  • BATTERY UNIT
    Publication number: 20130149572
    Abstract: A battery unit (1) includes battery subunits (11, 12, 13) and a voltage monitoring circuit (30). The battery subunits (11, 12, 13) includes battery modules (110, 120, 130), each having a secondary battery cell (111, 121, 131) and a fuse (112, 122, 132) connected in series. The voltage monitoring circuit (30) monitors the voltage across the terminals of each of the battery subunits (11, 12, 13). Each of the battery subunits (11, 12, 13) includes one battery module or a plurality of battery modules (110, 120, 130) connected in parallel.
