Electric vehicle battery charging strategy

As a key enabler for transportation electrification and a contributor toward the net-zero carbon future, battery plays a pivotal role in determining the energy management performance of electric vehicles. Technical challenges facing the development of advanced automotive battery charging arise from various contradictory objectives, immeasurable internal states, and hard constraints. This chapter presents a critical introduction to the state-of-the-art charging strategies for the electric vehicle battery and their key enabling technologies. Specifically, battery charging solutions for electric vehicles are first classified and discussed. Then, the battery models on which these solutions rest are stated, the related charging frameworks are summarized, and the advantages and drawbacks of the adopted technologies are discussed. Suggestions for overcoming the limitations of the discussed charging strategies are proposed. Moreover, two specific case studies of designing advanced battery charging solutions to benefit battery health management and battery thermal management are presented and discussed. This chapter will inform academic research agendas alike and technology choices, thus boosting progress in the optimal battery charging design to benefit electric vehicle fast charging, health-conscious charging, and efficient thermal and energy management-based charging.
