PROBLEM TO BE SOLVED: To provide a battery system capable of dividing entire system into plural insulated blocks to reduce the capacity and withstand voltage of each insulated power source so that the power source voltage of the entire battery system is equal to or larger than a withstand voltage of each insulated power source.SOLUTION: The battery control system is constituted of plural insulated blocks each of which includes plural batteries which are connected to each other in series. Each of the insulated blocks includes one or more battery controllers. The battery controller includes: a monitor circuit for monitoring the batteries; and a first insulated power source that supplies the power to the monitor circuit. The first insulated power source in each of the insulated blocks uses a common power line as a power source and the power lines of each of the insulated blocks are connected to each other via a second insulated power source. |
