<P>PROBLEM TO BE SOLVED: To provide a smart battery device capable of more exactly estimating a charging time. <P>SOLUTION: The smart battery device includes an adapter, a switch, a battery pack, detection resistance, an analog pre-processing circuit, and an automatic adaptive control circuit. The switch is electrically connected with the adapter. The battery pack is electrically connected with the switch, and the detection resistance is electrically connected with the battery pack and the adapter. Additionally, the analog pre-processing circuit is electrically connected with the battery pack and the detection resistance, and an analog signal measured by the battery pack and the detection resistance is digitalized to obtain a digital signal. The automatic adaptive control circuit is electrically connected with the analog pre-processing circuit and the switch to receive the digital signal. Based on the digital signal, the switch is selectively turned on/off. <P>COPYRIGHT: (C)2012,JPO&INPIT |
