    摘要: In accordance with various embodiments, there is a method for determining the specific gravity of a battery. Various embodiments include the steps of applying an increasing current ramp to a battery and measuring a response voltage of the battery when the increasing current ramp is applied to the battery. When the current ramp reaches a predetermined current a decreasing current is supplied to the battery and the battery's voltage response is measured. The specific gravity of the battery can be determined based on the voltage response of the battery to the applied current ramp.

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