Dynamic battery state-of-charge and capacity determination |
摘要 |
A battery pack comprising a plurality of series arranged module has a state-of-charge and capacity associated therewith that are determined through dynamic operation thereof including both charge and discharge cycling. Amp*hour integration techniques are used to update state-of-charge until one of the plurality of modules is deeply discharged, at which time state-of-charge is updated in accordance with measured dynamic battery parameters of the deeply discharged module and capacity is updated in accordance with the newly calculated state-of-charge thereby accounting for capacity loss throughout the pack's cycle life. Alternatively, amp*hour integration techniques are used only at relatively high states of charge and dynamic parameter techniques are employed thereafter.
