Embodiment 1

[0025] Embodiment 1: A kind of weld-free combined battery pack (see attached figure 1 To attach image 3 ), including a number of assemblies 1 connected together. In this embodiment, there are two groups of assemblies. The assembly includes an upper cover 2, a lower cover 3, and several groups of battery cells 4 installed between the upper cover and the lower cover. Each Four sets of battery cells are arranged in a combination, and the upper cover and the lower cover are closely connected together. Fastening screws 5 are connected to the battery pack, and the fastening screws fasten the upper cover and the lower cover of the assembly and the two adjacent assemblies together. A fastening screw is connected to the four corners of the battery pack. Between the upper cover and the lower cover of the two adjacent assemblies is connected the connecting piece assembly 6 for conducting the battery unit, between the upper cover of the assembly at the upper end of the battery pack and...

Embodiment 2

[0028] Embodiment 2: A kind of weld-free combined battery pack (see attached Figure 4 to attach Figure 6 ), its structure is similar to that of Embodiment 1, the main difference is that in this embodiment, between the upper cover and the lower cover of two adjacent assemblies and between the upper cover and the lower cover of the same assembly through the tongue 25 and the card Slot 26 is engaged. An extension plate 27 is arranged on the upper cover of the same assembly, a card slot is arranged on the extension plate, and a tab is arranged on the lower cover. In the two adjacent assemblies, the lower cover of the upper assembly is provided with an extension plate, and the upper cover of the lower assembly is provided with tabs.

[0029] The assembly columns above all the battery units are connected together by the upper pull plate 28 to form a whole, the assembly columns below all the battery units are connected together by the lower pull plate to form a whole, and the upp...

Abstract

The invention discloses a welding-free combined battery pack. The welding-free combined battery pack aims to overcome the defects that during assembling of a combined battery pack, spot welding needsto be performed on two poles of each battery and conducting plates, consequently, the risks of false welding and leak welding exist, product quality is influenced, process steps of spot welding are increased, and cost is increased. The welding-free combined battery pack comprises a plurality of combinations connected together, wherein each combination comprises an upper cover, a lower cover and aplurality of groups of battery units installed between the upper cover and the lower cover; each upper cover and the corresponding lower cover are closely connected together; connecting plate components used for conducting the battery units are connected between the upper cover and the lower cover of every two adjacent combinations; a plurality of conducting plates used for conducting the corresponding battery units are installed between the upper cover of the combination at the upper end of the battery pack and the upper ends of the corresponding battery units, and a plurality of conducting plates used for conducting the corresponding battery units are installed between the lower cover of the combination at the lower end of the battery pack and the lower ends of the corresponding batteryunits; and the conducting plates abut against electrodes of the battery units, and the connecting plate components abut against the electrodes of the battery units.

Description

technical field [0001] The present invention relates to a battery pack, more particularly, it relates to a welding-free assembled battery pack. Background technique [0002] The battery pack is generally composed of single cells connected in series and in parallel to meet various applicable occasions. Adjacent single batteries are generally connected with conductive sheets, and the positive and negative electrodes of the battery are connected with the conductive sheets by spot welding. There is a risk of false welding or missing welding during the welding process, resulting in product quality problems. Contents of the invention [0003] The invention overcomes the need to spot weld the two stages of the battery and the conductive sheet when assembling the combined battery pack, which has the risk of virtual welding and missing welding, which affects product quality, and increases the process steps of spot welding, which increases the cost. A welding-free combined battery ...
