3. European standard DC charging socket outline drawing and low voltage wiring

4. Temperature sensor in socket

Temperature sensor model: PT1000, the temperature sensor model can be adjusted according to customer needs

Suggested temperature control: when the temperature reaches 100°C, the current limiting process is performed, and the charging is stopped when the temperature reaches 120°C.

Reason for requirement: IEC62196 stipulates that the charging product is used at a temperature of -30°C to +50°C, and the terminal temperature rises at a maximum of 50K. When the temperature reaches 100°C, the current should be limited to prevent the temperature from rising continuously. 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.

Allowable working current: 0.3mA max.

The electronic lock is driven by a motor, uses a micro switch as a position signal feedback device, and is connected to an external control circuit through PIN1, PIN2, PIN3, and PIN4 to achieve electronic lock locking, unlocking and signal feedback.
