Safety Management of Automotive Rechargeable Energy Storage Systems: The Application of Functional Safety Principles to Generic Rechargeable Energy Storage Systems

This report documents two NHTSA approaches evaluating hazards associated with automotive rechargeable energy storage systems (RESS).  It consists of four parts: (1) evaluating hazards with functional safety and associated security levels of automotive RESS controls; (2) analyzing and assessing safety-related RESS control diagnostics, event data loggers, and prognostics; (3) identifying safety-critical information and communicating it to operators, first and second responders, and service technicians; and (4) addressing safety-related instructions and training needs.
