Statistical Characterisation of Public AC EV Chargers in the UK

In recent years, the public AC electric vehicle (EV) charging network in United Kingdom (UK) has experienced significant growth, more than doubling size. However, there remains a lack of information regarding usage patterns, which hampers decision-making for future infrastructure planning. This study addresses this gap by presenting statistical analysis based on data from nearly twelve thousand EV sessions. The was collected 595 sockets, with 85% operating at 7 kW and remaining 15% 22 kW, throughout UK between April 2022 July 2022. focuses key factors that define primary characteristics current ecosystem, including utilisation rates, arrival-departure times, sojourn durations, energy transfer, overstay durations. Several important observations are made, such as variability influencing periods, peak demand periods. With two case studies, potential role smart leveraging flexibility is shown lowering shifting loads. findings have implications planning efficient allocation investments to expand infrastructure. By gaining better understanding informed decisions can be made optimize expansion facilities.
