Zusammenfassung: | A power supply apparatus has a combined power source with power cells configured electrically independently. A switch arbitrarily changes connection paths of the power cells by selectively connecting power cell terminals through switching elements. A voltage detector detects differences in electrical potentials between the power cell terminals. A controller controls ON-OFF states of the switching elements by controlling the switch by a control signal generated based on voltage signals representing the differences in electrical potentials detected by the voltage detector so as to isolate one of the power cells to stop a supply of electric power therefrom when a voltage generated in the power cell has dropped to a specified voltage or lower. The controller restarts the supply of electric power from the power cell whose power supply has been stopped when the duration of a down time of the power cell has reached a predetermined time or longer. |
