Patent ID: 7656122

Claim:
A method for estimating a maximum discharge power of a battery, comprising: generating a signal indicative of a present state-of-charge of said battery, utilizing a sensor; calculating said present state-of-charge of said battery based on said signal, utilizing an arithmetic circuit operably coupled to said sensor; calculating a maximum discharge current of said battery utilizing said arithmetic circuit based on at least a minimum state-of-charge limit associated with said battery, said present state-of-charge of said battery, and a minimum voltage limit associated with said battery such that a future output voltage of said battery does not fall below said minimum voltage limit and a future state-of-charge of said battery does not fall below said minimum state-of-charge limit associated with said battery; and, calculating said maximum discharge power based on said maximum discharge current value, utilizing said arithmetic circuit, wherein said calculating said maximum discharge current is also based on a maximum current limit associated with said battery.
