A series-parallel hybrid power system and a vehicle working mode decision-making method are provided. The series-parallel hybrid power system includes a traditional power device (1) and a motor driving device (2), the traditional power device (1) and the motor driving device (2) being able to be respectively coupled to a driving shaft (21) of a vehicle to drive wheels (22) to rotate, and the traditional power device (1) including a first engine (11); wherein the hybrid power system further includes: a power battery device (3) configured to store electric power and supply the electric power to the motor driving device (2) and/or other vehicle electrical loads; and a vehicle-mounted electric power generation device (4) including a second engine (41) and an electric power generator (42), the second engine (41) being configured to drive the electric power generator (42) to generate the electric power, such that the electric power is supplied to any of the motor driving device (2), the power battery device (3) and other vehicle electrical loads or a combination thereof. The series-parallel hybrid power system has a relatively simple mechanical structure, and can solve the problems of range anxiety, low conversion efficiency under high-speed working conditions, and complex automobile system, etc.
