The US Advanced Battery Consortium (USABC) has awarded $2.68 million to San Diego-basedÂ Maxwell Technologies for the development of a hybrid energy storage system for automotive stop-start applications. The competitively bid contract award is co-funded by the DOE.
The 19-month program will focus on the technological and economic feasibility of adapting a 12-volt hybrid energy storage system consisting of lithium-ion batteries and Maxwell ultracapacitors to an automotive stop-start application, including the development of an improved capacitor.
â€œWe are pleased to announce the award of this contract to Maxwell Technologies as part of USABCâ€™s broad battery technology research and development programs,â€ said Steve Zimmer, Executive Director of USCAR. â€œThese programs are essential to advance the technology needed to meet both near- and long-term goals that will enable increasingly efficient and affordable vehicle electrification.â€
Separately, USABC has issued a request for proposal for the development of high-performance electrolytes for lithium-ion vehicle batteries. The proposed technology is expected to provide a significant improvement over existing electrolytes in one or more of the following areas:
- Selling price
- Low-temperature (-30Â° C) conductivity
- High-voltage stability
- Vapor pressure at 30Â° C
- Component purity
