The method includes establishing a physical connection between the EV and the EVSE, initiating a payment authentication process, recognizing, by the EVSE, an EV identifier, entering an energy transfer stage and providing the price for charging on a display. A payment authentication state is defined for the payment authentication process. The payment authentication state includes at least an ongoing state and an approved state. The energy transfer stage is entered irrespective of whether the payment authentication state is the ongoing state or the approved state. The price for charging is provided on a display mounted to the housing of the EVSE.

Abstract: A charger system is disclosed. The charger system includes a stationary base including a base connector electrically connectible to an electrical supply line and a base guide. The charger system further includes a detachable charger top including a charger device, a top connector electrically connected to the charger device, and a top guide. When the charger top is mounted to the base, the top guide is configured to mate with the base guide such as to bring the top connector and the base connector into a predetermined positional relation to each other.

Abstract: The present disclosure concerns a method for charging or discharging an EV battery of an electrical vehicle (EV) using an electrical vehicle supply equipment (EVSE). The method comprises electrically coupling an EVSE charging interface conductor of the EVSE to an EV charging interface conductor of the EV. The method further comprises determining an EV present voltage provided by the EV battery at the inlet; and at least one of electrically charging or discharging the EV battery by the EVSE. The charging includes applying a charging voltage to the connector and limiting the charging voltage V by an upper voltage limit and wherein the discharging includes applying a charging voltage to the connector and limiting the charging voltage by a lower voltage limit. The upper voltage limit is determined as a function of the EV present voltage.

Abstract: A method of operating an electric vehicle supply equipment (EVSE), the method comprising receiving EVSE field data collected during a plurality of field charging processes of respective field vehicles by a field EVSE. The EVSE field data includes, for each of the field charging processes, respective current and voltage data representing time-dependent current and voltage applied for charging the field vehicle during the respective field charging process. The method further comprises identifying a vehicle type of the field vehicle based on the EVSE field data and configuring a vehicle charging profile for the identified vehicle type using the EVSE field data. The vehicle charging profile describes a charging behavior of the identified vehicle type, whereby parameters of a charge curve for the identified vehicle type are adjusted using the EVSE field data. The method further comprises operating the EVSE using the vehicle charging profile.
