This paper presents the results of performance characterization testing of the extended-range Conceptor G Van electric vehicle (EV). Testing was performed at the Electrotek Electric Vehicle Test Facility (EVTF) as part of the Electric Power Research Institute (EPRI)/Electrotek EV Program. This extended-range EV (XREV) is based on the electric G Van, which is a GMC full-sized van converted to electric propulsion by Conceptor Industries of Newmarket (Toronto), Ontario. A 7-kW Onan gasoline engine/generator (E/G) set was retrofitted into the vehicle by McKee Engineering of Lake Zurich, Illinois. The XREV utilizes tubular-plate lead-acid batteries and dc powertrain components furnished by Chloride EV Systems of Redditch, England. Testing was conducted according to the EPRI/Electrotek EV Test Plan and included measurement of driving range on the SAE J227a C Cycle, on the Electrotek-defined Chattanooga City Cycle (CCC), and at four constant speeds from 56 km/h to 80 km/h.

This paper presents the results of performance characterization testing of two prototype Vehma G Van electric vehicles (EVs). Testing was performed at the Electrotek Electric Vehicle Test Facility (EVTF) as part of the Electric Power Research Institute (EPRI)/Electrotek EV Program. The G Van is a GMC full-sized van converted to electric propulsion by Vehma International of Toronto, Ontario. One of the vans tested at the EVTF was a five-passenger model, the other was a two-seat cargo van. These vehicles utilize tubular-plate lead-acid batteries and dc powertrain system components produced by Chloride EV Systems of Redditch, England. Performance testing was conducted according to the EPRI/Electrotek EV Test Plan and included measurement of driving range at 56 km/h, on the SAE J227a C cycle, and on the Electrotek-defined Urban route. Vehicle top speed, maximum acceleration, dc and ac energy consumption, hill climbing, and braking capabilities also were measured.
