The invention discloses a vehicle combined power electric transmission system and method. The system comprises an engine, a main generator, a traction converter, a power battery pack and an electric wheel combination. The engine is used for outputting mechanical energy for the main generator to drive the main generator to rotate; the main generator is used for converting the mechanical energy into first alternating current and providing the first alternating current for the traction converter; the power battery pack is used for providing second direct current for the traction converter when a preset vehicle load threshold value and a preset battery electric quantity threshold value are met and charging the vehicle when the vehicle is braked; the traction converter is used for converting the first alternating current into first direct current, and converting the first direct current and/or the second direct current into second alternating current, and providing the second alternating current for the electric wheel combination; and the electric wheel combination is used for driving the vehicle to run under the action of the second alternating current.
