Are rechargeable energy storage systems safe in electric vehicles?

Published studies on road vehicles have not adequately considered the safety assurance of rechargeable energy storage systems in accordance with ISO 26262 standard. Accordingly in this paper, we focus on the safety assurance of a battery management system (BMS) that prevents thermal runaway and keeps lithium-ion batteries safe in electric vehicles.

What are the requirements of a rechargeable energy storage system?

Part II: Requirements of a Rechargeable Energy Storage System (REESS) with regard to its safety No restriction to high voltage batteries, but excluding batteries for starting the engine, lighting,. Amend an annex with test procedures 7 Kellermann/24.05.2012/GRSP Requirements in Part II

What is a rechargeable energy storage system (RESS) test?

It describes a body of tests which may be used as needed for abuse testing of electric or hybrid electric vehicle Rechargeable Energy Storage Systems (RESS) to determine the response of such electrical energy storage and control systems to conditions or events which are beyond their normal operating range.

How are hazard and operability analyses used in automotive rechargeable energy storage systems?

ABSTRACT Two approaches, Hazard and Operability Analysis and System Theoretic Process Analysis, were used to evaluate hazards associated with automotive rechargeable energy storage systems (RESSs). The analyses began with the construction of an appropriate block diagram of RESS functions and the identification of potential malfunctions.

What happens when a rechargeable energy storage system dies?

In general, rechargeable energy storage systems (RESS) exhibit a progressive capacity fade until the remaining capacity is too low for the specific application and the RESS thereby reaches its end of life. Under certain circumstances though, safety-relevant events can occur during operation or storage.

What are the safety requirements for electrical energy storage systems?

Electrical energy storage (EES) systems - Part 5-3. Safety requirements for electrochemical based EES systems considering initially non-anticipated modifications, partial replacement, changing application, relocation and loading reused battery.
