Abstract: A electrode plate cutting method includes: obtaining an offset distance between a detection reference and a cutting position on an electrode plate; obtaining, based on the offset distance and a distance between the detection reference and a cutting device, an actual distance between the cutting position and the cutting device; and obtaining, based on the actual distance, a cutting time point for the cutting position to be conveyed to the cutting device, so that the cutting device cuts at the cutting position. Obtaining the offset distance between the detection reference and the cutting position of the electrode plate is equivalent to obtaining a deviation from the detection reference caused during transferring of the electrode plate.
