Assessment of EV Batteries and Application to R&D Planning

To guide future EV battery R&D programs, the U.S. Department of Energy (DOE) commissioned a comprehensive assessment of secondary battery technologies. A total of 67 battery developers-from the United States, Canada, Europe, Asia, and Africa-were solicited to submit battery design concepts for an “Improved Dual-Shaft Electric Propulsion” (IDSEP) van. A team of 10 consultants and 7 representatives from DOE laboratories evaluated 42 developer responses and consultant-prepared designs. Using six criteria-five technical/economic criteria and a maturity/technical barriers criterion-the assessment identified 12 most-promising batteries. Employing a generic EV-battery development-system framework, the assessment results are being used to formulate multi-year R&D plans and schedules for the most-promising developmental batteries.
