Protective shell for lithium battery cell and use method thereof

Abstract

The invention relates to the technical field of power supply energy storage, in particular to a protective shell for a lithium battery cell and a use method thereof. The invention aims to solve the technical problems of general protection capability, small application range and inconvenient replacement of a battery cell. In order to solve the technical problems, the protective shell for the lithium battery cell and the using method of the protective shell are provided, the protective shell is composed of a base, a limiting mechanism and a fixing mechanism, after a first fixing base is sleeved with the protective shell, the battery cell can eject a second fixing base upwards, under the action of a second spring, a second fixing base can press the battery cell, therefore, fixation is performed; the protective shell is ingenious in structure, a baffle is installed on the protective shell, then a fixing strip slides downwards, then the baffle is fixed through a positioning bolt on a fixing plate and a positioning pin on a limiting plate, when the battery cell needs to be replaced, the baffle is detached, then a fixing bolt on an auxiliary fixing frame is unscrewed, then the auxiliary fixing frame slides, and then the battery cell is taken down for replacement.

Description

technical field [0001] The invention relates to the technical field of power supply energy storage, in particular to a protective casing for a lithium battery cell and a method for using the same. Background technique [0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from a battery that contains a protective circuit and a casing and can be used directly. The battery cell is divided into three types: an aluminum shell cell, a soft pack cell, and a cylindrical cell. kind. Usually mobile phone batteries use aluminum shell batteries, bluetooth and other digital products mostly use soft pack batteries, and laptop batteries use cylindrical batteries in series and parallel combination. For lithium battery energy storage and power supply industries, lithium iron phosphate and three The primary lithium battery is an energy storage medium, but the battery energy storage produ...

AI Technical Summary

Problems solved by technology

In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well resolved: 1. The device can only be used to protect a single cell, and cannot protect multiple cells at the same time; 2. The device has no adjustment ability and cannot be adjusted according to the height of the battery cell, so the scope of application is small; 3. The device is troublesome when replacing the battery cell, and the battery cell cannot be replaced without moving the position of the device
