Title:
BATTERY MOISTURE CONTENT MEASUREMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/206455
Kind Code:
A1
Abstract:
Provided in the present application are a battery moisture content measurement method and apparatus, and an electronic device and a storage medium. The method comprises: performing measurement to obtain a capacitance measurement value of a battery to be subjected to measurement; and determining a first moisture content value of said battery according to the capacitance measurement value and a capacitance-moisture content relational model, wherein the capacitance-moisture content relational model is obtained according to a correspondence between sample batteries with different moisture content values and capacitance values of samples. In the present application, a correspondence between the moisture content of sample batteries and capacitance values of samples is pre-constructed, and the moisture content of a battery to be subjected to measurement is determined according to the correspondence and a capacitance value of said battery, thereby reducing a step of manually cutting an electrode plate, and improving the efficiency of battery moisture content measurement.
