摘要： PROBLEM TO BE SOLVED: To provide a charging control circuit capable of uniformly charging battery units of a battery pack comprising a plurality of secondary battery units connected in series. SOLUTION: The charging control circuit is used for charging a battery pack where a plurality of battery units are connected in series, and includes a charging circuit, control circuit, and protection circuit. The charging circuit and the control circuit include a plurality of opening and closing units, and energy consumption units, respectively. The protection circuit is used for monitoring an internal voltage of each of battery units. If a difference of internal voltage between optional two batteries exceeds a particular value, the protection circuit performs switching between the opening and closing unit of the control circuit and that of the charging circuit. It reduces a charging current for the battery pack and, at the same time, shunts the charging current of the battery unit whose internal voltage is relatively high, so that the battery units of the battery pack are allowed to quickly reach a charge saturation state.
