BATTERY MODULE CHARGING SYSTEM

摘要

A battery module charging system of the present invention is provided with: a power transmission apparatus (60) that comprises a primary coil (6) for transmitting AC power; a power reception unit (70, 8) that comprises a secondary coil (7) for receiving the AC power transmitted from the primary coil, and converts the received AC power into DC power; positioning mechanisms (60a, 70a) configured so that the power transmission apparatus is positioned so as to be attachable/detachable to/from the power reception unit, and positioned so that inductive coupling between the primary coil and the secondary coil is possible when the transmission apparatus is positioned; and selection circuits (21, 25, 29) configured so as to be able to charge, selectively, DC power to a plurality of cells of a battery module (B), which is composed by having the plurality of cells, each of which are rechargeable batteries, connected in series.
