New energy vehicle power battery temperature sensor

　　NTC temperature sensors are widely used in new energy vehicle power battery systems. Generally, thermistors with resistance value of R25-10K and B value of 3435 are selected. "Emission reduction" is one of the main directions of global industrial development. On the one hand, it refers to the need to continue to develop "energy saving and emission reduction" technologies for internal combustion engines, and on the other hand, it refers to the need to strengthen the development of new energy vehicles.

　　Among them, the new hybrid / pure electric vehicle is the main direction. The new electric vehicle is a hybrid design that is mainly driven by electric motors and driven by gasoline/diesel. The sensors used mainly include sensors for detecting battery temperature, temperature sensors for monitoring motors, and thermistor temperature sensors for battery cooling systems.

　　Minchuang Electronics is an early professional manufacturer of NTC thermistors in China. The NTC thermistors produced by the company are widely used in various temperature measurement and temperature compensation occasions.

　　The function of the temperature sensor is to measure the temperature of the engine's intake air, cooling water, fuel, etc., and convert the measurement results into electrical signals and send them to the ECU. For all gasoline electronic control systems, intake air temperature and cooling water temperature are two temperature parameters necessary for ECU control, while other temperature parameters vary with the type of electronic control system and control needs.

　　The intake air temperature sensor is usually installed in the air flow meter or the intake port or air flow meter from the air filter to the throttle body, and the water temperature sensor is arranged in the appropriate position on the engine cooling water circuit, the cylinder head or the body . There are many types of sensors that can be used to measure temperature, such as wire wound resistance type, diffusion resistance type, semiconductor transistor type, metal core type, thermocouple type and semiconductor thermistor type. The most widely used is the thermistor temperature sensor.
