<P>PROBLEM TO BE SOLVED: To provide a power supply system which, configured of a plurality of cell blocks, is simplified in overall circuitry to reduce the total cost while detecting the voltages of cells of each cell block and outputting them to externally connected equipment. <P>SOLUTION: A power supply system comprises a plurality of cell blocks 1 provided with a high-voltage battery 2 formed by connecting chargeable cells 11, a voltage detecting circuit 4 that detects voltages via a detection line 17 connected to the cells 11 constituting the high-voltage battery 2, and a CPU 5 that calculates the state of the cells 11 from the voltages detected by the voltage detecting circuit 4 and outputs a state signal of the cells 11 to externally connected equipment. The cell block 1 comprises a main cell block 1A mounted with the CPU 5 and a subordinate cell block 1B connected to this main cell block 1A via a connection line 9 and not mounted with the CPU 5, and the main cell block 1A detects the voltages of the cells 11 of the subordinate cell block 1B via the connection line 9. <P>COPYRIGHT: (C)2013,JPO&INPIT |
