    摘要： A diagnosis device and method for diagnosing whether a component included in a battery system fails, according to an embodiment of the present invention, monitor, on the basis of abnormal state data on the component, whether an abnormal state of the component occurs, measure a maintenance time of an abnormal state when the abnormal state occurs in the component, so as to compare the maintenance time and a preset reference time, check, on the basis of the maintenance time, whether preset early diagnosis conditions are satisfied if the maintenance time is less than the reference time, and determine, on the basis of whether the early diagnosis conditions are satisfied, whether the component fails, and thus provided are a high-performance, high-precision, high-efficiency and high-reliability diagnosis device and method, which diagnose early whether a failure has occurred so as to preemptively respond even to temporary abnormal state data that is less than the preset reference time.

    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 m th charge rate associated with a m th 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 m th SOC section, based on the m th charge rate and a SOC difference between the SOC estimation value and an end point of the m th SOC section.
