Multi-speed transmission for electric vehicles (EVs) can reduce the size of the electric motor and provide an appropriate balance between efficiency and dynamic performance. Currently used multi-speed transmissions for EVs were initially designed for internal combustion engine (ICE) vehicles. Since ICEs cannot operate below certain speeds and their speed control during gear changes is not an easy task, the presence of clutches or torque convertors is inevitable for start-ups, idle running and gear changing. This, however, is not the case for EVs as electric motors are speed controllable in a wide range of operating speeds. Accordingly, transmissions without clutches or torque converters are established for EVs.
