    摘要: In accordance with various embodiments, there is a method for determining the capacity of a battery (100). Various embodiments include applying a predetermined current ramp (120) to a fully charged lead-acid battery (105) while measuring a battery terminal voltage (120). An l up can be determined (140, 150), where the l up is a transition from charging to overcharging. A specific gravity of the lead-acid battery can also be determined (160). The capacity of the lead-acid battery can then be determined from the l up using a correlation function that describes the relationship of the l up to the capacity (170), where the correlation function depends on the specific gravity of the lead-acid battery.
