A battery management system, a battery pack, an electric vehicle and a battery management method are provided. The battery management system according to the present disclosure includes a sensing unit for detecting voltage, current, and pressure of the battery cell, a memory for storing first relationship data representing the relationship between OCV and SOC and second relationship data representing the relationship between pressure and SOC, and a control unit for determining a voltage value representing the detected voltage, a current value representing the detected current, and a pressure value representing the detected pressure, and determining a SOC estimation value of the battery cell at each set time. The control unit compares a previous SOC estimation value having the plateau section, and determines a current SOC estimation value by executing at least one of (i) a first SOC estimation value based on the voltage value, the current value and the first relationship data, and (ii) a second SOC estimation value based on the pressure value and the second relationship data.
