Introduction to the pressure test of energy storage bottles

Why do you need a pressure test?

Pressure tests are performed to ensure the safety, reliability, and leak tightness of pressure systems. A pressure test is required for a new pressure system before use or an existing pressure system after repair or alteration. There are two methods for pressure tests: hydrostatic and pneumatic.

Who are the authors of a protocol for measuring energy storage systems?

David R. Conover, Alasdair J. Crawford, Summer R. Ferreira, Jason Fuller, Sri Nikhil Gourisetti, David M. Rosewater, David A. Schoenwald, Vilayanur Viswanathan. Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems. Pacific Northwest National Labs and Sandia National Labs Report, 2016.

What is the test pressure for a piping system?

The test pressure for a piping system is based on the maximum design pressure of the system, and for a pressure vessel based on the maximum allowable working pressure (MAWP) of the vessel. Systems undergoing retesting should not be tested at pressures higher than the original testing pressure.

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 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.

What is a battery energy storage system?

“BATTERY ENERGY STORAGE SYSTEM (BESS)” - Stationary equipment that receives electrical energy and then utilizes batteries to store that energy to supply electrical energy at some future time. The BESS, at a minimum consists of one or more modules, a power conditioning system (PCS), battery management system (BMS) and balance of plant components.
