摘要： The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).

摘要： In an electric power transmission device which transmits electric power between a primary coil and a secondary coil, a resonant frequency of the secondary coil side is arranged to become higher than a frequency of an oscillation signal of the primary coil side, so that a capacitance can be made small and the coupling coefficient of the primary coil and the secondary coil can be made high apparently and thus, efficiency of power transmission from the primary coil side to the secondary coil side can be improved.
