Document Type and Number:
WIPO Patent Application WO/2023/207404
Kind Code:
A1
Abstract:
A method for measuring an internal resistance of a battery, and a circuit for measuring an internal resistance of a battery, which relate to the technical field of batteries. The method comprises: determining the capacity range of a battery to be subjected to measurement (S1); according to the capacity range of said battery, determining measurement logic of said battery (S2); according to the measurement logic, acquiring a voltage and a current of said battery (S3); and according to the measurement logic, the voltage and the current, calculating an internal resistance of said battery (S4). That is, targeted internal resistance measurement is performed on a battery to be subjected to measurement, such that the accuracy of measurement for an internal resistance of said battery can be improved.
