Abdeldayem, O.M.H.M. (author), Dupont, Capucine (author), Ferras, David (author), Ndiaye, Lat Grand (author), Kennedy, M.D. (author)

Although industrial hydrothermal carbonization (HTC) uses wet feedstock, lab-scale studies tend to dry the feedstock under the assumption that the rehydration of the feedstock would restore its original properties. To the best of our knowledge, this assumption has not been thoroughly examined at the lab scale; therefore, its investigation is...

A Comprehensive Review on Off-Grid and Hybrid Charging Systems for Electric Vehicles

Rituraj, G. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)

In recent years, the research interest in off-grid (standalone mode) and hybrid (capable of both standalone and grid-connected modes) charging systems for electric vehicles (EVs) has increased. The main reason is to provide a seamless charging infrastructure in urban and rural areas where the electrical grid is unreliable or unavailable so that...
