Abstract: A battery monitoring apparatus monitors a battery pack configured by a plurality of battery cells. The battery monitoring apparatus includes a main monitoring unit, a sub monitoring unit and a control unit. The main monitoring unit monitors a plurality of physical quantities indicating a battery state of the battery pack. The sub monitoring unit monitors a part of the physical quantities separately from the main monitoring unit. The control unit detects malfunction of the battery pack on the basis of at least one of a monitoring result of the main monitoring unit and a monitoring result of the sub monitoring unit.
Abstract translation: 电池监视装置监视由多个电池单元构成的电池组。 电池监视装置包括主监视单元，副监视单元和控制单元。 主监控单元监视指示电池组的电池状态的多个物理量。 子监视单元监视与主监视单元分开的部分物理量。 控制单元基于主监视单元的监视结果和子监视单元的监视结果中的至少一个来检测电池组的故障。

Abstract: A battery monitoring apparatus capable of reducing power consumption. At least one monitoring integrated circuit (IC) is electrically connected to a high-voltage battery formed of a plurality of cells and configured to monitor the high-voltage battery in a plurality of modes of operation. A low-voltage power supply circuit can deliver power of a lower voltage than the power of the high-voltage battery to the at least one monitoring IC. A power supply to the at least one monitoring IC is selected from a group of the high-voltage battery and the low-voltage power supply circuit depending on the mode of operation the at least one monitoring IC.
