Disconnecting the battery cable is the most practical method for ordinary electric vehicle users. The specific operation mode is as follows: the user first opens the base of the electric vehicle to find the battery pack, then disconnects the connecting wire between two small batteries with a screwdriver, and then opens the door lock of the electric vehicle, and the user will find that the electric vehicle has no return voltage.
As long as this operation is completed, even if the electric car is left for half a year, the battery will not be damaged due to any power loss, and there will be no vulcanization. If users need to use the electric car again, they can tighten the direct cable, and then it can return to normal.
