BATTERY CELL HAVING INCREASED RELIABILITY AND TRACTION BATTERY EQUIPPED THEREWITH

摘要

The invention relates to a battery cell (1) having an energy store (3) connected to a first battery pole (4) and a second battery pole (5). According to the invention, the battery cell (1) has at least one disconnect device (2a), wherein the at least one disconnect device (2a) brings about an interruption of the connection of the energy store (3) to the first battery pole (4) and/or the second battery pole (5) when correspondingly actuated, and a bridge device (2b) connected between the first battery pole (4) and the second battery pole (5), wherein the first battery pole (4) and the second battery pole (5) can be short-circuited by means of the bridge device when actuated correspondingly. The invention further relates to a battery, in particular a traction battery, having a series circuit of battery cells (6), of which at least one battery cell (1) is a battery cell (1) according to the invention.
