With the awareness of environmental protection and the continuous development of technology, we witness a remarkable global surge in EVs, with adoption rates climbing steadily. NTC thermistor is one of the core components of EV; it protects the performance and reliability of the drive motor.
Functions of NTC thermistors for drive motor:
1.Temperature monitoring and protection: The drive motor generates a lot of heat during operation. Overheating can cause motor damage, such as fire and other safety hazards. NTC thermistors can monitor the drive motor’s temperature changes in real-time and provide feedback on the data to the control system. Real-time reactions can be taken to dissipate heat or reduce power output to protect the motor’s safe operation.
2. Efficiency optimization: With accurate temperature information provided by NTC thermistors, the control system can adjust the motor’s working state according to temperature changes and optimize energy efficiency. For example, at a low temperature, the thermistor can sense the motor’s low temperature, and the control system will preheat the motor in advance using PTC heating to improve starting efficiency and working stability.
3. Fault diagnosis: NTC thermistors can monitor abnormal temperature changes in the motor. When the motor is overheated, the thermistor sends an alarm signal to the control system and indicates possible faults. This helps to detect and eliminate motor faults in a timely manner and improves the vehicle’s reliability and safety.
Advantages of NTC thermistor:
1. High precision: A thermistor with high accuracy and stability can provide accurate temperature data and reliable information for the control system.
2. Fast response: A thermistor with a fast response can sense the real-time temperature so that the control system can make corresponding adjustments in time.
3. Small size and volume: The thermistor is small and tiny, highly adaptable, and easy to install on the drive motor’s heat dissipation components.
NTC thermistors play an important role in the drive motors of EVs. They can detect the motors’ temperature changes in real-time and provide accurate temperature data for the control system.
Through temperature monitoring and protection, efficiency optimization, and fault diagnosis, thermistors can ensure the safe operation of the drive motors and improve the energy efficiency and reliability of the entire vehicle.
With the rapid development of the EV market, the application prospects of NTC thermistors will be wider, which is of great significance to promoting the development of EV technology.
