Abstract
A battery control module is provided for use with a battery and includes a voltage measuring module that measures battery voltage, a current measuring module that measures battery current, and a state of charge (SOC) module that communicates with the current and voltage measuring modules. The SOC module estimates an open circuit voltage based on the battery current and the battery voltage and estimates a SOC based on the open circuit voltage.
