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.
