Abstract

The invention discloses an establishment method and device of a lithium ion battery acupuncture model. The method comprises the following steps: constructing to obtain a one-dimension electrochemicalmodel according to an electrode chemical reaction of the lithium ion battery; establishing a three-dimensional thermal model of the lithium ion battery according to the total heat produced by the lithium ion battery in acupuncture; and coupling the one-dimension electrochemical model with the three-dimensional thermal model through the temperature and the heat, thereby generating a lithium ion battery acupuncture model. The one-dimension electrochemical model and the three-dimensional thermal model are coupled so as to generate the lithium ion battery acupuncture model, thereby accurately outputting the battery internal and battery surface temperature distribution; the security design of the battery is convenient, and the aim of improving the lithium ion battery security is realized.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a method and device for establishing an acupuncture model of lithium-ion batteries. Background technique [0002] Lithium-ion batteries have the characteristics of high energy, low operating temperature range, long storage life, no environmental pollution, no memory effect, etc., and have been widely used in portable devices, scientific equipment, vehicles and satellite systems, but the current safety performance issues have restricted The development of lithium-ion batteries, especially the internal short circuit problem. [0003] Acupuncture test is the main method to detect the short-circuit safety performance of lithium-ion batteries. For the research on the safety of lithium-ion batteries, acupuncture can better understand the temperature distribution of lithium-ion batteries, thereby improving the design of lithium-ion battery cells. However, at present, the ...
