Abstract: A coordinated multiple power management system provides an efficient and unique means of controlling the power usage of devices attached to a personal energy platform. Power control in an abundant power situation (i.e. commercial power is available) saves money. Power control in a constrained power situation (i.e. commercial power is unavailable e.g. “power failure”) provides more availability of needed computing services (for example, emergency activities, enable longer communication periods, longer video streaming, security monitoring, internet access and communications, or critical healthcare device usage etc.). The power supplied to the devices can be determined automatically and is under program control, which allows the complete management and distribution of power to any, and all, devices attached to the personal energy platform.
