Description

Power generation structure for electric automobile and kinetic energy circulating conversion control method
Technical Field
The invention relates to the technical field of electric automobile structures and kinetic energy cycle conversion control, in particular to a power generation structure and a kinetic energy cycle conversion control method for an electric automobile.
Background
In the prior art, the highest practical utilization rate of energy in the running process of an automobile is only about 60%, and the reasons for generating energy loss mainly comprise the following aspects: 1. all vehicles running on the road must be highly equipped with power equipment, which is a special requirement for vehicle power output such as vehicle load, road condition, and instantaneous acceleration performance under special conditions possibly encountered during vehicle running, in order to overcome the rotational inertia of each transmission system during vehicle load and smooth starting when the vehicles are fully loaded and uphill, all vehicles must be matched with power equipment with power much larger than that required by the vehicles for stable running, but the power of the power equipment matched when the vehicles finish starting and enter stable running is far larger than the required power, under the condition, the reactive loss of the vehicle power equipment is inevitably increased, the reactive waste of energy during vehicle running is caused, if the power equipment is not matched with the power equipment larger than that of the vehicles for normal running, the running of climbing and starting under complex road conditions cannot be normally realized, and meanwhile, when the power equipment and the vehicles do not form a certain rotational potential energy, the starting and low-speed running of the vehicle are energy-consuming, the time of needing larger power is generally shorter when the vehicle starts or climbs a slope under the common condition, and the normal stable running time is very long, so that the energy consumption is inevitably wasted by equipping the super-power equipment for the purpose of starting or climbing the slope in very short time; 2. the energy loss caused by friction heat generation of the power equipment, the transmission system and the brake system is that most of the energy of the whole vehicle, including the fuel energy used by the internal combustion engine and the electric energy used by the electric motor, is lost due to the friction heat generation in the process of converting mechanical energy, and particularly the energy loss of the internal combustion engine is particularly large, and comprises the energy loss caused by heat dissipation of a cooling system and heat removal of an exhaust system and the friction heat generation in braking, the energy loss caused by incomplete fuel combustion and the energy loss caused by the friction heat generation of each rotating part in the speed changing and transmission mechanism. 3. Various resistances during the running of the vehicle have certain influence on energy loss; the energy loss caused by the out-of-roundness of tires is different from the energy loss caused by windage resistance due to different vehicle body streamline shapes, the resistance of a vehicle in running is relatively small due to good vehicle body streamline shapes, the energy loss is relatively small, the running resistance of the vehicle with poor vehicle body streamline shapes is relatively large, the energy loss is generated due to the fact that wheels slip and generate heat when the wheels encounter ice and snow or wet and slippery road surfaces, the energy loss is increased due to the fact that the tires are out of round due to insufficient inflation, the rotation resistance is increased, the energy loss causes the energy efficiency utilization rate of the vehicle to be about 40% generally, the highest energy efficiency utilization rate is less than 60%, and the effective utilization rate of the energy is very low.
The effective utilization rate of energy is closely related to the whole vehicle technology, the advantages and disadvantages of the whole vehicle comprehensive technology are key links influencing the energy efficiency, the effective utilization rates of the energy are different among different brands, different manufacturers and different mechanical technologies, at present, part of domestic brands of vehicle types apply the energy recovery technology on electric vehicles or oil-electricity hybrid vehicles, and certain effects of saving energy, reducing consumption and increasing endurance mileage are obtained, the brands of vehicle types mainly adopt motors to switch generators to generate electricity to recover the energy, some are called regenerative braking, and some are called energy feedback, the technology has the advantages of simple structure, the kinetic energy can be converted into the electric energy to be used for charging storage batteries and using electric equipment when the vehicle is decelerated or braked, the consumption of the electric quantity of the storage batteries is reduced to a certain extent, the endurance mileage is increased, but the technology has certain weakness, firstly, the kinetic energy recovery has discontinuity, the motor is switched into a power generation mode to start to recover the kinetic energy only when the vehicle needs to decelerate, the kinetic energy can not be recovered when the vehicle normally runs and is stable, and the kinetic energy is recovered when the vehicle speed is reduced, so that the kinetic energy is rapidly reduced along with the reduction of the vehicle speed, and the effect generated by the transient kinetic energy recovery is not great; secondly, the system fusion degree is not enough in the process of converting the motor to the generator, so that the magnetic resistance force generated instantaneously by the excitation of the generator generates dragging feeling for the normally running vehicle, and the riding comfort is reduced; thirdly, the vehicle is decelerated or stopped through resistance generated in power generation so as to enable the kinetic energy recovery to be incomplete and cause most of kinetic energy to be wasted, the vehicle is enabled to be always repeatedly stopped and stopped in the running process according to the traffic condition when people and vehicles in urban areas are mixed according to the complex road condition in the normal running process of the vehicle, the vehicle can be stopped and stopped at low speed and high speed sometimes, and emergency braking can be carried out in case of emergency, the complex working conditions in the running process are all completed by controlling an accelerator pedal and a brake pedal by a driver, when the driver steps on the brake pedal according to the deceleration or stop requirement in the running process, the resistance of an energy absorption system is lower than the resistance required in the braking process, or the absorbed energy exceeds the battery charging or the electricity utilization rate of electric equipment, the kinetic energy is still converted into useless heat energy to be dissipated into the environment in a friction heat generation mode through the traditional brake, so that the kinetic energy recovery has the defects of incomplete conversion and low utilization rate through the simple kinetic energy recovery mode (ii) a Under the prior art, we have found that the electric vehicle has the defects in energy saving and energy recovery, but at the same time we know the difficulties faced in utilizing the kinetic energy recovery and conversion utilization, which are mainly reflected in the characteristics of the kinetic energy and the structure and technical means of the vehicle, wherein the difficulties faced are mainly reflected in that: the kinetic energy characteristics of a vehicle in running are generally represented by instability and dispersion of energy magnitude and intensity, the dispersion of the kinetic energy of the vehicle in running is mainly represented by that any part of the whole vehicle body can generate mechanical reaction no matter being touched with anything, the kinetic energy in running of the vehicle is composed of the weight and the speed of the vehicle body, the speed is the same, the kinetic energy formed by the mass of the vehicle body is larger, the speed is the same, the kinetic energy is larger, the kinetic energy is composed of the weight and the running speed, therefore, the kinetic energy is distributed over the whole vehicle body, and the technical difficulty in conversion and utilization of the kinetic energy is also included: 1. kinetic energy formed during the running of the vehicle has the characteristic of being not storable; 2. kinetic energy is hysteresis force which cannot be directly used as driving force, acting force acting on a vehicle body is always weakened from strong force due to various factors such as complex working conditions of roads and traffic, air resistance in driving and the like, and the force reflected by the kinetic energy is hysteresis force which cannot be directly used as the driving force; 3. the problem of energy conservation is faced when a generator is arranged on a vehicle for power generation, and how to overcome the magnetic resistance generated during power generation load; 4. in the vehicle structure and the power generation transmission technology, a series of technical problems that the dispersed kinetic energy is led out from the vehicle body, the amount of the led-out kinetic energy is large, the transmission mode is adopted to take out the kinetic energy, the power requirement of the whole vehicle is fused with the power of the generator, the power generated by the generator is fused with a storage battery and power utilization equipment and the like need to be overcome.
The electric energy is the only energy of the electric automobile, the pure electric automobile completely depends on the charge-discharge cycle power supply of the storage battery at present, the electric quantity and the voltage of the storage battery are continuously reduced along with the increase of the driving mileage due to the limited electric storage space of the storage battery, sometimes, a certain electric quantity is displayed by an instrument, but the electric automobile cannot be driven due to sudden power failure during driving, the electric automobile industry in China is fast in development speed and widely witnessed in the world of scale, governments and electric automobile enterprises also try to solve the difficult problems of the use of the electric automobile by consumers in imagination, wherein the most core difficult problem is to solve the problems of the driving mileage and the charging of the electric automobile, the research and development of enterprises are also enhanced on the driving mileage of the storage battery, the matching of charging facilities in a small area, the construction of charging and replacing services and other measures are enhanced to improve the defects of the use of the electric automobile, however, the construction of the national guide quick charging station needs a large amount of funds and fields, and relates to the income and risk problems of investment subjects, because the technology of the electric vehicle comprises a plurality of uncertain factors of the storage battery technology, and the factors can directly influence the future development prospect of the electric vehicle, a series of uncertainties can lead investors not to dare to invest easily, and secondly, enterprises can develop the construction of charging supporting facilities in districts and the construction of power changing stations are also difficult to face, firstly, different types of batteries have different requirements on the charging facilities, if the technical parameters of the charging pile and the batteries are not matched to charge the batteries, certain influence can be caused on the service life of the batteries, especially, the types of the batteries used by various automobile manufacturers are different at present, and the national charging pile has no unified standard for the types of the electric batteries and the matching problem with the charging pile for the automobiles, the quality and the charging technology of the battery are not perfect, so that the problems of too short driving mileage, too long charging waiting time, short service life of the battery, too high cost and the like are caused, and secondly, enterprises need to comply with the consent of community pipes or neighbors of electric automobile users when building charging facilities in communities; thirdly, enterprises build the power station and face a lot of difficult problems, firstly, the storage batteries used by the electric vehicles at present are various, the quality, the new and old differences and the like cause the power station to be very headache, and because the electric vehicles are influenced by the storage battery storage capacity, the storage battery temperature, the charging station network and the charging supporting facilities, users always worry about worry psychology caused by the fact that the storage battery voltage is reduced or the electric quantity is used up and the vehicles cannot run, and the rapid development of the electric vehicle industry can be directly influenced by a plurality of adverse factors.
