Problems solved by technology

[0003] Existing battery safety test methods mainly include acupuncture, extrusion, overcharge, overdischarge, etc., and the existing test methods are often destructive tests, which cannot be repeated
Moreover, the state of the battery during the test is quite different from the actual state, which cannot accurately reflect the actual working performance of the battery when it is subjected to acupuncture, extrusion, etc. in the actual working state.

Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] In order to facilitate the understanding of the technical solution provided by this application, the background technology involved in this application will first be described below.

[0051] The inventor found through the research on the traditional battery safety test that the traditional battery safety test is often a destructive test, which cannot be repeated, and is quite different from the actual state of the battery, which cannot provide reliable data for battery safety warnings in accordance with. However, dangerous conditions such as fire and explosion of batteries in actual work are often a gradual accumulation process, not a one-time direct damage.

[0052] Based on ...

Abstract

The embodiment of the present application discloses a battery safety testing method and device. By gradually increasing the extrusion index and performing normal work for a period of time, various indicators of the battery are detected to determine that the battery is in danger through changes in various indicators. state, to avoid damage to the battery caused by a one-time extrusion test, and to observe the various indicators of the battery after each extrusion in real time, which is more in line with the actual working state of the battery and improves the accuracy of the test.

Description

technical field [0001] The present application relates to the technical field of battery testing, in particular to a battery safety method and device. Background technique [0002] Lithium-ion batteries are increasingly used in communication, transportation, lighting and other fields. With their unique applicability and convenience, they are becoming more and more popular. However, the safety issues of lithium-ion batteries are becoming increasingly prominent. [0003] Existing battery safety testing methods mainly include acupuncture, extrusion, overcharge, overdischarge, etc., and the existing test methods are often destructive tests and cannot be repeated. Moreover, the state of the battery during the test is quite different from the actual state, which cannot accurately reflect the actual working performance of the battery when it is subjected to acupuncture, extrusion, etc. in the actual working state. Contents of the invention [0004] In view of this, the embodimen...
