Device in the form of an electrically operated vehicle, in particular an electrically operated commercial vehicle such as an industrial truck or forklift truck, which receives at least one power supply module (20; 120) containing at least one electrical power source and/or at least one chargeable electrical power accumulator in at least one receiving space (6; 100) in a module-receiving structure of the vehicle in order to provide electrical power for operating the vehicle, it being possible for the power supply module (20; 120) to be introduced into the receiving space (6; 100) along an insertion path from an introduction side in relation to the module-receiving structure, to be positioned in a defined operating position and to be removed from the receiving space (6; 100) towards the introduction side, and, in the operating position, a first electrical contact assembly (7; 107) of the module-receiving structure engaging or being able to be brought into engagement with a second electrical contact assembly (21; 121) of the power supply module (20; 120) in order to connect a first electrical conductor assembly that is connected to the first contact assembly to a second electrical conductor assembly that is connected to the second electrical contact assembly, the module-receiving structure comprising inner surfaces (9, 10, 11, 12, 19, 19a, 13, 14, 14a) which define the receiving space (6; 100) and are opposite associated outer surfaces of the power supply module arranged in the operating position, the module-receiving structure comprising first guide means (10, 12, 16; 103) in the receiving space (6; 100) that interact with second guide means (22; 24, 25; 26; 27; 122, 123, 124, 125) of the power supply module in the operating position in relation to the positioning of the power supply module when the power supply module is introduced into the receiving space, and the power supply module (20; 120) being positioned and oriented in a defined manner relative to the module-receiving structure and thus in the receiving space (6; 100) in a translational manner in relation to all three mutually orthogonal spatial directions and in a rotational manner in relation to an inclination about three mutually orthogonal axes of inclination, such that the power supply module, when in the operating position, can be moved away from the operating position in a predefined movement direction, which is determined by the design of the module-receiving structure and the power supply module and is referred to in the following as the reference direction, for the purpose of being removed from the receiving space, at least at the start of the movement of the power supply module; characterised in that the module-receiving structure and the power supply module (20; 120) are configured relative to one another such that the power supply module, when being introduced into the receiving space (6; 100), initially, after an end of the power supply module that is at the front in an insertion direction is inserted into the receiving space or an introduction channel of the module-receiving structure leading to said space, has a defined relative translational movement clearance in two spatial directions that are orthogonal to one another and to the insertion direction and a relative rotational movement clearance about three mutually orthogonal axes of inclination relative to the module-receiving structure, the relative translational movement clearance and the relative rotational movement clearance being increasingly reduced as the power supply module (20; 120) is introduced further into the receiving space (6; 100), until, no later than when said module reaches the operating position, the relative translational movement clearance and the relative rotational movement clearance disappear or are reduced to a minimal relative residual movement clearance.
