    摘要： Measurement of a cell voltage is executed immediately after diagnosis of a battery management device is ended. In a battery management device 10, current sources G11 and G12 repeatedly perform an energization operation to cause a current to flow to voltage detection lines L1, L2 and L3 with a magnitude of the current that enables each amount of charge stored in capacitors C11, C12, and C13 changed by one energization operation to fall within a range corresponding to a fluctuation width of terminal voltages of battery cells 21 and 22 during the energization operation when resistors R11, R12, and R13 are in a normal state. When the difference between the current terminal voltage of the battery cell 21 or 22 and the past terminal voltage of the battery cell 21 or 22 is larger than the predetermined threshold value, the microcomputer 130 diagnoses that the resistor R11, R12 or R13 is in the open state.

    摘要： A battery system monitoring device includes a plurality of battery monitoring circuits, which is respectively provided in cell groups, and a balancing resistor. Each of the battery monitoring circuits includes a cell voltage measurement unit to measure a cell voltage of each single battery cell at predetermined timing, a discharge switch to switch a state of a discharge current which flows from each single battery cell through the balancing resistor, and a balancing control unit configured to control the discharge switch. A filter circuit is connected between the cell voltage measurement unit and each single battery cell. The cell voltage measurement unit determines whether a cell voltage is measured within a transient response period corresponding to a time constant of the filter circuit and corrects a measurement value of a cell voltage by using a correction value correcting a result of the determination.
