An auxiliary power unit for an electric vehicle fits within a well that is integrated with the structure of the electric vehicle. A housing for the auxiliary power unit fits within the well, with a lid on the housing covering an opening for the well, flush with adjoining surfaces. The auxiliary power unit includes a charge port and power outlet(s), and is configured for pass-through charging of the propulsion battery, or to recharge the propulsion battery. The auxiliary power unit is removable, and may be used separately from the electric vehicle or in another instance of the electric vehicle. Battery modules within the auxiliary power unit are also removable and have a power outlet for use separately from the auxiliary power unit. Safety interlocks for hot swapping and quick disconnects for electrical connectors and coolant hoses are provided on the auxiliary power unit and/or removable battery modules.
