Electric vehicles (EVs) are witnessing a remarkable global adoption in all means of vehicle fleet segments, propelled by significant technological development in battery technology and improved EV ranges per charge, which drives a positive shift towards eco-friendly transport modalities. Battery management systems (BMS) ensure electric vehicles operate efficiently, safely, and reliably by overseeing the core controls. In the EV industry, BMS technology is essential for promoting eco-friendly transportation, significantly advancing the movement towards greener travel solutions. Typical roles of BMS, such as state-of-charge and state-of-health assessments, alongside the thermal safety front, spotlight the need for intelligent BMS that harness artificial intelligence. This chapter navigates through the standardization of cybersecurity. Innovations in BMS, machine learning and digital twin technologies, particularly in the vehicular domain, are harbingers of enhanced efficacy and security.
