Abstract
A control module for a battery that powers a load includes a compensation module that adjusts a shutoff voltage based on voltage and impedance of the battery and current drawn by the load from the battery as time the load is drawing current increases. A discharge control module restricts power to the load based on the adjusted shutoff voltage.
