摘要
In the present invention, (1) a three-electrode cell having an anode, a cathode, and a reference electrode is prepared and charged with different charging currents, the SOC value when the cathode potential at the time of charging with each charging current reaches the reference value Measuring the value; (2) preparing a two-electrode cell having an anode and a cathode, and measuring the potential of the two-electrode cell at the SOC value measured in step (1); (3) using the potential of the two-electrode cells measured in step (2), creating a voltage map of the two-electrode cells corresponding to each SOC; And (4) creating a charging protocol using the created potential map, a method of establishing a charging protocol for a lithium secondary battery, and a battery management system having the charging protocol established by the method.
