PROBLEM TO BE SOLVED: To provide a charge control method wherein, in a general-purpose charger which charges a combined battery set 2 with a plurality of unit cells connected in series, the performance of the general-purpose charger is exerted to the utmost regardless of the number of unit cells in the combined battery set 2, by detecting the battery voltage of the combined battery set 2 and controlling the charging current to a value corresponding to the battery voltage or the number of unit cells determined based on the battery voltage. SOLUTION: The charge control method involves a battery voltage detecting means 40 for detecting the battery voltage of a combined battery set 2, a charging current control means 60 which controls a charging current, and a microcomputer 50. A detection signal from the battery voltage detecting means 40 is taken into the microcomputer 50. The microcomputer 50 sends a set value for setting the detection signal or the number of unit cells of the combined battery set 2 determined based on the detection signal to the charging current control means 60 through a charging current setting means 80. Thus, the charging current is controlled to a specified value. COPYRIGHT: (C)2003,JPO
