Hazard and Risk Analysis on Lithium-based Batteries Oriented to Battery Management System Design

This paper aims to study some of the functional safety standard technical requisites, namely IEC61508 or ISO26262, regarding the Battery Management Systems. A Hazard and Risk Analysis has been carried out to identify the critical aspects of lithium-based batteries, aiming to find the necessary risk reduction and the applicable safety functions with an assigned Safety Integrity Level for a vehicle application.
