Abstract: A monitoring device has a control unit and monitoring units. A substrate of each monitoring unit has a high voltage section and a low voltage section. A cell monitoring IC detects a state of battery cells in the battery pack and is mounted in the high voltage side in a substrate of each monitoring unit. A photocoupler or capacitor is arranged between an input connector and the cell monitoring IC of each monitoring unit. A photocoupler or capacitor is arranged between an output connector of the substrate and the cell monitoring IC. The cell monitoring IC receives an input signal through the input connector and the photocoupler or capacitor, and transmits an output signal to the other monitoring unit or the control unit through the photocoupler or capacitor and the output connector.

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 to 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.
