摘要： A pressurizing system capable of actively varying and adjusting the pressure applied to a cell of an all-solid-state battery includes: a pressurizing mechanism provided to pressurize an all-solid-state battery and driven to adjust and vary the pressure applied to the all-solid-state battery; a driving device operated to drive the pressurizing mechanism; and a controller controlling the operation of the driving device so that the pressure to pressurize the all-solid-state battery can be adjusted and varied by the above pressurizing mechanism. When the all-solid-state battery is charged or discharged, the controller controls the operation of the driving device based on a pressure change rate so that the pressure for pressurizing the all-solid-state battery may be adjusted and varied according to the pressure change rate determined based on the state information of the all-solid-state battery.
