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: 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.

Abstract: A circuit protector includes a plurality of detection lines that connect between a battery pack and a monitoring circuit, an overvoltage protection element connected between the detection lines that keeps the voltage applied to the monitoring circuit at a fixed voltage, and a circuit protection element disposed in each detection line that disconnects an electrical link between the monitoring circuit and the battery pack when a current beyond a predetermined current value flows into the detection line. When the excess voltage occurs in the battery pack, the overvoltage protection element maintains between each detection line in a short circuit state, and the circuit protection element disconnects the electrical link between the battery pack and the monitoring circuit by a short-circuit current that flows between the detection lines via the overvoltage protection element.
