The power assembly-hybrid structure of a new energy automobile generally has three structures: serial, parallel and series-parallel. The mechanical energy output by an engine in a series hybrid electric vehicle is firstly converted into electric energy by a generator, one part of the converted electric energy is used for charging a storage battery, and the other part of the converted electric energy drives wheels through a motor and a transmission device, so that the defects are that: after the engine is started, the high-speed running oil consumption is higher than that of a common automobile. Parallel hybrid electric vehicles use two independent drive systems of an engine and an electric motor to drive wheels, the engine and the electric motor usually drive the wheels through different clutches, and the disadvantages are that: after the electric quantity is zero, the motor cannot drive the vehicle and can only serve as a generator. The characteristics of series connection formula and parallel connection formula have been synthesized to series connection formula hybrid car structurally, have increased the transmission route of mechanical power compared with the series connection formula, have increased the transmission route of electric energy compared with the parallel connection, and its shortcoming is: the structure is complex, the efficiency is low, and the cost is correspondingly increased. In summary, the three hybrid power systems have the contradiction between irregular changes of vehicle speed and load and the rotating speed and torque area of the college engine.
