DNV GL has created Battery XT, a testing-based verification of battery lifetime for Li-on batteries. The independent verification tool compiles battery life cycle data and predicts battery degradation under different conditions and duty cycles, providing renewables stakeholders with an objective way to compare the value and reliability of types and brands of energy storage technology. Battery XT offers an independent third-party testing and verification of product warrantees and performance guarantees before making a purchasing decision. Battery XT, which can also provide consulting on battery size and chemistry selection, aims to reduce risk and inform purchases and planning for energy storage asset management. The independent verification enables the industry to test at a low cost, helping stakeholders save time and money by eliminating the need to address individual, customized testing protocols for each vendor. DNV GL offers an interactive online demo to illustrate the way Battery XT works. Viewers can try three scenarios-fast charge electric ferry, hybrid genset, and solar+frequency by entering sample information such as system size, temperature, and initial state of change, and then running a simulator to show how the factors apply. The full service offered on a per project basis is able to tailor even the most complex duty cycle to the customer and their battery.
