PROBLEM TO BE SOLVED: To construct a power source system of high safety, capable of suppressing deformation of a secondary battery even in receiving the entire current from a generator as a charge current, with the use of the secondary battery of which energy density per unit weight is high. SOLUTION: The power source system includes a battery assembly where a first battery pack in which a plurality of elementary batteries A are connected in series and a second battery pack where a plurality of elementary batteries B are connected in series are electrically connected in parallel, and a generator. Average charge voltage V1 of the first battery pack is lower than average charge voltage V2 of the second battery pack. COPYRIGHT: (C)2009,JPO&INPIT |
