Battery pack and vehicle

Abstract

The invention discloses: a battery pack which comprises a tray, wherein a containing groove is formed in the tray, and a through hole is formed in the side wall of the containing groove; a battery array, wherein the battery array is arranged in the containing groove, the battery array comprises a plurality of batteries which are arranged in sequence, and an electrode terminal is arranged on the side, facing the through hole, of each battery; and an electric connecting piece, wherein the electric connecting piece is arranged in the accommodating groove and is connected with the electrode terminals of the at least two batteries, and the through holes can enable the electrode terminals and the electric connecting piece to be exposed. Therefore, the battery array can be firstly placed in the accommodating groove of the tray, and then the electrode terminal of the battery array in the accommodating groove and the electric connecting piece are connected together through the through hole in the tray, so that the connecting process of the electrode terminal of the battery array and the electric connecting piece does not need to be completed outside the tray, the assembling process of the battery pack can be reduced, and the technological process can be optimized.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack and a vehicle. Background technique [0002] With the development of science and technology and human consumption of traditional energy, new energy vehicles have gradually entered people's lives due to their high environmental protection. As the top priority of the development of new energy vehicle technology, battery pack technology is related to the future of new energy vehicle development. [0003] In the related technology, the battery pack of new energy vehicles first arranges several batteries in sequence to form a battery array, then welds the electrode terminals and electrical connectors of the batteries to realize the electrical connection between the batteries, and then welds the batteries after welding. The array is assembled by putting the array into the tray, but it is difficult to install the battery array into the tray after welding, and it is eas...

AI Technical Summary

Problems solved by technology

[0003] In the related technology, the battery pack of the new energy vehicle first arranges several batteries in order to form a battery array, and then welds the electrode terminals and electrical connectors of the batteries to form a battery array. The electrical connection between the batteries is realized, and then the battery array after welding is put into the tray for assembly, but it is difficult to install the battery array after welding into the tray as a whole, and it is difficult to move the battery array to the tray. During the internal process, the welding parts of the electrode terminals and the electrical connectors are prone to fall off and the electrical connectors are damaged, which increases the cost of manufacturing and affects the production and use of the battery pack.
