Specific sockets and high-power connector cables have been developed to allow a simple and secure usage of boost charging stations. It is necessary for the end user to know which options are supported by a charging station. EVs may have an “identity” for electronic readout, e.g. by means of a certificate. Also, other information which can be communicated by an EV to the infrastructure may be relevant for the execution and planning of charging orders. The current battery charge condition, the power requirements during the charging procedure, as well as the cruising range are parameters that may be relevant for the planning of charging orders. The vehicle and charging station can communicate using a connector cable, but also other mechanisms are possible, e.g. using the back-end system of an EV manufacturer, to which an EV is connected (using mobile data connection).

roadway
definition

part of the surface of the road reservation primarily designed for the movement of vehicles that conform to a specified set of requirements

NOTE 1 to entry A roadway is characterized using a cross-section3.1.1) of a road facility as the roadway characteristics often change along the length of the road. See “road”, “road section”3.5.7), “road segment”, and “road link” for different types of stretches of roadway.

NOTE 2 to entry In practice, the roadway design considers a variety of issues, which can result in suboptimal road segments that violate normal design guidelines. Such locations are typically posted with warning signs, but they are still designed for the movement of vehicles.

NOTE 3 to entry While the roadway is designed with certain vehicle characteristics in mind, local regulations typically allow a wider set of vehicles to use the roadway.
