Stacked series-parallel lithium battery cell fixing box

Abstract

The present invention relates to a stacked series-parallel lithium battery core fixing box, which can hold a plurality of lithium battery cores in a main frame, and then stack them between the main frames, and connect and fix them in series. , in order to improve the problem of the indirect solidity of each lithium battery cell unit in the prior art, and be more suitable for the environment prone to high vibration, in addition, through the pole piece structure on the front side of the stacked main frame Series or Parallel Requirement Proper series or parallel connection of electrode series can achieve the purpose of changing the series and parallel connection of electrodes with simple operation. In addition, it has the function of changing the number of lithium battery cells connected in series according to the power demand. .

Description

technical field [0001] The invention relates to a stacked series-parallel lithium battery core fixing box, in particular to a fixing box that can conveniently select series and parallel connections among multiple lithium-polymer batteries to improve integration and utilization benefits. Background technique [0002] With the advancement of science and technology, the demand for power supply for various power-consuming operating tools or electrical and electronic products continues to increase, and the safety and convenience of power supply are also key technologies. Therefore, lithium batteries with high power characteristics Molecular batteries have become one of the most important modes of power supply today. [0003] In the prior art, lithium-polymer batteries are divided into two types: columnar and plate-type. Plate-type lithium-polymer batteries are widely used in various industries because of their advantages of flat thickness. . [0004] In terms of the structure o...

Problems solved by technology

[0005] As mentioned above, if a plurality of lithium-polymer battery cells are arranged in a casing, there will be unsafe factors (such as power applications that are easily accompanied by vibrations such as locomotives, boats, etc.) during use. above), and its power is also fixed and limited, so it cannot be easily transferred, such as it cannot be easily transferred to other electric appliances that require a slightly higher power consumption volts, and the internal lithium-polymer battery core is damaged Difficult to disassemble and replace when damaged

[0006] However, if a plurality of small-unit lithium-polymer batteries are used to be connected in series, although the advantages of switching to other electric tools can be achieved by increasing the number of series connections, it is not easy to fix the assembly structure between each other, and it is even more difficult. It is easy to disconnect the connection due to shock, and the existing design method as mentioned above, in the actual application operation, it is not easy to connect the lithium polymer batteries of each unit in series and in parallel according to the situation. Combined use actually has its disadvantages, so looking at the foregoing, the inventor of the present invention conceived and designed a stacked series-parallel lithium battery cell fixing box, in order to improve the deficiencies of the existing technology, and then promote industrial development.
