Ashish Arora and Sneha Lele
This tutorial will provide an overview of the requirements and challenges of designing large format Li-ion battery systems such as those used in electric vehicles, grid storage applications etc. Functional safety concepts commonly used when designing these battery systems will be introduced and the hazards associated with large format battery systems will be explained using case studies. The tutorial will also provide an overview of applicable industry standards, examples of common large format battery system architectures and their advantages and disadvantages and the typical failure modes of protection schemes commonly used for large format battery systems.
