The overall goal of the EARTH project is to identify concepts that will further improve the energy efficiency of wireless access networks. This paper elaborates on radio node level issues addressed by the project. The focus is on radio base station components and radio link concepts to adopt the potential for energy efficiency offered by holistic joint(More)
This paper presents the improvement in fuel consumption which results when the standard diode rectification scheme is compared to synchronous rectification for a standard automotive alternator. These two alternator rectification methods are compared when the alternator is installed in a 'small' vehicle and run over a standard federal urban driving cycle.(More)
It is generally acknowledged that Hardware in the Loop (HIL)/Rapid control prototyping (RCP) is a cost and time effective approach to test controllers/components/subsystems in a system context. Argonne National Laboratory has been using HIL to evaluate the potential of a plug-in hybrid battery in a vehicle (battery hardware in the loop). Argonne has also(More)
Alternative electric motor geometry with potentially increased efficiency is being considered for hybrid electric vehicle applications. An axial flux motor with a dynamically adjustable air gap (i.e., mechanical field weakening) has been tested, analyzed, and modeled for use in a vehicle simulation tool at Argonne National Laboratory. The advantage of(More)
Argonne researchers are revolutionizing the world of combustion engine design with their groundbreaking three-dimensional, high-fidelity combustion engine simulations and visualizations. Award-winning electrolyte additive prevents overcharging by electrochemically " locking in " a maximum voltage. Shown here Som and senior computational scientist Raymond(More)
