Research supported by the Office of Naval Research and conducted by HNEI researchers, led by Matthieu Dubarry, is a feature paper invited by editorial office of Batteries in the Special Issue on Batteries and Supercapacitors Aging.  This research paper "Synthetic vs. Real Driving Cycles: A Comparison of Electric Vehicle Battery Degradation" is included in the journal's June 2018 issue and is available at https://dx.doi.org/10.3390/batteries5020042.

Automobile dependency and the inexorable proliferation of electric vehicles compels accurate predictions of cycle life across multiple usage conditions and for multiple lithium-ion battery systems.  Synthetic driving cycles have been essential in accumulating data on EV battery lifetimes.  However, since battery deterioration is path-dependent, the representability of synthetic cycles must be questioned.  Hence, this work compared three different synthetic driving cycles to real driving data in terms of mimicking actual EV battery degradation.
