A novel hybrid PI–backstepping cascade controller for battery–supercapacitor electric vehicles considering various driving cycles scenarios

IET Power Electronics, Volume 17, Issue 9, Page 1089-1105, 24 July 2024.
This paper introduces a novel hybrid cascade control, combining a proportional–integral controller with a backstepping nonlinear controller, designed for bi‐directional DC–DC converters. It aims to regulate the DC bus voltage and control the currents of onboarded battery and supercapacitor sources, especially under conditions of uncertainty and high ...

Real‐time monitoring and ageing detection algorithm design with application on SiC‐based automotive power drive system

IET Power Electronics, Volume 17, Issue 6, Page 690-710, 6 May 2024.
Electro‐thermal real‐time modeling of an electric drive for new generation electric vehicles. The real‐time model is validated against experimental measurements obtained during a WLTP cycle. Real‐time modeling makes it possible to develop and validate with a PIL approach an algorithm for monitoring the aging effects of the active components of the ...

Auxiliaries’ power and energy demand prediction of battery electric vehicles using system identification and deep learning

IET Intelligent Transport Systems, Volume 18, Issue 4, Page 743-754, April 2024.
The energy demand of the auxiliaries of battery electric vehicles can account for a significant share of the total energy demand of a trip and must be taken into account for the prediction of the vehicle's remaining driving range. To this end, this paper investigates a method that estimates the power requirements of the auxiliaries depending on ...

Dynamic CO₂ Emission Differences Between E10 and E85 Fuels Based on Speed–Acceleration Mapping

Energies
This study compared CO2 emissions during a WLTP (Worldwide Harmonized Light-Duty Vehicles Test Procedure) test performed on a chassis dynamometer for the same flex-fuel vehicle, fuelled sequentially with E10 gasoline and E85 fuel. Based on the test data,

Electric vehicle charging as a source of nordic fast frequency reserve—proof of concept

IET Generation, Transmission &Distribution, Volume 18, Issue 6, Page 1223-1234, March 2024.
This article proposes and demonstrates that a home charger can participate in this extremely fast reacting ancillary service market with only software modifications made to the charger. A laboratory test setup was constructed to test the capabilities of the Fast Frequency Reserve (FFR)‐enabled electric vehicle charger to provide FFR‐qualifying capacity
