In some embodiments, when it is detected that the charging current exceeds the set current threshold and/or the charging voltage exceeds the set voltage When the voltage threshold is exceeded, the charging path between the solar power generation unit and the electric vehicle's power battery is closed to avoid damage to the charging device.

For example, if a short circuit occurs between the receiving coil and the power battery of an electric vehicle, the current value between the solar power generation unit and the transmitting coil increases rapidly. When the charging current exceeds the set current range, local overheating may occur, thereby damaging the charger. device, it is necessary to close the charging path between the solar power generation unit and the power battery of the electric vehicle. When it is detected that the charging voltage exceeds the set voltage threshold, if the charging voltage is less than the set voltage threshold, it means that the charging device is faulty. At this time, the charging device cannot charge the power battery of the electric vehicle normally, and the solar power generation unit and the electric vehicle need to be shut down. Charging paths between power batteries for troubleshooting.

In other embodiments, when the charging current exceeds the set current threshold, the charging current can also be controlled to be within the set current threshold range by adjusting the opening of the conduction unit, which is not limited here.
