Description

 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the design of an electric vehicle electric energy system, and more particularly to a dual energy electric vehicle electric energy system incorporating wind power. BACKGROUND OF THE INVENTION With the shortage of energy, oil prices continue to rise, and other alternative energy sources are gradually being paid attention to by human beings. Foresighted researchers have already begun research and development using many other natural alternative energy sources, such as wind power plants using wind power. Power generation and power supply, Jiyang board with thermal transfer components or solar chips and solar cells use solar energy to generate electricity, which are converted into electricity by using natural energy. In the era of high oil prices, the most profound experience is the car, because the demand for and consumption of petroleum energy is large, and as the price of oil rises, the cost of operation will increase relatively. It will not only be the earth because of burning oil. Environmental pollution is a major obstacle to the global economic development. Based on two major reasons for environmental protection and high oil prices, many developers have been competing to invest in research and development solutions.

 Since the dependence of the car on fuel is still large, for this reason, there is currently a question about the dual-energy hybrid vehicle, which is the so-called hybrid electric vehicle. The hybrid vehicle includes an engine, an electric motor, and a control device that controls the power output by the engine or by the electric motor, so that the fuel and the electric energy are used interchangeably, and controlled by the engine or by the electric motor under various vehicle speed conditions. Switching to operation, and achieving fuel saving.

In addition, electric vehicles are also one of the tools that many developers are competing to develop. The basic structure of electric vehicles is to use electric power to store electric energy in the battery, control the motor action through the controller, and pass the battery power through the motor. Turning into mechanical energy, causing the tire to move relative to the ground, and the electric vehicle is relatively smooth, noise and vibration due to the explosion stroke without ICEVs. It is low, and there is no power consumption when idling, so there is no noise and vibration. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is:

 However, dual-energy hybrid vehicles still rely heavily on fuel. Once the fuel is exhausted, the hybrid vehicle must rely on the use of electricity. However, the current technology battery has limited storage capacity, which will result in dual-energy oil. Electric hybrid vehicles rely on electricity only to reduce the distance traveled. Taking an electric vehicle as an example, a battery that stores electric energy in an electric vehicle has a limited amount of stored electricity, and needs to be charged at a time to travel for a certain distance, thereby causing a problem that the vehicle has insufficient endurance, and the battery is charged for a long time, such as Gasoline vehicles can be used on roads when they are filled with oil in a short period of time. Therefore, the utility is not good and the driving distance is short.

 Therefore, improving the vehicle's endurance and shortening the charging time has become a major issue in the industry. Generally speaking, major manufacturers are moving toward increasing the battery storage capacity, but they all neglect how to use the kinetic energy of the vehicle while traveling. How to effectively utilize the kinetic energy of the vehicle as the power to charge the battery is the current pre-solved method.

 Therefore, an object of the present invention is to provide a dual energy electric vehicle electric energy system, which combines the wind energy to capture the wind energy, converts the wind part into electric power as auxiliary electric energy, and charges the battery on the electric vehicle to increase The driving distance of the electric car.

 The technical means for solving the problem of the invention:

The technical means adopted by the present invention to solve the problems of the prior art is a dual energy electric vehicle electric energy system combining wind power, including a wind power mechanism and a power supply mechanism. The power supply mechanism includes a fuel supply unit and an engine. The fuel supply unit provides a fuel to the engine to maintain the engine at a fixed speed. Furthermore, the wind power mechanism and the power supply mechanism are connected to a power access device via a clutch. The power access device has a power generation module and at least two storage batteries. Wherein, a main controller receives a wind speed signal generated by a wind speed sensing unit, and when the wind speed signal is less than a predetermined wind speed value, the control clutch is switched to be coupled to the power supply mechanism to cause the power supply mechanism to drive power generation. The module generates electricity and charges the battery. When the wind speed signal is greater than the predetermined wind speed value, the main controller controls the clutch switching to be coupled to the wind power mechanism, causing the wind power mechanism to drive the power generation module to generate electricity and charge the battery. The power access device then supplies the electrical energy to a displacement transmission to drive the displacement transmission.

 The present invention compares the efficacy of the prior art:

 The technical means adopted by the invention is that the electric energy system integrates two kinds of dual energy sources as the source of electric power required for the electric vehicle, and the technical means for converting the dual energy into electric power can effectively provide the electric power required for the electric vehicle's storage battery. The invention is to switch the electric storage and the power source as the power supply for at least two storage batteries, not only to improve the suspicion that the known electric vehicle battery needs to be charged once to complete the distance, and also prolong the battery power, so that the battery has a longer length. Use aging to extend the driving distance of electric vehicles.
