PROBLEM TO BE SOLVED: To enable a full charge to a plurality of batteries in a short time, a full and rapid charge to all of batteries without lowering the battery performance of a plurality of batteries, and a full charge to a plurality of batteries in a short time using a charging wire that is manufactured at a low cost. SOLUTION: In the method for charging a plurality of batteries, a battery charged with the charging wire is switched to a time division, and a plurality of batteries are fully charged by a pulse charge and, when a charge to a full- charged battery is ceased, the charge is re-started to the next battery advancing the charge timing.
