摘要： 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.

摘要： First and second resistor series divide a predetermined voltage range to generate first reference voltages and second reference voltages, respectively. First and second switch controlling circuits select respective ones of the first reference voltages and the second reference voltages. A comparing unit generates a logical signal representing a logical value by comparing a combined transistor current based on the selected first and second reference voltages with a transistor current based on an input signal. The first switch controlling circuit specifies two adjacent first reference voltages where the logical value is inverted by sequentially selecting the first reference voltages, and determines to select one of the adjacent reference voltages. Te second switch controlling circuit specifies two adjacent second reference voltages where the logical value is inverted by sequentially selecting the second reference voltages, and determines to select one of the adjacent reference voltages.
