Description

A power generation and energy storage system that does not require a voltage stabilizing and current limiting circuit board for generators with power below 1KW Technical Field

[0001] The present invention relates to a power generation and energy storage system, and more particularly to a power generation and energy storage system in which a generator does not use a voltage stabilizing and current limiting circuit and can output a voltage higher than a battery voltage and a generator power below 1Kw without using a voltage stabilizing and current limiting circuit board. Background Art

[0002] With the dwindling availability of fossil fuels and rising environmental awareness, countries around the world have been actively developing green energy, hoping to reduce their dependence on raw materials like oil and coal. Currently, solar power generation is a relatively mature and environmentally friendly method. However, solar power generation below 1kW is not only affected by seasonal fluctuations, but also by factors such as cloudy and rainy days, daytime, and nighttime, resulting in uncontrollable power generation.

[0003] In addition to solar energy, environmentally friendly power generation methods below 1kw can also use human power, wind power, hydropower and other methods. The power generation and energy storage system on the market mainly generates electricity through the generator to store electricity in the rechargeable battery. As shown in Figure 1, the power generation and energy storage system 1 below 1kw on the market mainly has a generator 11 electrically connected to the rechargeable battery 13 through a voltage stabilizing and current limiting circuit 12, and performs DC charging on the rechargeable battery 13. The voltage stabilizing and current limiting circuit 12 stabilizes and limits the power generated by the generator 11 to avoid the generator from being unable to operate smoothly due to excessive current when charging the battery 13, commonly known as "stuck", which causes the generator to be unable to work, charge or generate voltage. The unstable condition makes it impossible to charge. When the electric energy of the generator 11 passes through the voltage stabilizing and current limiting circuit 12, conversion loss will occur, which will relatively cause the power supply efficiency of the power generation and energy storage system 1 to be lost. In addition, when the rechargeable battery 13 is discharged, the rechargeable battery 13 also needs to convert DC into AC through an inverter 131. However, the use of the inverter 131 will cause a huge secondary loss of electric energy. In addition, the inverter 131 will also have power loss due to temperature rise, thereby causing discharge efficiency loss and electric energy loss. In addition, the inverter 131 also needs to be cooled by a fan heat dissipation device to avoid causing a dangerous temperature rise to the battery. Therefore, the heat dissipation of the inverter 131 will also consume energy.

[0004] Therefore, how to solve the above problems and deficiencies in the prior art is an urgent research and improvement direction for the inventors of the present invention and related manufacturers engaged in this industry.

DETAILED DESCRIPTION

[0045] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the power generation and energy storage system of the present invention with a generator power below 1Kw that does not require the use of a voltage stabilizing and current limiting circuit board, in conjunction with the accompanying drawings.

[0046] First, please refer to Figures 2 and 3, which are block diagrams and system diagrams of the power generation and energy storage system 2 of the present invention, which does not require a voltage-stabilizing and current-limiting circuit board for a generator power below 1Kw. It can be clearly seen from the figures that the power generation and energy storage system 2, which does not require a voltage-stabilizing and current-limiting circuit board for a generator power below 1Kw, includes a power generation device 3, a power device 4, and an energy storage device 5, wherein the power generation device 3 is electrically connected to the energy storage device 5, and the power device 4 contacts the power generation device 3.

[0047] Please refer to the aforementioned drawings and Figures 4 and 5, which are partial schematic diagrams of the inner cover 31 of the power generation and energy storage system 2 of the present invention, which does not require the use of a voltage-stabilizing and current-limiting circuit board for a generator power below 1KW, and partial schematic diagrams of the inner cover 31 and the stator assembly 316, wherein the power generation device 3 is provided with at least one inner cover 31. In this embodiment, the power generation device 3 is provided with two inner covers 31 of the same structure, and the inner cover 31 is formed of a non-magnetic composite material, and the inner cover 31 is formed with a plurality of outer partitions 311 at the outer periphery. The outer partitions 311 are arranged at intervals on the periphery of the inner cover body 31, and a hollow portion 3111 is formed in each outer partition 311, and the inner cover body 31 is provided with an outer rotor magnetic component 312 between each adjacent outer partition 311. The outer rotor magnetic components 312 are arranged at intervals on the periphery of the inner cover body 31, and the polarities of adjacent outer rotor magnetic components 312 are different. At the same time, the inner cover body 31 is also provided with an outer rotor magnetic component 313, which is arranged on the periphery of the outer partition 311 and adsorbs the outer rotor magnetic component 312.

[0048] At the same time, the inner ring of the inner cover 31 is formed with a plurality of guide parts 314 and an inner rotor assembly 315. The guide parts 314 are arranged at intervals on the inner ring of the inner cover 31, and the inner rotor assembly 315 is provided with a plurality of inner rotor magnetic parts 3151 and an inner rotor magnetic attraction part 3152. The inner rotor magnetic parts 3151 are respectively arranged between adjacent guide parts 314, and the adjacent inner rotor magnetic parts 3151 have different polarities. The inner rotor magnetic attraction part 3152 is arranged on the inner side of the inner rotor magnetic part 3151 and adsorbs the inner rotor magnetic part 3152. The rotor magnetic component 3151, and the number of the outer rotor magnetic components 312 is the same as the number of the inner rotor magnetic components 3151. At the same time, the inner rotor assembly 315 is formed with an axial hole 3153, and the axial hole 3153 has at least one pivot 3154. The pivot 3154 and the axial hole 3153 can be assembled or integrally formed. At the same time, further, the number of the outer rotor magnetic components 312 and the inner rotor magnetic components 3152 is equal, as shown in Figure 4, and the size of the outer rotor magnetic component 312 is larger than the inner rotor magnetic component 3152.

[0049] At the same time, the inner cover body 31 is provided with a stator assembly 316 between the outer rotor magnetic component 312 and the inner rotor assembly 315. The stator assembly 316 has a plurality of coil groups 3161. In this embodiment, the coil groups 3161 of the stator assembly 316 are three-phase winding groups, and the stator assembly 316 is covered by the inner rotor assembly 315. As shown in Figure 5, the stator assembly 316 is partially perspectively shown within the dotted line to show the inner rotor assembly 315 at the bottom.

[0050] The power generation device 3 also includes a carrier 32 and at least one outer shell 33. The carrier 32 and the stator assembly 316 are assembled together to fix the stator assembly 316. In this embodiment, the carrier 32 is locked in the locking hole 3162, and a linkage 321 is provided on the carrier 32. The two ends of the linkage 321 are respectively assembled with the shaft holes 3153 and the pivot 3154 of the two inner rotor assemblies 315. At the same time, a shell opening 331 is formed on one side of the outer shell 33, and the inner cover 31 is disposed in the outer shell 33.

[0051] At the same time, the power device 4 can be at least one of human power, wind power, and water power. In this embodiment, the power device 4 is a bicycle pedaled by human power, so the power device 4 is the wheel of the bicycle and contacts the linkage 321. If it is driven by wind or water power, the wheel of the bicycle can also be driven by wind or water power to rotate. Alternatively, as shown in Figure 7, an extension 3211 of the linkage 321 is provided with the power device 4, such as a fan blade, so that the wind or water power drives the power device 4 to rotate the linkage 321. When the power device 4 is started, the power device 4 rotates and drives the linkage 321, and the linkage 321 links the shaft hole 315 of the inner cover 31. 3 and the pivot 3154 rotate the inner housing 31. When the inner housing 31 rotates, the outer rotor magnetic member 312 and the inner rotor magnetic member 3151 rotate relative to the stator assembly 316. The rotation of the outer rotor magnetic member 312 and the inner rotor magnetic member 3151 relative to the stator assembly 316 generates an electromagnetic effect, causing the stator assembly 316 to output current. Simultaneously, the generator 3 increases the magnetic flux through the arrangement between the inner rotor magnetic member 3151 and the outer rotor magnetic member 312. Furthermore, the coil assembly 3161 of the stator assembly 316 is a three-phase winding assembly, generating a stable current. Furthermore, the electromagnetic effect generates power below 1 kW. Therefore, the generator 3 generates power below 1 kW.

[0052] At the same time, the inner cover 31 is made of a non-magnetic composite material, which can reduce the influence of the magnetic field on the generator 3 during rotation (the existing technology usually uses metal and magnetic materials, such as silicon steel, which generates a larger magnetic field). This arrangement allows the power device 4 to rotate without expending too much force, and can convert smaller kinetic energy into electrical energy.

[0053] Moreover, the inner cover 31 is formed of a non-magnetic composite material, which can significantly reduce weight compared to a rotor shell formed of a metal material, thereby reducing pedaling force and improving rotation efficiency and power generation efficiency. Moreover, each outer partition 311 of the inner cover 31 is respectively formed with the hollow portion 3111. The provision of the hollow portion 3111 can also reduce the weight of the inner cover 31, thereby improving its overall weight and improving rotation efficiency and power generation efficiency.

[0054] In addition, the energy storage device 5 is electrically connected to the power generation device 3, and the energy storage device 5 can set its output voltage to a DC voltage of 90V~240V. Therefore, the electric energy generated by the power generation device 3 can be directly stored in the energy storage device 5, and there is no need to set a voltage-stabilizing and current-limiting circuit between the power generation device 3 and the energy storage device 5, wherein the voltage-stabilizing and current-limiting circuit can be a voltage-stabilizing and current-limiting charging circuit, a voltage-stabilizing and current-limiting charging module or a voltage-stabilizing and current-limiting charging circuit board, that is, the energy storage device 5 does not need to pass through the voltage-stabilizing and current-limiting circuit, so the electric energy generated by the power generation device 3 can be completely stored in the energy storage device 5, thereby, the electric energy of the power generation device 3 will not be consumed by the voltage-stabilizing and current-limiting circuit, thereby reducing the power consumption during charging to improve The charging efficiency is improved. At the same time, the energy storage device 5 is electrically connected to a load device 6 (as shown in Figure 6), and the energy storage device 5 can set its output voltage to a DC voltage of 90V~240V to supply power to the load device 6. The DC voltage output by the energy storage device 5 can eliminate the need for an inverter, so the electric energy output by the energy storage device 5 can be completely supplied to the load device 6, thereby achieving a secondary reduction in power consumption. There is no need to set up a heat dissipation device for heat dissipation of the inverter, which can reduce the power loss caused by the heat dissipation device to improve the power supply efficiency. Therefore, the charging and power supply system can effectively reduce the power consumption during charging and power supply, and improve the efficiency of the overall charging and power supply system.

[0055] In addition, after the outer partition 311 provided on the outer ring of the inner cover 31 is assembled with the outer rotor magnetic component 312, the outer partition 311 and the inner side of the outer rotor magnetic component 312 are circular, so that there is no gap between the outer rotor magnetic component 312 and another outer rotor magnetic component 312. When rotating, no airflow resistance will be generated between the rotor magnetic components 312 due to the gap. Therefore, when the inner cover 31 rotates, the above-mentioned setting can reduce the influence of the airflow resistance caused by the rotation and easily rotate, thereby achieving the effect of enhancing the power generation efficiency.

[0056] In addition, the inner ring of the inner cover 31 is formed with the guide portion 314, which is arranged in a V-shaped guide groove in this embodiment. In addition to spacing and fixing the inner rotor magnetic component 3151, the guide portion 314 can also guide and discharge the air in the inner cover 31 through the guide portion 314 when the inner cover 31 rotates, so as to dissipate the heat energy generated by the stator assembly 316. The heat energy discharged by the guide can also be discharged through the outer shell opening 331, thereby achieving the effect of improving the heat dissipation effect and enhancing the power generation efficiency.
