Critical Need: 
Today's electric vehicle batteries are expensive and prone to unexpected failure. Batteries are complex systems, and developing techniques to cost-effectively monitor and manage important performance measures while predicting battery cell degradation and failure remains a key technological challenge. There is a critical need for breakthrough technologies that can be practically deployed for superior management of both electric vehicle batteries and renewable energy storage systems.
Project Innovation + Advantages: 
Gayle is developing a laser-guided, ultrasonic electric vehicle battery inspection system that would help gather precise diagnostic data on battery performance. The batteries used in hybrid vehicles are highly complex, requiring advanced management systems to maximize their performance. Gayle's laser-guided, ultrasonic system would allow for diagnosis of various aspects of the battery system, including inspection for defects during manufacturing and assembly, battery state-of-health, and flaws that develop from mechanical or chemical issues with the battery system during use. Because of its non-invasive nature, relatively low cost, and potential for yielding broad information content, this innovative technology could increase productivity in battery manufacturing and better monitor battery conditions during use or service.
Impact Summary: 
If successful, Gayle's laser-guided, ultrasonic battery diagnosis system would facilitate a significant improvement in vehicle battery safety, reliability, and performance.
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.
