Abstract

A battery powered, rear-wheel steer loader vehicle, RWS, was developed within the Agricultural Engineering Department of South Dakota State University, Brookings, South Dakota with financial support from East River Electric Cooperative, Madison, South Dakota. The 3086 kg vehicle was propelled by a 18.65 kW de electric motor. The hydraulic system was powered by a 8. 95 kW de electric motor. The power source for the vehicle was a 72 volt battery pack. RWS had an infinite operating velocity range from 0 to 6.5 m/s. The vehicle had a draft capability of 20 kN and a maximum lift capability of 9.79 kN. RWS required an average of 5.96 kW of battery power for turning. This was 24.5 percent of the average battery power required for turning a comparably sized electric skid loader. RWS was found to operate most efficiently during light (less than 7.5 kN) drawbar pull applications. This indicated that this vehicle was best sui ted for light load applications.
