An electric power supply control apparatus according to the present invention is connected in parallel to plural electric storage means and comprises: plural current measurement means which respectively measure the currents of the plural storage means connected in parallel; plural voltage measurement means which respectively measure the voltages of the plural storage means connected in parallel; plural switching means which respectively disconnect and connect the plural electric storage means from and to the parallel connection; state detection means which receives the outputs of the current measurement means and the outputs of the voltage measurement means and outputs the respective states of the plural electric storage means; and charging and discharging means which receives the outputs of the state detection means and charges and discharges the plural electric storage means. The charging and discharging means judges the deterioration states of the plural electric power storage means from the outputs of the state detection means and, based on the judged respective deterioration states of the plural electric storage means, controls switching of the plural switching means.
