Description

Technical Field

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

[0002] Battery energy storage systems store electrical energy by converting it into chemical energy using batteries, and then convert that chemical energy back into electrical energy when external power is needed. Containerized energy storage systems are a type of battery energy storage system. Using a container as a carrier, containerized energy storage systems integrate battery systems, battery management systems, environmental monitoring systems, and local monitoring systems. They feature high integration, good safety, and strong environmental adaptability, and are increasingly used in power supply, grid, and user applications. During use, battery energy storage systems require batteries to be fixedly connected to the system for charging. After charging, the batteries are removed. However, existing systems require manual removal of batteries, lacking a feature to automatically eject them, often resulting in battery jamming. Currently, there is a lack of battery energy storage systems that can automatically eject batteries. Summary of the Invention

[0030] Furthermore, cavities are provided on both the front and rear sides of the fixed box 301. The slide rails II 304 of the two unfolding devices are respectively fixedly connected to the two cavities. The slide rails II 304 are two cylindrical slide rails. Two circular holes II are provided on the connecting rod 305, and the slide rails II 304 are slidably connected in the circular holes II. Rotating shafts II are provided on both sides of the connecting rod 305. A shaft hole II is provided at the lower end of the push rod I 306, and the rotating shaft II is rotatably connected in the shaft hole II, allowing the two push rods I 306 to rotate around the connecting rod 305.

When the connecting rod 305 slides upward, it pushes the two solar panels 303 upward through the push rod I 306 and the support III 307, thus opening the solar panels 303 and allowing the battery to be removed from the top. When the connecting rod 305 slides downward, it pushes the two solar panels 303 downward to close through the push rod I 306 and the support III 307, thus closing the solar panels 303.

[0031] The following is in conjunction with the appendix Figure 1-8 In detail, the energy storage system also includes a louver frame 401, a rotating shaft 402, and window slats 403. The lower end of the fixed box 301 is fixedly connected to the louver frame 401, and the lower end of the louver frame 401 is fixedly connected to the box cover 102.

A gear 405 is fixedly connected to each rotating shaft 402. A rack 406 is provided on the push rod II 404, and the rack 406 meshes with the gear 405.

[0034] Furthermore, the louver frame 401 is provided with an opening I, and a push rod II 404 is slidably connected in the opening I. When the push rod II 404 slides upward, it drives the window leaf 403 to rotate and close through the gear 405 and rack 406. At the same time, the push rod II 404 pushes the connecting rod 305 to slide upward, completing the opening of the solar panel 303. This allows the louver to close and stop heat dissipation when charging stops. When the push rod II 404 slides downward, it drives the window leaf 403 to rotate and open through the gear 405 and rack 406. At the same time, the push rod II 404 pushes the connecting rod 305 to slide downward, completing the closing of the solar panel 303. This allows the louver to open for heat dissipation when charging starts, preventing battery damage caused by overheating.

[0035] The following is in conjunction with the appendix Figure 9-11 In detail, the energy storage system further includes a switch box 501, a bracket IV 502, and a slide rail III 503.

[0036] Furthermore, the switch box 501 serves as a support, providing support space for the bracket Ⅳ 502 and the slide rail Ⅲ 503.

[0037] The following is in conjunction with the appendix Figure 9-11 In detail, the energy storage system further includes a slider 504, a locking tongue 505, and a spring II 506. Two sliders 504 are slidably connected to the slide rail III 503, and a locking tongue 505 is fixedly connected to each of the two sliders 504. Two springs II 506 are slidably connected to the slide rail III 503, and the two springs II 506 are used to make the two sliders 504 have a tendency to slide towards the center.

[0038] Furthermore, slide rail Ⅲ503 is a cylindrical slide rail, and slider 504 is provided with a circular hole Ⅲ. Slide rail Ⅲ503 is slidably connected in the circular hole Ⅲ, so that slider 504 can slide on slide rail Ⅲ503.

[0039] The following is in conjunction with the appendix Figure 9-11In detail, the energy storage system also includes a button 507, a bracket V 508, a sliding rod 509, and a sliding groove 510. The button 507 is slidably connected to the switch box 501. The button 507 passes through the switch box 501 and the fixing box 301. The bracket V 508 is fixedly connected to the button 507. Sliding rods 509 are fixedly connected to both sides of the bracket V 508. The lower ends of the two sliders 504 are provided with sliding grooves 510. The two sliding rods 509 are slidably connected in the sliding grooves 510 located on the same side.

[0040] Furthermore, the switch box 501 has an opening II, and the fixing box 301 has an opening III. The button 507 is slidably connected in the openings II and III. The switch box 501 passes through the openings II and III and the fixing box 301. The bracket V 508 provides support and a fixed space for the sliding rod 509. The sliding groove 510 is located at the bottom of the slider 504. The sliding groove 510 is at a 45° angle to the button 507. When the button 507 is pressed, the button 507 slides through the bracket V 508. The lever 509 slides backward in the sliding groove 510. The sliding lever 509 pushes the two sliders 504 to slide away from the center through the sliding groove 510, so that the sliders 504 and the locking tongue 505 slide off the hook 512, thus unlocking the solar panel 303. At the same time, the two springs II 506 are compressed. When the button 507 is released, the two springs II 506 extend and push the two sliders 504 to slide towards the center. The sliders 504 are driven by the sliding groove 510 and the sliding lever 509.

[0041] The following is in conjunction with the appendix Figure 9-11 In detail, the energy storage system also includes a bracket VI 511 and a hook 512.

The hook 512 can be engaged with the locking tongue 505.

[0042] Furthermore, when the two solar panels 303 are closed downwards, the brackets VI 511 and hooks 512 on the two solar panels 303 engage the locking tongue 505, thus closing and locking the solar panels 303. At the same time, the solar panels 303 drive the linkage rod 305 to move downwards, which in turn drives the push rod II 404 to move downwards. The push rod II 404 pushes the lifting plate 105 downwards, compressing the spring I 106, thus lowering the battery and closing the blinds. When the button 507 is pressed to unlock the solar panels 303, the spring I 106 extends upwards, pushing the lifting plate 105 and ejecting the battery. The lifting plate 105 then drives the push rod II 404 and the linkage rod 305 upwards, thus completing the three functions of opening the blinds, opening the solar panels 303, and ejecting the battery.
