The terminal voltage rises as the capacity is restored by charging, and the battery becomes fully charged when it reaches the set voltage. If a fully charged battery is still charged, electric energy is not absorbed and side reactions such as electrolysis of the electrolytic solution occur. As a result, although the capacity does not increase, the terminal voltage exceeds the set voltage, the battery is overcharged and damaged, the capacity decreases, and the cycle life shortens. Therefore, it is necessary to control the terminal voltage to charge the non-aqueous secondary battery.

Therefore, in the case of rapid charging, it is difficult to accurately determine the end of charging.
