It is generally believed that the cell with a high K -value should be abnormal, while the cell with a low K -value should be normal. Therefore, to prevent false detection, the imported OCV- K dataset of lithium-ion cells needs to be preprocessed. Firstly, sort all samples in the OCV- K dataset in descending order of K -value.
A solar meter, also known as a solar irradiance meter or pyranometer, is a device that measures the amount of solar energy or irradiance emitted by the sun.
