Abstract
In an embodiment, a device comprises a controller configured to create a load pulse for a battery, measure battery voltage concurrently with the load pulse, measure battery current concurrently with the load pulse, calculate a battery resistance from the measured battery voltage and current and based on the battery resistance, calculate a maximum allowable current extractable from the battery, wherein the maximum allowable current is determined such that a voltage across the battery does not drop below a pre-specified threshold voltage when the maximum allowable current is drawn from the battery.
