ABSTRACT:
A battery pack and a method of monitoring remaining capacity of a battery pack. With this method, two different procedures are used to estimate that remaining capacity. In a first procedure, data generated on the battery pack is used to estimate remaining battery capacity; and in the second procedure, data transmitted to the battery pack from a host device is used to estimate remaining battery capacity. The battery pack switches between these two procedures under defined conditions; and for example, with the preferred embodiment described in detail in the present specification, the battery pack switches from the first procedure to the second procedure when the battery current falls below a threshold value.
