Abstract
In this study, the effect of increases in user weight and road slope on energy consumption (Wh/km) value of a disabled vehicle driven with permanent magnet synchronous motor (PMSM) was investigated. In order to digitize this effect, a test system consisting of a data reading card and an interface program prepared in Visual C # was developed. In this way, information about the disabled vehicle and the road was collected instantly during the test process and visualized in the interface. Then experimental studies were carried out on two roads with different slopes with users of different weights. Finally, by using the obtained results, the effect of increases in road slope and user weight on the energy consumption of the vehicle was demonstrated by numerical data. By using these results, the numerical simulations of battery-operated disabled vehicles can be calibrated and much more realistic simulation results can be obtained in future studies.
Highlights
ENERGY CONSUMPTION (Wh/km) values of disabled vehicles are very important issues for people who use these vehicles
The average values of instantaneous power drawn from the battery at user weights of 35 kg, 50 kg, 70 kg and 95 kg are 75.72 W, 81.34 W, 86.21 W and 92.53 W, respectively
The effects of both road slope and user weight on the vehicle's energy consumption value in the disabled vehicle driven with permanent magnet synchronous motor (PMSM) were examined together
Summary
The powers of the motors to be mounted on electric vehicles are determined by taking into account the climbing angle of the vehicle and some forces affecting the vehicle. As a result of the calculations, it has been found that the motor to be mounted to the disabled vehicle should produce 16.25 Nm, 10 Nm and 3.75 Nm of torque on + 20°, 0° and -20° roads, respectively. The effect of road slope and user weight on energy consumption in a disabled vehicle driven with permanent magnet synchronous motor (PMSM) was obtained. The effect of the increases in road slope and user weight on energy consumption has been revealed with numerical data
