Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0027] An embodiment of the present invention provides a cell connection strip, including a first cell welding part 1, a conductive connection part 2 and a second cell welding part 3, one end of the conductive connection part 2 is welded to the first cell part 1, and the other end of the conductive connection part 2 is connected to the second cell soldering part 3. The cell connecting strip can be formed into a sheet structure.
[0028] Preferably, the width of the conductive connection part 2 is smaller than (such as figure 1 ) or equal to (such as figure 2 ) the width of the first cell welding portion 1 and the width of the second cell welding portion 3 . Wherein, the length and width of the first cell welding part 1 , the conductive connection part 2 and the second cell welding ...

The invention discloses a battery connecting strip, a battery connecting structure and a battery combination. The cell connecting strip includes a first cell welding part, a conductive connection part and a second cell welding part, one end of the conductive connection part is connected to the first cell welding part, and the other end of the conductive connection part It is connected with the welding part of the second electric core. The present invention can use a cell connection bar to connect two cells, so it is more convenient to combine or adjust the number of cells according to the required capacity, and it can make the combination of cells more convenient. Flat and tight. Since the number of welding times is reduced, the internal resistance is correspondingly reduced, which avoids the problems in the prior art that the number of combined batteries is relatively limited due to excessive heat generation due to too many times of welding.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery cell connection bar, a battery connection structure and a battery assembly. Background technique [0002] In the large pouch battery for energy storage power, the battery capacity is usually increased by connecting multiple cells in parallel. This is very common in the new energy industry. This method involves the welding method of parallel connection of cells in large pouch batteries. However, the combined battery in the prior art has the problems of unevenness when multiple cells are connected in parallel, too many times of welding leads to excessive heat generation and potential safety hazards, and the number of cells is relatively limited. Contents of the invention [0003] The embodiment of the present invention provides a cell connection strip, a battery connection structure, and a battery combination to solve the problem of unevenness when multiple cells are...
