ABSTRACT:
An intelligent battery device comprises the battery pack and the battery management device. The battery pack includes a battery group which is chargeable and dischargeable and a thermistor which detects and outputs the temperature of the battery group. The battery management unit, after receiving power and temperature signal from the battery pack between the battery pack and a host equipment, transfers power and information about the remaining capacity and deterioration of the battery to the host equipment and then transfers power supplied from the host equipment to the battery pack. The separation of the battery pack and the battery management unit allows the users to avoid malfunction of the battery management unit and damage to the circuit substrate when the battery group leaks liquid from the inner part and overheats in a hot and humid climate, and to change only the battery pack without touching the battery management unit when the user would like to change the battery group, to thereby reduce the burden of the user.
