ASSEMBLED BATTERY MONITORING DEVICE

摘要

A battery monitoring device monitors a battery having a plurality of cell groups in which a plurality of cells is connected in series. The battery monitoring device comprises at one or more integrated circuit units, each of which corresponds to each cell group, that respectively measure the voltages of the cells of the cell group and performs cell balancing in order to adjust the capacities of the cells of the cell group; a control unit that controls the integrated circuit unit; and a power supply unit that supplies power to the control unit. The control unit causes the integrated circuit unit to start or to stop cell balancing, and sets a timer period for starting or stopping supply of the power.
