Journal ArticleDOI
Lithium iron phosphate based battery: Assessment of the aging parameters and development of cycle life model
Noshin Omar,Noshin Omar,Mohamed Abdel Monem,Mohamed Abdel Monem,Yousef Firouz,Justin Salminen,Jelle Smekens,Omar Hegazy,Hamid Gaulous,Grietus Mulder,Peter Van Den Bossche,Thierry Coosemans,Joeri Van Mierlo +12 more
TL;DR: In this article, the impact of the working temperature on the battery performance over its lifetime was analyzed and a cycle life model was developed to predict the battery cycleability accurately, which revealed that the cycle life of the battery degrades the more the charge current rate increases.
Journal ArticleDOI
Analysis, Modeling, and Implementation of a Multidevice Interleaved DC/DC Converter for Fuel Cell Hybrid Electric Vehicles
TL;DR: In this paper, a multidevice structure with interleaved control is proposed to reduce the input current ripples, the output voltage ripples and the size of passive components with high efficiency compared with the other topologies.
Journal ArticleDOI
Thorough state-of-the-art analysis of electric and hybrid vehicle powertrains: Topologies and integrated energy management strategies
Dai-Duong Tran,Majid Vafaeipour,Mohamed El Baghdadi,Ricardo Barrero,Joeri Van Mierlo,Omar Hegazy +5 more
TL;DR: Various powertrain systems and topologies of (plug-in) hybrid electric vehicles and full-electric vehicles are assessed and EMSs as applied in the literature are systematically surveyed for a qualitative investigation, classification, and comparison through a comprehensive review.
Journal ArticleDOI
DC-DC Converter Topologies for Electric Vehicles, Plug-in Hybrid Electric Vehicles and Fast Charging Stations: State of the Art and Future Trends
Sajib Chakraborty,Hai-Nam Vu,Mohammed Mahedi Hasan,Dai-Duong Tran,Mohamed El Baghdadi,Omar Hegazy +5 more
TL;DR: In this article, the design and evaluation of different DC-DC converter topologies for battery electric vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) are presented, analyzed and compared in terms of output power, component count, switching frequency, losses, effectiveness, reliability and cost.
Journal ArticleDOI
Rechargeable Energy Storage Systems for Plug-in Hybrid Electric Vehicles—Assessment of Electrical Characteristics
Noshin Omar,Mohamed Ali Abdelfattah Hamoda Daowd,Peter Van Den Bossche,Omar Hegazy,Jelle Smekens,Thierry Coosemans,Joeri Van Mierlo +6 more
TL;DR: In this paper, the performances of various lithium-ion chemistries for use in plug-in hybrid electric vehicles have been investigated and compared to several other rechargeable energy storage systems technologies such as lead-acid, nickel-metal hydride and electrical double layer capacitors.
