Embodiment 1

[0121] This embodiment 1 provides a battery cap that can be sleeved on the top cover 310 and / or at least part of the side shell 320 of the single battery 300 , so as to realize fast and stable structural connection between the single batteries 300 .

[0122] The single battery 300 described in this embodiment is a power battery with high energy density, including single cylindrical battery, square battery, etc. The single cylindrical battery can be selected from 18650 battery, 21700 battery, 46800 battery, etc., but Not limited to this.

[0123] like Figure 1-Figure 2 As shown, this embodiment provides a battery cap, including a structural connection unit, the structural connection unit includes a cap body 110 and a cap top 120 fixed thereto, the cap body 110 can be attached to the side shell of the single battery 300 320, the cap top 120 can be attached to the top case or bottom case of the single cell 300.

[0124] In a preferred embodiment, the cap top 120 includes cros...

Embodiment 2

[0133] A battery cap is provided in this embodiment. The battery cap includes a structural connection unit and an electrical connection unit. The features of the structural connection unit that have been included in Embodiment 1 are naturally inherited in this embodiment.

[0134] according to Figure 3-Figure 4 , in this embodiment, the electrical connection unit includes a conductor connector 210, the conductor connector 210 is fixedly connected with the cap top 120, one end of the conductor connector 210 is used for electrical connection with a polar pole of the single cell 300, the conductor The other end of the connecting member 210 is used for electrical connection with the same polarity pole or different polarity poles of the adjacent unit cells 300 .

[0135] Preferably, the electrical connection unit further includes at least one insulating spacer 140. The insulating spacer 140 can be selected as an insulating sheet or an insulating block, and can not only be used for...

Embodiment 3

[0141] In this embodiment, a battery cap is provided. The battery cap includes a structural connection unit and an electrical connection unit. The features of the structural connection unit and the electrical connection unit that have been included in Embodiment 1 and Embodiment 2 are naturally obtained in this embodiment. inherit.

[0142] according to Figure 5-Figure 8 , In this embodiment, the electrical connection unit includes a conductor connection member 210 and a current sharing connection member 220 .

[0143] In a preferred embodiment, the current sharing connector 220 is a parallel short bus bar 223 for electrically connecting a pole of one polarity of a single cell with a pole of the same polarity of an adjacent single cell, such as Figure 11 .

[0144] In another preferred embodiment, the current equalizing connector 220 includes a second connection part 221 and a confluence part 222 , and the second connection part 221 is electrically connected to a polar pol...

Abstract

The invention relates to a battery cap, an easy-to-assemble single battery, a battery pack and a method for grouping in a single battery box; the battery cap includes a cap body and a cap top; the cap body is used to attach the side of the single battery The shell and the top of the cap are used to attach the top shell or the bottom shell of the single battery; the lower part of the cap body can be placed on at least part of the side shell of the single battery, and the upper part of the cap body is connected to the top of the cap; the cap The top includes at least one pressing down connecting strip and at least one fastening connecting strip. The pressing down connecting strip and the fastening connecting strip are arranged crosswise, and they are connected at the intersection; both ends of the pressing down connecting strip and the fastening connecting strip are outward. Extending beyond the outline of the cap body; the push-down connection strip and the fastening connection strip are used to securely connect with the push-down connection strip and the fastening connection strip of the adjacent battery cap. The battery cap and the single battery can be assembled into the above-mentioned easy-to-assemble single battery, and all structural sealing can be completed directly and quickly in the box, improving the efficiency of the assembly.

Description

Technical field [0001] The invention relates to the field of new energy power batteries, and in particular to a battery cap, an easy-to-assemble single battery, a battery pack, and a method of grouping the single battery in a box. Background technique [0002] The structural stability of the battery array after it is grouped in the battery box is composed of the structural stability between the single cells inside the battery array and the structural stability between the battery array and the battery box. At present, the main method is to set a pressing strip across the battery box above the battery array and lock it on the side wall of the battery box to press the shoulders or tops of several single cells that the pressing strip passes through. To achieve downward pressure on the single cells in the path, so as to reduce the displacement in the Z-axis direction under vibration; multiple downward pressure strips cover all the single cells in the battery array, locking the s...
