There is an injection hole inside the body, and the injection hole is The outer periphery of the hole is provided with spoiler holes. When the car is moving, it moves relative to the wind. Due to the high relative wind speed, the wind (gas) entering the air guide inlet passes through the injection holes and spoiler holes with different aperture sizes, resulting in a gas flow state that pulls each other, and then forms a gas In the case of vortex flow, the rotating device results in a gas vortex that accelerates the rotation of the windward blades, thereby driving the transmission shaft connected to the rotating device to also accelerate and rotate. When the wind is introduced from the air inlet and drives the wind rotating device to rotate, the transmission shaft (rod) also rotates synchronously to drive the generator to operate and generate electrical energy. After that, the electrical energy is transmitted to the voltage regulator through the wire, and then through The electric energy output by the voltage regulator is continuously transmitted to the power storage device (rechargeable battery, battery) through the wire, so as to achieve the purpose of continuously charging the power storage device using gas eddy current.

As shown in the first figure, it is a block diagram showing a power supply system of an electric vehicle according to an embodiment of the present invention. The power supply system 100 of the electric vehicle in this embodiment includes an eddy current power generation device 102 and a power control device 104, which can supply power to the motor 200. Eddy current power generation device 102 electrically coupled power control device Set to 104. In one example, the eddy current power generation device 102 is disposed on the front fender of an electric vehicle.

As shown in the second figure, the eddy current power generation device 102 includes an eddy current generator 110, a rotating device 112, a transmission shaft (rod) 114 and a generator 116. In one embodiment, the rotating device 112 may include a plurality of cylindrical runner with a plurality of rotating parts arranged in parallel, including a plurality of windward blades 112a, as shown in the third figure. The cylindrical runner 112 is connected to the generator 116 through the transmission shaft 114 . The cylindrical runner 112 is connected to the transmission shaft 114 . The drive shaft 114 is connected to the generator 116 . The cylindrical runner 112 is coupled to the gas vortex generator 110, and the cylindrical runner 112 includes a vertical circular surface windward blade 112a facing the wind surface. The rotating device 112 may also be a fan blade.

As an embodiment, as shown in the fourth figure, the gas vortex generator 110 has a body 111, and the body 111 is provided between the air guide inlet of the front fender of the electric vehicle and the rotating device 112. The body 111 is formed with an air inlet hole 113 and an air outlet vortex hole 115. As shown in the fifth figure, the body 111 has an injection hole 121 corresponding to the air outlet vortex hole 115 inside. The air flow introduced from the air guide inlet enters through the air inlet hole 113, forms a tapered hole shape through the injection hole 121, and then flows to the air outlet vortex hole 115 side to form a gas vortex. In addition, the body 111 is provided with a plurality of spoiler holes 123 on the outer periphery of the injection hole 121 . The injection hole 121 and the spoiler hole 123 have different hole sizes, and the hole size of the injection hole 121 is larger than the hole size of the spoiler hole 123, as shown in the sixth figure. The diameter ratio of the injection hole 121 and the spoiler hole 123 can be adjusted as needed or designed to be a fixed ratio. A vortex generating chamber 125 is provided inside the body 111 between the injection hole 121 and the air outlet vortex hole 115 . The injection hole 121 is approximately located at the center of the vortex generating chamber 125 .

In actual use of the gas vortex generator 110, the main body 111 is arranged between the air guide inlet of the front baffle of the electric vehicle and the rotating device 112, and the air inlet 113 of the main body 111 is connected to the dust filter or air filter. The filters are coupled together to prevent foreign matter from entering the internal space of the vortex generator 110 . When the gas enters the dust screen or air filter through the air inlet, and then enters the interior of the body 111 through the air inlet hole 113, the gas enters the injection hole 121 and the spoiler hole 123 respectively, and uses the injection hole 121 and the spoiler hole 123 The difference in the size of the holes causes the flow speed and amount of gas discharged after the gas enters the injection hole 121 and the spoiler hole 123 to be different. Under the same vacuum suction force, a small amount of fast gas and a large amount of slow gas are caused to pull each other, and with the space of the vortex generating chamber 125, the gas discharged from the injection hole 121 and the spoiler hole 123 forms a The phenomenon of gas rotating vortex increases the rotation speed of the rotating device 112. In one embodiment, the injection hole 121 can be formed into a tapered shape, so that when the gas enters the injection hole 121 and is discharged, the gas volume becomes smaller but is compressed to increase the flow rate. There is a pressure difference, which increases the amount of gas sucked out by the injection hole 121. The pressure increases the force of the gas vortex formed by pulling each other.

In addition, one side of the injection hole 121 corresponds to the air outlet vortex hole 115 of the body 111, and a tapered flow guide portion 127 extends from the center of the end surface, as shown in the fifth and seventh figures. The arrangement of the flow guide part 127 allows the gas flowing out of the spoiler hole 123 to be blocked by the flow guide part 127 and directed to the vortex generation chamber 125. It also prevents the spoiler hole 123 from being disturbed by the rapid airflow of the injection hole 121 as soon as the spoiler hole 123 is exhausted. , and then the gas discharged from the vortex generating chamber 125 and the air outlet vortex hole 115 are pulled together, thereby generating a vortex state with a relatively solid air outlet structure, so that the rotation speed of the rotating device 112 is greater.

Please refer to the eighth figure, the power control device 104 includes a power input terminal, a power output terminal, a power conversion unit 120, at least one battery pack 122, a boost unit 124, a charge and discharge control unit 126, an output measurement unit and Processing unit 128. The battery pack 122 includes a plurality of rechargeable batteries. In a preferred embodiment, there may be multiple battery packs 122; in this embodiment, one battery pack is taken as an example. Output terminal quantity The measuring unit is electrically connected to the power output terminal to measure an output voltage or an output current of the power output terminal.

The power input terminal is electrically connected to the generator 116 of the eddy current power generation device 102 to receive the power generated by the generator 116 . Each charge and discharge control unit 126 has an output terminal electrically connected to the power output terminal. Each rechargeable battery pack 122 is electrically connected to each charge and discharge control unit 126 on a one-to-one basis. The processing unit 128 is electrically connected to each charge and discharge control unit 126 and the output end measurement unit to control one of the charge and discharge control units 126 to cause its corresponding rechargeable battery pack 122 to output power to the power output end and receive the output end. The output voltage or output current measured by the measuring unit. When the output voltage or output current is lower than a critical value, the processing unit 128 stops the rechargeable battery pack 122 from outputting power to the power output terminal, and further controls another charge and discharge control unit 126 to cause its corresponding rechargeable battery pack 122 to output power to the power output end. end, and controls the generator 116 of the eddy current power generation device 102 to charge the rechargeable battery pack 122 that has stopped outputting power.

As shown in the eighth figure, for example, the charge and discharge control units 126 include two charge and discharge control units, and the rechargeable battery packs 122 include two rechargeable battery packs. The first rechargeable battery pack is electrically connected to the first charge and discharge control unit, and the second rechargeable battery pack is electrically connected to the second charge and discharge control unit. The processing unit 128 first controls the first charge and discharge control unit to output the power of the first rechargeable battery to the power output terminal. When the output voltage or output current is lower than the critical value, the processing unit 128 controls the first charge and discharge control unit to allow the power of the generator 116 of the eddy current power generation device 102 to charge the first rechargeable battery pack, and controls the second charge and discharge control unit. Output the power of the second rechargeable battery pack to the power output terminal. When the second rechargeable battery pack is out of power, the processing unit 128 switches back to the first rechargeable battery pack to provide power and charges the second rechargeable battery.

Through the above operation, by switching the first and second rechargeable battery packs to provide power in turn, and generating electric power for charging through the eddy current power generation device 102, the endurance of the electric vehicle is increased, allowing the user to drive the electric vehicle for a longer distance. In addition, when the charging speed is lower than the discharging speed, uninterrupted battery life will not be possible, and there will still be a time when all battery power is released. At this time, it is necessary to find an appropriate power source to charge each rechargeable battery pack. The power control device 104 includes a power conversion unit 120 and a voltage boosting unit 124. An output terminal of the power conversion unit 120 is electrically connected to the power input terminal, and the voltage boosting unit 124 is electrically connected to the power output terminal. Therefore, when both the first and second rechargeable battery packs are discharged, one input end of the power conversion unit 120 needs to be electrically connected to a commercial power source 106 to charge the first and second rechargeable battery packs. The power provided by the commercial power supply 106 is rectified and transformed through the power conversion unit 120 and then supplied to the power control device 104 for use. After the voltage boosting unit 124 boosts the power provided by the first rechargeable battery pack or the second rechargeable battery pack, the power can be provided to the motor 200 of the electric vehicle to drive the motor 200 .

For example, the mains power supply 106 provides 220V AC power. After being rectified and transformed by the electric energy conversion unit 120, it outputs 14.8V DC power to the first rechargeable battery pack and the second rechargeable battery pack. The first rechargeable battery and the second rechargeable battery output a 12V DC power to the voltage boosting unit 124, and after being boosted by the voltage boosting unit 124, a 220V DC power is generated and supplied to the motor 200 to drive the motor normally.

For example, the processing unit 128 first uses the electric power of the first rechargeable battery pack to drive the engine motor 200 to drive the vehicle through the first charge and discharge control unit. When the processing unit 128 determines that the output voltage or input current measured by the output end measurement unit is less than the critical value, it is determined that the remaining power of the first rechargeable battery pack is insufficient, and the processing unit 128 controls the first charge and discharge control unit to The electric power generated by the generator 116 of the eddy current power generation device 102 charges the first rechargeable battery pack, and controls the second charge and discharge control unit to use the third The power of the two rechargeable battery packs is output to the power output terminal.

In summary, the body 111 of the vortex generator 110 has an injection hole 121 inside, and a spoiler hole 123 is provided on the outer periphery of the injection hole. When the car is moving, it moves relative to the wind. Due to the high wind speed, the wind (gas) entering the air guide inlet passes through the injection holes and spoiler holes of different sizes, resulting in a gas flow state that pulls each other, and then forms a gas vortex. As a result, the gas vortex is generated and accelerates the rotation of the rotating device 112, thereby driving the transmission shaft connected to the rotating device 112 to also accelerate and rotate. When wind is introduced from the air guide inlet and drives the rotating device to rotate, the transmission shaft (rod) 114 also rotates synchronously to drive the generator 116 to operate and generate electrical energy. Afterwards, the electric energy of the generator 116 is transmitted to the electric energy conversion unit 120 (for example, a voltage regulator) of the power control device 104 through the wires, as shown in the eighth figure. Then, the electric energy output by the electric energy conversion unit 120 is continuously transmitted to the electric storage device (rechargeable battery, battery) 122 through wires, so as to achieve the purpose of continuously charging the electric storage device 122 by utilizing the gas eddy current.

The vortex generator 110 is connected and fixed at a suitable position of the air inlet of the electric vehicle. When the electric vehicle starts to move forward, the air inlet introduces wind force and drives the rotating device 112 to start rotating. At this time, the transmission rods 114 also rotate synchronously and drive the respective generators 116 to operate to generate electric energy. The electric energy generated by the generator 116 is transmitted to the voltage stabilizer through wires, and then the voltage stabilizer is used to stably transmit the electric energy to the rechargeable battery. According to the aforementioned operating mode, when the electric vehicle travels at a certain speed, it can continuously provide effective charging capacity to the rechargeable battery to increase the endurance of the electric vehicle.
