Problems solved by technology

[0004] However, the test devices or equipment used in the above-mentioned battery tests have relatively single functions, and it is difficult to completely simulate the state and environment of the battery during actual use. The test obtains the state and environmental conditions of the battery under test when it catches fire or explodes, which wastes battery materials, and the test cost is high

Embodiment Construction

[0042] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0043] refer to Figure 1 to Figure 6b , a battery testing device according to a preferred embodiment of the present invention includes a supporting heating mechanism 1 and a pressure applying mechanism 2 .

[0044] Wherein, the battery under test (not shown) can be supported on the supporting heating mechanism 1 and heated by the supporting heating mechanism 1 so as to make the battery under test have a required testing temperature. By controlling the heating element (such as the electric heating plate 11 described below), the tested battery can have different temperatures.

[0045] The pressing mechanism 2 has a pressing element 21 (such as a pressure push p...

Abstract

The invention relates to the field of battery safety testing devices and discloses a battery testing device which comprises a supporting and heating mechanism (1) and a pressure applying mechanism (2), wherein the supporting and heating mechanism (1) is capable of supporting and heating a battery being tested, the pressure applying mechanism (2) comprises a pressure applying component (21) and a first pressure sensor (22), the pressure applying component (21) can be driven to move close to or move away from the supporting and heating mechanism (1) so as to extrude the battery being tested on the supporting and heating mechanism (1), and the first pressure sensor (22) can be used for measuring pressure applied via the applying component (21) on the battery being tested which is supported on the supporting and heating mechanism (1) when the pressure applying component (21) moves close to the supporting and heating mechanism (1), The battery testing device provided in the invention can be used for conducting many kinds of safety tests such as extruding, needling and the like on the battery being tested; performance parameters of the battery being tested can be obtained in a single test.

Description

technical field [0001] The invention relates to a battery safety testing device, in particular to a battery testing device. Background technique [0002] Batteries (including hot battery cells and battery packs, lithium-ion batteries, etc.) may be in different working environments during use, and thus exhibit different performances. For example, under extreme conditions such as high temperature and / or high voltage, overdischarge and overcharge may occur, which may damage the reversibility of the battery, or even directly cause the battery to explode, threatening the safety of users. Therefore, batteries usually require safety testing before being put into use. [0003] Traditional battery safety tests mainly include acupuncture, extrusion, impact, etc., that is, when the battery under test is fully charged, use steel nails, steel rods, extrusion equipment and other pressure elements or equipment to pierce, impact, and squeeze. Press the battery under test to observe whethe...
