An electric truck has a chassis, on which a driver's cab with a motor compartment containing an electric motor is disposed in the front of the electric truck, and in the rear a cargo body rests on the chassis. The cargo body substructure sits on vehicle longitudinal beams of the chassis. The cargo body bottom sealing the cargo body on the underside is spaced above the vehicle longitudinal beams to ensure clearance for a sufficient spring travel. A battery housing with at least one integrated battery is disposed in the intermediate space between the vehicle longitudinal beams and the body bottom, so that a larger installation space is available for the batteries and therefore a greater range for the electric truck. The battery is protected in this region and, moreover, the insulation of the battery housing simultaneously contributes to insulation of the cargo body disposed above the battery housing.

Electric truck

A method for producing a battery housing produces intermediate products, including a lower and upper half-shell, for connecting these intermediate products with one another at the facility of a battery manufacturer. The battery is set into the lower half-shell, the upper half-shell is set on, the inner wall of the lower half-shell is welded to the inner wall of the upper half-shell, and the outer wall of the lower half-shell is welded to the outer wall of the upper half-shell, with a supported vacuum insulation interposed between the inner and outer walls of the lower and upper half-shell, respectively, to form a reversibly closed battery housing with integrated thermal management for a battery. An assembly kit may be delivered to a battery manufacturer for non-problematical production of a battery housing at the facility of the battery manufacturer to eliminate transport of the battery to the battery housing manufacturer.

Method for the production of a battery housing

A battery housing for accommodating one or more cell blocks of a battery provides the interstice between an outer wall and an inner wall with supported vacuum insulation composed of a porous support material. This vacuum insulation can be switched between an insulation state and a transient state. The interstice is additionally provided with cooling elements. This battery housing offers crash-safe accommodation of the cell blocks accommodated in the battery housing, for one thing, and furthermore offers passive or controllable and/or regulatable thermal management to the effect that the cell blocks accommodated in the battery housing can be cooled or heated as needed, in any case kept in a permissible temperature range in every operating state.

Battery housing

Proceeding from a state of the art from which double-walled insulation housings that are provided with supported vacuum insulation are already known, the invention proposes an improved insulation housing that is characterized in that first, a planar surface element () is produced, in which the wall elements () of the insulation housing, which are connected with one another, are connected with one another by means of a transition region, which region has a notch (), wherein it is made possible, in this way, to produce the three-dimensional spatial shape of the insulation housing only in a last production step, by means of corresponding folding and setting upright of the wall elements () that are connected with one another, and subsequently to fix the wall elements () in place in this spatial shape, in accordance with the intended purpose.
