Description

Battery electric vehicle windmill power generation self-powered charging device

The invention relates to the field of wind energy utilization, in particular to a wind power generation self-powered charging device for a battery electric vehicle. Background technique:

The history of human use of wind energy can be traced back to the second century AD. The ancient Persians used vertical axis windmills to mill rice. In the centuries BC, the Chinese began to use the wind to raise water for irrigation, grinding, grinding, and kites that have been passed down from ancient times. With the kite competition, it brings fun to people and the winds and turns that children like to play, wind balloons and so on.

The idea of using wind turbines to generate electricity from wind power began as early as the end of the 19th century. In 1887, American Byush built the first wind turbine for power generation, and the fastest growing country for wind power generation was Denmark. Continuous research and exploration, wind power gradually entered the industry, residential buildings, inaccessible mountainous areas, sparsely populated grassland pastures, and rural areas far from the grid, which not only facilitated life, but also saved electricity costs, and Can contribute to the protection of the environment.

In nature, wind is a kind of renewable energy, which is a great wealth given by nature in the world. However, there are some drawbacks in the use of wind energy. First, its wind speed is unstable, the energy generated is unstable, and wind energy utilization is affected by geography. The location is severely restricted, and the conversion efficiency of wind energy is also low. Although wind energy is a new type of energy, the corresponding equipment is not very mature.

How to convert wind energy into electricity more efficiently? We use it on vehicles. So far, there are countless generations of wind turbines in the world, but most of them are fixed installations. Mobile power is used in addition to ships, but rarely on land vehicles. Theory and practice tell us that a fixed installation of wind turbines, wind speed of about three meters per second, the wind turbine can start to rotate and generate electricity, as the wind is getting stronger, the output power will increase, when the wind reaches the rated wind speed The wind turbine will output its rated power.

And any long-eared living animal, the sound it emits and hears, is transmitted by oppressing the air, and the moving vehicle, in addition to oppressing the air, squeezes the air and the wind to move and drive. Fixed installation of wind turbines, we call it a wind turbine generator, when there is a certain wind speed to generate electricity, and no wind or weak wind can not generate electricity. Wind power installation On the moving vehicle, during the driving, the wind in the air pushes the wind blade, causing the wind blade to be blocked and generating lift and rotation. Based on the above principle, according to the Bezi theory, we compare the relationship between the wind level and the wind speed, air. There is wind in the wind, in the static wind state, the traffic vehicle is more than ten kilometers per hour (about 2. 8 meters per second). The wind turbine starts to rotate to drive the generator to generate electricity, while the electric two-wheeled vehicle, the tricycle, the four-wheeled vehicle Above this figure, for micro-wind power generation, it is designed to wind speed of 10-15 meters per second and 35-55 kilometers per hour, so that the rated output power of the generator is completely ok, and this is calculated by the static wind state. of,

From the principle of aerodynamics, the fixed installation of the wind turbine, the wind does not push the wind blade, but the pressure difference between the front and back of the blade is blown, such pressure difference will generate lift, make the wind wheel rotate and cross-cut Wind flow, because the wind turbine's wind wheel can't extract all the power of the wind, according to Bayes' law, the maximum power that the wind motor can extract is less than 60% of the wind power, and most wind turbines can only obtain wind power. 40% or less. See Figures 5A, 5B, and 5C, selected from Wind Energy and Wind Power Technology, Second Edition, China Beijing Chemical Industry Press, 2010. 04.

For wind turbines installed on the ground and wind turbines installed in vehicles, it has two completely different concepts. The fixed wind turbine is powered by natural wind. Its wind blades are large and long, more than 500W. The wind blades are all over 2 meters. Most of them use three blades to obtain more energy. It is unrealistic to install it on a small electric vehicle. Moreover, its balance tail is also long. When driving, it will continually oscillate, causing the vehicle to tremble and the direction is unstable, posing a threat to driving safety.

From the existing patented technical analysis, patent application No. 200610124184. 8, discloses a wind energy electric vehicle, including a power supply system, the power supply system of which is composed of a wind power generator, a charge controller, a battery pack and a power transmission controller, see 1 shows, but in this technical solution, only a single wind turbine is fixed on the top of the vehicle body through a fixed base, but this has great drawbacks, the balance tail is long, and it will continuously swing while driving, Security poses a threat, which is obviously unrealistic. The same patent application number 01107419. 1, the "Wind Energy Electric Vehicle" technical solution also has such defects.

In the invention patent application 201110131339. 1, in a solar energy and wind energy electric vehicle, a solar panel is installed on the top of the automobile, and a pipeline wind turbine is installed between the top of the automobile and the solar panel, and the vehicle is driven by wind energy and electric energy. But in practice, these two ways can’t be realized. The car travels for a long time, and it will increase the safety of the car itself.

In the three patents of the invention patent application numbers 201110237658. 0, 021 12739. 5 and 200810143128. 8 , the fan is installed outside or inside the automobile, and the fan is rotated by the wind in the driving to provide a part of the power, but Here they ignore the most important point. When the vehicle is driving, the speed of the vehicle and the direction of the vehicle will be full of variables. The corresponding wind speed and direction will also have various changes. The fan will have corresponding resistance and cannot rotate normally, especially When the fan is stressed in the lateral direction, it will generate a lot of resistance, which will cause great insecurity to the vehicle and will not achieve stable power generation.

Based on the above technical solutions, there are traffic-powered vehicles that are running, and there is no balance between the blades and the side-direction force when rotating, and this force is also the most harmful to the moving vehicle, see the figure 2. Figures 3 and 4. In summary, the self-power supply for wind turbines for vehicles is artificially squeezing and dispersing wind wind speeds in the air to achieve special windmill power generation equipment for driving purposes.

The inventor calls the wind turbine used in mobile driving as a universal wind generator, and the central controller, the automatically adjusted shock absorber and the balance flywheel play a key role, through the automatic adjustment of the shock absorption. The device and the balance flywheel cooperate with each other to adapt to these changes and achieve the purpose of smooth power generation, thereby completing the self-powered charging of the windmill generating electricity during driving.

In order to make the technical means, the authoring features, the achievement of the object and the effect of the present invention easy to understand, the present invention will be further clarified by combining the specific embodiments and the technical solutions of the present invention.

As shown in Fig. 6 and Fig. 7, the battery electric vehicle uses a windmill to generate a self-powered charging device. On the basis of the charging and power supply control circuit of the battery electric vehicle, the battery pack and the power motor, the windmill power generation system is installed. The central control system device and the windmill power generation system device convert the wind energy into electric energy, and are sent to the charging and power supply control circuit after being controlled by the central control system device, and the battery unit is connected to drive the power motor to work, thereby realizing self-power supply of the windmill. When the vehicle is in normal driving, the induced airflow and positive pressure zone and negative pressure zone will be affected by the different appearance of the car shape, so it is very important for the windmill power generation system device and the installation position.

The windmill power generation system consists of an air inlet, a wind speed sensor, a wind direction sensor, a microprocessor, a wind turbine, a wind turbine or a flywheel, a generator, an air outlet, a shock absorber and a fixed frame; the central system device is composed of a rectifier, a filter, The voltage regulator circuit, the central controller, and the charging power supply control circuit are composed. The wind turbine generates electricity through the generator, and the generated electric power is supplied to the power motor through the regulation of the central controller, and then supplied to the power motor, and the battery pack of the electric vehicle itself performs long-term battery power supply to the electric vehicle.

Here, the air inlet is different according to the shape of the car shape, and can be bell-shaped, elliptical, oblong, round, or any shape, and has a protective net cover, first considering from an aesthetic point of view, the protective net The cover should be considered as far as possible without affecting wind resistance and air intake.

The air outlets can be different on the sides of the vehicle, on the upper side or the lower side, or in the air inlets, or in parallel, on both sides, and on the upper and lower sides. In short, in consideration of aesthetics, Also consider minimizing windage and increasing airflow.

For the air inlet and outlet, it is only relative, not absolute, such as electric two-wheelers, tricycles and four-wheelers. Due to its low power, it can be used from an economic point of view and an aesthetic point of view. Like the electric fans that people use, they are equipped with a protective net, a safety cover, a generator anti-corrosion, dustproof, waterproof cover, and a fixed mounting frame. When driving, they can generate electricity as long as they reach the nominal value, and can be installed in the same car. A two or more small micro windmill power generating units to match the power matching requirements, as long as it meets traffic safety, it makes people look beautiful and comfortable.

The wind turbines are made of metal, non-ferrous metals and composite materials according to the different shapes of the car shape, different generator powers, and different installation positions. The shape of the wind blades is airfoil and variable-section blades and equal-section blades. Blades with a slurry changer, s-type blades, and straight-shaped blades may also be used. The number of wind blades may be single-leaf, two-leaf, three-leaf or multi-leaf.

When the vehicle is driving normally, it will encounter winds of different grades and directions, as well as the influence of positive wind, crosswind, return wind, vortex wind and bad weather on the wind blades, so it is necessary to regularly wind the blades. Correction and removal of deposits is necessary. From the perspective of wind and dynamics, when the vehicle is traveling in a straight line, the wind force in the upward direction of the air is the air resistance. In the air resistance, the projection of the outer shape air lift in the horizontal direction forms the differential pressure and the induced drag. According to Betz's theory and law, the differential pressure and induced resistance outside the vehicle are about 50%-90%, while the surface resistance, internal resistance and interference resistance are about 2%-30%. It can be seen that in windmill power generation, How to reduce the driving resistance is the most important, so we have studied in the air inlet and outlet, and the methods to reduce the wind resistance are mainly in the blades and outlets.

There are low-speed shafts, transmissions, clutches and high-speed shafts in the wind turbine. Depending on the appearance of the vehicle, the generator power and the size of the wind blades are different. This device may or may not be used, such as battery electric tour car, sightseeing car, due to the model. Larger, the speed is 10-20 km slower, there must be a wind turbine device to achieve the gear ratio and power supply and battery pack charging, while electric two-wheel, tricycle, four-wheeler, the speed is 30-120 km per hour, In the wind turbine, the gear transmission transmission friction causes power loss of about 8%, and noise pollution to the environment. Instead of using a wind turbine, the wind turbine and the generator are directly connected and coaxially rotated.

The generator uses special alternator, special DC generator, both of which are brushless for induction generator and permanent magnet generator. There is one of two types of generators. As you know, any kind of traffic power tool, it It is controlled by the fuel supply and chemical fuel, gas supply and air valve and power supply and controller (electric gate) to control the speed and load capacity. The same is true for special generators. According to the speed, it is controlled by the central controller. The output voltage and current are close to the set rated value. The special generator can be horizontal axis type (horizontal axis type), vertical axis type (vertical axis type), and the installation method can adopt windward or downwind type, special generator. A speed sensor that measures the speed must be installed. When the vehicle is in normal driving, due to regional differences and climate impacts, in the windmill power generation of vehicles, it is necessary to comprehensively consider the influence of altitude, air relative humidity and air density on windmill power generation, and the choice of generator material, quality, shape is Very necessary.

The wind speed sensor, the wind direction sensor and the microprocessor are installed at the air inlet. It is suitable for the wind turbine generator with the wind turbine and the gimbal. When the vehicle is running normally, the wind speed and direction sensor transmits the measured data to the microprocessor. Through the microprocessor output to the central controller, the central controller controls the windward direction of the wind turbine to control the windward direction of the wind turbine to obtain the best wind catching effect, and the speed control of the wind turbine to make the generator Stabilization is within the normal speed control. The fixing frame is mainly used for fixing and installing the shock absorber and the wind turbine generator. The mounting pattern is different depending on the mounting position of the vehicle.

Rectifier, filter, if a special alternator is used, this configuration is required to make the AC become pure DC and enter the next stage. If a DC generator is used, this configuration is not required and goes directly to the regulator circuit.

The voltage regulator circuit re-filters and regulates the DC voltage from the previous stage to reach the set value. The central controller identifies and samples the DC voltage and current from the voltage regulator circuit, and calculates the speed of the special generator, and controls the special generator in time to change its working mode and working state. When the limit value is exceeded, the central controller stops the generator from generating electricity, so that the generator becomes a mechanical no-load rotation state to protect the generator from burning out. When the speed returns to the rated value, the generator starts working again. Repeatedly, when the vehicle stops driving, the central controller, the charging power supply control circuit automatically shuts down and stops working.

Charging power supply control circuit, windmill power generation is used in battery electric vehicles. It only supports electric natural energy to increase the mileage. Therefore, before each departure, the battery pack should be fully charged by the mains, so as to achieve its high efficiency. When the battery pack is fully charged, the charging power supply control circuit can supply the battery while charging the battery pack, so that the power motor consumes less energy of the battery pack, and the charging power supply control circuit and the central controller and the battery The groups work together.

The damper can be damped spring damper, which can be used in four or six. It can also be used with a hanger type isolator and installed with three to six tension springs to achieve shock absorption and capture. the goal of. The installation of the shock absorber is mainly used for fixing the wind turbine generator assembly, which requires a free movement in a circle and can be tilted by about 10 degrees.

From the perspective of economy and safety, electric two-wheeled bicycles and electric three-wheeled bicycles are most suitable for pylon-type isolators. The installation of the damper can be balanced with a balance, so that it can be twisted and snake-shaped.

People know that any vehicle has a shock absorption system, mainly to protect the safety and comfort of life and the damage rate of equipment. Our method is to re-shock the wind power equipment while the electric vehicle has its own shock absorption. The compatibility of driving power generation.

When the vehicle is driving on the road, it will encounter uneven road surface, bumps, obstacles, uphill, downhill, evasive, turning, braking and emergency braking. The secondary shock absorption will protect the power generation equipment. Function, when the windmill is installed on a moving vehicle for rotary power generation, it will encounter changes in the vehicle at different angles and winds in different directions and winds. At this time, the shock absorber will automatically tilt and capture the wind.
