摘要

The present invention relates to a group of charge-storage units, a charger, an electronic device, an electrically driven vehicle, a method for charging and a method for discharging the group of charge-storage units, a method for supplying/receiving electric power, and a method for determining the charging/discharging route in the group of charge-storage units capable of providing a method for charging a group of charge-storage units composed of a plurality of charge-storage units connected together as desired. The method for charging a group of charge-storage units is a method for charging a secondary battery cell in a group of charge-storage units configured so that a plurality of charge-storage units (11) having secondary battery cells is connected in the shape of a straight line or a mesh, wherein the method comprises a charging step in which, when full charging is achieved in a secondary battery cell that constitutes a single charge-storage unit and is connected upstream of the charge-storage units to a power source (12) for charging the charge-storage units, charging of the single charge-storage unit in question is stopped and a charge-storage unit connected further downstream of the single charge-storage unit in question is charged via the single charge-storage unit in question.
