Abstract
A battery includes a first terminal, a second terminal, a first battery module, a second battery module, and a third batter module. The first battery module and the second battery module includes a first pole, a second pole, a plurality of battery cells, a charge and disconnect device, a disconnect device, and a bridging device. The third battery module includes a first pole, a second pole, a plurality of battery cells, a first disconnect device, a second disconnect device, and a bridging device. The first and second poles of the first battery module are connected in series with the first terminal and the first pole of the third battery module. The first and second poles of the second battery module are connected in series with the second terminal and the
second pole of the third batter module.
