  • 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.
