Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. A power source device comprising:
a first interface to receive, when the first interface is electrically coupled to a power supply, power from the power supply;
a second interface to output, when the second interface is electrically coupled to a power sink device, power contracts to the power sink device;
a power measurement controller to measure, when the second interface outputs a previous one of the power contracts, a total amount of the power consumed by a system comprised of the power sink device and the power source device; and
a power contract manager to ascertain, when the power contract manager determines whether or not the total amount exceeds a power supply rating of the power source device, a power value for a subsequent one of the power contracts,
wherein the power value for the subsequent one of the power contracts, when the power contract manager determines that the total amount exceeds the power supply rating, is lower than a power value for the previous one of the power contracts.
