  "textContent": "A purpose is to provide a nonaqueous electrolyte type lithium ion secondary battery system, a control method, and a vehicle using the system, arranged to prevent unevenness of a salt concentration distribution in an electrolyte, avoiding an increase in internal resistance, thus improving endurance of the nonaqueous electrolyte type lithium ion secondary battery. For a measuring time (S101 to S104), a charge threshold current Ic and a discharge threshold current Id are read out (S102) and a charge hysteresis value Cc and a discharge hysteresis value Cd are calculated (S103). The charge hysteresis value Cc and the discharge hysteresis value Cd are compared (S105). If the charge hysteresis value Cc is larger than the discharge hysteresis value Cd (S105: Yes), a current value on a charge side is limited (S106). To the contrary, if the charge hysteresis value Cc is equal to or smaller than the discharge hysteresis value Cd (S105: No), a current value on a discharge side is limited (S107).",
