Description

Technical field: [0001] The invention relates to a magnetically coupled coaxial parallel structure vehicle hybrid power system and a hybrid method. Background technique: [0002] In recent years, motor vehicle exhaust emissions have become one of the important sources of urban air pollution. The maximum thermal efficiency of a gasoline engine is about 33%, and the area exceeding 30% is the restricted working area of ​​the engine. Currently, in the vehicle power system, 13% of the fuel energy is used for driving, and the remaining 87% is used as driving accessories and dissipated into the atmosphere as heat loss. At the same time, due to the increasingly congested urban traffic conditions, the car engine works at non-design points such as low efficiency and low speed for a long time, which not only increases the energy consumption of the car, but also increases the emission of harmful pollutants, resulting in the continuous deterioration of the urban air environment . Cons...
