摘要： Even with a large ripple voltage superposed on a voltage of a battery cell, the voltage of the battery cell can be measured accurately. In a battery monitoring device, a supply circuit, based on a reference voltage inputted from an assembled battery, generates a driving voltage for driving each of switching elements, of a selection circuit and supplies the driving voltage to the selection circuit. The reference voltage is inputted from the assembled battery to the supply circuit via a detecting filter circuit. As a result, a time constant of a route through which the reference voltage is inputted from the assembled battery to the supply circuit is approximately equal to time constants of detecting filter circuits.

摘要： Communication distance can be extended in a battery system that transmits states of the battery cells by wireless communication. Each of cell controllers wirelessly transmits measurement result of states of battery cells in cell groups to a battery controller, by using an electric power supplied from the battery cells in the cell groups. The battery controller continuously transmits unmodulated carrier wave to each of the cell controllers. Each of the cell controllers changes an impedance for the unmodulated carrier wave transmitted from the battery controller at a predetermined timing in dependence on the measurement result of the states of the battery cells in the cell groups. Due to this, the measurement result of the states of the battery cells in the cell groups is wirelessly transmitted to the battery controller.

摘要： Cell voltage measurement is executed immediately after termination of diagnosis on a cell voltage detection function. In a battery managing device 10, a voltage detecting unit 140 detects a terminal voltage of each of battery cells 21 and 22. An RC filter 110 is electrically connected to voltage detecting lines L1, L2, and L3, and a status variation causing unit 130 causes an electrical status variation with respect to the voltage detecting lines L1, L2, and L3. A voltage fluctuating unit 120 fluctuates the terminal voltage of the battery cells 21 and 22 in response to the electrical status variation that is caused by the status variation causing unit 130. A microcomputer 150 diagnoses the voltage detecting unit 140 on the basis of a detection result of the terminal voltage of the battery cells 21 and 22 by the voltage detecting unit 140 when the terminal voltage of the battery cells 21 and 22 is fluctuated by the voltage fluctuating unit 120.

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.
