IMPACT MEASUREMENT METHOD OF BATTERY AND BATTERY SYSTEM ADOPTING SAME

Discussed is a method for measuring an impact for a battery, which includes: storing a previous operation mode of a battery system in a first area of a memory; storing a current operation mode of the battery system in a second area of the memory; determining whether the previous operation mode and the current operation mode are the same as each other; storing a change flag in a third area of the memory as a first value when the previous operation mode and the current operation mode are different from each other; receiving an acceleration sensor signal from an acceleration sensor when the current operation mode is a sleep mode and the change flag is the first value; and receiving the acceleration sensor signal from the acceleration sensor when the current operation mode is not the sleep mode.
