摘要： 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.
