METHOD AND APPARATUS FOR OBTAINING CONTACT RESISTANCE OF CELL STRUCTURAL MEMBER, DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2022/228284

A1

Disclosed in embodiments of the present application are a method and apparatus for obtaining the contact resistance of a cell structural member, a device, and a storage medium. The method for obtaining the contact resistance of a cell structural member comprises: using an electrochemical thermal model to correct charge/discharge voltage simulation curves and temperature simulation curves at different rates; simulating electrochemical heat generation under set working conditions by means of the corrected electrochemical thermal model; establishing an electrothermal coupling model and importing same into the electrochemical heat generation; loading the set working conditions on the electrothermal coupling model; adjusting the contact resistances at different welding positions to match the simulated temperature data of each test area with the measured temperature data; and in response to the simulated temperature data of the test area being matched with the measured temperature data, obtaining the contact resistance of the structural member.
