Abstract
Compliance of electric vehicle (EV) Battery Management Systems (BMS) with func-tional safety standard ISO 26262 is considered mandatory due to several risks associated with Lithium-Ion (Li-ion) batteries (BT). However, the high-criticality safety goals formed in accordance with the standard can significantly increase the implementation and verification complexity of the EV-BMS. Therefore, the aim of this paper is to propose an improved safety architecture which can provide effective mechanisms to prevent or mit-igate both systematic and random faults and avoid single instances of failure. This archi-tecture is applicable to a wide range of EV BT topologies and therefore, it can simplify and accelerate the development lifecycle of modern EVs.
