Method for controlling an exchange power between a charging infrastructure and an electricity supply grid
A method for controlling an exchange of power between a charging infrastructure and an electricity supply grid is provided. A number of power units are formed as electric vehicle. Each power unit has a variable state of charge. From the individual states of charge of the power units, an overall state of charge can be determined. For the overall state of charge, a flexibility range in dependence on time can be predefined for a control time period. The flexibility range is spanned by a progression over time of an upper limit of the overall state of charge and a progression over time of a lower limit of the overall state of charge for the control time period. The flexibility range has range points which can be defined by a value of the overall state of charge and a point in time in the control time period.

OPTIMIZED CHARGING OF ELECTRIC VEHICLES OVER DISTRIBUTION GRID
Techniques are presented for scheduling the charging of electric vehicles (EVs) that protect the resources of local low voltage distribution networks. From utilities, data on local low voltage distribution networks, such as the rating of a distribution transformer through which a group of EVs are supplied, is provided to a load manager application. Telematics information on vehicle usage is provided from the EVs, such as by way of the original equipment manufacturer. From these data, the load manager application determines schedules for charging the group of EVs through a shared low voltage distribution network so that the capabilities of the local low voltage distribution network are not exceeded while meeting the needs of the EV user. Charging schedules are then transmitted to the on-board control systems of the EVs for implementation.

ELECTRIC VEHICLE CHARGING SYSTEM
An electric vehicle (EV) charging system includes a number of output connections (e.g., cables). Each of the output connections is connected to at least one head, and each head can be connected concurrently to an EV. A controller can direct a charging current, delivered over a dedicated circuit from an electric power supply, to a first one of the output connections if a first EV is connected to a head connected to the first one of the output connections. Then, the charging current to the first one of the output connections can be stopped, switched to a second one of the output connections, and restarted if a second EV is connected to a head connected to the second one of the output connections.
