<P>PROBLEM TO BE SOLVED: To provide a battery system in which over-charging of an electrolyte secondary battery is prevented without installing a special control circuit. <P>SOLUTION: The battery system 1 is formed by connecting, in parallel, an electrolytic solution secondary battery group 3 in which a plurality of electrolytic solution secondary batteries are connected in series, and a solid electrolyte secondary battery group 5 in which a plurality of solid electrolyte secondary batteries 4 are connected in series. When the over-charging occurs, the solid electrolyte secondary batteries 4 are short-circuited before the electrolytic solution secondary batteries are short-circuited. <P>COPYRIGHT: (C)2013,JPO&INPIT |
