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.

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 control method of replenishing anode fuel for DMFC system is provided. The DMFC system includes at least a fuel cell, a cathode humidity-holding layer, a fuel distribution unit, a control unit, a liquid fuel replenishment device, a fuel storage region, and a temperature detecting device. The temperature detecting device is for detecting an actual temperature of the fuel cell. The control method of replenishing anode fuel includes utilizing the control unit to adjust a fuel replenishment amount supplied from the liquid fuel replenishment device. The fuel replenishment amount is the sum of a basic replenishment amount and a replenishment amount for temperature correction. The basic replenishment amount is a function of actual discharge current of the fuel cell. The replenishment amount for temperature correction is a function of the difference between the actual temperature of the fuel cell and the target temperature.
