Battery and authentication requesting device
View Patent ↗An authentication requesting device which includes a battery connecting section to be connected to a battery and a receiving section to be supplied with power from an external power source when connected to the external power source, and executes an authentication process for authenticating a battery connected to the battery connecting section, where the authentication requesting device is arranged to change the authentication process depending on whether or not the receiving section is being supplied with power from the external power source.
1. An authentication requesting device which comprises a battery connecting section to be connected to a battery and a receiving section to be supplied with power from an external power source when connected to the external power source, the authentication requesting device executes an authentication process for authenticating the battery connected to the battery connecting section, wherein:
the authentication requesting device is arranged to change the authentication process depending on whether or not the receiving section is being supplied with power from the external power source such that,
the authentication process is executed repeatedly in accordance with a repetition period; and
the repetition period of the authentication process is changed depending on whether or not the receiving section is being supplied with power from the external power source.
2. The authentication requesting device according to claim 1 , in which:
the authentication process is executed a plurality of times; and
a number of times that the authentication process is executed is changed depending on whether or not the receiving section is being supplied with power from the external power source.
3. The authentication requesting device according to claim 2 , wherein a failure process for powering off the authentication requesting device is executed if the authentication process has failed to authenticate the battery at any of the plurality of times at which the authentication process was executed.
4. The authentication requesting device according to claim 1 , wherein a failure process for powering off the authentication requesting device is executed if the authentication process fails to authenticate the battery.
5. An authentication system comprising:
a battery; and
an authentication requesting device according to claim 1 ;
the battery being connectable to the battery connecting section of the authentication requesting device.
6. A control method of an authentication requesting device for causing the authentication requesting device to execute an authentication process for judging whether or not a battery connected to a battery connecting section is genuine, the authentication requesting device comprising the battery connecting section to be connected to the battery and a receiving section to be supplied with power from an external power source when connected to the external power source, the method comprising the step of:
changing the authentication process in dependence on whether or not the receiving section is being supplied with power from the external power source, such that,
the authentication process is executed repeatedly in accordance with a repetition period; and
the repetition period of the authentication process is changed depending on whether or not the receiving section is being supplied with power from the external power source.
