Abstract

A power module for a vehicle includes a bidirectional voltage converter to i) convert a first voltage to a second voltage and convert the second voltage back to the first voltage, and ii) convert the first voltage to a third voltage and convert the third voltage back to the first voltage. The power module includes one or more power sources coupled to the bidirectional voltage converter and to supply power to auxiliary components of the vehicle. The power module includes a controller to control the bidirectional voltage converter and the one or more power sources. The first voltage is for supplying power to a powertrain of the vehicle, and the second voltage and the third voltage are for supplying power to the one or more power sources.
