BATTERY PACK AND CHARGING METHOD THEREOF

摘要

A charging method of a battery and a battery pack thereof are described. A fully charged amount of the battery cell is changed upon comparing the charge amount of the battery to a reference capacity. If the battery cell is fully charged, charging of the battery cell may be interrupted and a counter incremented. The charged amount of the battery cell is compared to a reference capacity, and if the charged amount of the battery cell is equal to the first reference capacity, the fully charged amount of the battery cell may be set to another reference capacity, and the battery discharged the battery cell down to the new reference capacity.

主权项

1. A method for charging a battery comprising:
determining whether a battery cell is fully charged; if the battery cell is fully charged, interrupting charging of the battery cell; determining whether the charged amount of the battery cell is equal to a first reference capacity; if the charged amount of the battery cell is equal to first reference capacity, incrementing a stored number of interrupted charging counts; determining whether the number of interrupted charging counts is equal to a preset number; if the number of interrupted charging counts is equal to the preset number, setting a fully charged amount of the battery cell to a second reference capacity; and discharging the battery cell down to the second reference capacity.
