Abstract

A vehicle comprising a vehicle body (2) and a battery (3) with energy storage devices (31) and a housing (32), which at least partially surrounds the energy storage devices (31), wherein a vehicle-body region (21) of the vehicle body (2) forms a part of the housing of the battery (3), wherein the vehicle-body region (21) is made from an electrically conductive material or comprises electrically conductive material in order to shield the vehicle against electrical and/or magnetic fields.

Claims

1. A vehicle, comprising:

a vehicle body (2); and

a battery (3) with energy storage devices (31) and a housing (32), which at least partially surrounds the energy storage devices (31),

wherein a shielding vehicle-body region (21) of the vehicle body (2) forms a part of the housing of the battery (3), and

wherein the shielding vehicle-body region (21) is made from an electrically conductive material or comprises electrically conductive material in order to shield the vehicle against electrical and/or magnetic fields.

2. The vehicle according to claim 1, characterized in that the shielding vehicle-body region (21) forms a cover of the housing.

3. The vehicle according to claim 1, characterized in that the shielding vehicle-body region (21) forms a base of the housing.

4. The vehicle according to claim 1, characterized in that the shielding vehicle-body region forms walls (24, 25, 26) of the housing.

5. The vehicle according to claim 1, characterized in that the shielding vehicle-body region (21) is a part of an underbody (20) of the vehicle.

6. The vehicle according to claim 1, characterized in that the vehicle body (2) has a recess (22) in which the energy storage devices (31) are at least partially arranged.

7. The vehicle according to claim 1, characterized in that the housing of the battery (3) comprises an electrically conductive material for shielding against electrical and/or magnetic fields of the energy storage device (31).

8. The vehicle according to claim 1, characterized in that a circumferentially closed, electrically conductive connection (4) is formed between the shielding vehicle-body region (21) and the housing (32) of the battery.

9. The vehicle according to claim 8, characterized in that the connection (4) is a low-impedance connection.

10. The vehicle according to claim 8, characterized in that the connection (4) between the shielding vehicle-body region (21) and the housing (32) includes metal resilient contacts.

11. The vehicle according to claim 1, also comprising an inverter (5), which is connected to the battery (3), wherein the inverter (5) is at least partially shielded by the shielding vehicle-body region (21).

12. The vehicle according to claim 1, characterized in that the vehicle body (2) has a recess (22) in which the energy storage devices (31) are completely arranged.

13. The vehicle according to claim 8, characterized in that a cohesive connection is provided between the shielding vehicle-body region (21) and the housing (32).
