Technology Advantage and Differentiation Novel, non invasive sensing technique for battery degradation and off gas Validation and economic test of second life of batteries Deployment of second life system with sensors in a commercial community energy storage system Sensor Enhanced and Model Validated Life Extension of Batteries for Energy Storage DNV, NexTech Materials, Beckett Energy Systems Davion Hill, Ph.D., Senior Engineer DNV Research , Performance Targets Please contact regarding: R&D, technology validation, collaboration, press, business development MetricState of the ArtProposed Sensor for multiple cell faults Temperature or voltage Novel off-gas sensor Battery life prediction with +/- 10% accuracy Intentional overdesign Life extension with doubled revenue Demonstration of second life in CES Never been done Validation of performance The sensor concept is unobtrusive and nondestructive. Monitoring in this fashion offers the following benefits: Improved safety Providing a warning mechanism for flammable off gas Correlating state of health or stress with off gas activity Viable for stationary or mobile applications Addressing safety is a unique feature of this technology. DNV is testing a novel off gas measurement concept to detect degradation in Li-ion batteries. This monitoring and measurement concept will be used to monitor batteries under varied stress, and demonstrate safe monitoring of second life batteries in a community energy storage application.
