A lithium ion battery package assembly structure without parallel connection include a battery pack housing, Battery pack lumen, heat conducting medium, Cell holder and cell, A lumen of that battery pack is arrange inside the battery pack shell, A heat conducting medium is arranged below the inner cavity of the battery pack, An electric cell fixing frame is arranged above the heat conduction medium, an electric cell is arranged inside the electric cell fixing frame, an electric cell connector is arranged on one side of the electric cell, one end of the electric cell connector is connected withan assembly current collector, an upper end of the assembly current collector is connected with a current collector fixing frame, and a terminal is connected above the current collector fixing frame.The invention has the advantages of simple structure and novel design, can meet the requirements of different charging quantities through adjustment, is widely applied, avoids some inherent shortcomings of parallel cells, avoids the single battery area being too large by stacking and stacking, and is suitable for being widely popularized and used because the pole lugs of the two stacks are led out on the same side, and is convenient to be connected in series.
Description
technical field [0001] The invention relates to the field of lithium-ion battery pack assembly, in particular to an assembly structure of lithium-ion battery packs without parallel connection. Background technique [0002] At present, the lithium-ion battery module is mainly to connect multiple small-capacity lithium-ion batteries in parallel or in combination to obtain a large capacity, so as to meet the requirements of large-scale power sources. However, this battery module has many disadvantages. The parallel battery module has high requirements on the consistency of the battery cells. The overall battery module is affected by the performance of a single battery cell. By connecting several lithium-ion batteries in series, the number of small cells can be reduced. , to reduce the overall battery pack cost. In addition, when using a non-parallel structure, the size of a single battery cell is relatively large, and it is also necessary to consider the size of the standard b...
