What is the performance and functional testing of energy storage systems?

This manual addresses the performance and functional testing of energy storage systems (ESSs). The objective is to provide specific, detailed test procedures that are reproducible so that utilities and other testing entities can easily use them for the performance evaluation of energy storage systems . The key principles that guide this effort:

What is battery capacity testing?

Capacity testing is performed to understand how much charge / energy a battery can store and how efficient it is. In energy storage applications, it is often just as important how much energy a battery can absorb, hence we measure both charge and discharge capacities.

How do integrated system tests measure energy storage performance?

Integrated system tests are applied uniformly across energy storage technologies to yield performance data. Duty-cycle testing can produce data on application-specific performance of energy storage systems. This chapter reviewed a range of duty-cycle tests intended to measure performance of energy storage supplying grid services.

What is the basic testing and characterization of energy storage systems?

The Basic Testing and Characterization of Energy Storage Systems is intended to be storage- technology agnostic, encompassing all electricity -in, electricity -out energy storage technologies.

These test procedures include available energy capacity; charge duration; rated continuous power; auxiliary load determination; roundtrip efficiency; response, rise, and settling time; harmonic distortion; self-discharge rate; startup and shutdown time; charge/discharge management; volt-VAR regulation; autonomous frequency regulation; peak power limiting; and operational performance tests.
