Abstract
A vehicle includes an engine having a throttle body, a battery, e.g., a 12-volt battery, and a battery-charging system electrically connected to the battery and configured to convert mechanical motion of the engine into electricity to charge the battery. A controller of the vehicle is programmed to, in response to an opening of the throttle body being less than an opening threshold and a state of charge of the battery (battery SOC) being less than a first charge threshold, set the battery-charging system to output a first power, wherein the charge threshold is based on a measured capacity of the battery and a measured key-off load. The controller is further programmed to, in response to the opening being less than the opening threshold and the battery SOC exceeding the first charge threshold but being less than a second charge threshold, set the battery-charging system to output a second power that is less than the first power.
