Test standards for on-board energy storage power supplies

What is an electric energy storage system?

It is recognized that an 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 are ESS performance specifications & test requirements?

ESS performance specifications and test requirements vary considerably depending on the location of deployment, size, and application. Key parameters include voltage, active power, reactive power, and energy. Additionally, the test labs create application-specific tests related to performance, safety, and environmental aspects.

What are the different types of energy storage technologies?

Chemistries range from Li-Ion, NiMH, NaNiCl, NaS, ZnO, Na+, and PbSO4; and technologies range from standard to flow, metal, and super-capacitors. Practical difficulties with testing such a wide range of energy storage technologies include the wide range of applications, measurements, electrical connectivity, and digital communication protocols.

What tests should a single piece of equipment go through?

A single piece of equipment shall go through type tests, production tests, installation evaluation, and commissioning tests as a whole.
