According to Sawyer Merritt, a Swedish study conducted by Kvdbil analyzed 1,300 used BEVs and PHEVs to determine which electric vehicles maintain their battery capacity best over time. The results show that the Kia EV6, Kia e-Niro, and Tesla Model Y achieved the highest scores for battery retention. This finding highlights significant advancements in battery management systems and underlines the importance of AI-driven diagnostics and predictive maintenance in the EV sector. For AI companies and automotive tech providers, the study points to new opportunities for developing advanced battery analytics tools and machine learning models to optimize battery performance and lifespan in electric vehicles (source: Teslarati, Sawyer Merritt on Twitter).
