Problems solved by technology

[0002] Whether the battery is safe and reliable depends not only on the quality of the battery cell, but also on whether the battery protection board can effectively protect it. The higher the requirements, the smaller and narrower the battery protection board will pass through a larger current under the condition of the ultra-thin mobile phone and the shape of the battery cell, the temperature rise will be relatively high, which will affect the service life of the battery and easily cause damage.

Abstract

The invention discloses a cell protection plate. The cell protection plate comprises a cell protection plate body and a rubber shell, wherein the cell protection plate body comprises a flexible boardregion and a rigid board region, the flexible board region is divided into a first flexible board region and a second flexible board region, one side end of the first flexible board region is connected to one side end of the second flexible board region, the rigid board region is in lamination connection with the second flexible board region to form a flexible-rigid region, the rubber shell wrapsthe flexible-rigid region, and bulges are arranged on both of the first flexible board region and the second flexible board region. The cell protection plate has the beneficial effects that the wiringarea of a large-current copper foil is expanded, the internal resistance is reduced, the temperature rise is reduced, the cell protection plate is enabled to have an appropriate working temperature environment, the defects of narrow area and large heat generation quantity of the large-current copper foil before the invention are overcome, and the electrical property and the reliability of a product are improved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery protection plate. Background technique [0002] Whether the battery is safe and reliable depends not only on the quality of the battery cell, but also on whether the battery protection board can effectively protect it. The higher the requirements, the smaller and narrower the battery protection board will pass through a larger current under the condition of the ultra-thin mobile phone and the shape of the battery cell, the temperature rise will be relatively high, which will affect the service life of the battery and easily cause damage. Fault. Contents of the invention [0003] The main purpose of the present invention is to provide a battery protection board. In the case of ensuring that the size of the finished product after assembly is consistent with the original, the board width is increased on the body of the battery protection board, which can effectively reduce the ...
