Title:
BATTERY PULSE CHARGING/DISCHARGING MAXIMUM CURRENT ACQUISITION METHOD, APPARATUS AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/237476
Kind Code:
A1
Abstract:
The present application discloses a battery pulse charging/discharging maximum current acquisition method, apparatus and device, and a medium. The battery pulse charging/discharging maximum current acquisition method comprises: establishing an electrochemical-solid heat transfer coupling model for cells, and calibrating the electrochemical-solid heat transfer coupling model according to different curvatures of actual measured charging/discharging data of the cells; establishing a pulse model on the basis of the electrochemical-solid heat transfer coupling model, and calibrating the pulse model according to the actual measured pulse charging/discharging data; and predicting a pulse charging/discharging maximum current on the basis of the pulse model.
