Abstract

The charging of electric vehicles (121, 122) from a domestic electricity supply (117) is shown, in which a grid-connected source (117) supplies electricity to a plurality of dwellings (102, 103), with each dwelling having a charging outlet for charging an electric vehicle. A power management apparatus (201) is provided along with control units (211, 212). The power management apparatus establishes a weekly schedule (603, 604) for each dwelling, consisting of contiguous intervals (801) of less than one hour during which a respective control unit may permit the charging of an electric vehicle or is forced to inhibit the charging of the electric vehicle. The power management apparatus transmits respective schedule data, derived from an established weekly schedule, to each dwelling. Each control unit (211) is connected between the grid connected source (117) and a respective one of the charging outlets (1001). Each control unit receives the schedule data and stores this schedule data to re-establish a local copy of the weekly schedule for the respective dwelling, with any previously stored schedule being replaced. Thereafter, the control unit operates switches (1111, 1112, 1113) to permit the charging of an electric vehicle or inhibit the charging of the electric vehicle in accordance with the respective locally stored weekly schedule.

Claims (15)

1. A system for controlling the charging of electric vehicles from a domestic electricity supply, in which a grid-connected source supplies electricity to a plurality of dwellings and each said dwelling has a charging outlet for charging an electric vehicle, comprising: a power management apparatus; and a plurality of control units, characterized in that: said power management apparatus is configured to: establish a schedule for each said dwelling, consisting of contiguous intervals of less than one hour during which a respective control unit may permit the charging of an electric vehicle or is forced to inhibit the charging of an electric vehicle; and transmit respective schedule data, derived from a said established schedule, to each said dwelling; and each said control unit is connected between said grid-connected source a respective charging outlet; each said control unit is configured to: receive said schedule data; store said schedule data, wherein any previously stored schedule data is replaced; and operate switches to permit the charging of an electric vehicle or inhibit the charging of an electric vehicle in accordance with the respective locally stored schedule data.
2. The system of claim 1, characterized in that said power management apparatus includes a graphical user interface for receiving said schedules.
3. The system of claim 1, characterized in that said switches are implemented as cascaded relay devices.
4. The system of claim 1, characterized in that each control unit includes an additional storage device for recoding historical data relating to the operation of the respective control unit.
5. The system of claim 4, wherein each control unit includes a radio transmitter/receiver for receiving schedule data and transmitting said historical data.
6. A method of controlling the charging of electric vehicles from a domestic electricity supply, in which a grid-connected source supplies electricity to a plurality of dwellings and each said dwelling has a charging outlet for charging an electric vehicle, characterized by the steps of: establishing a schedule for each dwelling at a power management apparatus, wherein said schedules comprise contiguous intervals of less than one hour; producing schedule data for each said dwelling; transmitting said schedule data from the power management apparatus to respective control units, wherein each said control unit is connected between the grid-connected source and a respective one of said charging outlets; receiving transmitted schedule data at each control unit; storing received schedule data at each control unit, wherein any previously received schedule data is replaced; and operating each control unit in accordance with its stored schedule data to permit the charging of an electric vehicle or to inhibit the charging of an electric vehicle.
7. The method of claim 6, characterized in that said contiguous intervals are of a substantially similar duration.
8. The method of claim 7, characterized in that said contiguous intervals have a duration of between five minutes and thirty minutes.
9. The method of claim 8, characterized in that the schedule is interrogated during each said interval to determine whether charging is to be permitted or inhibited.
10. The method of claim 6, characterized in that: said schedule data defines a weekly schedule; and said operating step continues to repeat said stored weekly schedule.
11. The method of claim 6, characterized by storing data identifying when a control unit has been operated to permit charging.
12. The method of claim 6, characterized by the steps of: producing a command to inhibit charging in response to reading the local schedule data; calculating a random delay interval; and waiting for said random delay interval before de-activating the control unit to inhibit the charging of an electric vehicle.
13. The method of claim 6, characterized in that said step of establishing a schedule comprises the steps of: agreeing a contractual relationship with a customer for the provision of electricity for charging an electric vehicle; and recording the schedule via a graphical user interface.
14. The method of claim 13, characterized in that said step of establishing a schedule further comprises the steps of: establishing a weekly schedule; and 21 modifying said weekly schedule in response to anticipated events expected to increase electricity demand.
15. The method of claim 6, characterized in that said step of establishing a schedule comprises the step of establishing a modified schedule in response to an unexpected reduction in available electricity.
