The portable charging cable is mainly composed of a charging gun head, a high-voltage charging cable, a cable control box, and a 220V three-phase plug.
The AC charging port of new energy vehicles is a 7-hole structure, most of the charging guns are mechanical locks and electronic locks, press the mechanical lock button of the gun head, the mechanical lock will be lifted, after the gun head is inserted into place, release the mechanical lock button, the mechanical lock of the gun head will be stuck into the mechanical lock slot of the charging port on the car to ensure that the charging gun will not fall off. After closing the car door (locking the car) with the car key, the electronic lock of the charging gun will be activated, and the electronic lock pin controlled by the electromagnetic switch stretches outward, inserts the electronic lock hole, and is against the top of the mechanical lock, so that the mechanical lock cannot be pulled out of the mechanical lock slot, and the charging gun cannot be pulled out of the charging port at this time. After pressing the unlock key of the car key, the electronic lock lock pin exits the lock hole, and at this time, the mechanical lock key can be pressed to exit from the lock slot and pull out the charging gun. Therefore, the existence of electronic locks is to prevent the charging gun from being maliciously pulled out during the charging process, but vehicles without charging gun electronic locks do not have this function.
