Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. The OSU EcoCAR PHEV powertrain. This value represents the upper limit for waste heat recovery systems to convert thermal energy from the exhaust gases into mechanical energy. Power from ORC.

Audi introduces Q5 55 TFSI e quattro plug-in hybrid; first of new PHEVs

Green Car Congress

The climate control system uses a heat pump that pools the waste heat from the high-voltage components. Depending on the situation, the system chooses predictively between freewheeling with the engine switched off and coasting recuperation, i.e. the recovery of kinetic energy and its conversion into electrical energy.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. The lowest WTW energy demand and GHG emissions were achieved using electricity from waste incineration, biogas CHP, hydropower, wind power, and photovoltaic power.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

Because the use of natural gas for transportation requires compressing, liquefying, or conversion, it is important to determine the best use of natural gas as a transportation fuel. For the PHEV cases, both charging from the US mix and charging from a natural gas turbine with a 45% electrical generating efficiency were considered.

Audi highlights its range of electrification efforts; Q7 diesel PHEV, A7 fuel cell PHEV, BEV, 48V and more; 750 Wh/l by 2025

Green Car Congress

This makes it possible for the waste heat from the electrical drive components to be made available to the interior of the Q7 e-tron quattro. The Q7 PHEV will arrive in dealerships in Germany in 2016, and will likely come to the US, although perhaps with a gasoline-engine variant. Audi e-tron quattro concept SUV.
