Temperature Sensor

NTC10K temperature monitoring principle:

2 temperature sensors within the DC+ and DC- terminals

Temperature sensor model: NTC R25℃=10KΩ±1%, curve coefficient B25℃/50℃=3950, allowable operating current: 2mA max.

According to the provisions of Article 9.1 of GB/T 18487.1-2015, when the charging current is >16A, the power supply socket and the vehicle socket should be equipped with a temperature monitoring device. Temperature sensors are arranged in the DC+ and DC- holes of the charging socket, and there are two temperature sensors in the DC charging socket. Customers can formulate charging strategies based on temperature feedback.

Suggested temperature control: When the temperature reaches 100°C, limit the current, and stop charging when the temperature reaches 120°C.

Reason for the requirement: GB/T20234 stipulates that the operating temperature of charging products is -30°C~+50°C, the maximum temperature rise of the terminals is 50°C, and the current should be limited when the temperature reaches 100°C to avoid continuous temperature rise. In order to avoid the aging of the internal parts and cables of the charging product under high temperature conditions, the charger should stop charging when the temperature reaches 120°C.
