  • Publication number: 20200266644
    Abstract: A storage battery system includes a cell module including storage battery cells, a battery management unit configured to maintain a contactor having a normally open contact in a closed state, while being supplied with power, and a power supply control circuit that DC to DC converts the power of the cell module for supply to the battery management unit. The power supply control circuit includes an SOC estimator that determines from a voltage of the cell module whether or not the cell module is in an overdischarge state, and after determining that the cell module is not in the overdischarge state, outputs a status signal to the power supply control circuit. In response to no receipt of the status signal from the SOC estimator, the power supply control circuit interrupts the power supply to the battery management unit from the cell module.

  • Patent number: 10581238
    Abstract: A storage battery device includes a battery unit, a first circuit breaker, a second circuit breaker, and a control unit. The first circuit breaker switches between connecting and disconnecting a first-electrode side of the battery unit and an external device. The second circuit breaker switches between connecting and disconnecting a second-electrode side of the battery unit and the external device. The control unit supplies power to the first circuit breaker and the second circuit breaker in sequence with the power supplied to the second circuit breaker offset relative to the power supplied to the first circuit breaker by a time period equal to or longer than a time difference required for a sum of currents flowing through the first circuit breaker and the second circuit breaker to reach an upper bound current that is set as an upper bound of a current.

  • Publication number: 20190079119
    Abstract: A storage battery management device includes a connector, storage, a drive voltage controller, a determiner, and a current sensor controller. The connector is connectable to a current sensor. The storage stores current sensor information including an output range of normal output values and each current-sensor type indicating a type of a current sensor connectable to the connector in association with each other. The drive voltage controller causes a current to flow through a current sensor while varying a voltage to be applied to the current sensor. The determiner determines, based on whether an output value that is received via the connector from the current sensor falls in the output range corresponding to the current-sensor type, the current-sensor type of the current sensor connected to the connector. The current sensor controller controls the current sensor in accordance with the determined current-sensor type.
