ELECTRIC POWER SYSTEM FOR AN AUTONOMOUS VEHICLE

An electric power system includes an energy recovery system that is operable to convert kinetic energy into electric energy at a first voltage. A primary energy storage device is electrically connected to the energy recovery system at the first voltage. A first voltage autonomous driving system load is disposed in a parallel circuit with the energy recovery system and the primary energy storage device. A bi-directional DC-DC converter is electrically connected to the energy recovery system and the primary energy storage device for converting the electric energy between the first voltage and a second voltage. A secondary energy storage device is electrically connected to the bi-directional DC-DC converter at the second voltage. A second voltage autonomous driving system load is disposed in a parallel circuit with the secondary energy storage device.
