Abstract

The battery module charging system of the present invention includes: a power transmission device including a primary coil (6) for transmitting AC power; a secondary coil (7) for receiving AC power transmitted from the primary coil through electromagnetic induction, and a power receiving unit (70, 8) that converts the received AC power into DC power; it is configured such that the power transmitting device can be attached to and detached from the power receiving unit, and when the power transmitting device is installed, the primary side coil can be connected with the secondary side coil A positioning mechanism (60a, 70a) positioned by means of electromagnetic coupling; a selection circuit (21, 25, 29) configured to selectively charge DC power to a plurality of batteries of the battery module (B), the battery module ( B) consists of a plurality of batteries connected in series as secondary batteries.

Description

technical field [0001] The present invention relates to a charging system for a battery module in which a plurality of batteries are connected in series. Specifically, it relates to a charging system for charging a plurality of batteries constituting a battery module for each battery. Background technique [0002] A rechargeable single cell is a single secondary battery that can be reused by charging, and its chargeable voltage is generally as low as several volts or less. Therefore, when a high-voltage secondary battery is required, an assembled battery in which a plurality of cells are connected in series is used. In addition, a single battery is sometimes called a unit cell or a battery (cell). In this application, the rechargeable battery is simply called a battery for description while using these names. In addition, a battery pack is sometimes called a battery pack, a battery system, or a battery module. In this application, while using the battery module in these nam...
