<P>PROBLEM TO BE SOLVED: To construct a high-safety power supply system that suppresses deformation of a secondary battery even if receiving all currents from a power generator as charging currents while using the secondary battery having high energy density per unit weight. <P>SOLUTION: The power supply system includes a power generator and a battery aggregate constituted by electrically connecting in parallel a first battery pack, formed by connecting a plurality of unit cells (A) in series, and a second battery pack formed by connecting a plurality of unit cells (B) in series. An average charging voltage V1 of the first battery pack is set smaller than an average charging voltage V2 of the second battery pack. The first battery pack is connected with a resistor in series. <P>COPYRIGHT: (C)2009,JPO&INPIT |
