Description

Description Title of the invention: Electric vehicle charging system comprising a network of interconnected electric charging sockets

[0001] The present invention relates generally to the field of electric vehicle charging and more particularly to an electric vehicle charging system comprising a network of connected electric charging sockets.

[0002] In the present invention, a network of connected electric charging points is defined as a set of similar charging points installed in parking facilities, particularly in the basements of buildings, which have the ability to communicate with each other and with remote servers.

[0003] Connectivity refers to the ability of a system, device, or network to connect to other systems, devices, or networks.

[0004] In the context of the present invention, connectivity refers to the ability of a charging station to ensure the autonomy of its access to a data communication network, in particular the Internet network.

[0005] The development of electric vehicles, whether cars, bicycles or motorized two-wheelers, is accompanied by a need for the deployment of a multifaceted electric charging infrastructure.

[0006] Thus, we find very high power charging systems on highways and transit areas, and medium power charging systems in stations, or on the roadside.

[0007] Low-power charging systems can also be found in everyday living and parking areas, particularly in public or private car parks, for example in the basements of buildings.

[0008] We will focus more particularly, but not exclusively, on this latter form of charging which tends to develop especially as economic realities and the constraints of the electricity distribution network argue in favor of a very large number of low power charging points.

[0009] We are familiar with large-scale charging power management and control solutions that employ significant resources in terms of hardware, software, and finances. These sophisticated management and control solutions are generally reserved for high-power charging stations or terminals, using direct current or three-phase alternating current.

[0010] Regarding low or medium power systems, we know of charging stations installed in parking infrastructure, particularly in the basement of buildings, using electrical outlets that can communicate with each other to locally manage the distribution of a limited available electrical power, to meet the charging needs of a vehicle connected to one of the outlets in the station and to calculate the cost of charging.

[0011] These systems do not allow for the effective resolution of connectivity problems: partial or total loss of connection with the Internet network in environments not conducive to the propagation of electromagnetic waves, particularly in the basements of buildings with fixed (walls, ...) and / or mobile (vehicles, ...) obstacles blocking or impacting the propagation of this type of wave.

[0012] Especially since wireless communications between outlets mainly use short-range wireless communication technologies such as Wifi, which are sensitive to electromagnetic interference and must be taken into account when installing outlets in the infrastructure.

[0013] To address these drawbacks, the present invention proposes a robust and flexible solution to optimize the connectivity of a network of connected sockets under difficult and / or changing connectivity conditions between sockets.

[0014] To this end, the invention has as its first object an electric vehicle charging system comprising a network of connected electric charging sockets in which each connected socket is able to communicate with a dedicated remote charging control server;each connected outlet in the park defining a node of a short-range wireless mesh communication network, in particular a Wifi mesh network, comprising a communication interface, capable of communicating with a communication interface of at least one other outlet in the park within radio range, called a neighboring outlet, and available to manage communication data traffic, and comprising a management and control module for the data traffic passing through the outlet, capable of indicating to its neighboring outlet its ability to access a data communication network, in particular the Internet network, either directly or via at least one of the outlets in the park via a communication path determined between outlets in the park;the traffic management and control module of a given socket when it is activated for charging, being further configured to be able to choose a specific path from among the communication paths indicated by the neighboring socket(s) available to connect to the dedicated remote server via the data communication network, according to specific selection criteria.

[0015] According to one characteristic, the communication interface of the socket having a capacity to access the data communication network, includes means of communication, capable of exchanging data with the data communication network, in particular the Internet network, chosen from at least means of communication with a mobile network, in particular LTE (“Long Term Evolution” in English), means of communication of type Bluetooth or Wifi, and means of wired connection of type PLC or Ethernet.

[0016] According to another characteristic, the ability of a socket to communicate with a neighboring socket depends on the load of the socket's management and control module and / or the electromagnetic conditions in the immediate environment of the socket.

[0017] According to another characteristic, the criteria for choosing the communication path are the quality of connectivity of the socket determined with its available neighboring sockets and the number of additional intermediate sockets needed relative to each of the available neighboring sockets to access the data communication network.

[0018] According to another characteristic, an additional selection criterion is the connection speed with the data communication network.

[0019] According to another characteristic, each charging control server is linked to a remote park monitoring server, capable of managing the charging control of all the sockets in the park of sockets, via the data communication network or another communication link.

[0020] The present invention has as its second object a socket intended for a bank of sockets of a charging system as described above, comprising a housing supporting an electrical current delivery module capable of being connected to an electrical current distribution panel to supply an electrical current to an electric vehicle connected to said socket via electrical connection terminals of the current delivery module;said box further supporting a control module coupled to the current delivery module, capable of controlling and managing the charging based on data exchanged between the current delivery module and a communication interface, coupled to the management and control module, supported by the box, comprising means of communication chosen from at least means of communication with a mobile network, in particular LTE, means of communication of the Bluetooth or Wifi type, and means of wired connection of the PLC or Ethernet type.;

[0021] According to one characteristic, the electrical current delivery module also includes measurement means capable of measuring the consumption of the current supplied by the socket during electrical charging, coupled with means of identifying the current consumer capable of allowing the association of a determined consumption with a consumer identified and authorized by a remote supervision server.

[0022] The present invention has as its third object a method implemented by the management and control module of each of the sockets in the network of connected sockets of the charging system as described above; said method comprising a first step in which each of the sockets indicates to its available neighboring sockets its ability to access a data communication network, in particular the Internet network, either directly or via at least one of the other sockets in the network defining a determined communication path between the sockets in the network, and a second step in which, when a socket is activated for charging, the activated socket chooses a determined path from among the communication paths defined by its available neighboring sockets to connect to a dedicated remote server via the data communication network,depending on the quality of connectivity of the activated socket with its available neighboring sockets and the number of additional intermediate sockets required relative to each of the available neighboring sockets to access the data communication network and, optionally, depending on the connection speed with the data communication network.

[0023] Finally, the present invention has as its fourth object a computer program product comprising instructions which, when the program is executed by a computer, lead the latter to implement the steps of the process as described above.

[0024] Other advantages and features of the present invention will become clearer from the following description, given solely by way of non-limiting example and with reference to the drawings in which:

[0025] [Fig.1] illustrates a block diagram of a connected socket from a network of connected sockets of a charging system according to the invention;

[0026] [Fig.2] illustrates a functional diagram of a charging system according to the invention with a first example of a connectivity situation between the sockets in the park;

[0027] [Fig. 3] illustrates the functional diagram of [Fig. 2] with a second example of a connectivity situation between the park's outlets; and

[0028] [Fig.4] illustrates, by means of a flowchart, the main steps of a process implemented in the system according to the invention.

[0029] The invention relates to a charging system comprising a network of connected electric charging sockets organized in the form of a proprietary self-reconfiguring mesh communication network, particularly utilizing Wifi technology, and in which each socket behaves as one of the nodes of the mesh network.

[0030] Each of the sockets includes a communication interface.

[0031] The communication interface of at least one of the outlets in the park includes means of communication allowing access to a data communication network and more particularly to the Internet network, via "long distance" wireless communication technologies such as ETE, 3G, 4G, 5G, ... This outlet thus defines an Internet access point.

[0032] Each outlet is constantly searching for the best communication path between itself and the other outlets in the park within the mesh network to access the Internet network access point.

[0033] In addition to wireless access methods (Wifi, LTE, etc.), there is the possibility of using a wired connection such as Ethernet or PLC.

[0034] The best communication path (or route) is the most promising path in terms of quality of service to the network access point to be able to send / receive data packets to or from a remote server without degradation of connectivity.

[0035] The choice of the best path takes into account the availability of the means of communication of the sockets at a given moment by adapting in real time to changes in the immediate environment of the sockets in the park (moving vehicles, disconnections, ...).

[0036] These paths change dynamically, so as to ensure that the best path is always used according to a number of parameters: environmental constraints (new parked cars block the propagation of waves), availability and processing capacity (congestion) of the connectivity management and control module of a socket, availability at the end of the chain (output) of the means of communication from the network access point, to a mobile telephone network (mobile network) using the LTE standard: 4G, 5G, ... (those that "lock onto" the mobile network) which will ensure the final connectivity with a remote server.

[0037] Because, ultimately, while data packets may take varying paths over time, they will always need a reliable Internet access point.

[0038] Preferably, communication methods using mobile phone network technology, particularly LTE, are used to communicate with the remote server via the internet network, but nothing excludes other means already present in the infrastructure (basement of building) in which the sockets are arranged, and in particular another wifi network or a wired connection, by power line communication (PLC) or Ethernet, forming a gateway to the internet network allowing access to the remote server.

[0039] Availability and connectivity require maintaining a balance between dynamic reassignment of communication paths and the stability of the connection of the sockets with the remote server, since the sockets must be able to be controlled remotely (and therefore reachable) at any time, in real time from the remote server.

[0040] Figure 1 illustrates, by means of functional blocks, a PCn connected socket belonging to a fleet of PPC connected sockets according to the invention, with "n" varying between a determined minimum number of sockets and a determined maximum number of sockets that can be managed in the same fleet.

[0041] In the following description, and for simplicity we will use the term "socket" to refer to the BTP box supporting BCE electrical connection terminals and the hardware and software components assembled in the BTP box, locally managing the metering and distribution of charging current to an electric vehicle and the hardware and software components participating in the management of the mesh network, described in detail below.

[0042] For example, there are three BCE electrical connection terminals in a standard low power Type E electrical outlet: two phase terminals and one earth terminal.

[0043] The PCn socket is capable of supplying direct or alternating current, single or three-phase. It is connected to an electrical power distribution network via a TDE electrical panel of an electrical infrastructure, for example already existing, of a building housing the PPC socket park, in particular a basement of a residential building, office building or other.

[0044] The BTP enclosure delimits a closed housing grouping the various hardware and software components assembled for example on one or more printed circuit boards, not shown.

[0045] The BTP box supports an MDC module for delivering electrical current, coupled to the TDE electrical panel.

[0046] The MDC current delivery module includes, from its input to its output, an internal DJI circuit breaker, ITC means for activating and deactivating the PC socket to respectively allow the supply or cessation of current supply (controlled switch) to an electrical consumer, in particular an electric vehicle, not shown, connected to the BCE terminals of the PC socket, current measurement means including a CDC current sensor coupled to MCE means for metering the electrical current consumed (meter) during charging, and the BCE electrical connection terminals capable of supplying current to the electric vehicle, via a plug and electrical connection cable connected to the electric vehicle, not shown.

[0047] Means of identifying the current consumer MID (QR Code or other) allowing the association of a determined consumption to a consumer identified and authorized by a remote supervision server SBO (Figures 2 and 3), are coupled to the current measurement means CDC, MCE.

[0048] The BTP box also supports an MGP module for managing and controlling the PCn socket for charging.

[0049] The MGP module manages data traffic passing through the PCn socket within the PPC socket network, organized as a Wi-Fi mesh network, in which the PCn socket acts as one of the network nodes. The BTP unit includes an ICR network communication interface coupled to the MGP module.

[0050] The ICR communication interface includes means (resources) of communication allowing at a minimum short-range wireless communication, including Wifi, with the other outlets (nodes) of the PPC network (mesh network).

[0051] The ICR communication interface of at least one of the PCn sockets in the PPC network also includes means of long-distance wireless communication, including LTE, or wired, with a remote OMn server for controlling the PCn socket (Figures 2 and 3); the same remote OMn server can manage several PCn sockets.

[0052] The MGP module is also coupled to the MDC power delivery module to control and manage the current delivered by the PCn socket.

[0053] The BTP box supports an MDM "mass" memory coupled with the MGP module. This MDM memory allows the PCn socket to locally store information not sent to the device and information necessary for its proper operation (socket state before a charging cycle restarts, latest charging data, etc.). This information storage enables charging to restart following an interruption, ensuring that if charging was in progress, it restarts directly from the state it was in at the time of the interruption. A timer is included to allow charging to restart automatically once a predetermined period, typically one minute without information exchange with the SOM server (Figures 2 and 3), has expired.

[0054] The MGP module is made from at least one processor or microcontroller. It plays the role of a conductor in the operation of the mesh network, which manages the data traffic (messages, requests, ...) exchanged between the different PCn sockets of the PPC socket park to find the best path to the exit point (network access point) and then communicate between the socket in question (activated socket) and the remote OMn server via the RCD Internet network (Figures 2 and 3).

[0055] It also acts as an intermediary for controlling the charging between the remote server OMn and the PCn socket when the best path has been found.

[0056] The data transmitted by the PCn socket to the remote OMn server (Figures 2 and 3) relates to information such as: "vehicle charging", "vehicle unplugged", "charging complete"; "electrical consumption", ...).

[0057] The data transmitted by the remote server OMn to the PCn port (Figures 2 and 3) relates to commands of the type: "start a reload session", "stop a reload session", "restore an interrupted reload session", "receive and apply an update", ...

[0058] The PCn socket's ICR network communication interface uses short-range wireless communication methods, including Wifi, capable of managing communication protocols and establishing communication between PCn sockets in the same PPC socket network, organized on the basis of a Wifi mesh network.

[0059] The ICR network communication interface of at least one of the PCn sockets in the PPC socket park also includes long-distance wireless communication means, including LTE, capable of managing communication protocols with remote OMn servers and in particular remote servers integrating interoperability logic, for example, via the standard OCPP protocol for "Open Charge Point Protocol" which allows monitoring the status of each PCn ​​socket in real time and controlling the PCn sockets for charging.

[0060] The number of PCn outlets (LTE outlets) with long-range wireless communication capabilities will be kept to an absolute minimum for cost reasons. The number of LTE outlets also depends on the layout of the locations where the outlet parks are installed.

[0061] A remote server, as defined in the present invention, can be an OMn control server for one or more outlets ("Outlet Manager") or an SBO supervision server ("Back Office") for all PCn outlets in the PPC network, dedicated in particular to a customer who owns the PPC network. This SBO server is responsible for supervising the PPC network, both with regard to managing charging and monetizing charging, in conjunction with the remote OMn servers, notably via the RCD Internet network, or through another LCR communication link (Figures 2 and 3); a single remote OMn server can also manage several PCn outlets.

[0062] The SBO monitoring server has a global view of all the sockets and controls the charging between the different sockets in the park according to several parameters (number of vehicles to be charged, number of vehicles being charged, duration of a charging session).

[0063] Figure [Fig.2] illustrates a functional diagram of a SYS charging system according to the invention, in a first PCn socket connectivity situation.

[0064] By convention, in the following description, the term "Wifi socket" will be used to designate a socket in the park whose means of communication only include "short range" wireless communication resources, notably Wifi, and the term "LTE socket" will be used to designate a Wifi socket which also has "long range" wireless communication resources, notably LTE.

[0065] To explain the operation of the Wifi mesh network, uniting the sockets of the same socket park, like nodes of a mesh network, we introduce the notion of "neighboring" nodes, or neighboring sockets.

[0066] This notion of neighborhood is to be considered in an extensive way: it involves, starting from a given socket (socket activated for charging) of all the sockets in the park, considering the sockets in the park which are within "direct" range, or antenna range, of the socket in question, that is to say the sockets having the capacity to support communication data traffic (sending and receiving messages / requests), and not only the "neighboring" sockets in the sense of geographical proximity.

[0067] The MGP module, which is essentially a microcontroller, is configured to determine, by analyzing the data flows (requests, etc.) passing between "neighboring" outlets, the best path through the mesh network to reach the internet access point (the mesh network exit point corresponding to an outlet (node) in the network of outlets, equipped with internet communication capabilities). Once the best path is determined, information related to the activated outlet is transmitted to a dedicated remote server: vehicle charging, vehicle unplugged, charging complete, power consumption, etc.

[0068] To find the best path, each outlet, via its management and control module, makes a judgment based on several criteria, including:

[0069] - Its connectivity with other sockets in the park, which depends in particular on the propagation conditions of electromagnetic waves in the environment of the socket;

[0070] - Its connectivity to the Internet network, possibly including the connection speed as an indication; and

[0071] - The number of successive sockets (additional intermediate sockets) through which the plug must pass from a neighboring socket to access the Internet network.

[0072] The detailed operation of the mesh network is described below, in which each outlet in the outlet park is considered as a node of the mesh network.

[0073] In practice, each socket indicates to its neighbors whether it has access to the Internet network or not, possibly with an indicative quality of service which may vary depending on congestion or mutual electromagnetic interference, or the load induced on the management and control module of the socket in question, by all the traffic: its own traffic and that of the other sockets within the mesh network.

[0074] Then, the management and control module for each socket chooses the path in the mesh network to the Internet access point (LTE output socket) through which it will exchange information with at least one remote server responsible for controlling the socket (Outlet Manager): "vehicle charging", "vehicle unplugged", "charging complete", "electrical consumption", ...

[0075] The choice of management and control module then involves a trade-off between using many intermediaries (intermediate outlets) with better quality of service or using fewer intermediaries even if they have a lower quality of service in terms of bandwidth in particular.

[0076] Quality of service in a communication network typically refers to an indication qualifying the integrity of data packets, latency, throughput and jitter during a data exchange on the network.

[0077] In the example configuration of [Fig.2], a PPC park with six PC1-PC6 sockets, consisting of four Wifi sockets PC2, PC3, PC4 and PC6 and two LTE sockets, PCI and PC5, is shown to describe the operation of the Wifi mesh network in the charging system according to the invention.

[0078] To simplify, we assume that access to the RCD Internet network is only possible from the two LTE ports (network access points), PCI and PC5.

[0079] For simplicity, it is also assumed that sockets can only communicate with their neighbors in the immediate geographical vicinity (which is not necessarily the case as already explained above).

[0080] Connection speeds are also considered, as an indication, but it is possible to do without them and only consider the number of intermediaries and connectivity with the different neighboring sockets.

[0081] When the PC2 port, which is not an LTE port, is activated, it retrieves information about its immediate neighbors: the PCI and PC3 ports. The PCI and PC3 ports exchange information about their connectivity with the PC2 port, and the PC2 port quantifies its connectivity with the PCI and PC3 ports.

[0082] The PCI socket (LTE socket) informs the PC2 socket that it has direct internet access ("0" additional intermediate and indicative with a speed of IMO / s) and the PC3 socket informs the PC2 socket that it has internet access but with "1" additional intermediate and a significantly lower speed of 0.8 MB / s: the PC3 socket goes through the PC5 socket (LTE socket) to connect to the RCD internet.

[0083] In the example considered, the PC2 socket favors the path passing through the PC3 socket and then through the PC5 socket (LTE socket) because its connectivity is better with the PC3 socket than with the PCI socket (LTE socket), even though the number of additional intermediaries is greater: "1" additional intermediary passing through the PC3 socket versus "0" additional intermediary passing through the PCI socket (LTE socket), and the Internet connection speed is significantly lower: 0.8 MB / s versus 1 MB / s.

[0084] The communication route is represented on [Eig.2], by a succession of solid arrows.

[0085] The PC2 socket chooses its path by making a trade-off between the different pieces of information it has at time T. The information obtained by the PC2 socket: connectivity with its neighbors in the mesh network, number of additional intermediaries between the PC2 socket and an LTE socket (Internet access point) and, as an indication, the internet connection speed of its neighbors.

[0086] This information will vary over time and the PC2 socket will therefore have to change its path regularly to maximize its connectivity in the mesh network.

[0087] Figure 3 illustrates the same example configuration as Figure 2, but now assuming that connectivity is better with the PCI socket (LTE socket) than with the PC3 socket, but with a significantly lower Internet connection rate than with the PC3 socket: 0.3 MB / s with the PCI socket versus IMO / s with the PC3 socket.

[0088] On the other hand, there is no connectivity between the PC3 and PC5 sockets (LTE sockets). Therefore, PC3 can no longer exchange data with PC5 (LTE sockets): there is an obstacle between the two sockets, for example, a parked or passing vehicle, which temporarily blocks the Wi-Fi signal.

[0089] In this case, the PC3 socket goes through the PC4 socket then through the PC6 socket and finally the PC5 socket (LTE socket); which adds two additional intermediates PC4 and PC6 compared to the situation in [Fig.2] (“3” additional intermediates instead of just one).

[0090] The PC2 socket, in its arbitration, favoured the best Internet connection speed.

[0091] Each of the sockets in the socket park behaves exactly like the PC2 socket and the LTE sockets also take into account the fact that they can access the Internet directly.

[0092] Figure 4 illustrates a flowchart of the main steps of a process implemented by the MGP module of each PCn ​​socket in a charging system according to the invention and whose numerical references of the sockets correspond, for guidance purposes, to the example in Figure 2.

[0093] In a first step 100, each PCn ​​outlet indicates to neighboring PCn outlets its ability to access an RCD data communication network, including the Internet network, either directly or via at least one other PCn outlet in the PPC park with a determined PCn outlet communication path.

[0094] And, in a second step 200, when a PC2 socket is activated for a recharge, it chooses a predetermined path from among the communication paths defined by the available neighboring PCI or PC3 socket(s) to connect to the dedicated remote server OM2 via the RCD data communication network, depending on the quality of connectivity of the activated PC2 socket with its available neighboring PCI, PC3 sockets and the number of additional intermediate PCn sockets required relative to each of the available neighboring PCI or PC3 sockets to access the RCD data communication network and, optionally, depending on the connection rate with the RCD data communication network.

[0095] The SYS charging system according to the invention makes it possible to optimize communication between each PCn ​​socket of a park of connected PPC electric charging sockets which can include many low or medium power sockets, with remote OMn charging control servers.

[0096] PCn sockets are fully configurable and remotely manageable thanks to optimized connectivity management and knowledge of socket availability at all times.

[0097] The SYS charging system according to the invention makes it possible to facilitate data exchanges between the PCn sockets of the same PPC park with remote control servers OMn and an SBO supervision server and makes it possible in particular to facilitate the definition and remote deployment of management rules for parks of sockets using a large number of sockets in parks to implement a dynamic allocation of available power (load shedding), in order to meet the sizing and capacity constraints of the electrical distribution network.

[0098] A typical use of a charging system according to the invention is described below.

[0099] When the socket to which a user plugs their vehicle is identified as functional by the monitoring server, the user connects to it using a socket identification method such as a QR code or any other means of identification, code entry, smart subscription card, etc.

[0100] Depending on the circumstances, the user may or may not be required to pay for their top-up.

[0101] When no more current is drawn (for example the vehicle has been unplugged or it is fully charged), the socket sends the information back to the park supervision server via the socket management server, which can then start a new charging session on another socket in the park, within the limit of the “power” budget of the electrical installation.

[0102] Finally, the invention relates to a computer program product comprising instructions which, when the program is executed by a computer, or at least a computer in the management and control module, lead the latter to implement the steps of the process as described above.
