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.
