Abstract
A power converter for an electric vehicle include a connection interface for coupling an external battery to a first bus. The power converter includes a first set of switching devices configured to transfer power between a charge port and the first bus, and a second set of switching devices configured to transfer power between the first bus and a second bus coupled to a traction battery. The power converter includes a controller programmed to control a voltage level of the first bus to different nominal operating voltages based in different operating modes.
