Abstract: A method for estimating battery degradation is provided. In this method, a remaining capacity is obtained by looking up a device characteristic table according to a steady open circuit voltage of a battery. Besides, a constant current is provided to charge the battery, and when a terminal voltage of the battery reaches to a charging preset voltage, a constant voltage is provided to charge the battery. The transition point information at the transition from a constant current mode to a constant voltage mode, which includes a transition point estimated open circuit voltage, a transition point voltage, a transition point current and a transition point battery temperature, is analyzed based on voltage, current, temperature and capacity information measured during the charging process. A battery degradation index is calculated from the transition point information.

Abstract: 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.
