  • Series-parallel hybrid power system and vehicle working mode decision-making method
    Patent number: 11548368
    Abstract: A hybrid power drive system, including a power battery device, a range extender system, and a motor drive system. The power battery device is configured to supply power to the motor drive system. The range extender system includes an engine and a generator. The generator is able to generate power under the driving of the engine to supply the power to the motor drive system and/or charge the power battery device. The hybrid power drive system further includes a vehicle control unit configured to control the engine and/or generator of the range extender system to generate a driving force. The range extender system is mechanically connected to a main coupling mechanism to transmit the generated driving force to a main drive axle of a vehicle by means of the main coupling mechanism to drive wheels on both sides of the axle to rotate. Also provided is a vehicle having the hybrid power drive system.
