Abstract
A battery system may include a plurality of battery modules connected in series. A battery module of the plurality of battery modules may include a cell stack array, a first solid state switch and a second solid state switch arranged in a half bridge configuration and configured to operate in a complementary fashion, and a solid state driver connected to both gates of the first solid state switch and second solid state switch and configured to turn on and off the first solid state switch and the second solid state switch. Further, the cell stack array is configured to be active when the first solid state switch is on and the second solid state switch is off, and configured to be bypassed when the first solid state switch is off and the second solid state switch is on.
