Integrated waste heat recovery and motor assisted turbocharger system

A method for assisting a turbocharger system using waste heat energy, the method comprising the steps of:

• heating a fluid with at least one of a power electronics cold plate, engine coolant, an engine, a boiler, and a recuperator;
• cooling the fluid using a condenser;
• operating a first power transmission device and a second power transmission device, wherein the first power transmission device connected on a first side to a turbine, and a drive gear disposed about and connected to a second side of the first power transmission device, the second power transmission device connected on a first side to a side of the drive gear opposite the first power transmission device;
• a compressor connected to a second side of the second power transmission device;
• engaging the first power transmission device;
• driving the turbine using engine exhaust gas such that the turbine drives at least one of the compressor and a motor generator.
