Provided are an electric drive system for a motor vehicle and a motor vehicle using the electric drive system. The electric drive system for a motor vehicle comprises: an inverter unit () configured to convert externally-supplied DC power to AC power; an electric motor unit () configured to convert the power from the inverter unit () into mechanical rotation and output the mechanical rotation from an output shaft (); and a gearbox unit () configured to decelerate the rotation transmitted from an input shaft () and output the decelerated rotation. The electric motor unit (), the gearbox unit () and the inverter unit () have respective independent enclosures. The electric motor unit (), the gearbox unit () and the inverter unit () are detachably and mutually connected in an axial direction along the input shaft () of the gearbox unit () with the gearbox unit () positioned in between. The enclosure of the inverter unit () has the minimum thickness in the axial direction.

A dual-motor power system or a dual-motor hybrid power system for a vehicle comprises a first motor, a second motor, an intermediate shaft, a first gear set disposed between a first driving shaft, and an intermediate shaft. The first driving shaft couples with the intermediate shaft via the first gear set, a second gear set disposed between the second driving shaft and the intermediate shaft, and a single synchronizer disposed around the second driving shaft. The synchronizer can be switched between a neutral position, a first-speed-ratio position, and a second-speed-ratio position. In the neutral position, the second driving shaft is decoupled from the first and second gear sets. In the first-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the first gear set. In the second-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the second gear set.
