioning systems.


Core Applications of NTC thermistorin Automobiles
Battery Management System (BMS)
In new energy vehicles, the performance and safety of batteries directly determine the vehicle’s range and stability. NTC thermistors are used for battery temperature monitoring to ensure that the battery pack operates within an appropriate temperature range, preventing overheating or overcooling, improving charging and discharging efficiency, and extending battery life.

Temperature Monitoring of Motors and Inverters
In electric vehicles, the drive motors and inverters generate a large amount of heat during high-load operation. NTC thermistors can monitor the temperature of motor windings and inverters in real time. When the temperature approaches a dangerous threshold, the system will automatically adjust the operating state or activate the cooling system to prevent overheating damage.

Automotive Air Conditioning System
NTC thermistors are widely used in the temperature sensing modules of automotive air conditioning systems to detect the temperature inside and outside the vehicle, evaporator temperature, and coolant temperature, ensuring that the air conditioning system intelligently adjusts according to the ambient temperature, enhancing comfort and optimizing energy consumption.

Engine and Cooling System
In fuel vehicles, the operating temperature of the engine is crucial for performance. NTC thermistors are used to monitor coolant temperature, intake air temperature, and exhaust temperature, ensuring that the engine operates at the optimal temperature and preventing faults caused by overheating or abnormal temperatures.

Tire Pressure Monitoring System (TPMS)
Tire temperature is closely related to tire pressure, and high temperatures can increase the risk of tire blowouts. NTC thermistors are used in TPMS systems to monitor tire temperature, combined with tire pressure data, to provide real-time warnings and enhance driving safety.

Seat Heating and Advanced Driver Assistance Systems (ADAS)
In intelligent cabins, NTC thermistors are used in seat heating systems to precisely control seat temperature, providing a more comfortable driving experience. They are also applied in the sensor modules of ADAS to ensure that radar, cameras, and other devices operate at appropriate temperatures.
