Abstract:
1. A classified solar charging method using a solar cell to charge multiple rechargeable batteries, comprising steps of: a variable-defining step defining four magnitude classes for each of three variables associated with a power production of the solar cell, a capacity of each rechargeable battery and a charging current of the solar cell, the four magnitude classes of the power production of the solar cell defined as strong, moderate, weak and very weak; a charging rule establishing step setting up multiple charging modes, each of which determines a value of the charging current in accordance with the corresponding magnitude class for the power production of the solar cell and the corresponding magnitude class for the capacity of each rechargeable battery; detecting the present power production of the solar cell to determine one of the magnitude classes of the power production, wherein when the magnitude class is determined to be strong, the solar cell charges all rechargeable batteries; when the magnitude class is determined to be moderate, the solar cell charges the rechargeable batteries not having a highest capacity; when the magnitude class is determined to be weak, the solar cell charges the rechargeable batteries having a lowest capacity; when the magnitude class is determined to be very weak, charge all the rechargeable batteries with the AC mains.
