Abstract:
1. A storage battery control device comprising: a calculation unit which calculates a voltage drop caused to an electric power system when a storage battery is connected to the system; a resistor element having a resistance value set by a control unit; a control device that controls a charging load on the storage battery; a sensor that measures an electric current value and a voltage value of a load current applied from the electric power system to the storage battery, wherein the voltage drop is calculated based on a difference in a voltage value measured when the load current passes through the resistor element and when the load current does not pass through the resistor element when the load current is applied from the electric power system to the storage battery, wherein the control unit outputs the control command signal based on the calculated voltage drop to the control device that controls the charging load on the storage battery, and wherein the control command signal is a resistance setting signal for setting the resistance value of the resistor element for limiting the electric current supplied from the electric power system to the storage battery.
