Abstract
Aspects of the present disclosure relate to managing power provided to devices. A first set of radio-frequency identification (RFID) power data can be read, by an RFID reader, from a first RFID tag of a first device electrically coupled to a power supply. The first set of RFID power data can specify a first amount of energy required by the first device if a power loss occurs. An indication that a power loss occurred can be received. In response to the indication that the power loss occurred, the power supply can provide the first amount of energy to the first device.
Claims14
A method comprising:
- reading, by a radio-frequency identification (RFID) reader, a first set of RFID power data from a first RFID tag of a first device electrically coupled to a power supply, the first set of RFID power data specifying a first amount of energy required by the first device if a power loss occurs;
- reading, by the RFID reader, a second set of RFID power data from a second RFID tag of a second device electrically coupled to the power supply, the second set of RFID power data specifying that the second device does not require power if a power loss occurs;
- receiving an indication that the power loss occurred;
- providing, by the power supply, in response to the indication that the power loss occurred, the first amount of energy to the first device;
- and
- disabling, in response to the indication that the power loss occurred, a socket the second device is electrically coupled to.
A system comprising:
- a first device having a first radio-frequency identification (RFID) tag;
- a second device having a second RFID tag
- a third device having a third RFID tag;
- and
- a power distributor electrically coupled to the first second, and third devices, the power distributor having a memory, an RFID reader, and a processor, the power distributor configured to perform a method comprising:
- reading, by the RFID reader, the first RFID tag of the first device;
- determining, based on reading the first RFID tag, a first power draw of the first device;
- reading, by the RFID reader, the second RFID tag of the second device;
- determining, based on reading the second RFID tag, a second power draw of the second device;
- reading, by the RFID reader, the third RFID tag of the third device;
- determining, based on reading the third RFID tag, a third power draw of the third device;
- determining, that an addition of the first power draw second power, and third power draw exceed a power limit of the power distributor;
- and
- providing power to the first and second devices and not the third device based on the first and second devices being higher priority than the third device.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
- determining, by instructing a radio-frequency identification (RFID) reader to read a first RFID tag of a first device, a first voltage requirement of the first device;
- determining a second voltage requirement of a power distributor;
- determining that the first voltage requirement and second voltage requirement are different;
- and
- not providing, in response to the determination that the first voltage requirement and second voltage requirement are different, power to the first device electrically coupled to the power distributor, wherein power is not provided to the first device by disabling, via a switch, a socket the first device is electrically coupled to on the power distributor.
