BATTERY SYSTEM AND METHOD

摘要

The invention relates to a battery system, in particular for a motor vehicle, having two voltage-conducting cables, wherein the first cable has a positive potential and the second cable has a potential that is negative thereto, at least two battery modules that each comprise a battery having a positive terminal and a negative terminal, wherein each battery module has a controllable first switching means that is configured to couple the positive terminal of the battery of the respective battery module to the first cable when in a closed state and/or to disconnect the latter when in an open state and to couple the negative terminal of the battery of the respective battery module to the second cable when in an open state and/or to disconnect the latter when in a closed state, and a control means that is configured to control the first switching means of the battery modules in such a manner that only the battery of exactly one battery module is coupled to the voltage-conducting cables. The invention further relates to a method.
