Abstract

The invention provides a test device and a calculation method. The test device is used for detecting a to-be-tested battery, and comprises a sealing box which is provided with an accommodating cavity for accommodating the to-be-tested battery, wherein the to-be-tested battery can be fixed in the sealing box; a puncture device which is fixedly connected with the sealing box, and comprises a puncture component used for puncturing the battery to be tested, wherein at least part of the puncture component is movably arranged in the containing cavity; and a data acquisition device which can acquire gas information in the sealing box, and is electrically connected with the to-be-tested battery so as to acquire voltage information of the to-be-tested battery in the accommodating cavity. According to the test device, the difficulty in model selection of the pressure release valve of the battery in the prior art is overcome.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a testing device and a measuring and calculating method. Background technique [0002] Common commercial lithium-ion batteries usually adopt a variety of safety protection mechanisms, the most critical of which is to set a directional pressure relief explosion-proof valve on the battery. In the event of a severe electrical or thermal failure or a destructive mechanical failure, the pressure relief valve acts as a pressure relief channel to prevent catastrophic high temperature and pressure inside the battery. [0003] At present, for batteries of different sizes and chemical systems, there is still a lack of reliable evaluation methods and systems for the quantification of the diameter and cross-sectional area of ​​the pressure relief device required for thermal runaway release of gas under electrical, thermal, and mechanical abuse. [0004] Therefore, the safety reliability of the batt...
