Technical Field

[0001] The utility model relates to the technical field of power supply equipment, in particular to a portable power supply equipment with a fire extinguishing sticker. Background Art

[0002] With the development of electric vehicle technology, the concept of green environmental protection has been deeply rooted in people's minds, and electric vehicles have attracted more and more attention from consumers. However, due to the limitations of current battery technology and the construction of charging stations, the range of electric vehicles has always been a big problem, which has affected the promotion of electric vehicles. In order to solve the problem of electric vehicle range, people have invented car power banks, but this kind of power bank needs to charge the electric vehicle battery when the vehicle is parked.

[0003] The prior art provides a mobile electric vehicle endurance charging device, which sends a request for charging while driving to the battery management unit of the electric vehicle through the battery management system, so that both AC slow charging or DC fast charging can be performed anytime and anywhere, and charging while driving can be achieved. However, the battery pack in the prior art still uses lithium battery technology, which is easy to catch fire during vehicle driving and battery pack movement. Therefore, how to prevent the battery pack from catching fire and how to extinguish the fire of the battery pack in time is an urgent problem to be solved.

[0004] Existing patents provide some solutions, such as patent WO2024090924A1. This invention relates to a battery automatic fire extinguishing device, including: a battery pack having a plurality of battery modules installed therein; a fire extinguishing liquid tank arranged outside the battery pack and filled with a fire extinguishing liquid; and a plurality of fire extinguishing pipes, wherein the plurality of fire extinguishing pipes connect the fire extinguishing liquid tank to each of the plurality of battery modules, and connect the fire extinguishing liquid tank to the battery module where the fire occurs among the plurality of battery modules, so as to supply and spray the fire extinguishing liquid to the battery module where the fire occurs, so that when a fire occurs in the battery module, the fire can be extinguished immediately at an early stage, and large-scale fires and personal injuries can be prevented in advance. However, this invention is prone to problems such as cell offset in terms of portability, and the inventor believes that there is still a lot of room for improvement. Utility Model Content

[0005] In order to suppress thermal runaway and reduce the possibility of mutual squeezing, deformation, combustion and fire caused by battery collision, a portable power supply device with a fire extinguishing sticker is provided, which can prevent battery chain combustion, extinguish fire immediately and have good fire extinguishing effect.

[0006] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

The fire extinguishing sticker is applied to any surface of the partition plate and the anti-collision substrate, and the fire extinguishing structure is also attached to the inner surface of the box body.

[0008] Furthermore, the portable power supply device can be carried manually, and the power supply device can be used by cars or electric vehicles in emergency situations. In order to reduce the possibility of the power supply device shaking and colliding during the transportation process, which may cause the battery cells to be damaged and the metal lithium to come into direct contact with oxygen, causing violent combustion and explosion, an anti-collision matrix is ​​provided to buffer the battery cells during the transportation process, reduce shock, and reduce the possibility of the battery cells catching fire.

[0009] In the utility model, a partition plate is arranged in the middle of the box body, a plurality of groups of battery cells are arranged on both sides of the partition plate, and a plurality of through holes are opened on the partition plate.

[0010] Furthermore, the through holes on the partition are mainly used to connect the cells in series with wires to improve the overall utilization efficiency of the battery. At the same time, placing the wires inside the box is also conducive to saving space, avoiding the wires from getting tangled together, making subsequent replacement and maintenance more convenient. At the same time, the arrangement of the wires passing through the through holes improves the overall neatness of the device and avoids the problem of short circuits that may occur when the wires are tangled together after aging and damage.

[0011] In the utility model, the box body further comprises a frame unit, the partition plate is arranged at the center of the square frame unit, and the battery core is arranged in the frame unit.

[0012] Furthermore, the side panels and the horizontal panels frame the cells. After the cells are placed, the top panel can be covered to protect the entire battery pack. At the same time, the frame unit can divide the internal cells into multiple battery groups for subsequent replacement and maintenance. At the same time, the square hole design can promote air flow through the inner wall of the side panel, thereby taking away the heat of the cells attached to the surface of the side panel, further improving the service life of the battery pack.

[0013] In the utility model, the frame unit comprises at least two transverse plates arranged parallel to the partition plates and side plates vertically connected to the transverse plates, and a plurality of square holes are formed on the side plates.

When the fire extinguishing stickers with the above-mentioned coating are used, it can be achieved that when the perfluorohexanone fire extinguishing patch is exposed to a temperature of 80-130°C and / or an open flame environment, it can break and vaporize to release the fire extinguishing material to achieve the purpose of cooling and / or fire prevention and / or fire extinguishing, thereby suppressing thermal runaway, actively cooling, and actively extinguishing fires; in addition, the use of perfluorohexanone as a fire extinguishing agent greatly reduces the gasification loss of perfluorohexanone in the microcapsule under normal conditions, and has a long service life. It should be noted that perfluorohexanone quickly vaporizes after extinguishing the fire, is non-conductive, does not pollute the protected object, does not damage the battery cell and the chassis of the vehicle, can greatly reduce the loss, and can prevent other parts of the vehicle body from being damaged.

[0018] Furthermore, the fire extinguishing stickers can be set not only on the surface of the partition plate, but also at multiple locations inside the battery pack that come into contact with the battery cells.

At the same time, since the battery cells are installed in cooperation with the slot body, accidents in which the battery cells are offset due to radial forces can be avoided, and the position of the battery cells can be further limited to avoid shaking of the battery cells during movement, thereby colliding with each other and causing fire accidents.

[0024] Furthermore, through the action force of the first spring, the battery cell can be firmly fixed at the current position in a static state, which makes it convenient for relevant personnel to design the size of the battery cell and for relevant technicians to assemble the battery cell.

[0025] Compared with the prior art, the outstanding features of the utility model are: a fire extinguishing sticker is attached to the surface of the partition plate to achieve the functions of suppressing thermal runaway, active cooling, and active fire extinguishing. The battery cell is fixed in a specific position by providing a slot body and a partition bar to prevent it from colliding, squeezing, deforming, and catching fire.
