1. A motor vehicle comprising:
- a supply battery for providing electric power to drive the vehicle;
a trunk compartment having an upper opening and a lower opening and a plurality of side walls extending substantially vertically therebetween, a trunk compartment floor extending between inwardly facing surfaces of the plurality of side walls to define a storage space above the trunk compartment floor and an accommodation space below the trunk compartment floor, the trunk compartment floor being vertically translatable along the inwardly facing surfaces of the side walls between a lower position where the trunk compartment floor is substantially at lower ends of the side walls and an upper position where the trunk compartment floor is in proximity to the upper ends of the side walls to adjust a storage space volume and an accommodation space volume;
a lid that is hinged to a top end of one of the plurality of side walls at the upper opening and opposed to the trunk compartment floor, the lid being selectively openable for providing access to the storage space of the trunk compartment between the trunk compartment floor and the lid, andat least one auxiliary battery selectively insertable into the accommodation space through the lower opening for increasing a driving range of the vehicle and removable from the accommodation space through the lower opening for reducing weight and changing vehicle dynamics, whereinthe trunk compartment floor is moved to the upper position to increase the accommodation space volume for accommodating the auxiliary battery and the trunk compartment floor is moved to the lower position when the auxiliary battery is removed to increase the storage space volume.

Abstract
A battery system for driving an electric motor of a hybrid vehicle or of an electric vehicle has an exchangeable auxiliary battery to improve the comfort, performance and/or the range of the vehicle. The auxiliary battery can be placed from below into a space beneath the trunk compartment floor. The trunk compartment floor is vertically movable to increase the size of the trunk compartment when the auxiliary battery is not being used.
