Problems solved by technology
When an electric vehicle with this circuit is charging, the power supply of the electric vehicle is still connected to the electric door lock switch on the electric vehicle. , the electric vehicle may be started, which will bring safety hazards to the charger and the electric vehicle
In addition, after the charging is completed, the power supply of the electric vehicle is still connected to the solar panel. When the vehicle is idle, the solar panel always outputs a high voltage (greater than the safe voltage). In the case of accidental touch, it will cause electric shock and short circuit Vehicle Spontaneous Combustion Accident
