Signal processing: The controller receives signals from the charging gun and the vehicle, such as connection confirmation signals, vehicle unlock/lock status signals, etc., and determines whether to lock or unlock operations according to these signals.

Logical judgment: The logic circuit inside the controller makes a logical judgment according to the received signal to determine whether the electronic lock needs to be locked or unlocked. For example, when charging is complete and the vehicle is unlocked, the controller sends an unlock signal.

PWM signal control: The controller uses PWM (pulse width modulation) signal to control the driver circuit of the electronic lock, and realizes the locking and unlocking of the electronic lock by adjusting the level of the PWM signal. When the PWM signal levels are complementary, the electronic lock will lock or unlock according to the high and low level pulses of the signal.

Temperature monitoring: The controller may also include a temperature detection module to detect the temperature of the positive and negative poles of the charging gun. When the temperature exceeds a set threshold, the controller will cut off the charging power to ensure safety.

Dual unlock mechanism: In some cases, the controller will output an unlock pulse when the system power is powered and the vehicle controller ends the active opening, and then output the unlock control signal again after the set time to ensure the reliable unlock of the electronic lock.


In summary, the controller of the electronic locking mechanism of the DC charging gun head ensures the safety and reliability of the charging process by precisely controlling the state of the electronic lock, and provides the convenience of user operation.
