During the weeks before Energy Storage Europe Düsseldorf opens, on March 12, we will showcase the top ten storage products and innovations selected by our jury. The full ranking will be published in the pv magazine energy + storage special issue 2019, created with the Messe Düsseldorf conference venue. A public award ceremony for the Energy Storage Technology Highlights will be held at Energy Storage EuropeDüsseldorf on March 13, and we are looking forward to seeing you there, from 10 am at the ESE Forum in Hall 8b.
#9 DNV GL
Keeping score of battery performance
DNV GL has released its first annual Battery Performance Scorecard to provide advice to product buyers. The testing and certification body says the tool can independently rank and evaluate battery products.
The scorecard aids the energy storage market by providing transparent, easily verifiable data with independent engineering reviews.
In its current form, the scorecard evaluates battery systems on several criteria. DNV examines whether a product’s average state of charge (SOC) is optimal for performance and the scientists then look at which SOC window shows best performance. Additional factors include battery C-rate – the rate at which a battery is discharged relative to its maximum capacity – as well as a product’s temperature behavior. Of the batteries tested, 88% were based on lithium-ion nickel manganese cobalt chemistry.
Until now, the level of battery lifetime data available to buyers was often varying and inconsistent. According to DNV GL, investors and developers have been forced to request information on battery types from the manufacturers and then had products reviewed using independent engineering reports.
That process can take months so the new independent scorecard accelerates project development.
Jury comments
Xavier Daval: “Our industry needs independent point of view frameworks to support sound development.”
Logan Goldie Scott: “The scorecard is a crucial first step in helping differentiate between battery technologies and, ultimately, providers on quality. This opaque industry needs it.”
DNV GL can be found at Energy Storage Europe in Hall 08b stand 8BC33.
