  • In order to reduce the serious transmission loss in the online powered system for electric vehicles, a power distribution scheme based on high-voltage transfer and low-voltage stimulation was proposed. In this scheme, a high-voltage track is used to reduce the transmission loss, and a low-voltage track is utilized to enhance the ability of power transmission. The basic framework of the distribution scheme was given out, and its operating principle was expounded. In addition, the generation mechanism of the transmission loss was analyzed, the calculation formula for the transmission loss was derived, and a continuous powered approach in the tracks-switching course was investigated. Finally, simulation analysis and experiment investigation were carried out to verify the feasibility and validity of the proposed power distribution scheme and the continuous powered approach. The analysis result shows that when the transmission distance is approximately larger than 70 m, the proposed power distribution scheme can effectively improve the efficiency of remote power transmission.
