This synthesis study has mapped the state of knowledge regarding battery energy storage systems (BESS) and electric vehicles (EVs) in energy communities, with a particular focus on relevance to Sweden. The study systematically reviewed 218 scientific publications (2016–2025) and combined traditional evidence synthesis with NLP-based text mining, topic modeling, and structured tagging across technical, economic, social, and governance-related dimensions.
The aim has been to identify what works, where knowledge gaps exist, and how Sweden can accelerate the integration of energy storage and electromobility in buildings within flexible energy communities.
The review shows a rapidly growing but uneven research field, with a sharp increase in publications after 2019. Research is primarily focused on the neighborhood scale. Combinations of solar photovoltaics (PV) and batteries dominate, while integrated solutions involving EVs, sector coupling, and real-world performance remain limited.
Sweden is underrepresented in the literature (~4% of the articles), but stands out for its stronger focus on PV/EV integration as well as policy, regulation, and social acceptance—strengths that can be leveraged to move from modeling to real, implementable, and equitable solutions.
