<P>PROBLEM TO BE SOLVED: To provide a battery module control system capable of reusing an arbitrary secondary battery module by using the simple and inexpensive system. <P>SOLUTION: In the battery module control system 1 wherein a plurality of switching circuits arranged on respective charge and discharge passages of a plurality of battery modules connected to each other in parallel are controlled at an ON and OFF state, the battery module control system 1 has a means for calculating an average impedance value of each module; a means for inputting a permissible maximum charge and discharge rate of each module; a means for calculating a permissible voltage difference of each module from an average impedance value of the calculated module and an average impedance value of an input module; a common voltage detection means for detecting voltage of a common charge and discharge passage of the plurality of modules connected to each other in parallel; and a voltage detection means for each module. When a difference between voltage detected by the common voltage detection means and the module voltage is larger than the permissible voltage difference, the switch circuit arranged on the charge and discharge passage is controlled to be turned off. <P>COPYRIGHT: (C)2011,JPO&INPIT |
