Abstract
A power supply device including: (a) a power supply unit group composed of a plurality of power supply units and connected with a power consuming appliance; and (b) a control device configured to control the power supply unit group, wherein the control device and each of the power supply units are connected to each other by a communicating circuit.
Claims18
A power supply device comprising:
- (a) a power supply unit group composed of a plurality of power supply units and connected with a power consuming appliance;
- and
- (b) a control device configured to control the power supply unit group, wherein
- the control device and each of the power supply units are connected to each other by a communicating circuit,
- when a power supply unit is removed from the power supply unit group, the control device updates a cryptographic key shared to perform communication between the control device and each of the power supply units, and
- when the power supply unit is returned to the power supply unit group, the control device checks whether the power supply unit in question is the power supply unit removed from the power supply unit group, and when the power supply unit in question is the power supply unit removed from the power supply unit group, the control device sends the cryptographic key to the power supply unit in question.
