Power transfer box for experimental hybrid-electric vehicle

Abstract

© 2018 Institute of Physics Publishing. All rights reserved. This paper presents design proposal for power transfer box intended for experimental light hybrid-electric vehicle. This vehicle is originally configured as parallel hybrid with mechanical power at the rear axle and two electric hub-motors at the front axle. Vehicle should subsequently be also equipped with additional electric generator enabling charging of traction batteries for front axle drive, enabling also configuration of series hybrid or range extender. Task of the transfer box described in this paper is to connect IC engine with either rear driving axle or PTO for electric generator, or both. The goal of design process is to design the transfer box by minimizing the mass and power losses.
