Definitions
- the present invention relates to a chassis of a vehicle and a vehicle.
- Chassis usually form the supporting element of a vehicle, such as a passenger car. In the field of passenger cars, self-supporting bodies are also known as supporting elements of the vehicle.
- the chassis has the function of carrying a drive, one or more motors, add-on parts, and a payload of the vehicle.
- a battery is usually provided as an electrical energy store, which supplies the motor or the motors with electrical energy.

- chassis with battery arrangements can be provided with the largest possible volume, which allows high battery capacities.
- the mechanical integration of the battery arrangement as a supporting element of the chassis also offers the advantage that a particularly lightweight construction of the chassis can be made possible, since, for example, a proportion of frame or support elements or the like, which only contribute to the mechanical stability of the chassis, can be significantly reduced.

- the battery arrangement is particularly preferably designed as a one-piece battery module. This means that the battery arrangement forms a defined component designed as a single mechanically integrated unit. This allows for a particularly low weight of the chassis and an optimal use of space, for example for the battery cells.

- the components that can be arranged in the receiving space can be protected by the battery arrangement that at least partially surrounds them.
- the receiving space is particularly preferably completely enclosed by the battery arrangement in at least one plane.

- the chassis further includes a cooling system.
- the cooling system has a common cooling circuit for the battery arrangement and for at least one component accommodated in the receiving space.
- a cooling device for cooling the component is particularly advantageously designed as part of a cooling device for the battery arrangement, that is to say it is integrated into the cooling system of the battery arrangement.
- a particularly efficient cooling system can be provided, since, for example, a flow path that a cooling liquid has to cover to cool the battery module and/or component can be reduced in order to provide a low pressure drop, for example.
- the chassis preferably also includes an electric motor which is arranged, in particular at least partially, in the receiving space.
- an electric motor which is arranged, in particular at least partially, in the receiving space.
- the electric motor is particularly preferably integrated into the common cooling circuit of the battery arrangement. Cooling of the electric motor is preferably in the form of jacket cooling, with a cooling liquid flowing through the stator housing. In this case, for example, part of the battery arrangement can form a housing around the stator and form a channel wall for the coolant flow.
- the chassis preferably also includes power electronics which are integrated into the battery arrangement.

Because the electrical lines are arranged within the battery arrangement, which is preferably designed as a single, in particular rigid, component, flexibility and/or complex insulation of the lines can be dispensed with, as a result of which a particularly simple, cost-effective and lightweight construction is provided can.
- the chassis preferably also includes a number of connection elements on the battery arrangement, which are set up for connection to a body and/or to chassis components and/or to add-on parts.
- the connecting elements can be formed integrally, ie preferably in one piece, with the battery housing and form attachment points for other elements of a vehicle. A particularly advantageous mechanical integration of the battery arrangement into the chassis of the vehicle can thereby be achieved.
- the chassis also includes at least one or more of the following components: drive train, chassis components, steering, wheels.
- drive train chassis components
- steering wheels

- Figure 1 is a simplified schematic view of a vehicle with a chassis according to a first embodiment of the invention
- FIG. 2 is a simplified schematic view of the chassis of
- FIG. 1 is an alternative detailed view of the chassis of Figure 1
- FIG 4 is another alternative view of the chassis of Figure 1, and
- FIG. 5 shows a simplified schematic view of a chassis according to a second embodiment of the invention.
- FIG. 1 shows a simplified schematic perspective view of a vehicle 10 with a chassis 1 according to a first embodiment of the invention.
- the chassis 1 is also shown in more detail in FIG. Further detailed views of the chassis 1 of the first exemplary embodiment are shown in FIGS. 3 and 4.

- the vehicle 10 can thus only be driven with an electric drive.
- the drive of the vehicle 10 is integrated into the chassis 1 .
- the chassis 1 includes two electric motors 6 (see FIG. 2), which are provided as drive motors of the vehicle 10 .
- one of the two electric motors 6 is arranged on a front axle 3 and on a rear axle 4 of the chassis 1 .

- electrical lines that can be produced easily and inexpensively, such as rigid copper lines, can be used, which do not have to be flexible and do not have to be protected and insulated against environmental influences in a complex manner.
- the path of the electrical energy transmission can thus be designed in a particularly simple and cost-effective and lightweight manner.

- the battery arrangement 2 in the second exemplary embodiment comprises two second battery modules 24, 25.
- the two second battery modules 24, 25 are arranged directly adjacent to the first battery module 23 on both sides in the longitudinal direction 15 of the chassis. This means that one of the two axes 3, 4 runs through one of the two second battery modules 24, 25.
- the battery modules 23, 24, 25 are each connected to one another by means of a connection interface 26.
- the connection interface 26 is located in particular in a contact area between the respective battery modules 23, 24, 25.
- the connection interface 26 is designed in such a way to jointly establish a mechanical connection and an electrical connection and a coolant connection of the battery modules 23, 24, 25.
- the mechanical connection can be made by screwing and/or welding the battery modules 23, 24, 25.
- a modular structure of the battery arrangement 2 can be provided.
