Assessment of EV (Electric Powered Vehicle) Batteries and Application to RandD Planning.

摘要

To guide future EV battery RandD programs, the US 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 RandD plans and schedules for the most-promising developmental batteries. 6 refs., 1 fig., 6 tabs.
