Abstract
Typically, mobile equipment, such as tractors and heavy duty machinery, require engine start up systems to provide a strong surge of power necessary for starting engines. Traditional engine start up systems use lead-acid batteries for providing an initial voltage. However, monitoring the condition of these batteries may not be possible without adding extra sensors. Disclosed embodiments allow a battery condition monitoring system to monitor the condition of the batteries within an engine start up system based on available parameters without the need of new sensors. In particular, embodiments determine the condition of a battery based on the resistance determined from these available parameters.
