PFI:AIR – TT: Prototyping a Smart Battery Gauge Technology for Stationary Energy Storage of Renewable Energy Resources
Project runs from 04/01/2015 to 09/30/2019
This Accelerating Innovation Technology Translation project focuses on translating a novel Smart Battery Gauge technology to fill the increasing need for accurate battery state of charge (SOC) and remaining useful life (RUL) estimations for stationary energy storage of renewable energy. Although the large-scale integration of renewable energy into the power grid is driving for the growing demand in stationary energy storage, the reliability and safety concern remains as the major barrier that prevents its widespread deployment. The Smart Battery Gauge technology aims to improve the reliability and safety of energy storage systems. As compared to the existing battery monitoring methods, the reliably accurate estimation date generated by this technology will provide systems management and operations with the advantages of improved energy storage system efficiency, reliability, cost-effectiveness, longer lifespan, and reduced capital and operation/maintenance costs. In order to determine the technical feasibility and functional requirements of applying this technology in the stationary energy storage market and provide a commercially valuable solution, this project will result in a software prototype of the Smart Battery Gauge technology to demonstrate its real-time adaptive battery SOC and RUL estimations with market-leading accuracy and reliability, and its flexible customization for multiple different battery chemistries. The objectives of this project are to: 1) Extract the relevant data and models that are needed for RUL estimation, 2) Design the adaptive predictive battery RUL estimation algorithm that can adjust battery parameters with real-time measurement feedback, and 3) Implement and demonstrate the Smart Battery Gauge technology prototype in software and benchmark its performance with existing approaches.
