<P>PROBLEM TO BE SOLVED: To provide a battery control system capable of quickly determining generation of multifunction so as to be able to carry out any countermeasure so as not to generate the problem caused by the multifunction when the booster circuit is out of order. <P>SOLUTION: The battery control system 1 has a battery 2 and the booster circuits 41a, 41b of the same, boosting observing circuits 42a 42b for detecting the voltage of the battery when boosting, and a battery voltage control section 74 driving the booster circuits 41a, 41b and boosting the voltage of the battery 2 when starting an engine 8. The battery voltage control section 74 drives the booster circuits after boosting with the starting of the engine 8 and when the boosting is not needed and determines the multifunction of the booster circuits 41a, 41b based on the voltage of the battery detected by the boosting observing circuits 42a, 42b when boosted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
