Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power supply, and in particular to an energy balancing controller suitable for photovoltaic energy storage grid connection. Background Art

[0002] The photovoltaic storage grid-connected system is an integrated energy system that combines photovoltaic power generation and energy storage systems and is connected to the power grid through power electronic equipment. This system can effectively utilize solar energy, balance supply and demand through the energy storage system, improve the stability and reliability of the system, achieve efficient use of energy and stable operation of the power grid, and promote the large-scale application and sustainable development of renewable energy.

[0003] The main function of the energy balancing controller is to ensure uniform energy distribution between the various battery cells or battery modules in the battery pack, thereby improving the performance of the entire system, extending battery life and ensuring the safe operation of the system.

[0004] However, the existing energy balance controller has the following shortcomings:

[0005] The key to the speed of energy replenishment of photovoltaic cells depends on the external light intensity. The better the conditions, the shorter the charging time, and vice versa. The balancing controller mainly balances the parallel battery groups through the high-to-low mode, so it has the ability to transmit electric energy. When the photovoltaic system is operating in the summer, due to the good external light intensity, the power transmission amount is often lower than the input amount, and some battery groups will have overcharging problems. However, the existing equipment cannot release high-voltage energy, causing the battery overcharge energy voltage to far exceed the rated value, and directly impact the built-in control components of the equipment, damaging the voltage detection circuit and control circuit in the equipment, and ultimately leading to the paralysis of the photovoltaic system.

[0006] Because the equipment belongs to the category of electronic devices, it will produce certain energy loss and power leakage during its operation. The spillover energy will be attached to the surface of the shell. There is a risk of electric shock when personnel inspect. Traditional equipment often sets ground wires to build power transfer channels, but the processing range is limited and the risk probability is still in a high range.

[0007] Therefore, we propose an energy balancing controller suitable for photovoltaic and energy storage grid connection to solve the above problems. Summary of the invention

[0008] The present invention utilizes the device's own ability to detect voltage, and based on the reference standard value, obtains the energy storage status of each battery pack in real time.

To deal with the overcharge situation, the mechanical components can be coordinated to change the energy transmission line, changing transfer to release, in order to increase the battery pack discharge port and accelerate the release of energy stored in the overcharged battery pack, so as to solve the problems raised by the above-mentioned background technology.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please refer to the attached Figure 1 -Attached Fig. 9 As shown, the present invention provides a technical solution: an energy balancing controller suitable for photovoltaic energy storage grid connection, comprising a main shell 1, an inner lining plate 2 is fixedly installed inside the main shell 1, a front cover 3 and a rear cover 4 are respectively provided on the front and rear surfaces of the main shell 1, an integrated module 5 is fixedly installed on the front surface of the inner lining plate 2, a reinforcing outer plate 17 is fixedly installed on the rear surface of the front cover 3, and an isolation mechanism 35 is provided at the bottom of the main shell 1.

[0036] The effect achieved by the entire embodiment 1 is as follows: the input socket 8 is mainly used for energy input of each battery pack. On the one hand, it realizes real-time voltage detection of each battery pack, and on the other hand, it completes energy transfer of each battery pack. The number of input sockets 8 can be determined by the equipment specifications. During actual operation, each input socket 8 can be connected to a battery pack. During the process, the voltage value in each battery pack is detected in real time by the relevant components in the integrated module 5, and quickly analyzed and judged. When one or more numerical values ​​exceed the standard range, the connected mechanical components can be powered off to avoid high-voltage current directly impacting the relevant components in the integrated module 5, thereby achieving the effect of initial protection, reducing the probability of damage to each electrical component, and extending the service life of the equipment.

[0037] Embodiment 2, according to Figure 1 , Figure 4 , Figure 7 and Figure 8As shown, a group of locking seats 18 are fixedly installed on the rear surface of the reinforced outer plate 17, an external frame 19 is fixedly installed inside each locking seat 18, a second electric component 20 is fixedly installed inside each external frame 19, an extension frame 21 is fixedly sleeved on the axial end of each second electric component 20, a docking plug 22 is fixedly installed on one end of the outer wall of each extension frame 21, and an additional socket is fixedly connected to the rear surface of each docking plug 22, a group of adapter seats 23 are fixedly connected to the outer wall of the integrated module 5, a group of linear voltage stabilizing components 24 are fixedly installed on the front surface of the inner lining plate 2, a group of external frames 19, adapter seats 23 and linear voltage stabilizing components 24 are equal in number, a group of output sockets 31 are fixedly installed on one side of the outer wall of the main shell 1, an external guide seat 30 is fixedly connected to the outer wall of each adapter seat 23, a third insulating sheath 32 is fixedly installed on the outer wall of each external guide seat 30, a fifth copper guide piece 33 is fixedly connected to the inside of each external guide seat 30, and Each fifth copper guide plate 33 is respectively placed inside a corresponding third insulating sheath 32, the connection terminal of each output socket 31 is fixedly connected with a sixth copper guide plate 34, each fifth copper guide plate 33 is respectively connected with a corresponding sixth copper guide plate 34, the outer surface of each linear voltage regulator component 24 is fixedly installed with an insulating protective plate 25, the front surface of each adapter 23 is fixedly installed with a second insulating sheath 26, the output end of each adapter 23 is fixedly connected with a group of third copper guide plates 27, and each group of third copper guide plates 27 is respectively placed inside a corresponding second insulating sheath 26, a group of fourth copper guide plates 28 is fixedly connected inside each insulating protective plate 25, each third copper guide plate 27 is respectively connected with a corresponding fourth copper guide plate 28, the output end of each docking plug 22 is fixedly connected with a group of first flexible wires 29, and the output end of each group of first flexible wires 29 is respectively connected to the input end of a corresponding linear voltage regulator component 24.

[0038] The effect achieved by the entire embodiment 2 is as follows: this part of the components can cooperate with the mechanical components in the main shell 1. When one or more input sockets 8 are powered off, the docking plug 22 at the specified position can be quickly inserted deep into the additional socket to form a closed power transmission channel with the subsequent connected components. Since the linear voltage regulator component 24 has the ability to limit current, and the pre-processed battery pack is now in an overcharged state, the energy voltage is too large, and the introduced current intensity is high, so that the high-intensity current can be continuously transmitted to the limiting circuit in the linear voltage regulator component 24. The built-in adjustment elements such as MOSFET will automatically adjust the conduction degree according to the current detection result, control the current and voltage, and ensure that the current transmitted to the output socket 31 can be used by related electrical equipment. By using a two-way power transmission method, the energy in the overcharged battery pack is quickly consumed to achieve the purpose of high voltage release, thereby avoiding damage to the battery pack and equipment at the same time, causing paralysis of the photovoltaic system.

[0039] Embodiment 3, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, the isolation mechanism 35 includes a first rectangular frame 3501, the first rectangular frame 3501 is movably placed at the bottom of the main shell 1, an electromagnetic plate 3502 is fixedly installed inside the first rectangular frame 3501, a group of locking frames 3503 are fixedly installed at the bottom of the first rectangular frame 3501, an independent power supply 3504 is fixedly installed between the bottoms of a group of locking frames 3503, a group of second flexible wires 3505 are fixedly connected to the wiring terminals of the independent power supply 3504, and the output ends of the group of second flexible wires 3505 are all connected to the wiring terminals of the electromagnetic plate 3502, and L-shaped frames are fixedly installed on both sides of the outer wall of the first rectangular frame 3501 3506, a second rectangular frame 3507 is fixedly installed between the opposite sides of the two L-shaped frames 3506, the inner surface wall of the second rectangular frame 3507 is covered with an insulating sheath 3513, a lower shell 3508 is fixedly installed at the bottom of the main shell 1, a permanent magnet plate 3509 is fixedly installed inside the lower shell 3508, and the permanent magnet plate 3509 and the electromagnetic plate 3502 are vertically opposite to each other, and load-bearing brackets 3510 are fixedly installed on both sides of the rear of the first rectangular frame 3501, and an extended cross plate 3511 is fixedly inserted inside each load-bearing bracket 3510, and a group of adjustable feet 3512 is provided inside each extended cross plate 3511.

[0040] The effect achieved by the entire embodiment 3 is as follows: the opposing magnetic poles of the permanent magnet plate 3509 and the electromagnetic plate 3502 are the same. When the electromagnetic plate 3502 is energized, the physical property of mutual repulsion of the same magnetic poles can be used to lift the entire device, so that the device is suspended and locked inside the second rectangular frame 3507, while ensuring that the device body does not contact the second rectangular frame 3507 and its connected components. During operation, the insulating sheath 3513 can fully isolate the leakage current of the device casing from being transferred to the connected frame, thereby isolating the device body. The load-bearing bracket 3510 expands the overall width of the device, greatly reducing the risk of accidental touch by relevant personnel and avoiding electric shock accidents.

[0041] The working principle of the entire mechanism is as follows: in the preparation stage, the device is first moved to the designated work area, and an appropriate amount of battery packs are selected according to the equipment specifications. The connected conductive plugs are deeply inserted into each input socket 8 in turn, and then each parallel external line is connected to the relevant port in the integrated module 5. Subsequently, through wiring, the integration of multiple battery pack harnesses is completed in turn. After assembly, the front cover 3 and the rear cover 4 are sequentially covered on the front and rear surfaces of the main shell 1 to complete the overall packaging of the device. The external line is connected to the main power supply of the device to provide energy for multiple electrical components therein. According to the number of output sockets 31, a corresponding number of energy storage devices are selected and connected to each output socket 31 in turn.

[0042] In the locking stage, the first rectangular frame 3501 and its connected components are moved to the target area, and each adjustable leg 3512 is operated synchronously to initially adjust the height of the first rectangular frame 3501 from the ground. The device connected with the wiring harness is moved so that it can be movably inserted into the second rectangular frame 3507 to ensure that the electromagnetic plate 3502 can be fully aligned with the permanent magnet plate 3509. After the device is powered on, energy is released by the independent power supply 3504 and then continuously transmitted into the electromagnetic plate 3502 by the second soft wire 3505. The magnetic intensity generated on its surface can be adjusted by adjusting the power of the independent power supply 3504. Based on the basic principle that magnets with the same poles repel each other, when magnetism appears on the surface of the electromagnetic plate 3502, an upward push trend can be generated on the permanent magnet plate 3509 and its connected components. As the power of the electromagnetic plate 3502 increases, the magnetic force increases accordingly. Finally, the main body of the device can be suspended above the first rectangular frame 3501, and part of the device area is covered in the insulating sheath 3513.

[0043] During the detection phase, when the equipment is running, the current in each battery pack is introduced into the integrated module 5 in real time through the input socket 8, and analyzed one by one. The energy storage state of the corresponding battery pack is determined according to the voltage performance value. If they are all within the standard range, the battery packs with higher voltages are processed step by step, and energy is transferred one by one to ensure the energy balance of each battery pack. If the voltage in some battery packs is higher than the standard value, the relevant system module controls the opening of the corresponding first electric component 13, so that its inner axis retracts into the cavity, and acts on the connected first insulating sheath 14, slowly withdrawing the conductive plug 16 from the energized shell 11. At the same time, the first copper guide plate 9 and the second copper guide plate 15 are completely detached, thereby limiting the energy in the connected battery pack from continuing to be input into the integrated module 5.

[0044] In the processing stage, after the energy transmission of some input sockets 8 is terminated, the system module opens the second electric component 20 at the designated position, extends its inner axis outward, and slowly drives the connected docking plug 22 to be deeply inserted into each additional socket in turn, so that a new current transmission channel can be constructed outside the device, and then the first soft wire 29 continuously introduces energy into the connected linear voltage regulator component 24 to limit the energy. The processed standard voltage and current are sequentially transmitted through the third copper guide plate 27, the fourth copper guide plate 28, the fifth copper guide plate 33 and the sixth copper guide plate 34 into a corresponding output socket 31, and the discharge of the overcharged battery pack begins to be accelerated. The consumed energy can be continuously transferred to the connected energy storage device. Combined with the original discharge of the battery pack, the release of internal energy can be accelerated to avoid the continuous increase of the internal voltage.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
