Abstract
A method and apparatus is provided for determining how a vehicle battery would perform when used to start a vehicle. A discharge voltage/current of the battery is predicted as a function of a battery dynamic parameter, an open circuit voltage of the battery, a battery temperature and a fixed current/voltage value at which the battery is to be discharged. This discharge voltage/current value is compared to a minimum starting voltage/current required to start the vehicle in which the battery is employed and an output indicative of a starting capability of the battery is provided.
