APPARATUS AND METHOD FOR BATTERY ABNORMAL CONDITION PREDICTION, AND BATTERY MANAGEMENT SYSTEM PROVIDING SAME METHOD
The present invention relates to an apparatus and a method that detect an abnormal behavior of a battery, and a battery management system providing the same, and a battery abnormal condition prediction apparatus that detects an abnormal behavior of a battery according to the present invention includes: a receiving portion that receives information indicating a temperature value, a pressure value, and a gas concentration value respectively from a temperature sensor that measures a temperature inside a battery module, a pressure sensor that measures a pressure inside the battery module, and a gas sensor that measures a gas concentration inside the battery module; a comparison portion that compares the temperature value, the pressure value, and the gas concentration value with a first threshold value, a second threshold value, and a third threshold value, respectively; and a detection portion that determines that an abnormal behavior of the battery has occurred when the comparison result shows that the pressure value exceeding the second threshold value falls below the second threshold value or the gas concentration value exceeds the third threshold value, while the temperature value exceeds the first threshold value.
