Abstract
A battery pack 2 is detachably loaded with respect to an electronic equipment 1 through an electric connecting portion 3 to thereby deliver power. A CPU 2f of the battery pack 2 detects signal states of communication lines by using communication lines, e.g., data lines 3h, 3f and clock lines 3i, 3g for informing information between the battery pack 2 and the electronic equipment 1, whereby the battery pack 2 detects whether the battery pack is in the state electrically connected to the connecting portion of the electronic equipment 1 or in the state electrically detached from the connecting portion of the electronic equipment 1. Thus, the number of connecting terminals used in electrically connecting the battery pack with respect to the electronic equipment is reduced. As a result, miniaturization can be realized and there can result less unsatisfactory terminal contact.
