The at least one processor may be configured to, upon receiving a user input information including a charging objective, derive a plurality of optimal charge maps that satisfy the charging objective based on battery state information and charger state information; output information on each of the derived optimal charge maps through a predefined graphical user interface (GUI); and upon receiving a user selection signal for one of the optimal charge maps, control charging of the battery based on an optimal charge map corresponding to the user selection signal.

An external battery device includes a battery, an input terminal that receives external power from a charger connected through a universal serial bus (USB) cable, a charging unit that charges the battery, and a processor configured to measure a voltage value of a first data terminal of the input terminal, set a charging current based on the voltage value of the first data terminal, and control the charging unit to charge the battery with the charging current that is set.

Disclosed is a method of communicating between an electric vehicle, a supply equipment, and a power grid, which is performed by an electric vehicle communication controller of the electric vehicle, the method including an operation of transmitting a discharge schedule including the amount of energy discharge, a discharge start time, and a discharge finish time to a supply equipment communication controller of the supply equipment or a power grid communication controller of a power grid operation server, receiving a discharge cost calculated according to the discharge schedule from the supply equipment communication controller or the power grid communication controller, and transmitting an authorization message for the discharge cost to the supply equipment communication controller or the power grid communication controller.

A parked vehicle charging method includes inputting vehicle information of a vehicle that is parked, parking space information, charging information requested by the vehicle, and necessary time information preliminarily secured by the vehicle to a management server, scheduling, by the management server, charging of the vehicle based on the requested charging information and the necessary time information of the vehicle, controlling, by the management server, charging intensity of charging equipment based on the vehicle information of the vehicle, the parking space information, and a charging schedule, and receiving, by the management server, charging result information from the charging equipment after charging end of the vehicle and calculating an amount of money to be charged to a user of the vehicle.

A method of operating a wearable monitoring system in which a tablet or smartphone-sized device directly charges a wristband without separate cords or swappable batteries. The method includes prompting docking based on a low wristband battery or a scheduled charging window, maintaining the tablet's full usability while docked, and charging via inductive power transfer (without exposed contacts) or via conductive interfaces (pins or surface pads). Retention may be magnetic, mechanical, or combinations thereof. The method improves charging compliance, ingress protection, tamper resistance and safety.

The present disclosure relates to systems, methods, and devices for controlling charging of vehicles, to avoid charging during charge-adverse time periods or during charge restriction events. This can advantageously reduce cost to vehicles owners, and or provide access to reward incentives. Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.
