Abstract
A system for controlling charging of a battery of a vehicle powered by an internal combustion engine. The system includes an input that receives an engine shutdown signal indicative that the engine will be shut down during an idle period to thereby conserve fuel. An engine shutdown delay delays shutdown of the engine for a shutdown delay period in response to the engine shutdown signal. Charge boost circuitry increases a charge signal applied to the battery of the vehicle during the engine shutdown delay period.
