The through hole 132 penetrates the bottom wall of the accommodating groove 131. The plurality of bus bars 40 are located in the accommodating groove 131. The cover plate 50 is disposed on an outer wall surface of the case 10 and covers the receiving groove 131.

Thus, the product volume is reduced.

Specifically, referring to fig. 6 and 8, in one embodiment, the cylindrical battery cell 23 is vertically received in the positioning slot 121. The outer wall surface of the bottom of the housing 10 is recessed inward to form a receiving groove 131. The first pole 231 of the cylindrical battery cell 23 passes through the through hole 132 to enter the accommodating groove 131. The plurality of bus bars 40 may include a third bus bar 43. The third bus bar 43 may be connected to the first pole 231 in the accommodating groove 131, and thus, the first pole 231 and the third bus bar 43 may be integrated at the bottom of the housing 10, thereby improving the overall integration degree to reduce the product volume. By providing the cover plate 50 to cover the receiving groove 131, the integrity of the case 10 can be further improved and the first post 231 and the third bus bar 43 can be protected.

In this way, the temperature of the bus bar 40 can be reduced.

Specifically, referring to fig. 6, in one embodiment, the plurality of bus bars 40 may include a third bus bar 43. When current flows through the third bus bar 43, a certain current loss is formed and heat is generated. The accumulated heat may cause the temperature of the third busbar 43 and the cylindrical cell 23 to rise, resulting in fire safety hazards. Therefore, by filling the heat-conducting glue between the third bus bar 43 and the cover plate 50, the heat of the third bus bar 43 can be transferred to the cover plate 50, so that the heat is emitted to the surrounding environment through the cover plate 50 to achieve the effect of cooling the third bus bar 43 and the cylindrical battery cell 23. The cover plate 50 may be made of aluminum material, thereby providing a good heat transfer effect. Meanwhile, the shell 10 can also adopt materials with good heat transfer effects such as aluminum materials and the like so as to further transfer the heat of the cover plate 50 to the shell 10 and improve the cooling effect on the third busbar 43 and the cylindrical battery cell 23.

Referring to fig. 6, in some embodiments, the stored energy power source 100 further includes a seal ring 60. The sealing ring 60 seals the outer wall surface connecting the cover plate 50 and the housing 10.

In this way, installation or repair is facilitated.

Specifically, fig. 2, 8 and 9 show a schematic structure of the first case 13 in the embodiment in which the battery cell 20 is a cylindrical battery cell 23. Fig. 10 shows a schematic structure of the first case 13 in an embodiment in which the battery cell 20 is a soft pack battery cell 21 or a square case battery cell 22. Referring to fig. 1, 2, 8, 9 and 10, in one embodiment, the housing 10 may include a first case 13 at an upper portion and a second case 14 at a lower portion. In some embodiments, the first and second cases 13 and 14 may be located at front and rear or left and right portions of the case 10, respectively, or the first and second cases 13 and 14 may be distributed at two opposite corners of the case 10.
