| 主权项 | 1. A battery pack comprising: a secondary battery; and a protection device comprising: a measurement unit coupled to the secondary battery and configured to measure a temperature and a voltage of the secondary battery;a temperature estimation unit coupled to the measurement unit and configured to determine a temperature increasing rate of the secondary battery and estimate a future temperature of the secondary battery based on the temperature and the temperature increasing rate of the secondary battery;a memory unit coupled to the measurement unit and configured to store swelling condition data of the secondary battery, the swelling condition data comprising a first swelling condition and a second swelling condition; anda charging/discharging unit coupled to the secondary battery and configured to adjust a current or an input voltage applied to the secondary battery based on whether the future temperature and the voltage of the secondary battery correspond to the first swelling condition. | ||
