Gas-Based Battery Monitoring System
Technology Description:
Det Norske Veritas (DNV KEMA) is testing a new gas monitoring system developed by NexTech Materials to provide early warning signals that a battery is operating under stressful conditions and at risk of premature failure. As batteries degrade, they emit low level quantities of gas that can be measured over the course of a battery's life-time. DNV KEMA is working with NexTech to develop technology to accurately measure these gas emissions. By taking accurate stock of gas emissions within the battery pack, the monitoring method could help battery management systems predict when a battery is likely to fail. Advanced prediction models could work alongside more traditional models to optimize the performance of electrical energy storage systems going forward. In the final phase of the project, DNV KEMA will build a demonstration in a community energy storage system with Beckett Energy Systems.
Potential Impact:
If successful, DNV KEMA's gas-based battery monitoring system would ensure safe and consistent battery performance, extending their capabilities and life-times.
Security:
Advances in energy storage management could reduce the cost and increase the adoption of electric vehicles and renewable energy storage technologies, which in turn would reduce our nation's dependence on foreign sources of energy.
Environment:
Improving the reliability and safety of electric vehicles and renewable energy storage facilities would enable more widespread use of these technologies, resulting in a substantial reduction in carbon dioxide emissions.
Economy:
Enabling alternatives to conventional sources of energy could insulate consumers, businesses, and utilities from unexpected price swings.
