Abstract
The invention relates to a battery system (), comprising a battery module (), which comprises a first high-voltage connection (), a second high-voltage connection () and a multiplicity of battery cell modules () which are connected in series between the first and second high-voltage connections, and a switching matrix (). The switching matrix comprises a large number of switching rails (), which are each connected to one of the nodes between in each case two of the battery cell modules which are connected in series, a multiplicity of first switching devices (), which are designed to connect in each case one of the switching rails () to a first low-voltage connection () of the switching matrix (), and a multiplicity of second switching devices (), which are designed to connect in each case one of the switching rails () to a second low-voltage connection () of the switching matrix. In this case, a first total voltage (HV) of all of the battery cell modules () which are connected in series is present between the first high-voltage connection () and the second high-voltage connection (), and a second total voltage (LV) of some of the battery cell modules () which are connected in series is present between the first low-voltage connection () and the second low-voltage connection (), depending on the switching state of the first switching devices () and the second switching devices ().
