Abstract
In an assembled battery system, parallel battery blocks are connected in series. Each of the battery blocks includes battery unit modules connected in parallel, and each of the modules includes a battery unit and a fuse connected in series. The battery block is provided with a common connection line connected to a fuse monitoring module, and MOS-FETs each having a gate, source and drain, wherein the fuse is connected between the gate and source, and the drain is connected to the connection line. The FET is turned on and a voltage is applied to the connection line through the FET from the battery unit, when the fuse is blown out. Thus, the fuse monitoring module can detects the blowout of the fuse, and a control module can turn off a control switch to stop charging/discharging of the assembled battery in accordance with the control signal from the fuse monitoring module.
