Abstract
A process for monitoring the status of a battery. Steps of the process include measuring a battery current and comparing the battery current to a predetermined threshold. A battery status is determined as one of charging, discharging and quiescent. For a battery charging status determination, the charging state of charge of the battery is computed. For battery discharge status determination, the discharge current is compared to a predetermined threshold. Based upon the discharge current comparison, a basis for the discharge current is selected from one of a plurality of predetermined discharge conditions and the discharging state of charge of the battery is computed for the select discharge condition. For a quiescent status, the quiescent state of charge of the battery is computed. The computed state of charge of the battery is provided in a quantitative form.
