Problems solved by technology

[0003] The structures of the existing soft-pack power lithium-ion battery modules are tightly packed together. At present, the isolation protection between battery modules has poor anti-collision effect and poor heat dissipation effect. This kind of soft-pack power lithium-ion battery The assembly settings are unreasonable and need to be improved urgently

Abstract

The invention provides a battery module pressure-retention mounting structure. Heat conduction silica gel is respectively arranged on each of the left outer side and the right outer side of a batterymodule; a heat conduction aluminum plate is arranged between every two battery modules; the heat conduction aluminum plates are arranged between every two pieces of oppositely arranged heat conductionsilica gel, extend along a front end and a rear end respectively, penetrate through clamping grooves in insulating positioning brackets in length directions of side rods, and are used for performingpressure retention clamping of two side surfaces of battery modules through clamping of every two insulating positioning brackets. Due to adoption of the heat conduction aluminum plates and the heat conduction silica gel between the battery modules, a collision buffer function of the battery modules is achieved, meanwhile isolation protection of the battery modules is achieved, and the structure is good in collision prevention effect, good in heat radiation effect, good in security, capable of effectively preventing packaging deformation after long-term use of a soft package, relatively safe and reliable, in addition simple and compact, high in space utilization rate and reasonable in arrangement.

Description

technical field [0001] The invention relates to the technical field of installation of soft-pack lithium-ion batteries, in particular to a pressure-holding installation structure of a battery module. Background technique [0002] Soft-pack lithium-ion batteries are composed of positive and negative electrode materials, electrolyte, diaphragm, tabs and shells. In order for lithium-ion batteries to charge and discharge normally, the inner cavity of the battery must be vacuum-free. The tab is the part used by the battery to conduct electricity. One end of it is in the inner cavity of the battery, and the other end is exposed outside the battery. The positive electrode of the soft-packed lithium-ion battery uses an aluminum-to-nickel strip, and the negative electrode uses a pure nickel strip, which is convenient for soldering when the soft-packed lithium-ion battery needs to be installed with a battery protection board. The middle is attached with hot-melt tab glue, and the upp...
