PROBLEM TO BE SOLVED: To provide a secondary battery pack which can include various kinds of secondary batteries. SOLUTION: The charging current, flowing into respective battery cell groups which are contained in one secondary battery pack consisting of secondary batteries having different characteristics, is limited only to the allowable charging current value of the battery cell constituting the battery cell groups. When the charging current is lowered further than the full-charge discriminating current set by the battery cell, a current limiter means for stopping the inflow of the charging current.
