   Diverse battery chemistries and designs involve exploring various materials and configurations beyond traditional lithium-ion technologies. Research into new chemistries such as sodium-ion and lithium-sulfur batteries offers advantages like lower costs and increased performance. A report by Artorg Center for Biomedical Engineering Research in 2022 discusses how these alternatives can enhance energy storage capabilities in electric vehicles.

7. Regulatory Impacts and Incentives:
   Regulatory impacts and incentives drive the adoption of electric vehicles and battery technologies. Governments worldwide are implementing policies to promote EV usage and set emissions targets. For example, the European Union has introduced stricter emission standards, stimulating car manufacturers to invest in cleaner technologies. A report by the International Council on Clean Transportation in 2022 indicates that regulatory support can accelerate the transition to EVs by up to 10 years.

In summary, the future of auto EV battery systems is shaped by enhanced technology, reductions in costs, increased sustainability efforts, expanded charging infrastructure, advancements in battery storage systems, exploration of diverse chemistries, and the influence of regulatory measures.
