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 battery protection board, which includes a battery protection board body and a plastic case. The battery protection board body includes a soft board area and a hard board area, and the soft board area is divided into a first soft board area and a second soft board area. board area, one side end of the first soft board area is connected to one side end of the second soft board area, the hard board area is press-fitted and connected to the second soft board area to form the soft-hard joint area, The plastic shell wraps the soft-hard joint area, and the first soft board area and the second soft board area are both provided with protrusions. The beneficial effects of the present invention are as follows: increase the wiring area of ​​high-current copper foil, reduce internal resistance, reduce temperature rise, and ensure that the battery protection board has a suitable working temperature environment; improve the narrow area and large heat generation of high-current copper foil before the invention disadvantages; improve the electrical performance and reliability of the product.

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 ...
