DNV GL has unveiled a tool that allows developers to test lithium-ion battery lifetimes and compare results across brands and applications.
DNV GL’s Battery XT independent verification tool compiles battery lifecycle data and predicts battery degradation under different conditions and duty cycles.
- The tool aims to provide low cost ways to save time and money by reducing the need for individual, customized testing protocols for each vendor.
Battery duration is growing in importance as battery deployments move up into utility scale installations. But the fact that no two markets have the same duty cycle and no two batteries have the same performance, has created bottlenecks in project deployment because every project requires a unique verification of battery life.
“As energy storage deployment reaches the gigawatt scale, the market is still challenged to overcome the self-certification approaches of the past,” Davion Hill, DNV GL’s energy storage leader, Americas, said in a statement.
As an alternative, DNV GL came up with Battery XT, which offers independent third-party testing and verification of product warrantees and performance guarantees. The tool predicts battery degradation under different conditions and duty cycles to provide independent comparisons.
DNV GL combined legacy automotive life prediction models with a minimum dataset. Once tested, the batteries can be sized to any duty cycle, and developers can scale their projects without waiting on data from suppliers.
“As the storage market continues to expand, the ability to manage risk at the point of purchase is becoming increasingly important,” Rich Barnes, executive vice president and regional manager for DNV GL Energy in North America, said in a statement.
