Abstract
A voltage monitoring apparatus of an assembled battery has a voltage monitoring section that monitors each voltage of the assembled battery formed by a plurality of cells, and a power supply circuit that acquires a voltage from the assembled battery to generate a power supply voltage of low voltage, and supplies the power supply voltage to a load. The assembled battery is configured by a series circuit of a first block, which includes a plurality of cells or a singular cell, and a second block, which is configured by a plurality of cells or a singular cell. The power supply circuit acquires a voltage from both ends of the second block. The voltage monitoring apparatus further has a power transmission circuit that acquires a voltage from both ends of the first block and supplies a power corresponding to the acquired voltage to at least the second block.
