Patent ID: 8593111

Claim:
An assembled battery system comprising: an assembled battery including battery blocks connected in series, wherein each of the battery blocks includes a monitoring line and plural battery unit modules, the plural battery unit modules connected in parallel with each other within each battery block, each of the battery unit modules includes a chargeable battery unit connected in series with a fuse, each of the battery blocks further includes monitoring elements each of which includes a MOS-FET having a gate, a drain, and a source, the drain is connected to the monitoring line, and the fuse is connected between the gate and the source; a monitoring module which is connected to the battery blocks through the respective monitoring lines each of which commonly connects the monitoring elements in the battery block to monitor the monitoring elements in the respective battery blocks, wherein a blowout detecting signal is generated from the monitoring element in response to the blowout of the fuse and the monitoring module detects the blowout detecting signal through the monitoring line; a charge/discharge controller which is connected to the assembled battery so as to control a charge electrical power supplied to the assembled battery and/or a discharge electrical power supplied from the assembled battery; and a control module which generates a control signal to the charge/discharge controller on the basis of the blowout detecting signal to control the charge/discharge controller, the charging/discharging of the assembled battery being controlled depending on the control signal.
