摘要： A battery management system, a battery pack, an electric vehicle, and a battery charging time prediction method are provided. The battery management system includes a memory for storing a first charge reference map in which a total of M × N charge rates are recorded, a sensing unit for detecting voltage, current, and temperature of a battery, and a control unit for determining a SOC estimation value of the battery. The control unit determines a mth charge rate associated with a mth SOC section to which the SOC estimation value belongs and a temperature section to which the temperature detection value belongs, from the first charge reference map. The control unit determines a predicted charging time value in the mth SOC section, based on the mth charge rate and a SOC difference between the SOC estimation value and an end point of the mth SOC section.
