Electrification of the road transport sector is considered an essential route to reducing carbon dioxide emissions. In recent years, new technology advancements in battery chemistry leading to higher energy density has enabled electrification to be considered for heavy duty road transport. The advent of Megawatt Charging Systems (MCS) marks a significant milestone in the evolution of electric vehicle (EV) infrastructure, enabling the possibility of battery electric trucks to be recharged within a drivers 45-min mandatory break. This would enable battery electric trucks to tackle long haul duty cycles and extend their use cases beyond regional transportation. This paper provides a comprehensive overview of Shell’s development of its MCS charging capabilities, tracing its development timeline and the ongoing efforts towards standardization. Shell’s acquisition of SBRS GmbH led to the opportunity to collaborate and develop megawatt charging solutions which were tested at Shell’s state-of-the-art testing facilities in Hamburg, leading to the deployment of the first publicly accessible megawatt charging system for both onroad and marine applications in Shell’s Energy Transition Centre Amsterdam (ETCA). The collaborative efforts underpinning these initiatives are discussed in detail. Exemplary test case results are presented,offering insights into the performance of MCS under various conditions. The paper concludes with a summary of findings and an outlook on the future of MCS, emphasizing the potential impacts on the EV industry and broader energy ecosystem.
