A charge/discharge control device for a secondary battery mounted on a vehicle includes a temperature sensor detecting a temperature of a battery and a control device setting a battery power charged to and discharged from the battery base on the temperature detected by the temperature sensor and the state of charge of the battery. The control device sets at least one of a first value, a second value and a third value to be increased as the battery temperature rises, the first value indicating the state of charge at the time of switching between charging and discharging of the battery, the second value indicating the state of charge at the time when the battery power charged to the battery reaches a limit value in the case where the state of charge falls below the first value, and the third value indicating the state of charge at the time when the battery power discharged from the battery reaches the limit value in the case where the state of charge exceeds the first value.
