Document Type and Number:
Japanese Patent JP7170904
Kind Code:
B2
Abstract:
The present invention relates to a method and system for detecting connection failure of a parallel connection cell, and for a battery that is being discharged by the operation of an external device (e.g. vehicle), by detecting whether there is a section matching the amount of change in the discharge voltage value when a cell connection failure condition occurs due to a pre-prepared CID operation or an open parallel connection line from the change in the discharge voltage value of the battery being discharged, a cell connection failure due to a CID operation of a corresponding battery or an open parallel connection line may be detected.
