To provide a charge and discharge control method of a lithium ion secondary battery, a secondary battery system, and a hybrid automobile, capable of fully exhibiting the battery performance by controlling localization of Li ions in the lithium ion secondary battery having a positive electrode active material which performs two-phase coexisting charge and discharge.
In a method of controlling charge and discharge of the lithium ion secondary battery having the positive electrode active material which performs the two-phase coexisting charge and discharge, the lithium ion secondary battery 100 is used between a discharge-stop charging depth SOCD and a charge-stop charging depth SOCC, and the discharge-stop charging depth SOCD and the charge-stop charging depth SOCC are sequentially varied between a lower-limit charging depth SOCB and an upper-limit charging depth SOCT.
