Charging method for a rechargeable battery and charging architecture therewith
A charging method for a rechargeable battery and a related charging architecture are provided. The provided charging method includes following steps. A characteristic curve of the rechargeable battery related to charge cycle vs. a residual capacity of a non-constant voltage charging stage under a warranty life limitation is provided. An expected residual capacity corresponding to a condition when a terminal voltage of the rechargeable battery reaches a limited charge voltage is found from the characteristic curve related to the charge cycle vs. the residual capacity of the non-constant voltage charging stage by using a current charge cycle count of the rechargeable battery. A real residual capacity corresponding to a condition when the terminal voltage of the rechargeable battery reaches the limited charge voltage approaches to the expected residual capacity by adjusting a charging current of the rechargeable battery.
