Abstract
An electric vehicle charging system and method of charging an electric vehicle are disclosed. The electric vehicle charging system is formed of a distributed system comprising a central control module housing communication, user authentication and metering devices and a local charging module housing at least two outlet connectors for connecting to an electric vehicle. The method of charging briefly comprises using a cyclical variation in charge between each of two vehicles connected to the local charging module.
Claims (12)
1. Method of charging at least two electric vehicles at a local charging module adapted to receive electricity from a local charging feed and to supply electricity to at least two electric vehicles, comprising: a) identifying the local charging module to an authentication system for electric vehi cle charging; b) receiving an authorisation signal in respect of the first vehicle at a central control ler in communication with a communications network and housed in a central control module adapted to receive electricity from a power distribution network and to distribute electricity to the local charging feed; c) receiving a signal at the local charging module that a first electric vehicle has been connected to a first charging outlet provided by the local charging module, the first charg ing outlet being coupled to the local charging feed by means of a local switching device d) in response to the authorisation signal, the central controller closing a central switch coupled to the local charging feed to cause electricity to flow between the central control module and the local charging module and closing the local switching device; e) initiating charging of the first electric vehicle; f) repeating steps a) to c) for a second electric vehicle at a second charging outlet provided by the local charging module; g) pausing the charging of the first electric vehicle to wait for a verification signal from the central controller that an authorisation signal has been received; and, the if veri fication signal is received, h) charging each of the first and second electric vehicle using charging cycles by switching electricity to the first and second charging outlets on and off by switching either the local switching device or the central switch to connect the local charging feed to ei ther the first or the second charging outlet for scheduled time periods to alternate paus ing charging and charging until at least one of the first or second electric vehicles has reached a desired electric charge.
2. Method as claimed in claim 1, wherein a charging feed is connected to each of the first and the second charging outlet, and a central charging switch coupled to each charg ing feed switches the electricity flow between the first and the second charging outlet.
3. Method as claimed in claim 1, wherein a single charging feed is connected to the first and the second charging outlet, and the local switching device switches the electricity flow between the first and the second charging outlet.
4. Method as claimed in claim 3, wherein the local charging module further compris es a local controller coupled to the local switching device and adapted to cause the local switching device to switch between the first and the second charging outlets.
5. Method as claimed in any of claims 2, 3 or 4, further comprising the steps of the local controller indicating to the central controller when charging switches between the first and second electric vehicle, and the local controller identifying to the central control ler when one of the first and the second electric vehicle ceases charging.
6. Method as claimed in claim 5, wherein the central controller is coupled to a single energy meter for the local charging feed, and wherein the indicating and identifying steps carried out by the local controller enable the central controller to determine the electrici ty used by each of the first and second electric vehicles.
7. Method as claimed in any preceding claim, wherein the verification signal is a volt age drop.
8. Method as claimed in any preceding claim, wherein the scheduled time periods are uniform.
9. Method as claimed in any of claims 1 to 8, wherein the scheduled time periods are non-uniform.
10. Method as claimed in any preceding claim, wherein the local charging feed carries a single-phase electricity supply.
11. Method as claimed in any of claims 1 to 10, wherein the local charging feed carries a three-phase electricity supply, and the first and the second electric vehicles are charged using different phases of the three-phase electricity supply.
12. Electric vehicle charging system comprising: a central control module adapted to receive electricity from a power distribution network and to distribute electricity to at least one local charging feed, comprising: at least one central switch, each central switch coupled exclusively to one of the at least one local charging feeds; and a central controller in communication with a communications network; wherein each central switch is adapted to be switched by the central controller on receipt of an authorisation signal transmitted to the central controller via the communications network; and at least one local charging module, remote from the central control module, and adapted to receive electricity from at least one of the local charging feeds and to supply electricity to an electric vehicle, comprising: a local switching device configured to be activated by the switching of the central switch coupled to one local charging feed; a at least two charging outlets adapted to connect to an electric vehicle coupled to the local switching device; and a local switch adapted to be switched by the local control ler and coupled to the outlet; wherein the local switching device is further adapted to switch the electricity sup plied to an electric vehicle between the at least two charging outlets.
