This study investigated the possibility to increase electric vehicle’s energy efficiency with a two-speed gearbox. The evaluation was based on simulations on a midsize electric vehicle model. Simulations were carried out in different driving cycles and optimal gearbox parameters were determined for each driving cycle. In Case 1) efficiency maps were used for the motor and inverter. In Case 2) the inverter efficiency was assumed constant and efficiency map was used only for the electric motor. The energy saving potential in different cycles was determined. The simulation results showed that a two-speed gearbox could improve energy efficiency. The improvement depends on the driving cycle and electric drive characteristics.
