1. A charge-discharge control system in which a plurality of charge-discharge elements are configured to autonomously control charging-discharging, the charge-discharge control system comprising:
an external control device configured to broadcast a control signal to the charge-discharge elements that perform charging-discharging; and
an authentication device separate from the external control device and configured to permit charging-discharging of each of the charge-discharge elements, wherein
the charge-discharge elements are configured to, having received the control signal, transmit, to the authentication device, a permission request signal for requesting permission for charging-discharging, which is based on the received control signal,
the charge-discharge elements are not configured to perform mutual communication with the external control device and the authentication device,
the authentication device is configured to
having received the permission request signal, determine whether the permission request signal is a permission request signal based on the control signal received by the charge-discharge elements, and
connect a power line for performing charging-discharging to the charge-discharge elements upon determining that the permission request signal is the permission request signal based on the control signal received by the charge-discharge elements,
the authentication device is provided in plurality, and the external control device is configured to broadcast the control signal to the plurality of authentication devices and to the charge-discharge elements that perform charging-discharging,
the charge-discharge elements transmit, to the plurality of authentication devices, the received control signal, or a signal obtained by editing the received control signal, as the permission request signal, and
the plurality of authentication devices
receive the control signal and the permission request signal, and
upon determining that the permission request signal is the control signal received at the same time as the permission request signal or the signal obtained by editing the control signal, connect the power line for performing charging-discharging to the charge-discharge elements.
