Abstract
A battery pack for an electric vehicle includes a first battery, a second battery, and a load arranged in parallel. A first semiconductor switching module is arranged in series with the first battery, and 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 to selectively allow current flow from the second battery to the load and from the load to the second battery. A battery control module stores at least one of charge data and usage data corresponding to the first battery and the second battery, and selectively turns on and off the first semiconductor switching module and the second semiconductor switching module based on at least one of the charge data and the usage data.
