Title:
２次電池の状態調節装置
Document Type and Number:
Japanese Patent JP5549635
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that, when lithium ion secondary cells or the like are used as battery cells Ca1 to Can and Cb1 to Cbn, the remaining capacity of the battery cells become excessively large or excessively small, resulting in the reliability thereof being deteriorated.SOLUTION: The cathodes and anodes of battery cells Ca1 to Can constituting a high voltage battery Ba are selectively connected to a cathode wiring Lp and an anode wiring Ln via a relay group RGa. Also, the cathodes and anodes of battery cells Cb1 to Cbn constituting a high voltage battery Bb are selectively connected to the cathode wiring Lp and the anode wiring Ln via a relay group RGb. As a result, either side of the high voltage batteries Ba and Bb has its battery cells charged with electricity from the battery cells on the other side.
