The embodiment of the invention provides a same-side current collecting device, a battery module and an electric vehicle, and relates to the technical field of new energy. According to the same-side current collecting device, the positioning cover plate is mounted at one end of the single battery pack so as to position the negative electrode and the positive electrode of each single battery in thesingle battery pack, so that the positive electrode of each single battery is aligned with at least one positive electrode lug on the current collecting sheet; and the negative electrode of each single battery is aligned with at least one negative tab on the current collector, and then the positive tab and the negative tab included in the current collector are respectively connected with the positive electrode and the negative electrode of the positioned single battery. Thus, the single battery pack does not need to be overturned when the tabs and the electrodes are welded, a large amount ofwelding time is reduced, and meanwhile, as the tabs of the current collecting pieces are positioned and aligned with the electrodes of the single battery pack by the positioning cover plates, multi-target welding can be carried out, and the welding efficiency is further improved.
Description
technical field [0001] The present application relates to the field of new energy technology, in particular, to a current collector on the same side, a battery module and an electric vehicle. Background technique [0002] When the cells of the traditional power battery module are grouped, most of them use welding technology on both sides to realize the series and parallel connection between the cells. Tape-out welding is used to realize the series-parallel connection between multiple cells. [0003] There are some deficiencies in using this two-side welding technology to realize the series-parallel connection between batteries. For example, the power battery module needs to be flipped and repositioned during welding, which takes a long time; at the same time, the height of the power battery module after grouping, The weight is larger and the energy density is lower; at the same time, the number of parts required for grouping makes the cost higher. [0004] Therefore, at pr...
