Problems solved by technology

In the battery module, there is a pole butt welding connection between the battery and the battery, and the welding forms a binary battery assembly. If the pole is directly welded to the pole, the overcurrent capacity will be insufficient. After the welding of each binary cell assembly is completed, the welding seam is located on both sides of the pole. There is a gap between the two welded poles, and a thin layer of air is filled in the gap. When the battery module shakes, arcing is very easy to occur ,
[0003] In the existing battery module, if the battery cells are directly welded between poles and poles, the welding will have the following problems: 1) There is no redundant space for the deformation of the battery binary components after use ; 2) The welding space is small, which is not conducive to manual welding or machine welding

Embodiment approach 1

[0040] A pole-column battery cover comprising a cover plate 1; a pole column 2 is disposed in a cover plate 1; a bus member 3 is disposed at the end surface of the pole column 2, the bus member 3 includes an overflow portion 31, a transition portion 32, and a connecting portion. 33. The connecting portion 33 is connected by the transition portion 32 at both ends of the overflow portion 31.

[0041] Due to the mode of direct welding between the electrical cells, when the electrical cell is used in the existing battery module, there is no redundant space without the use of the secondary component of the cell; and the welding space is small, both Not conducive to manual welding, is also not conducive to machine welding, so see figure 1 with figure 2 As shown, the bushing member 3 is disposed at the end surface of the pole column 2, satisfying the amount of overflow capability after the battery and the battery, and converts the welding between the pole column 2 and the pole column 2 ...

Embodiment approach 2

[0048] Unlike the embodiment: the transition portion 32 of the present embodiment includes a plurality of arc 321 sequentially connected. In this embodiment, see image 3 with Figure 4 As shown, the transition portion 32 is composed of arc 321, linear segment 322, and arc 321, but the present invention is not limited, and can be divided into two structures of the third embodiment.

[0049] Other structures are identical to the implementation, and details are not described here.

Embodiment approach 3

[0051] Unlike the second embodiment, see Figure 5 As shown, the arc 321 of the present embodiment is a quarter arc, and the two arc 321 and the linear segment 322 are tangent, and the welding size between the adjacent bushings 3 is W, which satisfies the relationship: W = H + T + M + 2R, where R is the radius of the arc 321, and m is the length of the linear segment 322, and H is the height of the pole column 2, and T is the thickness of the overflow portion 31. The transition portion 32 of the present embodiment includes a circular arc 321, a linear segment 322, and a circular arc 321, and the two arc 321 are tangered with the intermediate linear segment 322, and the arc 321 is a quarter arc. At the time, the length of the line segment 322 is the largest, and the height H of the polar column 2 is equal to the thickness T of the overflow portion 31, and K is the length of the transition portion 32 on the width direction Y, from M = K-2R, That is, K = M + 2R, the welding size betw...

Abstract

The invention belongs to the technical field of battery production and manufacturing, and particularly relates to a battery cover of a pole, which comprises a cover plate (1), a pole (2) arranged on the cover plate (1), and aconfluence piece (3). The confluence piece (3) is arranged on the end face of the pole (2), the confluence piece (3) comprises an overflowing part (31), a transition part (32)and a connecting part (33), and the two ends of the overflowing part (31) are connected with the connecting part (33) through the transition part (32) respectively. The contact area of the welding surface can be ensured, and the arc discharge phenomenon is avoided. In addition, the invention also discloses a power battery and a battery module.

Description

Technical field [0001] The present invention belongs to the technical field of battery production, and more particularly to a pole column battery cover, power battery, and battery module. Background technique [0002] Today, countries are vigorously developing green, high-efficiency secondary batteries. The lithium ion battery is used as a new secondary battery, with a large energy density and power density, high operating voltage, light weight, long-term, safe safety, green environmental protection, etc., in portable appliances, electric tools, large Storage, electric traffic power supply, etc. have broad application prospects. In the battery module, there is a pole-column-welded connection between the electrical cell and the battery cell, and welded the binary electrical core assembly. If the direct welding of the pole column and the pole column can cause insufficient overcurrent ability, in the module After the welding of each dual electrical core component is completed, the w...
