Abstract
The effect of the application of the transmission on battery-to-wheel efficiency and fuel economy was investigated by applying an automatic transmission to a two-wheeled electric vehicle via the proving ground test at a constant velocity and the actual urban road drive. The following conclusions were drawn with this in mind. When the transmission is applied, the constant-velocity driving fuel economy and the battery-to-wheel efficiency are greatly improved. The fuel economy and efficiency are also significantly improved at low-velocity driving. In addition, if the transmission is adopted, the efficiency decreases as the velocity increases, whereas in the case of a single reducer, the efficiency increases at a high velocity. Also, the application of the transmission drastically improves the fuel economy of driving in urban areas, mainly due to the improvement of efficiency in low-velocity areas. Lastly, for further improvement of vehicle performance through the application of a transmission, an appropriate combination of motor power and transmission ratio is required.
