<P>PROBLEM TO BE SOLVED: To provide a highly versatile power supply capable of facilitating system design at a low cost, and to provide a power supply system and a control method therefor. <P>SOLUTION: The power supply system comprises: a plurality of battery modules M1, M2, ..., Mn each having a secondary battery 10 which can store electric power by charging, a charge/discharge circuit 20 which regulates the charging and discharging power of the secondary battery 10, and power supply I/O terminals P11, P12, ..., Pn1, Pn2 used for input/output of DC power of the charge/discharge circuit 20 and arranged in parallel connection; and a host controller 40 which transmits an output power command value at the time of powering and a charging power command value at the time of charging to the battery modules M1, M2, ..., Mn. All battery modules M1, M2, ..., Mn share either the residual capacity of battery and/or the depth of discharge of the battery modules M1, M2, ..., Mn. <P>COPYRIGHT: (C)2012,JPO&INPIT |
