Abstract
A charging apparatus charges a battery assembly including a plurality of secondary batteries. After the charging apparatus detects a full charge level, the apparatus stops charging. Then, when the charge level of the battery assembly falls below a predetermined charge level, the charging apparatus resumes charging in order to maintain the secondary battery assembly at a full charge level. The charging apparatus monitors the charging after charging is resumed. When the charging apparatus detects that the charging process after resumption of charging is abnormal, the apparatus modifies the charging. For example, when the battery assembly includes a malfunctioning secondary battery causing an abnormal charge resumption, the apparatus modifies the charging to prevent the other normal secondary batteries in the secondary battery assembly from being overcharged to avoid deterioration.
