Problems solved by technology

[0004] 1. The installation of the lithium-ion battery shell with the above structure is relatively complicated, especially the connection operation of the input and output circuits located on the top of the battery body is relatively difficult, resulting in low assembly efficiency and complicated assembly
[0005] 2. In addition, when it is applied to a high-rate battery pack, the high-rate battery pack is discharged with a large current (the current reaches 100-200A), and the shell in the prior art is used. Due to the high current of the battery pack during the user's use Discharge, the temperature of the battery pack rises sharply, the plastic shell cannot effectively dissipate heat, resulting in the temperature being kept inside the plastic shell, and the temperature cannot be transmitted to the outside of the plastic shell as soon as possible; the battery pack is discharged under high current and high temperature for a long time, which is highly harmful to lithium ions. The life of the battery pack is greatly affected

Abstract

The invention relates to the field of lithium batteries, and discloses a lithium-ion battery pack easy to install. The lithium-ion battery pack is characterized by comprising a battery cell body and a housing, wherein the housing is packaged outside the battery cell body. The battery cell body is packaged in a side shell, and a bottom plate is packaged at the bottom of the side shell. A top plastic piece is fixedly arranged at the top of the side shell, and the rear cover plate of the plastic piece is packaged at the side opening part of the top plastic piece. Each top pillar of the top plastic piece is inserted into each hole position of the side shell, and the bottom edge of the top plastic piece is jointed with the top edge of the side shell. An output interface piece and an input interface piece are arranged on the top plastic piece and on the inner side of the side face, directly facing the side opening part of the top plastic piece, and the output interface piece and the input interface piece are fixedly arranged on a switching plate through circuits respectively. The switching plate is electrically connected with the input circuit and the output circuit of the battery cell body respectively. Each top pillar of the rear cover plate of the plastic piece is inserted into each hole part of the top plastic piece, and the rear cover plate of the plastic piece is packaged at the side opening part of the top plastic piece.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to an easy-to-install lithium ion battery pack. Background technique [0002] At present, the lithium-ion high-rate battery pack industry uses plastic casings to assemble and assemble battery packs. The structure of the plastic casing is mainly composed of a cover plate and a cavity with one side open. When assembling, the battery core is first placed in the cavity. Then, the input circuit and the output circuit of the electric core body are respectively electrically connected to the input interface part and the output interface part fixed on the cavity, and then the cover plate is packaged on the opening of the cavity. [0003] In the process of researching the present invention, the inventor finds that the prior art has at least the following defects: [0004] 1. The installation of the lithium-ion battery shell with the above structure is relatively complicated, especially t...
