This paper introduces an adaptive multiresolution framework for electric vehicle (EV) energy consumption estimation with real-time capability. Three key parameters, namely powertrain efficiency, wind speed, and rolling resistance, are adaptively estimated using a two-step nonlinear iterative algorithm. Based on this algorithm, multichannel high-resolution efficiency is introduced. Employing the "connected vehicles" concept, more reliable trip level estimates achieved by sharing sensed...
