<p><P>PROBLEM TO BE SOLVED: To provide a system for detecting states of respective secondary batteries by receiving power supply from the secondary batteries formed from serially connected secondary battery cells, the system capable of achieving effective utilization of electric power stored in the secondary batteries, optimum battery capacities and miniaturized batteries by maintaining discharge amount of each battery pack unit so that the discharge amount is always equal. <P>SOLUTION: A secondary battery monitoring device is constructed by serially connecting battery units formed from one or more chargeable and dischargeable battery cells and monitoring devices that detect states of the battery cells. In each of the battery units, there are provided a first power supply circuit that supplies electric power to the monitoring devices and a second power supply circuit that supplies electric power evenly from all the battery units. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
