Abstract
In a battery pack, it is difficult that information on a contained battery of the battery pack, such as the accurate state of charge of the battery, is detected at an external equipment. A communication terminal which can communicate the state of charge of the contained battery to the external equipment is provided on the installation surface on which power supply terminals of the battery pack are provided or on the surface adjacent to the installation surface. This allows the corresponding electrodes or the like of the external equipment to be concentrated at one place, so that the space required to arrange the corresponding electrodes or the like is reduced, thus downsizing the equipment.
