1. A motor vehicle driven at least partly by electrical energy, the motor vehicle comprising:
- a rear end;
a rear axle in proximity to the rear end;
two rear wheels driven by the rear axle;
an underbody surface;
a receptacle above the underbody surface, forward of the rear axle and at least partly between rear wheels of the motor vehicle;
an electrical energy storage device attached to a supporting structure of the motor vehicle and disposed in the receptacle, the electrical energy storage device being operative for supplying the electrical energy for driving the motor vehicle;
a maintenance opening in the underbody surface at the receptacle and being configured for accessing the electrical energy storage device in the receptacle for maintenance or installation work; and
a maintenance cover pivotally attached to the underbody surface along a hinge line substantially adjacent the maintenance opening and at a side of the maintenance opening farthest from the rear axle and forward of the rear axle, the maintenance cover having a free end opposite the hinge line and disposed forward of the rear axle, the maintenance cover further having side edges extending from the hinge line to the free end, locks being disposed on the side edges of the maintenance cover substantially adjacent the free end and forward of the rear axle for locking the free end of the maintenance cover to the underbody surface, the maintenance cover being repeatedly movable between a closed position where the maintenance cover closes the maintenance opening and an open position where the free end of the maintenance cover is spaced from the maintenance opening for accessing the electrical energy storage device.

Abstract
A motor vehicle has an electrical drive machine that is supplied with electrical energy by an electrical energy storage device, and has an underbody region or surface (5). The electrical energy storage device is accessible for maintenance and/or installation work via a maintenance cover (10) in the underbody surface (5) to reduce time required for maintenance and/or installation work.

7. A hybrid or electric motor vehicle, comprising:
-
a rear axle; rear wheels mounted on the rear axle; an underbody surface; a receptacle above the underbody surface and forward of the rear axle and at least partly between the rear wheels; a traction battery attached to a supporting structure of the motor vehicle and disposed in the receptacle, the traction battery being operative for supplying electrical energy for driving the wheels of the motor vehicle; a maintenance opening in the underbody surface at the receptacle and being configured for accessing the traction battery for maintenance while the traction battery is attached to the supporting structure of the motor vehicle and disposed in the receptacle; a maintenance cover hingedly attached to the underbody surface along a hinge line substantially adjacent an end of the maintenance opening farthest forward of the rear axle, the maintenance cover having a free end opposite the hinge line and side edges extending between the hinge line and the free end, the maintenance cover being hingedly movable between a closed position where the maintenance cover closes the maintenance opening and an open position where the free end of the maintenance cover is spaced from at least a rear edge of the maintenance opening for accessing the traction battery, locks, on the side edges in proximity to the free end of the maintenance cover and forward of the rear axle for locking the free end of the maintenance cover to the underbody surface; and a diagnosis interface at the underbody surface on the underbody surface of the vehicle in proximity to the maintenance opening and having a wired connection to the traction battery, the diagnosis interface being disposed for access without opening the maintenance cover. - View Dependent Claims (8)
