How to write a quality appraisal report for energy storage batteries

Can FEMP assess battery energy storage system performance?

This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) and others can employ to evaluate performance of deployed BESS or solar photovoltaic (PV) +BESS systems.

How to implement the recommended reporting methodology in battery research?

For a successful implementation, the suggested reporting methodology needs to be adopted by most scientists and implemented in all battery research projects for monitoring the progress beyond the state-of-the-art. Editors and Board members of high- level scientific journals could greatly assist in the implementation of such recommendations.

Why do we need a battery performance report?

The document provides the basis for the development of homogenized performance metrics and a transparent reporting methodology at cell level, necessary for the reliable benchmarking of battery chemistries.

Why is performance evaluation and comparison of battery technologies so difficult?

In this rapidly evolving field, while key performance indicators can be readily accessed, the performance evaluation and comparison of battery technologies remain a challenging task, due to the huge variation in the quality and quantity of data reported and the lack of a common methodology.

What are the KPIs of a battery system?

For battery systems, Efficiency and Demonstrated Capacity are the KPIs that can be determined from the meter data. Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out).

Are battery performance comparisons hampered by a lack of a common reporting methodology?

However, the benchmarking and performance comparison of different battery technologies are greatly hampered by the lack of a common reporting methodology.
