FIG. 1 shows a configuration diagram of a system device which can be driven by a secondary battery and to which N secondary batteries are connected. The system device shown in FIG. 1 includes an AC adapter 5 to which the system device 1 and an outlet 6 are connected.
Consists of The system device 1 is composed of a system control circuit unit 2 for controlling the system, a battery control circuit unit 3 for controlling N secondary batteries, and a DC / DC converter 4. The battery control circuit unit 3 and the N secondary batteries are N
They are connected by individual connecting portions 8, 9, 10, 11 and secondary batteries 12, 13, 14, 15 are connected to the respective connecting portions, respectively. The secondary battery select signal 7 is a signal output from the system control circuit unit 2 to the battery control circuit unit 3. Here, in the connection part to which the secondary battery is connected,
ID number 1, ID number 2, ... ID number N
And one ID number is assigned to one connection part. By assigning each ID number to the connection section, the batteries appear to have different ID numbers from the system control circuit section 2 and the battery control circuit section 3. N by using ID number
It is possible to discriminate the individual secondary batteries, and it is possible to control each secondary battery independently. Further, by providing the connection part with the ID number, it is not necessary for the battery itself to have information such as a self-identification number, and it is possible to control even a secondary battery that does not have such information.

が出来る。By constantly checking the remaining amount of each battery by using each ID number of the secondary battery, the system device can be driven by the minimum necessary secondary battery according to the operating condition of the system device. You can When the system control circuit unit 2 selects the required number of secondary batteries, the secondary battery select signal 7 is made effective to inform the battery control circuit unit 3 which secondary battery is to be enabled. The battery control circuit unit 3 detects the secondary battery select signal 7 output from the system control circuit unit, recognizes the selected secondary battery, and enables the battery. Therefore, when a peripheral device etc. is connected to the system unit and the required current capacity becomes large and it cannot be driven by one secondary battery, all secondary batteries are selected and enabled. As a result, a sufficient current capacity can be supplied from the secondary battery. Further, when the power consumption is low, it is possible to prevent wasteful consumption of other secondary batteries by enabling only one secondary battery. Further, even if there is a case where it is desired to preferentially consume any one of the N secondary batteries, the remaining amount can be preferentially consumed by selecting and enabling only that battery. It is possible to effectively utilize N secondary batteries.
