摘要:
The present invention relates to a battery system which has a hybrid battery which comprises a first energy storage source having a plurality of first energy storage cells and comprises a second energy storage source which is connected in series with the first energy storage source and has a plurality of second energy storage cells which are different from the first energy storage cells. Furthermore, the battery system has an inverter which is connected at the input end to the battery and is designed to convert a DC voltage which is supplied to the input end into an, in particular polyphase, AC voltage which is produced at the output end. The battery system also has a control unit which is designed to operate the inverter in a first functional mode or in a second functional mode or in a third functional mode by controlling a plurality of semiconductor switches of the inverter. In the first functional mode, the inverter converts a DC voltage which is provided by the first energy storage source and is supplied to the input end into the AC voltage which is produced at the output end. In the second functional mode, the inverter converts a DC voltage which is provided by the second energy storage source and is supplied to the input end into the AC voltage which is produced at the output end. In the third functional mode, the inverter converts a DC voltage which is provided by a series circuit comprising the first energy storage source and the second energy storage source and is supplied at the input end into the AC voltage which is produced at the output end.
