ASSEMBLED BATTERY MONITORING DEVICE, SECONDARY BATTERY APPARATUS, AND VEHICLE

摘要

According to one embodiment, a monitoring device includes a power supply circuit which powered by an assembled battery including secondary battery cells, and a monitoring IC powered by the supply circuit. The monitoring IC comprises a coulomb counter circuit configured to measure internal amperage consumption, an IC internal power supply circuit powered by the power supply circuit to generate a power supply voltage for use for an internal operation, and a calculation module configured to calculate a set value for a power supply voltage generated by the IC internal power supply circuit so as to determine a first amperage consumption target value to be a first amperage consumption measured value measured at the first time interval by the coulomb counter circuit.
