A battery control system (1) controls a solid-state battery including a battery cell (21) having a solid electrolyte and a negative electrode containing lithium. The battery control system includes: a measurement unit that measures a surface pressure distribution from an actual measured value or an estimated value of a surface pressure distribution on a main surface of the battery cell (21); and a control unit that controls a charge / discharge current of the solid-state battery, the charge / discharge current being at least one of a charge current and a discharge current. The control unit determines the charge / discharge current according to an upper-limit surface pressure difference and a lower-limit surface pressure difference, the upper-limit surface pressure difference being a difference between a measured value of the surface pressure distribution measured by the measurement unit and an upper limit surface pressure of the battery cell (21), the lower-limit surface pressure difference being a difference between the measured value of the surface pressure distribution measured by the measurement unit and a lower limit surface pressure of the battery cell (21).
