Dynamometer testing of the U.S. Electricar Geo Prizm conversion electric vehicle

PDF Version Also Available for Download.

Description

A Geo Prizm electric vehicle conversion by U.S. Electricar was tested in the INEL HEV Laboratory over several standard driving regimes. The vehicle, owned by the Los Angeles Department of Water and Power (LADWP), was loaned to the INEL for performance testing under a Cooperative Research and Development Agreement (CRADA) between the U.S. Department of Energy (DOE) and the California Air Resources Board (CARB). The Prizm conversion is the fourth vehicle in the planned test series. A summary of the test results is presented as Table ES-1. For the LA-92 and the Highway Fuel Economy Test cycles, the driving cycle ... continued below

Description

A Geo Prizm electric vehicle conversion by U.S. Electricar was tested in the INEL HEV Laboratory over several standard driving regimes. The vehicle, owned by the Los Angeles Department of Water and Power (LADWP), was loaned to the INEL for performance testing under a Cooperative Research and Development Agreement (CRADA) between the U.S. Department of Energy (DOE) and the California Air Resources Board (CARB). The Prizm conversion is the fourth vehicle in the planned test series. A summary of the test results is presented as Table ES-1. For the LA-92 and the Highway Fuel Economy Test cycles, the driving cycle ranges were 71 and 95 km, respectively. The net DC energy consumption during these cycles was measured at 199 and 154 W-h/km, respectively. During the constant-current-discharge test, the vehicle was driven 150 km at an average steady speed of 43 km/h. Energy consumption at various steady-state speeds, averaged over two tests, was approximately 108 W-h/km at 40 km/hr and 175 W-h/km at 96 km/h at 80T state-of-charge (SOC). Gradeability-at-speed tests indicated that the vehicle can be driven at 80 km/h up a simulated 5% grade for periods up to 15 minutes beginning at an initial 100% SOC, and 3 minutes beginning at 80% battery depth-of-discharge (DOD). Maximum-effort vehicle acceleration times were determined at five different battery DODs and speeds from 24 to 104 km/h. The acceleration is approximately linear up to 48 km/h, with no DOD effect; at higher speeds the curve becomes non-linear, and the effect of DOD becomes increasingly evident. Gradeability at each of these speeds was also determined, showing a decrease from the initial 26% at 24 km/h to 4% at 104 km/h.
