▎ 摘　　要

NOVELTY - Power management system comprises a first interface communicatively coupled to an electricity grid associated with premises, a second interface coupled to a graphene battery, hardware processors, and a non-transitory memory storing instructions. The hardware processors provide power to appliances within the premises under a first operation mode, detect an abnormal event associated with the electricity grid, and configure the system to provide the power to the appliances under a second operation mode in response to the detection. The first and second operation modes specify the electricity and the graphene battery as a sole power source. USE - The system is useful for providing power to appliances e.g. ventilators, heating systems, and other medically-necessary devices, in homes. ADVANTAGE - The system: enables utilizing a cloud computing model for providing service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service; and allows a cloud consumer to unilaterally provision computing capabilities, e.g. server time and network storage, as needed automatically without requiring human interaction with the service's provider, so that the capabilities can be automatically and quickly scale out and rapidly released to quickly scale in. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a supercapacitor (100). DESCRIPTION OF DRAWING(S) - The figure shows an exploded view of the supercapacitor. 100Supercapacitor 102External layer 106Graphene battery sheet 110Separator layer
