Functional safety design of energy storage system

What is functional safety?

system or equipment operating correctly in response to inputs. Functional safety is achieved when all the specified safety functions are carried out and the level of performance required of each safety function has been met. Functional safety is undertaken by active systems. Safety achieved by passive elements is not considered functional safety.

What is the goal of generating 'Functional Safety Requirements'?

The goal in generating 'Functional Safety Requirements' is to establish methods that can ensure that the parameters monitored by the system components are validated1 and correct2, and that the actions taken by the system components are correct and confirmed.

What are functional safety requirements (FSCs)?

Functional Safety Requirements (FSCs) are derived from safety goals in conjunction with Functional Safety Concepts (FSCs). They are allocated to the preliminary architectural elements of the system or to external risk reduction measures to achieve a specific level of safety.

Is functional safety a risk?

Functional safety is undertaken by active systems. Safety achieved by passive elements is not considered functional safety. A risk is the chance, high or low, that somebody could be harmed by a hazard, plus an indication of how serious the harm could be.

What is the Energy Storage Safety Strategic Plan?

The Energy Storage Safety Strategic Plan was developed by Pacific Northwest Laboratory and Sandia National Laboratories with the support of the Department of Energy’s Office of Electricity Delivery and Energy Reliability Energy Storage Program since July 2015.

What do functional safety concepts provide information on?

Functional safety concepts provide information on conditions and causes that could lead to the violation of a safety goal or safety requirement. They also support the identification of additional requirements for verifying that the functional safety concept complies with safety goals and safety requirements, including safety-related vehicle testing.
