Description

Technical Field

[0001] This invention relates to the field of energy storage battery technology, and specifically to a solar energy storage battery. Background Technology

[0002] Solar cells primarily operate based on the photoelectric effect of semiconductors. When sunlight shines on a semiconductor material, photons interact with electrons in the semiconductor, transferring energy to the electrons and causing them to transition from the valence band to the conduction band, thereby generating electron-hole pairs and forming an electric current.

[0003] To prevent overheating or overcharging, existing energy storage batteries often use a Battery Management System (BMS). This system monitors the battery's status, such as voltage and temperature. When the battery is nearing full charge, the BMS may switch charging modes, such as from constant current to constant voltage, and finally stop charging. Alternatively, it may intermittently replenish the charge after it is fully charged. However, current designs tend to completely stop charging and wait for the charge level to drop to a certain threshold before resuming charging. For example, laptops are typically set to stop charging above 95% and only resume charging when the charge level drops to 90%, avoiding frequent charging cycles.

[0004] While BMS technology prevents immediate battery damage, prolonged exposure to full charge (especially at high temperatures) still accelerates battery aging. Furthermore, the BMS system is expensive, typically accounting for 10% to 20% of the battery price. More importantly, when a battery is fully charged, its internal chemicals are in a higher energy state and more active. Maintaining this high-pressure state for extended periods accelerates electrolyte decomposition and electrode material degradation, leading to reduced battery life. Even when the battery is not charging, leaving it plugged in increases the risk of thermal runaway due to the device overheating. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figure 1 - Figure 11 A solar energy storage battery includes a body 1. The upper surface of the body 1 is provided with a first circular hole and a second circular hole. A sealing sleeve 2 is connected to the first circular hole. A pressure relief component is provided inside the sealing sleeve 2. An electrode cylinder 102 is connected to the second circular hole. A charging and discharging component is provided inside the electrode cylinder 102. When the internal gas of the main body 1 increases sharply due to overcharging or thermal runaway, the pressure relief component is triggered to lift up for emergency gas release, and the charging and discharging components are passively ejected at the same time as the gas release.

[0024] This invention features a pressure relief component that releases a small amount of gas generated inside the battery during operation, while simultaneously isolating it from particulate matter such as dust in the air. When the battery experiences a rapid increase in internal gas due to overcharging or thermal runaway, the pressure relief component is lifted by the large amount of gas generated to perform emergency gas release. Simultaneously, the charging and discharging components are passively ejected during gas release, causing the charging connector or other electrical appliances that are being charged to be disconnected in an emergency, thereby protecting the battery.

[0025] In a further embodiment of the present invention, the pressure relief assembly includes a sliding groove 201 disposed on the inner wall of the sealing sleeve 2, and a sliding strip 204 is slidably connected in the sliding groove 201. A limit ring 205 is fixedly connected to the lower end of the sliding strip 204, and a vent plate 203 is fixedly connected to the upper end of the sliding strip 204. A top cover 202 is connected to the upper end of the vent plate 203, and a microporous membrane 206 is disposed on the inner wall of the sliding strip 204.

[0026] Furthermore, the microporous membrane 206 is made of e-PTFE microporous membrane. Since the microporous resistance is much greater than that of gas molecules in the air and much smaller than that of ice, water, dust and other particulate matter, the microporous membrane 206 has waterproof, dustproof and breathable properties.

[0027] Furthermore, when the battery is working normally, a small amount of gas generated inside is discharged through the microporous membrane 206; when the battery experiences thermal runaway, the microporous membrane 206 ruptures, allowing the gas to be discharged rapidly.

[0028] Furthermore, the width of the vent plate 203 is greater than that of the sliding strip 204, so that the vent plate 203 abuts against the sealing sleeve 2, thereby creating a gap between the vent plates 203, allowing gas to pass through the microporous membrane 206 and be discharged from the gap.

[0029] Specifically, when the battery is overcharged, the microporous membrane 206 will not rupture, but the amount of gas that permeates is still too large. This causes the gas to push up the top cover 202, increasing the gap through which the gas can be discharged and thus increasing the gas discharge rate. In turn, while rapidly discharging the gas, the rupture threshold of the microporous membrane 206 is increased, preventing the microporous membrane 206 from rupturing randomly and requiring frequent replacement.

[0030] Furthermore, the diameter of the limiting ring 205 is larger than that of the sealing sleeve 2, so that the top cover 202 will not fall off when it is lifted.

[0031] In a further embodiment of the present invention, the charging and discharging assembly includes an insulating ring 401 slidably connected inside the electrode cylinder 102, and an electrode post 4 is slidably connected inside the insulating ring 401. The lower end of the insulating ring 401 abuts against a spring plate 402, and a spring spring 7 is connected to one side of the spring plate 402.

[0032] Specifically, during charging and discharging, the external connector extends into the electrode cylinder 102, pressing the insulating ring 401 to connect the external connector with the electrode post 4, thus making the circuit connected.

[0033] In a further embodiment of the present invention, the charging and discharging assembly further includes a release groove 103 disposed on the side wall of the electrode cylinder 102, and the elastic spring 7 is provided with a locking part 701, a first pop-out inclined surface 702, an actuating part 703 and a second pop-out inclined surface 704 from top to bottom, and the first pop-out inclined surface 702 and the second pop-out inclined surface 704 are both slidably engaged with the release groove 103, and the locking part 701 abuts against the upper surface of the release groove 103, and the actuating part 703 is locked with the release groove 103.

[0034] Furthermore, the elastic spring 7 has a first position and a second position. In the first position, it is in an unenergized state, and at this time, the elastic spring 7 is located inside the pole cylinder 102, and the locking part 701 is not in contact with the release groove 103; in the second position, it is in an energized state, i.e. Figure 3 as well as Figure 5 As shown, the trigger part 703 enters the release groove 103, and the locking part 701 abuts against and locks against the upper surface of the release groove 103.

[0035] Furthermore, the elastic spring 7 has a first unlocking method and a second unlocking method. The first unlocking method is passive unlocking driven by the pressure relief component: the pressure relief component presses against the trigger part 703, causing the trigger part 703 to be squeezed inward, thereby releasing the elastic force of the elastic spring 7, and then springing back into the interior along the first ejection inclined surface 702.

[0036] In a further embodiment of the present invention, the lower end of the elastic spring 7 is connected to a contact plate 403, the center of the spring plate 402 is provided with an actuation groove 404, the lower end of the pole post 4 is connected to a first contact post 5, the first contact post 5 is slidably engaged with the actuation groove 404, the upper surface of the contact plate 403 is connected to a second contact post 501, the first contact post 5 and the second contact post 501 abut against each other, a first actuation spring 502 is connected between the spring plate 402 and the contact plate 403, and the first actuation spring 502 is disposed on the surface of the first contact post 5 and the second contact post 501.

[0037] Furthermore, the first electrical contact post 5 is a columnar structure that is wider at the top and narrower at the bottom, with its uppermost part being wider than the trigger groove 404 and its lowermost part being narrower than the trigger groove 404.

[0038] Furthermore, the second unlocking method is active unlocking by actively pressing the connector inward: pressing the external connector causes the pole post 4 to be squeezed and slid inward, thereby causing the first contact post 5 to move downward, with its wide part abutting above the touch groove 404, which in turn causes the elastic spring 7 to be further compressed, causing the second pop-out inclined surface 704 to slide in the release groove 103, which in turn causes the touch part 703 to be further compressed and disengaged from the release groove 103 and enter the pole cylinder 102. Then, the connector is released instantly and no longer pressed, which causes the elastic force of the elastic spring 7 to be released instantly, so as to drive the touch part 703 back to the initial position to complete the unlocking.

[0039] In a further embodiment of the present invention, a first power-conducting cover 6 is connected to the lower end of the power-conducting plate 403, a first power-conducting post 601 is connected to the lower end of the first power-conducting cover 6, a second power-conducting cover 602 is disposed inside the second circular hole, a second power-conducting post 603 is connected to the upper end of the second power-conducting cover 602, the first power-conducting post 601 and the second power-conducting post 603 abut against each other, a second actuating spring 604 is connected between the first power-conducting cover 6 and the second power-conducting cover 602, and the second actuating spring 604 is disposed on the surface of the first power-conducting post 601 and the second power-conducting post 603.

[0040] Furthermore, the second power-on cover 602 is connected to the electrode plates inside the battery.

[0041] Furthermore, in the initial state, the first terminal 5 is separated from the second terminal 501, and the first energized terminal 601 is separated from the second energized terminal 603.

[0042] Specifically, when the external connector is connected, the charging and discharging components are pressed into the interior, so that the first terminal 5 abuts against the second terminal 501, and the first power post 601 abuts against the second power post 603, thereby forming a connected circuit for charging or discharging.

[0043] In a further embodiment of the present invention, a fixing block 3 is fixedly connected to the upper surface of the main body 1. The fixing block 3 is provided with a transmission hole 301. A transmission rod 306 is slidably connected in the transmission hole 301. A first limiting plate 304 is fixedly connected to one end of the transmission rod 306. A reset spring 305 is connected between the transmission hole 301 and the first limiting plate 304, and the reset spring 305 is disposed on the surface of the transmission rod 306.

[0044] In a further embodiment of the present invention, a second limiting plate 307 is fixedly connected to the other end of the transmission rod 306, and one side surface of the second limiting plate 307 abuts against the transmission hole 301. An actuating strip 308 is fixedly connected to one end of the second limiting plate 307, and the actuating strip 308 is adapted to the position of the release groove 103.

[0045] Furthermore, the first limiting plate 304 and the second limiting plate 307 serve to prevent the transmission rod 306 from moving excessively or resetting excessively.

[0046] In a further embodiment of the present invention, a transmission bar 302 is fixedly connected to one end of the first limiting plate 304, and a transmission inclined surface 303 is provided on the lower surface of the transmission bar 302, and the transmission inclined surface 303 is slidably engaged with the top cover 202.

[0047] Specifically, when the top cover 202 is lifted by the gas impact, the vertical movement is converted into the horizontal movement of the transmission rod 306 under the action of the transmission inclined plane 303.

[0048] Furthermore, the return spring 305 ensures that all structures quickly return to their original positions after the venting process is complete.

[0049] In a further embodiment of the present invention, a handle 101 is provided on one side surface of the body 1.

[0050] In this invention, during charging, the external photovoltaic panel converts light energy into electrical energy to charge the battery; during discharging, the external electrical connector is inserted into the battery for amplification. During charging and discharging, the operator inserts the external connector into the electrode cylinder 102 and presses the insulating ring 401, causing the elastic spring 7 to be compressed. This causes the elastic spring 7 to slide downwards along the first ejection inclined surface 702 until the contact part 703 enters the release groove 103. The locking part 701 abuts against and locks against the upper surface of the release groove 103 to fix the external connector. At the same time, the first terminal 5 abuts against the second terminal 501, and the first power-conducting post 601 abuts against the second power-conducting post 603, thereby forming a connected circuit for charging or discharging. When the battery is overcharged, a large amount of gas permeates through the microporous membrane 206, impacting the top cover 202 and causing it to be pushed upwards. This causes the sliding bar 204 to slide upwards along the sliding groove 201, increasing the exhaust gap to expel the gas. When the top cover 202 is pushed upwards, it contacts the transmission bar 302 and, under the action of the transmission ramp 303, causes the transmission bar 302 to slide outwards horizontally. This compresses the return spring 305, causing the transmission rod 306 to move, which in turn drives the contact bar 308 to move outwards, contacting the contact part 703 and continuously squeezing it. This causes the contact part 703 to be squeezed inwards, releasing the elastic force of the spring plate 7. The spring plate 7 then bounces back inwards along the first ejection ramp 702, no longer fixing the external connector. Furthermore, due to the released elastic force of the spring plate 7, it will also... The external connector is pushed away to prevent incomplete disconnection and adhesion to the internal terminal 4, thus preventing the battery from receiving further power, thereby improving battery life and reducing the risk of thermal runaway. When the connector is disconnected and charging is no longer needed, simply press the external connector to squeeze the terminal 4 inward, causing the first terminal 5 to move downward, with its wide part abutting the upper part of the trigger groove 404. This further compresses the elastic spring 7, causing the second ejector inclined surface 704 to slide in the release groove 103. This further compresses the trigger part 703, causing it to detach from the release groove 103 and enter the terminal cylinder 102. Then, the connector is released instantly, and the elastic force of the elastic spring 7 is released instantly, causing the trigger part 703 to return to its initial position to complete the unlocking and power disconnection.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
