Zusammenfassung:	Disclosed are a drive synthesis box with multi-motors flexible torque and an electric vehicle. The drive synthesis box with multi-motors flexible torque includes at least two power sources (1) and at least two reduction gear assemblies (2). Each power source (1) includes driving motors (1A and 1B) for outputting driving force. The at least two reduction gear assemblies (2) are connected to the at least two power sources (1) in one-to-one correspondence, for transmitting the driving force. The driving motor with multiple groups of small torques and a high rotational speed is used to replace the existing driving motor with a single large torque and a low rotational speed. In this way, not only large torque requirements under a low speed working condition can be met and the power performance of the vehicle at a medium or high speed can be ensured, but also the manufacturing and procurement costs can be reduced. In addition, when a certain driving motor fails, the vehicle can still be driven normally through other driving motors, which improves the reliability of the electric driving system.
