  • the CLO can typically enter an agreement with one of a number of different ESP's, whereas the DSO is tied to the location of the CLO.

  • such roaming permits the EV owner to be provided with one bill for all the EV costs. This requires that all consumption is registered with all required information for billing.
  • the CLO may be resolved.
  • the energy bill may consist of two parts, energy and distribution costs. Both costs are handled by the grid owner as the energy, in kWh, is reduced from the measured energy i.e. no money is involved when it reports to the ESP.

  • Mobile unit 1 10 such as an Electrical vehicle (EV): e.g. any fully or partially electric vehicle able to communicate using the interfaces described by the electric vehicle charge service provider.
  • the vehicle may be a plug-in hybrid electric vehicle (PHEV) or a plug-in hybrid vehicle (PHV).
  • the mobile unit may also be a general purpose short term energy consumer such as a construction equipment.
  • a Connected Vehicle Platform (CVP) is utilized.

  • HMI human interface
  • GUI graphical user interface
  • the CVP is able to directly com- municate errors to the user via SMS or similar means of communication.
  • Electric vehicle or mobile unit charge or consumption subsystem (EVCS) 101 : This subsystem generates charge or transfer schedules from the information retrieved from vehicle, as well as from the grid operator and energy supplier. The main aim of this subsystem is to optimize energy consumption of the EV or mobile unit with respect to the users expected or wanted time of using the EV and other desires of the EV owner such as the cost of consumption, and primary energy source (wind, hydro, nuclear etc.). For instance, the EVCS may be connected to an energy supply bourse which provides day- ahead information of the market price on energy on a regional basis. This system also records information used by energy supplier and/or grid operator for billing purposes. It will also ensure that information about the future load situations is provided to grid operator and energy suppliers. Charge schedules are initiated once vehicles are connected to the electricity grid and may be updated whenever the input data changes. This service also enables user interaction (with regards to consumption) using web or phone applica- tion.
  • EVS Energy transfer validation subsystem 102: Based on grid properties, current and predicted load situations, the grid operator, e.g. DSO, verifies that the charge schedule will not lead to grid congestion. Rescheduling is performed if stability is in dan- ger.
  • the ETVS couples to a geographical Information System, GIS, that manages data of all consumption locations including meter position, owner and address.
  • EVCS is primarily used for managing battery charging and climatization processes for electrical vehicles. EVCS may be used as a key component for demand response im- plementation towards smart grid, multiple meter reading and for pre-paid electricity, and general purpose short term energy consumers such as construction equipment etc.
  • the EVCS can be deployed as an application server (AS) in an IMS (I P Multimedia Sub- system)-based service environment, but it can also run independently of IMS.
  • AS application server
  • IMS I P Multimedia Sub- system
  • EVCS may communicate with the various actors shown in fig.1 , and optimizes and manages remotely the energy consumption based on input from the driver, grid operators, energy providers and vehicle characteristics. The optimization can be done on a cost perspective, sustainability perspective (i.e. , C02 emission and type of energy), by time (charge as fast as possible, charge now) or when the energy grid has the lowest load.
  • sustainability perspective i.e. , C02 emission and type of energy
  • time charge as fast as possible, charge now
  • One of the main purposes with EVCS is enabling large scale usage of electrical vehicles e.g., connect multiple actors such as grid operators, energy suppliers and car manufactures. In fig.
  • the EVCS subsystem 101 is implemented in EVCS unit 101 , comprising a scheduler, SCH, a charging information aggregator, CH_AG, a history storage, HIST, a policy enforcement unit, POL_ENF, a business service unit, BUS_SERV, equipment control, EQ_CTRL, and an application programming interface element, APM .
  • the main component within the Electrical Vehicle Charge System is the scheduler, SCH. It produces individual charge or transfer schedules for each individual car connected to the service.
  • the schedule defines when and how the batteries shall be charged. It is based on input from:
  • a grid profile including an expected network (DSO) and / or supply (ESP) load profile for the coming 24 hours based on load statistics, prices, type of energy, subscrip- tion data etc.;
  • a user preferences profile estimated time of departure, distance, convenience range, optimization preferences (cost, C02, time i.e., charge as fast as possible);
  • Car / battery the charging logic in the car calculates an initial battery charging request, based on various battery status information as current energy level, age, capac- ity, temperature, maximum charging current, climatization pre-conditioning of batteries / passenger compartment, engine pre-heating etc.
  • DSO aging related to congestion
  • a charge schedule is negotiated. Since the grid is expected to become congested during early evening, the transmission cost for this period is rendered expensive in an effort to locally "shape" the load. Despite the enhanced price, some vehicles owners may want to charge their vehicles during this period. Eventually, the load becomes so high that the power grid's stability is threatened.
  • the grid operator instead of shutting down the entire section of the grid, the grid operator asks the scheduler to reschedule the charging for the EVs in the congested area.
  • the scheduler asks the EVs for their profiles for energy need, electricity cost as well as their chosen optimization profile.
