The idle management system includes an environmental package adapted to interconnect with a vehicle environmental package to regulate the climate within a vehicle compartment of a vehicle. The environmental package may be in electrical communication with the power storage unit to receive electrical power therefrom. A controller may be in communication with the power storage unit to derive electrical power therefrom, and the controller may be in communication with the environmental package to regulate the operation thereof. The idle management system may draw electrical power from the power storage unit to be operable with an engine in an engine OFF condition.
