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: In a battery monitoring system, an input current flowing through an input portion of an isolator member is larger than an output current flowing through an output portion of the isolator member. The output portion is electrically isolated from the input portion. The input and output portions of the isolator member are connected respectively to first and second circuits included in a group of the control circuit and the plurality of monitoring circuits. The first and second circuits are selected for the isolator member, The first and second circuits respectively serve as a sender and a receiver. The isolator member transfers serial data sent from the sender to the receiver while the sender and the receiver are electrically isolated from each other. The isolator is mounted on a substrate included in the control and monitoring substrates. The receiver is mounted on the substrate.
