To do. Thereby, the power supply from all the battery devices connected to the electronic device 100 is stopped. In this case, since the user does not acknowledge that the non-regular battery device is connected to the electronic device 100, the second battery device 92 is a regular battery device but cannot be used.

  The process performed in step S180 shown in FIG. 4 is the same as the process performed in step S180 shown in FIG.

  In step S181, the user operates the operation unit 70, and the system control unit 50 determines whether the user has selected the YES icon. If the user selects the YES icon, the process proceeds to step S182. Otherwise, the process proceeds to step S192.

  The process performed in step S182 shown in FIG. 4 is the same as the process performed in step S182 shown in FIG.

  In step S192, the system control unit 50 displays information corresponding to “power supply is stopped” on the display unit 28.

  In step S193, the system control unit 50 operates the selection unit 85 with the power supply control unit 80, and disconnects all the positive terminals (+) of the first battery device 91 and the second battery device 92 from the power supply control unit 80. To do. Thereby, the power supply from the battery device is stopped. In this case, since the user does not acknowledge that the non-regular battery device is connected to the electronic device 100, the first battery device 91 is a regular battery device but cannot be used.

  Thus, in Embodiment 2, when the electronic device 100 and a plurality of battery devices are connected and the battery authentication process fails, whether or not the plurality of battery devices connected to the electronic device 100 are genuine products. Notify the user of information for inquiring the user. And it can be selected according to the answer from a user whether only the regular battery apparatus is selected as the battery apparatus which the electronic device 100 uses. Thus, in the second embodiment, when a plurality of battery devices connected to the electronic device 100 include genuine products and non-genuine products, the battery device used by the electronic device 100 is determined according to the answer from the user. Can be selected.
