      abstract = {Increasing concerns with the use of petroleum and the increasing regulations on fuel economy, electric powertrains have become more acceptable to automotive manufacturers. The Lithium-Ion batteries employed in such systems are typically managed by a High Voltage (HV) Battery Management System (BMS). Due to the presence of HV battery, the hazards involved in the Electric Vehicle (EV) such as Electric Shock, Thermal Event and Toxic Gas release are typical hazards. Therefore, functional safety plays a crucial role in designing safe BMS and mitigating hazards in EVs. The ISO 26262:2018 standard provides a framework for developing and validating automotive products to ensure they are free from electrical and electronic malfunctions. This paper introduces options for BMS system development in accordance with ISO 26262. Hazards and risks associated with BMS malfunctions identified and classified according to the standard. A concept BMS system is developed according to ISO 26262 methodologies, including item definition, hazard analysis and risk assessment, safety goal derivation and functional safety concept. Generic HV battery system architecture developed and discussed, with conclusions drawn based on the design and EV application.},
