Zinc-Air Battery Bus Demonstration Project - Phase 3

The objective of this project is to evaluate and demonstrate the feasibility of ultra-capacitor/zinc-air battery technology for transit buses and evaluate advanced technologies for electric drive systems. The Zinc-Air Battery Bus Demonstration Program is an on-going multi-phase effort to demonstrate the proof-of-concept of zinc-air battery technology for a 40-foot transit bus. Zinc-air battery technology offers a high-energy, cost-effective energy source as a viable alternative to existing lead-acid batteries, as well as longer vehicle performance range. In Phase 3 of project, the all electric propulsion system developed in Phases 1 and 2 will continue to be enhanced and optimized, and will undergo additional testing and evaluation. A real world demonstration and peer review meeting are among the last tasks of Phase 3 of the zinc-air all electric transit bus program. Phase 1 of the program, initiated in 1998, an all-electric zinc-air battery propulsion system was integrated onto an existing 40-foot transit bus and tested. The Phase 2 effort focused on conducting evaluations of the system and vehicle performance, including track testing and limited on-road demonstrations; and upgrading the electric drive train and controls. Phase 3 activities include installation of new advanced ultra-capacitors and optimization of the electric propulsion system configuration, installation and implementation of an improved control system for various electrically operated bus auxiliaries. The bus will undergo continued performance testing on a closed track based transit bus CBD cycle. Results of the Phase 3 testing will be compared to Phase 1 and Phase 2 performance test results. The bus will also undergo a limited on-road non-revenue demonstration in conjunction with a transit agency. A Congressionally Directed Project, the results expected include: (1) further development and testing of advanced technologies for electric drive vehicles, including an ultra-capacitor that provides an energy storage system that is compact, lightweight, and critical for improved hybrid bus performance. This program is past of the Federal Transit Agency's (FTA's) Electric and Hybrid electric vehicle effort to foster development and deployment of electric drive propulsion systems that can be used in a wide range of transit applications to improve air quality, reduce greenhouse gas emissions, and reduce the transportation sector's consumption of petroleum.
