Technical points and solutions for temperature sensors for charging guns/piles

Charging pile is one of the key equipments for EV charging, and temperature sensor plays an important role in charging pile. Here are some technical points about the use of temperature sensors in charging guns/piles:

1、PURPOSE AND FUNCTION: The temperature sensor is used to monitor the temperature of the charging pile itself and the battery of the electric vehicle. Its main purpose is to keep the temperature of the charging pile and the battery within a safe range and to provide the necessary information to determine the charging power and the control strategy of the charging process.

2、Temperature Sensor Type: Commonly used temperature sensors for charging piles include thermocouples, thermistor and infrared temperature sensors. Choosing the right sensor depends on application needs and performance requirements.

3、Installation location: The temperature sensor can be installed in key parts inside the charging pile, such as the charging power supply, charging lines, battery connectors, etc., in order to monitor the temperature of these parts in real time. In addition, the sensor can also be installed on the EV battery to monitor the temperature of the battery in real time.

4、Data Acquisition and Processing: The temperature sensor transmits temperature data to the control system for real-time acquisition and processing by connecting with the control system of the charging pile. The control system can calculate the algorithm according to the temperature data and decide measures such as charging power adjustment, temperature alarm or automatic charging stop.

5、Temperature Management Strategies: Based on the data from the temperature sensors, the charging pile can implement temperature management strategies, such as dynamically adjusting the charging power, reducing the charging rate or stopping charging when the temperature rises. These strategies help protect the charging post and battery, extend their service life, and ensure the safety and reliability of the charging process.
