Abstract
Described herein are methods for determining, based on actual crank conditions, an ability of a battery connected to an electric starter motor, to start an internal combustion engine, wherein the battery is a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel. The method may include: receiving battery temperature data, representing a temperature of the battery at a time of cranking the internal combustion engine; receiving voltage data monitored from the battery, determining an instantaneous minimum voltage of the battery during the time of cranking the internal combustion engine; and determining a capability of the battery to crank the internal combustion engine based on the battery temperature data and the instantaneous minimum voltage of the battery.
