    Abstract: A first switch connects a series circuit made up of a coil and a third capacitor between a high-voltage terminal and an intermediate-voltage terminal. A second switch connects the series circuit between the intermediate-voltage terminal and a low-voltage terminal. A third switch connects the series circuit with a power supply. A controller switches a mode among the following three modes. In a first mode, the first switch is closed, and the second switch and the third switch are open. In a second mode, the second switch is closed, and the first switch and the third switch are open. In a third mode, the third switch is closed, and the first switch and the second switch are open. The controller controls the switches such that the mode is repeated in order of the third mode, the first mode, the third mode, and the second mode.

    Abstract: A charge and discharge control device of a battery charges the battery with a constant current in a constant current mode. When the voltage of the battery corresponds to an end-of-charge voltage, the charge and discharge control device converts the constant current mode to a constant voltage mode and thereby charges the battery with a constant voltage. The end-of-charge voltage is set as a first end-of-charge voltage minus a negative electrode threshold potential from the full-charge voltage of the battery, and the negative electrode threshold potential is a potential value of the negative electrode where a negative electrode active material contained in the battery causes a phase change.
