Abstract
A system comprises: a portable computer main body having therein a power source circuit section having a battery pack; and a plurality of auxiliary battery units which are mechanically connected and fixed to a casing of the computer main body and are electrically connected in series to a power source input terminal. A charge/discharge control section is provided for each of the auxiliary battery units. The charge/discharge control section sequentially charges from the auxiliary battery unit locating on the computer main body side when charging. On the contrary, the charge/discharge control section sequentially discharges from the auxiliary battery unit on the opposite side which is farthest from the computer main body when discharging. There is also a system construction having a single auxiliary battery unit.
