Description

Technical Field

[0001] The present invention relates to the field of high specific energy power batteries, and in particular to a high specific energy power battery that is easy to maintain and a maintenance method. Background Art

[0002] High specific energy power battery refers to a battery with a higher specific energy. This type of battery can store more energy in the same volume or weight. It is an important technical means to improve the range of electric vehicles. It generally includes lithium-ion batteries, lithium polymer batteries, lithium iron phosphate batteries and nickel-hydrogen batteries. In recent years, with the progress of material science and battery technology, the energy density of high specific energy power batteries has been continuously improved. For example, the use of new materials such as high-nickel positive electrode materials and silicon-carbon negative electrode materials can significantly improve the specific energy of batteries.

[0003] The patent application with publication number CN209150243U, a high specific energy power battery pack, relates to the technical field of electric vehicle power batteries, and includes a battery module. The battery module consists of a module shell and a soft-pack battery cell module installed inside the module shell. The soft-pack battery cell module consists of a plurality of soft-pack battery cells distributed side by side, each soft-pack battery cell is provided with a protruding battery cell ear at the upper end, the upper end of the module shell is open, and a long groove-shaped bayonet is provided on the side wall of the module shell, and the soft-pack battery cell module is installed in the module shell by a positioning mechanism. The utility model has a simple structure, improves the assembly efficiency of the battery pack, has a relatively compact structure, is light in weight, and has a low production cost.

[0004] Existing high-energy-density power batteries are generally used in groups, but they will be damaged as soon as they are used. Since the overall cost of the battery pack is relatively high, the damaged battery pack is generally replaced individually to ensure the battery life of the battery pack. When inspecting and replacing the existing battery pack, the battery pack casing needs to be disassembled, and then the damaged battery pack is disassembled. During installation, more fixed structures are set between the battery and the casing for stability, which makes the disassembly of the battery pack more troublesome. In addition, the battery packs are connected by wires. When disassembling and installing, the wires need to be disassembled and welded, which increases the cumbersomeness of battery pack maintenance and reduces the battery maintenance efficiency.

[0005] Therefore, it is necessary to invent a high specific energy power battery and maintenance method that is easy to maintain to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a high-energy-density power battery and maintenance method that are easy to maintain. By loosening the position of a fixing plate and adjusting the position of a supporting plate, both methods can separate the current contacts and the conductive contacts, thereby realizing the separate disassembly and maintenance of the battery pack and the disassembly and maintenance of the entire battery pack group, so as to solve the problem in the prior art that the disassembly and maintenance of the battery pack is cumbersome and affects the normal use of the remaining battery packs.

[0037] The fixing component 003 is disposed on the outer shell 001 and is used to fix the battery pack 103 .

[0038] Furthermore, in the above structure, the maintenance component 002 includes connection grooves 201, which are opened on the top of the shell 001, and the number of the connection grooves 201 is the same as the number of battery packs 103.

[0050] The battery pack 103 can be limited by the fixing frame 309 , and the battery pack 103 can be fixed by moving the supporting plate 304 up and down.

[0051] A method for repairing a high-energy-density power battery that is easy to repair, comprising the above-mentioned high-energy-density power battery that is easy to repair, and the specific processing steps are as follows:

[0052] S1: By rotating each set of screw rods 203, the screw rods 203 are disengaged from the screw holes 205. At this time, the conductive contacts 206 below the fixing plate 209 are disengaged from the current contacts 104, so that the corresponding battery packs 103 below can be pulled out of the fixing frame 309.

[0053] S2: By rotating the nut 307, the screw 303 and the threaded hole 306 are matched, so that the supporting plate 304 drives all the battery packs 103 to move downward, so that the current contacts 104 and the conductive contacts 206 are separated, so that all the battery packs 103 can be pulled out from the fixing frame 309, and conversely, each group of battery packs 103 can be fixed.

[0054] like Figure 1-9 As shown, when the battery pack 103 is damaged, the repair method is determined according to the damage of the battery pack 103. When the battery pack 103 is damaged over a large area and needs to be repaired and replaced, the nut 307 drives the screw rod 303 to rotate, so that the carrier plate 304 drives multiple groups of battery packs 103 to move, so that the battery pack 103 can be pulled out of the fixing frame 309. In this way, there is no need to disassemble and weld the additional copper sheet 208. When a separate replacement is required, it is only necessary to unscrew the screw rod 203 at the corresponding position from the screw hole 205. At this time, the fixing The plate 209 moves upward, thereby separating the current contact 104 and the conductive contact 206, so that the battery pack 103 at the corresponding position can be detached from the fixed frame 309. In this way, after the battery pack 103 is disassembled, it does not affect the normal operation of other battery packs 103. After the power is turned on, the remaining battery packs 103 can still continue to work. Through the above two methods, the battery pack 103 can be inspected and repaired, and the tediousness of the inspection and disassembly of the battery pack 103 is reduced. The battery pack 103 can also be disassembled according to actual needs to improve the efficiency of the inspection and disassembly of the battery pack 103.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
