Energy storage module welding inspection standard

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

What is an energy storage system (ESS)?

Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.

What are ESS safety standards?

Considering ESS safety from a ground-up perspective, standards will apply to the smallest parts of the system (e.g., wires, relays, switches, etc.) to address their design, construction, and safety features to serve their intended purpose.

Do electric energy storage systems need to be tested?

It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.

What should be included in a weld inspection area?

The inspection area shall include the weld and the accessible adjacent base material for a distance of 1.2 inch from the toes of the weld of edge of the base metal, whichever is less. Material thickness shall be the nominal or actual thickness as specified on the engineering drawing or material specification.

What are ESS requirements?

These requirements cover ESS that are intended to store energy from power or other sources and provide electrical or other types of energy to loads or power conversion equipment.
