First Claim
1. A battery, in particular a traction battery, having:
- a first battery cell group and a second battery cell group, each cell group including a plurality of battery cells, in whicha first terminal of the first battery cell group is connected to a first battery pole via a charging and disconnecting device,a second terminal of the first battery cell group is connected to a first surface plug connection,a first terminal of the second battery cell group is connected to a second surface plug connection,a second terminal of the second battery cell group is connected to a second battery pole via a charging and disconnecting device, andthe first surface plug connection and the second surface plug connection can be short-circuited via an external surface plug; and
a first jumper device, which is connected between the first battery pole and the first surface plug connection, by way of which jumper device the first battery pole and the first surface plug connection can be short-circuited; and
a second jumper device, which is connected between the second battery pole and the second surface plug connection, by way of which jumper device the second battery pole and the second surface plug connection can be short-circuited,wherein the charging and disconnecting devices associated with the first and second terminals are separate from each other and each includes a separate charger connected in parallel to a corresponding disconnecting device.

Abstract
The invention relates to a traction battery having a first battery cell group and a second battery cell group. A first connection of the first battery cell group is connected to a first battery pole by a charging and disconnecting device, a second connection of the first battery cell group is connected to a first service plug connection, a first connection of the second battery cell group is connected to a second service plug connection, and a second connection of the second battery cell group is connected to a second battery pole by a disconnecting device. The first service plug connection and the second service plug connection can be short-circuited by an external service plug. According to the invention, such a traction battery comprises a first jumper connected between the first battery pole and the first service plug connection, by means of which the first battery pole and the first service plug connection can be short-circuited, and/or a second jumper device connected between the second battery pole and the second service plug connection, by means of which the second battery pole and the second service plug connection can be short-circuited.
