Foundation for adaptive charging solutions: Optimised use of electric vehicle charging capacity

Abstract As electric vehicles (EVs) are emerging, smart and adaptive charging algorithms have become necessary to ensure safe and efficient operation of the grid. In the scientific literature, most of the proposed charging control algorithms focus solely on EV usage‐related behaviour, while the char...
