Application Number: JP,2022-043841
Category (FI): H01M10/48@P,H01M10/44@P
Stage: PROBLEM TO BE SOLVED: To shorten a period required to acquire self-discharge characteristics over the entire voltage range that allows use of a secondary battery.SOLUTION: An external load having a known load amount is connected to a charged secondary battery. An output voltage of a secondary battery is measured at two different times after connection of the external load. The self-discharge characteristics of the secondary battery is calculated on the basis of change characteristics of the secondary battery showing the change in discharge capacity with respect to the change in the output voltage of the secondary battery, a time between two points in time, an output voltage value at each of the two points in time, and the load amount of the external load.SELECTED DRAWING: Figure 1 (Grant)
