    • A charging method fit for use with and applicable to a rechargeable battery is provided. The charging method involves charging the rechargeable battery to a first preset voltage and then charging the rechargeable battery to a second preset voltage. The charging method includes the steps of: (a) using the first preset current as a charging current, and performing the constant current charging of the rechargeable battery by the first preset current until the rechargeable battery reaches the first preset voltage for the first instance; (b) subtracting a current difference value from the charging current used by the rechargeable battery to reach the first preset voltage in the preceding instance so as to obtain a new charging current, and performing the constant current charging of the rechargeable battery by the new charging current thus obtained until the rechargeable battery reaches the first preset voltage again; (c) repeating step (b) until the new charging current equals a second preset current; and step (d) using the second preset current of step (c) as another new charging current, and performing the constant current charging of the rechargeable battery by the second preset current until the rechargeable battery reaches a second preset voltage for the first instance.
    • 提供适用于可充电电池的充电方法。 充电方法包括将可再充电电池充电到第一预设电压,然后将可再充电电池充电到第二预设电压。 充电方法包括以下步骤:(a)使用第一预置电流作为充电电流,并且通过第一预设电流执行可再充电电池的恒定电流充电直到可再充电电池首次达到第一预置电压; (b)从先前的例子中减去由可再充电电池使用的充电电流达到第一预设电压的电流差值,以获得新的充电电流,并通过新充电来执行可再充电电池的恒定电流充电 直到可再充电电池再次达到第一预置电压为止; (c)重复步骤(b),直到新的充电电流等于第二预设电流; 和步骤(d)使用步骤(c)的第二预设电流作为另一新的充电电流,并且通过第二预设电流执行可再充电电池的恒定电流充电,直到可再充电电池达到第一预定电压为止。
