Embodiment Construction

[0057] The following is attached Figure 1-Figure 2 The application is described in further detail.

[0058] The embodiment of the present application discloses a thermal runaway data acquisition method of a lithium-ion battery, referring to Figure 1-Figure 2 ,include:

[0059] S1. The lithium ion battery 1 is placed in the heating carrier 2 .

[0060] S2, heating the lithium-ion battery 1 by the heating device 3 .

[0061] S3. If the collection device collects the sign information of thermal runaway of the lithium-ion battery 1 , the collection device sends a thermal runaway occurrence signal to the controller 7 .

[0062] S4. After receiving the thermal runaway signal, the controller 7 judges that the current lithium-ion battery 1 is in a thermal runaway state, and sends an activation signal to the exhaust device 5 .

[0063] S5. The air extraction device 5 extracts the gas in the heating carrier 2 to the outside after receiving the start signal.

[0064] S6. The gas a...

Abstract

The invention relates to the technical field of battery detection, in particular to a thermal runaway data acquisition method of a lithium ion battery and an acquisition analysis system of the thermal runaway data acquisition method. The heating device heats the lithium ion battery, the collecting device collects mark information of thermal runaway, the collecting device sends a signal to the controller, and the controller judges that the lithium ion battery is in a thermal runaway state at present, sends a starting signal to the air extracting device and extracts air in the heating carrier outwards after receiving the starting signal. The lithium ion battery thermal runaway monitoring device has the advantages that the lithium ion battery is heated to be in thermal runaway, the generated gas is collected to be analyzed and processed, and therefore the thermal runaway condition data of the lithium ion battery is obtained.

Description

technical field [0001] The present application relates to the technical field of battery detection, in particular to a thermal runaway data collection method of a lithium-ion battery and a collection and analysis system thereof. Background technique [0002] With the development of science and technology, the demand for power supply batteries is also increasing with the increase of electrical equipment. Lithium-ion batteries are the main type of batteries for electrical equipment. In addition to smart mobile devices such as mobile phones, tablet computers, and laptops, lithium-ion batteries are required. In addition, there are vigorously developed new energy vehicles that require the application of lithium-ion batteries. [0003] In recent years, in order to achieve a longer cruising range of new energy vehicles, there is a higher requirement for the energy density of lithium-ion batteries, and the greater the energy density, the more safety issues lithium-ion batteries will...
