Analysis of Traction Power of Electric Three Wheelers in Bangladesh

The traction loads supplied by the electric three-wheeler (E3W) vehicles in different drive cycles in Bangladesh are determined and analyzed here. Four real-time drive cycles have been developed; two are from a city, one from a suburban region, and one from a village area. The traction power determination process has been presented considering the features of the E3Ws and velocity profile from drive cycles, along with additional information such as passenger number and distance covered. The traction power is compared with the motor rating to show the underload and the overload operation over the drive cycles. The prospect of regenerative braking of the E3W vehicles is explored, and the sensitivity of traction power demand against tire rolling resistance coefficient is examined under the four drive cycles developed.
