Assurance and risk management specialist DNV has released the fourth edition of its Battery Scorecard report, which is available for free download.

DNV’s Battery Scorecard is designed to provide answers to pressing questions about battery safety, useful life and degradation, for both EVs and stationary storage applications. This edition incorporates independent testing results for 19 different battery cell types, as well as an assessment of future battery technologies.

DNV tested cell performance in three different applications: less than 2-hour grid support; 4-hour solar shifting; and a high-power vehicle application. It also tested calendar fade, BMS optimization and safety.

“Engineers, developers, and owners need a solid understanding of their battery systems,” says DNV. “Selecting suitable technology suppliers is one of the most important and challenging endeavors for project developers. While batteries have been commercially available for decades, most stationary storage products are less than five years old. The Battery Scorecard provides project developers and owners data and insights that can help them select the correct technologies for the unique conditions of their projects.”  

“As energy storage further penetrates energy markets and infrastructure, proven safety and overall performance will become essential to projects,” said Richard S. Barnes, Region President, Energy Systems North America at DNV. “The best and most accurate way to ensure performance and safety is through testing.”
