Problems solved by technology

In the absence of special testing methods and testing equipment, when evaluating the bending strength of a battery, those skilled in the art usually rely on their own experience to make judgments, which is highly subjective, and the evaluations made by different technicians on the same battery not comparable

Abstract

The invention discloses a method for detecting the bending strength of a battery. The method comprises the following steps: firstly, supporting a battery to be detected by two supporting points with the span of L; then applying a load P to a middle position between the two supporting points along the direction which is vertical to the surface of the battery to be detected; recording the size P1 of the load P when the battery to be detected has the deformation with the route a or recording the size P2 of the load P when the battery is damaged; and finally, substituting obtained data into a formula to calculate the value of the bending strength to realize the aim of quantitatively detecting the bending strength of the battery. With the adoption of the method disclosed by the invention, a specific numerical value for evaluating the bending strength of the battery can be obtained; a detection result is objective and the different detection results have the comparability. The invention further provides a device for detecting the bending strength of the battery.

Description

technical field [0001] The present invention relates to the technical field of battery detection, more specifically, to a method for detecting the bending strength of a battery, and also to a device for detecting the bending strength of a battery. Background technique [0002] Batteries are one of the essential components in portable electronic devices. Guided by consumer demand, the thickness of portable electronic devices is becoming thinner and thinner, which requires the batteries installed in the devices to be thinner as well. [0003] After thinning, the battery is more prone to bending and more likely to break after bending. Based on the consideration of ensuring the safety performance of the battery, it is very necessary to add the evaluation of the bending strength of the battery during the testing process. [0004] Since the battery itself has a certain internal structure and is heterogeneous, the existing methods and devices for testing the bending strength are ...
