<p>The invention relates to a battery (11) having at least one battery string (20), wherein a plurality of battery modules (30) which can be connected in series and have in each case at least one battery cell are arranged in the battery string (20), wherein said battery string (20) can be activated between the battery string terminals (21, 22) allocated thereto by means of at least one separating device (140) associated with the battery string (20) or said battery string (20) can be decoupled from the battery string terminal (21, 22) allocated to it, and wherein the battery (11) is connectable to an electric motor. The separating device (140) is designed as a bidirectionally lockable switching device, wherein, in the separating device, a semiconductor switch (150) is arranged in the current path of a current flowing through the battery string (20), and the separating device (140) is further designed to switch the current through the battery string (20) independently from its current direction by switching the semiconductor switch (150).</p> |
