According to one embodiment, an assembled battery monitoring device (13) includes an assembled battery monitoring device power supply circuit (131) which powered by an assembled battery (14) including a plurality of secondary battery cells, and an assembled battery monitoring IC (130) powered by the assembled battery monitoring device power supply circuit (131). The assembled battery monitoring IC (130) includes a coulomb counter circuit (139) configured to measure internal amperage consumption, an IC internal power supply circuit (132) powered by the assembled battery monitoring device power supply circuit (131) to generate a power supply voltage for use for an internal operation, and a power supply voltage set value calculation module (130A) configured to calculate a set value for a power supply voltage generated by the IC internal power supply circuit (132) so as to determine a first amperage consumption target value (TTL) to be a first amperage consumption measured value (ITL) measured at the first time interval (TL) by the coulomb counter circuit. |
