Abstract
A battery pack for an electric vehicle includes a first battery arranged in parallel with a load of the electric vehicle. A second battery is arranged in parallel with the first battery and the load. A first semiconductor switching module is arranged in series with the first battery and is arranged to selectively allow current flow from the first battery to the load and from the load to the first battery. A second semiconductor switching module is arranged in series with the second battery and is arranged to selectively allow current flow from the second battery to the load and from the load to the second battery. A battery control module selectively turns on and off the first semiconductor switching module and the second semiconductor switching module.
