1. A cooling arrangement for an extended range electric vehicle having an auxiliary power module, a first duct, and an auxiliary power module blower configured to deliver air through the first duct to the auxiliary power module when the auxiliary power module blower is operated, the cooling arrangement comprising:
the auxiliary power module blower; an onboard charging module; a charging port coupled to the onboard charging module, the charging port being accessible from a position external to the extended range electric vehicle; and a second duct having a first end positioned proximate the charging port and a second end in fluid communication with the first duct, the second end being directly fluidly coupled with the first duct at a location upstream of the auxiliary power module blower, and the second duct configured to deliver ambient air from outside of the extended range electric vehicle to the onboard charging module when the auxiliary power module blower is operated while the extended range electric vehicle is off, wherein the auxiliary power module blower is configured to operate while the extended range electric vehicle is off and while the charging port is accessed, whereby the auxiliary power module blower delivers air from outside the extended range electric vehicle to the onboard charging module, wherein the auxiliary power module blower unilaterally cools both the auxiliary power module and the onboard charging module, and wherein the auxiliary power module blower, the onboard charging module, the charging port, and the second duct are mounted to the extended range electric vehicle.
