Description
technical field:
the method provided is provided for the cascaded structure hybrid power system for automobile and the two kinds of power that the present invention relates to a kind of magnetic couple.
background technology:
in recent years, motor vehicle exhaust gases discharges oneself becomes one of important sources of urban atmospheric pollution.Petrolic high thermal efficiency is 33% left and right, and surpassing 30% zone is exactly the restricted work area of driving engine.Current, in automobile dynamic system, fuel energy 13% for travelling, remaining 87% is used as driving accessory and becoming waste of heat and is diffused in atmosphere.Simultaneously, due to the urban traffic conditions day by day blocked up, cause the automotive engine lower off-design points such as slow speed of revolution in efficiency that work long hours, not only aggravated the automobile energy consumption, and the discharge of noxious pollutant constantly increases, cause the urban air environment constantly severe.Consider a large amount of consumption, orthodox car exhaust emissions of the non-renewable resources such as the oil pollution to environment, the cry of environmental protection and energy saving grows to even greater heights, and research environmental protection, energy-efficient automobile dynamic system are very urgent.
hybrid power system is to have more than one transformation of energy modes that the system that drives power is provided.Hybrid power system adopts suitable fuel transfer device (as combustion engine), closed-center system and electrical motor as hybrid power source, under tight control policy is controlled, make fuel transfer device, closed-center system and motor be operated in as far as possible high efficiency, low emission zone under the driving operating mode.Thereby greatly improve fuel-economy performance, exhaust emissions performance and other in-use performance of automobile when different operating modes are travelled.Hybrid vehicle combines the advantage of traditional combustion engine automobile and electronlmobil, and course continuation mileage is unrestricted, and little for the change of orthodox car, and the input that industrialization is produced is compared also much less of fuel cell powered vehicle.
at present, the power system of hybrid vehicle mainly is divided into series, parallel and three kinds of forms of series-parallel connection.
its advantage of cascade system is that the operation of driving engine is independent of the speed of a motor vehicle and road conditions, engine behavior is not subject to the impact of automobile running working condition, can remain under stable, efficient, oligosaprobic state and turn round, driving engine has good economy and low discharge index.Shortcoming is in the conversion process of energy of heat energy-electric energy in the cascade system of Engine-Generator-driving motor-mechanical energy, the energy transmission loss is larger, also have waste of power in the charge and discharge process of power battery pack, the total combined efficiency of transformation of energy is lower than internal-combustion engines vehicle.
in parallel system, driving engine and electrical motor can provide power to automobile driving wheel respectively independently, there is no the electrical generator in tandem HEV Power Train, the mechanical energy of driving engine can directly output to automobile drive axle, centre does not have the conversion of energy, arrange and compare with tandem, system effectiveness is higher, and fuel oil consumption is also less.But, due to direct mechanical connection being arranged between driving engine and driving wheel of vehicle, engine operation condition inevitably will be subject to the impact of the concrete driving cycle of automobile.
combined hybrid system is tandem and parallel comprehensive, it has given full play to tandem and parallel advantage, can make the parts such as driving engine, electrical generator, electrical motor carry out more Optimized Matching, thereby structurally guarantee still can make system to work under optimum state under more complicated operating mode.But its structure is very complicated, its match control is also very difficult simultaneously.
in sum, hybrid power system can not well meet the demand of advanced environment-friendly energy-saving automobile at present, hybrid power system technology in the urgent need to development of new, effectively overcome the problem that efficiency low, exhaust emission high of driving engine when low speed and off-design point, realize green high-efficient and the energy-conserving and environment-protective of automobile.
