Progress in the three projects in this program during April to July 1981 is reported. For the Electric Vehicle (EV) Project, development of engineering models of electronically commutated permanent magnet propulsion motors is nearing completion, tests on a samarium-cobalt motor and a ferrite motor were completed, a Phase I ac propulsion system breadboard was installed on the Road Load Simulator, lead-acid multicell modules delivered by industrial subcontractors surpassed 390 cycles in ongoing tests and offer promise of exceeding the FY 1981 objective of 450 cycles, and ongoing tests on nickel/iron modules demonstrated greater than 670 cycles in one case, and 430 cycles in another. For the Electric Hybrid Vehicle (EHV) Project, the final report of the Environmental Control System study was received and recommends a split heat pump system, and a test program which reflects recent project modifications was planned.
