Abstract

[Problem] To prevent the overcharging of secondary batteries and to carry out optimal charging in response to the electrical characteristics of each secondary battery. [Solution] A selecting-switch switching circuit (30) has thyristors (32) respectively connected to each secondary battery (10), and a control circuit (40) which controls the ON/OFF switching of the plurality of thyristors (32). By the control circuit (40) controlling the ON/OFF switching of the thyristors (32), a charge path is formed to an arbitrary secondary battery (10) and the charge path to the other secondary batteries is cleared. A constant current supply generation circuit (20) is provided with a chopper circuit configured from: an inductor (L) connected between a supply output terminal (OT) and a supply input terminal (IT); and a charge switch (22) which is connected in serial to the inductor (L) and of which the ON/OFF switching is controlled by the control circuit (40). The chopper circuit is connected to an external power supply (EP) and charges the secondary batteries (10).
