1. An electric storage device management apparatus, comprising:

  • a controller configured to;

    perform a voltage drop determination to determine a voltage drop value of a conductive member that connects electric storage devices; and

    determine a voltage between terminals of one of the electric storage devices to determine a voltage value between the terminals of the one of the electric storage devices after the voltage drop determination;

    a voltage detector connected to the electric storage devices via the conductive member and configured to detect a voltage value of a current path including the one of the electric storage devices and the conductive member;

    a memory storing a resistance value of the conductive member; and

    a current detector configured to detect a current value of a current flowing through the conductive member,wherein the controller is further configured to;

    determine the voltage drop value of the conductive member based on the resistance value of the conductive member and the current value of the current flowing though the conductive member in the voltage drop determination; and

    determine the voltage value between the terminals of the one of the electric storage devices based on the voltage value of the current path and the voltage drop value of the conductive member in the determining the voltage between the terminals, andwherein the controller manages the electric storage devices by using the determined voltage value to control charging and discharging of the electric storage devices.
