ABSTRACT:
A smart battery pack and a method for recognizing the battery type using the same. The smart battery pack includes at least one battery cell coupled to an external set via positive and negative electrode terminals. A timer circuit is coupled to the external set via a data terminal and is adapted to apply a predetermined timer circuit signal for a period of time when a predetermined signal is applied from the external set. A first switch is controlled by the timer circuit and applies electric power from the battery cell, and a register outputs a predetermined register signal causing a smart battery controller to output battery type information to the external set. The smart battery pack has only one data line between the smart battery pack and the external set (and one data terminal on each) facilitating communication between the devices while maintaining a reduced manufacturing cost.
