| abstract |
A method for determining completion of charge of a long-duration lithium ion secondary battery is provided. n A method for determining completion of charge a lithium ion secondary battery including one lithium compound having an olivine crystal structure as a positive electrode active material, and a graphite material as a negative electrode active material, includes: (S 1 ) charging the battery by an amount of electricity Xc in time Ti 1; (S 2 ) stopping the charging for time Yc after completion of (S 1 ), and measuring a battery voltage Vi 1 after the time Yc has passed; (S 3 ) charging the amount of electricity Xc in the time Ti 1 after completion of (S 2 ); (S 4 ) stopping the charging for the time Yc after completion of (S 3 ), and measuring a battery voltage Vi 2 after the time Yc has passed; and comparing Vi 2− Vi 1 with a predetermined voltage difference Vi 3 to determine that the charge has been completed when Vi 2− Vi 1> Vi 3, and determine that the charge has not been completed when Vi 2− Vi 1< Vi 3. |
