The invention relates to means for a calibration standards-compliant determination of the electrical energy transferred from a charging station, which make a measurement at the transfer point, that is to say at the vehicle-side end of the charging cable, unnecessary. Here, the electrical energy transferred from a charging station is determined by a measurement of the energy before the transfer point, wherein the reactive power component from the termination point as far as the transfer point is compensated. The reactive power component is determined from at least one second electrical variable, for example a resistance of a conductor or a conductor shield, which is in a fixed relationship with an analog electrical variable that is relevant to the transferred electrical energy, for example an ohmic total resistance of at least two conductors involved in a charging circuit.

This specification describes an electrically powered modular platform comprising a power module comprising a common power bus, the power module electrically connected to a power source; one or more service modules that provide a service; a termination module that is configured to cover an opening in the one or more service modules, wherein the power module, each of the one or more service modules, and the termination module are modular and stackable, and wherein the power module and each of the one or more service modules are electrically connected using the common power bus to provide power to each of the one or more service modules.

A direct current (DC) electric vehicle supply equipment (EVSE) that includes a secure enclosure. The secure enclosure encloses a set of one or more contactors to open and close to provide DC charge transfer with one or more electric vehicles; a conductor to electrically connect the contactors with DC input; a current sensor to measure current draw; a voltage sensing circuitry to measure voltage; and one or more circuits that receive current data from the current sensor and voltage data from the voltage sensing circuitry, the one or more circuits to perform one or more safety functions and one or more metering functions using the received current data and voltage data. The DC EVSE may also include, external to the secure enclosure, a controller that is coupled with the circuits to control the opening and closing of the set of contactors.

Method for managing charging service comprising independent Installers, independent utilities, independent electric charging customers, CO2 levels, and independent energy markets, the method comprising: electronically calculating cost of service on a periodic basis based on a plurality of dynamically changing influencing parameters; electronically determining a capital cost of installation; obtaining customer's zip code to determine regional variations in installation cost; estimating customer's location from customer's IP address to determine regional variations in installation cost; Soliciting information about conditions at an installation location which may affect installation cost by soliciting customer input in response to an online questionnaire; soliciting an address of the installation location, then obtaining data comprising age of a building, size of the building and number of units from publicly available data bases, to determine installation cost.

An in-store customer transaction can be detected. Power charging credits can be assigned to the customer based, at least in part, on the in-store customer transaction. A charging station can be activated for the customer. Whether an amount of energy consumption by at least one user device of the customer from the charging station has reached a threshold value can be determined. The threshold value can be based, at least in part, on the charging credits assigned to the customer. Responsive to determining that the energy consumption by the at least one user device of the customer from the charging station has reached the threshold value, the charging station can cease or reduce power being delivered by the charging station to the at least one user device of the user.

A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU. The reservation is for a user account that has requested a desire to charge the battery of the electric vehicle of the user at the CU or another CU. The method includes sending, by the server, a confirmation for the reservation to the user account. The confirmation is viewable via a device having access to the server via the user account. The method includes sending, by the server, a data regarding a time of availability of the CU to the user account for the reservation. The computer of the CU is configured to display a visual indicator regarding the reservation of the CU.

An in-store customer transaction can be detected. Power charging credits can be assigned to the customer based, at least in part, on the in-store customer transaction. A charging station can be activated for the customer. Whether an amount of energy consumption by at least one user device of the customer from the charging station has reached a threshold value can be determined. The threshold value can be based, at least in part, on the charging credits assigned to the customer. Responsive to determining that the energy consumption by the at least one user device of the customer from the charging station has reached the threshold value, the charging station can cease or reduce power being delivered by the charging station to the at least one user device of the user.

Embodiments described herein provide a client system for facilitating enhanced offline payment. During operation, the system obtains a location indicator, which indicates the location of a service, from a charging system. The system then generates an offline code that allows access to the service and corresponds to the location indicator. The offline code can be readable by the charging system, and the client system and the charging system can both be offline. Subsequently, the system encodes the historical data associated with the service in a field of the offline code and sends a message comprising the offline code to the charging system.

The disclosure relates to a method for exchanging electrical energy between an energy-storage unit in a vehicle, operated by a vehicle operator, and an energy-user. The energy-storage unit has been configured to store electrical energy long-term. An electrical connection between the energy-storage unit and the energy-user can be configured to exchange energy. In accordance with the disclosure, there is provision that an exchange of energy from the energy-user into the energy-storage unit of the vehicle in a first energy-transmission direction, or from the energy-storage unit of the vehicle to the energy-user in a second energy-transmission direction, takes place, in order to provide an energy service by the vehicle operator. The exchange of energy takes place as a function of an energy price, set by the vehicle operator, for the energy service. The energy price is ascertained as a function of a storage-unit status of the at least one energy-storage unit.

A controller may, after receiving indication that an electric utility provider will reduce power supplied during an upcoming period of time, increase a cost of charge energy for vehicles that charge at a rate at least equal to a threshold rate during the upcoming period of time. The controller may also decrease the cost of charge energy for vehicles that avoid charging or charge at a rate less than the threshold rate during the upcoming period of time.
