1. An apparatus for controlling charging of a battery of a vehicle powered by an internal combustion engine comprising:

  • an input configured to receive an engine shutdown signal indicative that the engine will be shut down during an idle period to thereby conserve fuel;

    an engine shutdown delay configured to delay shutdown of the engine for a shutdown delay period in response to the engine shutdown signal; and

    charge boost circuitry configured to increase a charge signal applied to the battery of the vehicle during the engine shutdown delay period, wherein the charge signal is increased independently of a load on the charge boost circuitry.
