Title:
METHOD AND DEVICE FOR CATHODE PROTECTION DURING BATTERY CYCLE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/056690
Kind Code:
A1
Abstract:
A method for cathode protection during a battery cycle, comprising the following steps: obtaining a cathodic polarization resistance of a battery at different states of charge during an n-th charge and discharge cycle (S1); obtaining a cathodic open-circuit voltage of the battery at different states of charge, and a cathodic limit potential of the battery (S2); and calculating, according to the cathodic open-circuit voltage, the cathodic limit potential and the cathodic polarization resistance, the maximum charge current of the battery at different states of charge during the n-th charge and discharge cycle (S3). A device for cathode protection and a storage medium are used to implement the method for cathode protection, and can provide a reference limit current during battery charging.
