DEVELOPMENT SCHEDULES FOR VEHICLE ENERGY STORAGE SYSTEMS

The development of advanced energy storage systems for electric and hybrid electric powered vehicles is discussed. A minimum of one year for flywheels and two years for batteries will be necessary to translate most laboratory concepts into production prototype designs with a minimum of testing to establish confidence in the anticipated performance. A relatively few hand-made storage units might be installed in experimental vehicles at this stage. Regarding the goals of the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976, the panel finds that: (1) the most optimistic development time schedules preclude the inclusion of any advanced energy storage systems in Phase I of the vehicle procurements; (2) any advanced storage systems that are expected to power sizeable numbers of Phase II vehicles should pass proof-of-concept tests for performance, materials, and manufacturing methods by the fall of 1977 if moderate confidence in their availability and reliability is to be attained; (3) advanced systems that pass proof-of-concept in 1978 may be satisfactory for limited use in Phase II procurements, at least for a small number of vehicles, although confidence in their reliability will be diminished; (4) it is unlikely that any systems for which the proof-of-concept is not verified by the end of 1978 can be made available for large numbers of vehicles in the Phase II procurements with expectations of reliable operation; and (5) a relatively few of the Phase II vehicles may be powered with essentially hand-made advanced storage systems that do not have proof-of-concept verified until as late as mid-1980.
