Energy storage cell test

What are some useful reports about energy storage testing?

Below is a non-exhaustive list of valuable reports that the working group has relied on when becoming familiar with storage testing. “Electric energy storage – future storage demand” by International Energy Agency (IEA) Annex ECES 26, 2015, C. Doetsch, B. Droste-Franke, G. Mulder, Y. Scholz, M. Perrin.

Where can I find performance and testing protocols for stationary energy storage systems?

The United States has several sources for performance and testing protocols on stationary energy storage systems. This research focuses on the protocols established by National Labs (Sandia National Laboratories and PNNL being two key labs in this area) and the Institute of Electrical and Electronics Engineers (IEEE).

What are energy storage systems?

Energy storage systems (ESSs), and particularly battery energy storage systems, are finding their way into a very wide range of applications for utilities, commercial, industrial, military and residential power. Applications include renewable integration, frequency regulation, critical backup power, peak shaving, load leveling, and more.

Should a system be tested on a cell or a module?

When conducting tests, the tests can be done on cells, modules, or the entire system. The benefit of testing on cells is that it is easier, cheaper, and safer. The downside to this is that it does not represent the entire system, and a system is judged on its worst cell.

Do energy storage test protocols work in different regions?

One of the Energy Storage Partnership partners in this working group, the National Renewable Energy Laboratory, has moved forward to collect and analyze information about the existing energy storage test protocols and their use in different regions around the world. This chapter summarizes that information for several key regions globally.

How do you test a cell for thermal runaway?

Thermal runaway methodology for unit level test: The propensity of the cell to exhibit thermal runaway be demonstrated by heating the cell with externally applied heaters. With a surface heating rate of 4oC (7.2oF) to 7oC (12.6oF) per minute until cell thermal runaway occurs within the test unit.
