  4. Abstract:
  5. Battery Electric Vehicles (BEVs) are a promising solution for reducing the impacts of passenger vehicles on the environment. However, their driving range is restricted due to the limitations of battery technologies. This range can be extended by adoption of multiple-speed transmissions. Most of the comparisons in the related studies are based on non-optimal designs or limited to modal driving cycles. Furthermore, the impact of Power-Split. Continuously Variable Transmission (PS-CVT) layout with type III power How on the power consumption of BEVs has never been examined. In this paper, single-, two-, and three-speed transmissions along with PS-C'VTs with type I and III power flows are optimized for a case study of BEV. Furthermore, the effects of push bolt and full-toroidal CVTs in construction of PS-CVT are compared. The result s demonstrated that a PS-CVT with type 1 power How equipped with the full-toroidal CVT had the best performance. However, it reduced the energy consumption by 0.36% compared to the optimal two-speed layout. In addition, its ratio range was more limited, which could nogati vely impact the dynamic performance. Finally, simulation of the optimal designs along a different cycle proved that the obtained results were consistent, regardless of the driving cycle. @ 2019 Sharif University of Technology.
