Survey of power management control technologies for HEVs and PHEVs suggests future need to consider vehicle as part of larger system

April 11, 2014

A comprehensive survey of major power management control algorithms for hybrid-electric (HEVs) and plug-in hybrid electric vehicles (PHEVs) proposes that future work will need to consider the vehicle as part of a larger system which can be optimized at an even larger scale.

This type of large-scale optimization will require the acquisition and processing of additional information from the driver and conditions outside the vehicle itself, suggests Dr. Andreas Malikopoulos, Deputy Director of the Urban Dynamics Institute and an Alvin M. Weinberg Fellow in the Energy and Transportation Science Division with Oak Ridge National Laboratory (ORNL).

Mercedes-Benz’s new generation flagship S-Class, introduced at an elaborate event at Airbus in Finkenwerder, marks a number of technology firsts in numerous areas from comfort, to driver control, to efficiency. As one example of the last, the new S-Class is the first car in the world to completely dispense with conventional electric bulbs, making exclusive use of energy-saving LED technology both inside and outside.

On a larger efficiency scale, the new S-Class in its first year will offer two hybrid versions, a gasoline model and a diesel variant: the S 400 HYBRID, S 300 BlueTEC HYBRID, S 500, and S 350 BlueTEC. The models offer up to 20% lower fuel consumption than the outgoing model series. These soon will be followed by the S 500 Plug-In HYBRID—the first S-Class with a fuel consumption lower than 4l/100 km (59 mpg US). All the engines already meet the requirements of the Euro-6 emissions standard.
