The invention discloses a vehicle-mounted charging and driving motor integrated system of an electric vehicle and a working method of the vehicle-mounted charging and driving motor integrated system, and belongs to the technical field of electric vehicle charging. The problems that in the prior art, an electric vehicle charging device and a driving device are combined little in structure and function, the working mode is single, and the power density is low are solved. The system comprises a switch unit, an input unit, a motor unit, an energy conversion unit and a battery unit. The working method comprises a charging mode, a driving mode, an electric energy feedback mode, a braking energy feedback mode and a fault-tolerant mode. The power density of the integrated system is effectively improved, and different requirements of the electric automobile are met.
