The server executes a process that includes receiving predetermined information from each terminal in a facility, if it is determined that the electric vehicle is connected to a charging/discharging station, associating a user or a user terminal with the charging/discharging station, scheduling a power demand and supply adjustment, receiving behavior information of the user, if it is determined that it is necessary to reschedule the power demand and supply adjustment, predicting a connection period, rescheduling the power demand and supply adjustment, and if the current time has reached the start time of a power supply and supply adjustment period, executing the power demand and supply adjustment.

A load management system for a hydroelectric power plant, includes a power generator configured to generate electrical energy from a flow of water for supplying a power grid, a virtual reservoir configured to store the generated electrical energy and dispatch the stored electrical energy to the power grid; a plurality of circuit breakers that connect an output of the power generator to the power grid and to the virtual reservoir; and a control unit configured to control operating states of the plurality of circuit breakers so that the generated electrical energy is stored at the virtual reservoir and at least one of the generated electrical energy or the stored electrical energy is provided to the power grid.

Embodiments of the inventive concept measure the amount of electrical power being consumed in one or more houses or buildings, before the utility meter or meters. These measurements are used by a smart load manager (SLM) apparatus, in addition to information about the maximum capacity of the electrical lines that are being measured, to maximize the number of electric vehicle supply equipment (EVSE) units that can be installed in the one or more buildings, and maximize the amount of power that is available for electric vehicle (EV) charging at any given time.

Systems and methods for monitoring and/or protecting state-of-charge of one or more batteries. One method comprises determining, via a controller, location information associated with the battery. The method includes determining, via the controller, one or more battery parameters. The method includes calculating, based on the one or more battery parameters and the location information, a state of charge of the battery. The method includes controlling, via the controller and based on the state of charge, a mode of the battery.

Electric vehicle charging management methods and systems are provided. First, a server receives a candidate charging request respectively from each of candidate charging stations or candidate mobile devices via a network. According to the candidate charging requests, at least one first charging station is selected from the candidate charging stations, and the first charging station is instructed to perform a first charging operation with an upper power limit value. The server sets the candidate charging requests of the candidate charging stations other than that of the first charging station to a pending state. When the first charging status information corresponding to the first charging operation meets an energy management condition, the server selects at least one second charging station from the candidate charging stations according to the candidate charging requests, and instructs the second charging station to perform a second charging operation with the upper power limit value.

Present invention concerns charging of a power source of a device. A power usage pattern collector is configured to: collect data on power usage in a device, power source of which is chargeable, with regard to at least one particular criterion having influence on power usage in the device; and determine at least one power usage pattern by use of the collected data, said power usage pattern specifying power usage in the device with regard to at least one particular reoccurring criterion. A charging controller is configured to: acquire at least one power usage pattern; and control charging of a power source of a device by use of the at least one acquired power usage pattern. Present invention relates also to corresponding methods, correspondingly arranged computer program products, correspondingly arranged computer-readable recording media, and a system comprising the power usage pattern collector and the charging controller.
