Abstract
Claims
Demands
1. Charging installation (12) for electric vehicles, the charging installation (12) comprising: - a first number of charging points (20), the first number being greater than or equal to 1, - a second number of charging interfaces (24), the second number being greater than or equal to 2, each charging interface (24) having a connector adapted to be connected to an electric vehicle to enable the charging of the electric vehicle, the second number being strictly greater than the first number, - a multiplexer (26) suitable for connecting the charging interfaces (24) to at least one charging point (20), and - a computer (28), the computer (28) being suitable for receiving instructions to charge an electric vehicle by an external control system (14) and for controlling the multiplexer (26) and at least one charging point (20) according to the instructions of the external control system (14).
2. Charging installation according to claim 1, wherein the computer (28) is adapted to communicate with the external control system (14) and at least one charging point (20) by an OCPP protocol.
3. Charging installation according to claim 1 or 2, wherein the charging instructions of the external control system (14) include control instructions for a second number of charging points (20), the computer (28) being adapted to convert the control instructions of the external control system (14) into control instructions for each charging point (20).
4. Charging installation according to any one of claims 1 to 3, wherein the computer (28) is adapted to convert information from the charging points (20) into information from a second number of charging points (20) and to send the converted information to the external control system (14).
5. A charging installation according to any one of claims 1 to 4, wherein the multiplexer (26) is adapted to switch at least one charging point (20) from one charging interface (24) to another charging interface (24) upon receipt of a switch command, the computer (28) being suitable for determining a switching strategy comprising all the switching orders of the multiplexer (26) and the load points (20) from the orders received from the external control system (14).
6. Charging installation according to claim 5, wherein the computer (28) is suitable for optimizing the switching strategy so that at least one constraint is met.
7. Charging installation according to claim 6, wherein a constraint is that the total power consumed by the charging installation (12) remains less than or equal to a predefined power.
8. Charging installation according to any one of claims 5 to 7, wherein the computer (28) is suitable for optimizing the switching strategy so that at least one objective is achieved.
9. Charging installation according to claim 8, wherein an objective is to maximize the power used by the charging installation (12).
10. Charging installation according to claim 8 or 9, wherein one objective is an objective dependent on at least one user of the electric vehicle to be charged.
11. Charging installation according to any one of claims 5 to 10 wherein each charging interface (24) is suitable for operating in a single-phase charging mode and in a three-phase charging mode, the switching strategy also determining switching orders between the charging modes.
12. Research installation according to claim 11, wherein, in single-phase charging mode, the computer (28) is also suitable for selecting a phase from among the available phases to carry out the charging.
13. Charging installation according to any one of claims 1 to 12, wherein each charging interface (24) includes at least one connector and one operating indicator.
14. Charging installation according to any one of claims 1 to 13, wherein the charging installation (12) further comprises a user interface (18), the computer (28) being adapted to transmit information obtained by the user interface (18) to the external control system (14).
15. Charging station (10) for electric vehicles, the charging station (10) comprising: - an external control system (14), and - a charging installation (12) according to any one of claims 1 to 14.
