In recent years, my country's automobile and its related industries have developed rapidly. In 2020, my country's automobile output has reached 67.27 million, becoming the world's third largest automobile manufacturing country. my country's well -developing automobile market has attracted most international automotive component giants to come to China to invest in factories or establish a sales network. With the consensus of low -carbon environmental protection, through policy guidance and promotion of emerging industries, it is a common practice of governments in various countries. The strategic significance of the development of electric vehicles to relieve energy and environmental pressure and cultivate new economic growth points is increasingly prominent, and countries have spared no effort to promote the development of the electric vehicle industry. In 2015, my country surpassed the United States to become the world's largest electric vehicle production and sales country. From the perspective of market share, number of enterprises and supporting industries, the characteristics of my country's electric vehicle industry entering the development period from the introduction period. Essence
 
With the rapid development of automotive electronics, the number of sensors used on cars is also increasing. At present, ordinary cars are used dozens of sensors, and more than 200 sensors are used in high -end cars. The number and types of sensors have become important indicators to measure the performance and grade of modern vehicles.

Multi -categories provide important data for car performance and safety. Monitoring engines and transmission systems such as oxygen, fluid, temperature, voltage, current, etc.

The temperature control of the air -conditioning on the electric car, monitor the temperature of the engine coolant, the central door lock device, the top of the sediment, the seat adjustment of the soft facility, the windshield water scraper and other components all use the thermistor sensor.

Velian PT200 thermistor temperature sensor is the characteristics of seismic, high accuracy, and fast response.
