PV-grid integrated multifunctional buck-boost on-board EV charger with CCM-DCM operation Universiteit Gent

Homayoun Soltani Gohari, Hadi Tarzamni, Peter Sergeant, Hendrik Vansompel
This paper delves into the development of on-board EV chargers with the purpose of using the energy of the vehicle-roof photovoltaic panels and merging charging and driving modes power converters. In pursuit of this objective, a novel high step-up coupled inductor-based DC-DC converter is proposed, which enables the proposed charger to use the PV panel energy in an efficient way. From utility grid point of view, a bridgeless AC-DC converter is ...

Assessing the Impact of EV Charging and Discharging Profiles on T-Type Active Front End Charger Lifetime Vrije Universiteit Brussel

Hakan Polat, Farzad Hosseinabadi, Sajib Chakraborty, Thomas Geury, Mohamed El Baghdadi, Omar Hegazy
This paper aims to assess the lifetime of a T-type active front end (AFE) converter in the context of Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) applications providing various grid services. To achieve this goal, the research paper presents two G2V and three V2G profiles and measures the junction temperature oscillations
for the entire mission profile. Then, the temperature profiles are imported into a reliability assessment model to ...

Load Balancing with EV chargers and PV inverters in Unbalanced Distribution Grids KU Leuven

Sam Weckx, Johan Driesen
© 2010-2012 IEEE. Balanced three-phase four-wire distribution grids can host significantly more distributed generation and electric vehicles. Three-phase photovoltaic (PV) inverters and electric vehicle (EV) chargers can be adapted to transfer power from highly loaded to less loaded phases, without overloading the inverter or charger. Grid conditions will be improved due to a more balanced operation of the network and more PV panels and EVs can ...

Bidirectional single-phase integrated on-board charger for ultracapacitor-battery based EVs with V2G and regenerative braking capability Universiteit Gent

Homayoun Soltani Gohari, Peter Sergeant, Lynn Verkroost, Hendrik Vansompel
This paper develops the EV powertrains by introducing a multiport multifunctional integrated charger designed for single-phase systems. As an integrated on-board charger, this system utilizes the stator windings of the Permanent Magnet Synchronous Motor (PMSM) as the rectifier filter. Four distinct winding configurations are employed to achieve torque cancellation during the charging mode. These configurations are elucidated and comprehensively ...
