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

Abstract

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.
