Description

Title of the invention: Method for pairing an electric vehicle charging station with a network of at least one charging station, associated network and method for managing the energy of such a network of charging stations. technical field

[0001] The invention relates, in general, to the management of a charging station for electric and / or hybrid vehicles.

[0002] The invention relates more specifically to the constitution of a communication network between the terminals of a station.

[0003] The invention relates more particularly to a method of pairing a new charging station to a network of one or more charging stations of the same station. Previous techniques

[0004] In recent years, electric and hybrid vehicles have been taking up an increasing place in the automotive environment, and have become more widespread.

[0005] As a result, an increasing number of such vehicles are being put into circulation, whether in town or outside urban areas.

[0006] These vehicles, which operate on electrical energy stored in batteries, periodically require these batteries to be recharged.

[0007] This recharging is carried out by connecting the vehicle to a charging station connected to an electrical source.

[0008] Similar to petrol stations for internal combustion engine vehicles, stations including numerous electric charging points are being deployed in territories to meet the growing needs of motorists.

[0009] Within a charging station, the charging points need to communicate with each other and / or with a station management center. The station management center is, for example, an industrial computer or a programmable logic controller installed locally on the station to ensure, in particular, the local supervision of the charging points and / or the local energy management of the station.

[0010] In the current state, the terminals of a station are each connected by wire to a network switch which is itself connected to a gateway giving access to the internet such as a modem, the terminals being further connected by wire to the local management center of the station.

[0011] This architecture has many drawbacks. Indeed, a significant amount of cabling is required, and the architecture necessitates the installation of a cabinet Local control is required to house the network switch and internet gateway. Furthermore, this architecture necessitates a network configuration using the internet protocol suite, TCP / IP, which can be costly and complex to implement. In addition, this architecture makes adding an extra access point to the station difficult.

[0012] On the other hand, since such an architecture is centralized locally, a single failure in the central node, consisting in particular of the modem, can render the entire station unusable.

[0013] Finally, this architecture implies an important coupling between the software and suppliers of the charging stations on the one hand, and the management center on the other.

[0014] The present invention therefore aims to overcome the aforementioned drawbacks and to propose a method of pairing a charging station with a network of stations, and an improved corresponding network.

[0015] The present invention thus relates to a method for pairing an electric vehicle charging station or a repeater with a communication network of at least one charging station, comprising the following steps:

[0016] - Installation of the charging station to be paired in a geographical area around of a charging station in the network with a radius less than a predefined maximum distance between two charging stations in the network.

[0017] - Power supply for the charging station to be paired,

[0018] - Activation of a first operating mode on a first terminal of the network, the first mode remaining activated for a predefined period.

[0019] - Issuance of an activation command for the first operating mode by the first terminal of the network to the other terminals of the network, in the case where the network includes other charging stations,

[0020] - Activation of the first operating mode of the other network terminals after reception of the activation signal,

[0021] - Emission of an activation signal for the first operating mode by the network terminals,

[0022] - Activation of the first operating mode on the charging station to be paired during the activation of the first operating mode on the first terminal of the network,

[0023] - Pairing of the terminal to be paired and the network terminals, the pairing being carried out during the activation of the first mode on all network terminals and the terminal to be paired.

[0024] Advantageously, the paired terminals are configured to disconnect from the network in a second operating mode.

[0025] Preferably, pairing a repeater to the network is identical to pairing a charging station.

[0026] Advantageously, the preset duration is 5 to 10 seconds.

[0027] Preferably, the activation signal is audible or visual.

[0028] Advantageously, the maximum predefined distance between two charging stations in the network is ten to fifteen meters.

[0029] The invention also relates to a communication network between one or more electric charging stations, the stations being paired with each other according to the process defined above, the network being a mesh network.

[0030] The invention also relates to a method for managing the energy delivered by a charging point in a charging station for electric vehicles, the charging points of the station being paired according to the method defined above and forming a communication network as defined above, comprising the following steps:

[0031] - Definition of an initial configuration of energy management parameters,

[0032] - Communication of the initial configuration to all terminals of the station by the network intermediary,

[0033] - Local storage of the initial configuration by each network terminal,

[0034] - Connecting or disconnecting an electric vehicle at a first charging station the station,

[0035] - Determination of the power requirement to be delivered from the first terminal,

[0036] - Retrieval by the first terminal of energy usage data from the others terminals of the station via the network,

[0037] - Determination of the available power to be delivered by the first terminal depending on the determined power requirement, the energy usage data collected, and the initial configuration defined,

[0038] - Determination of a corrected power output to be applied by each of the other terminals of the station delivering power based on the power available to be delivered by the first determined terminal, the energy usage data retrieved and the initial configuration defined.

[0039] - Recovery by the other terminals of the station of their corrected power to be delivered and the power available to be delivered by the first terminal,

[0040] - Application by the other terminals of the station of their corrected power to be delivered retrieved,

[0041] - Transmission to the first terminal of a confirmation of application of the power to be delivered, corrected by each of the other terminals of the station.

[0042] - Charging the electric vehicle via the first charging station according to the power available to be delivered determined.

[0043] Advantageously, the energy management parameters forming the initial configuration include a type of power setpoint to be delivered by each of the terminals and a protocol for managing the priority of access to energy by the terminals of the station.

[0044] Preferably, the type of power setpoint to be delivered is static or dynamic. Brief description of the drawings

[0045] Other objects, features and advantages of the invention will become apparent from the following description, given solely by way of non-limiting example, and made with reference to the accompanying drawings in which:

[0046] [Fig.l] schematically illustrates a charging station for electric and / or hybrid vehicles and a network according to the invention;

[0047] [Fig.2] illustrates a method of pairing a charging station with the network of stations of the [Fig.1] station according to the invention;

[0048] [Fig.3] illustrates a method of managing the energy delivered by a terminal of the station according to the invention. Detailed description of at least one embodiment

[0049] Figure 1 schematically represents a charging station 1 for electric vehicles. The station 1 thus comprises one or more charging points 2 for electric vehicles, each powered by energy from an energy reserve 3 of the station 1.

[0050] The charging stations 2 are paired with each other according to a pairing procedure illustrated schematically in [Fig. 2], to form a communication network 4 between them. The pairing procedure will be described below, using as an illustrative example the pairing of a new station 2a not yet paired with the network 4.

[0051] The terminal 2a to be paired is identical to the terminals 2 already paired forming the network 4, so that the following description of each of the terminals 2 of the network 4 applies to the terminal to be paired 2a.

[0052] Each of the charging stations 2 of the network 4 is configured to communicate by telecommunications techniques with remote objects or servers.

[0053] In particular, each of the terminals 2 is configured to communicate with these remote objects or servers via medium-range wireless telecommunications techniques, on the order of 10 to 20 meters. Preferably, the terminals 2 use the BLE telecommunications protocol, an acronym for the Anglo-Saxon name Bluetooth Low Energy, and also called in French Bluetooth à basse consommation or Bluetooth à basse énergie.

[0054] Alternatively, the terminals 2 can also use the Bluetooth protocol. In other words, each of the terminals 2 is configured to communicate with the objects remote devices located at medium distances and capable of communicating on the 2.4 GHz frequency band.

[0055] In particular, each of the charging stations 2 is configured to communicate over a medium distance with another identically configured charging station 2. Each charging station 2 is therefore capable of communicating with another charging station 2 via a common medium-range wireless telecommunication protocol, on the order of 10 to 20 meters, such as Bluetooth Low Energy or Bluetooth.

[0056] Each of the terminals 2 is configured to operate according to a first operating mode called pairing mode and according to a second operating mode called unpairing mode.

[0057] More specifically, in the first operating mode called pairing mode, a terminal 2 is able to pair with another terminal 2 also operating in the first operating mode and / or with a network of terminals 2 whose terminals also operate in the first operating mode.

[0058] In other words, a terminal 2 already paired with network 4 operating in the first mode is able to detect a new terminal 2a not yet paired with network 4 also operating in the first mode of operation, and to pair this new terminal 2a with network 4.

[0059] Correspondingly, a new terminal 2a not paired with network 4 and operating in the first mode of operation is capable of being paired with network 4 by at least one terminal 2 operating in the first mode of operation.

[0060] The simultaneous activation of the first operating mode of two unpaired terminals 2 and 2a located at a communication distance from each other therefore causes the two terminals 2 to pair with each other. Similarly, the simultaneous activation of the first operating mode of the terminals 2 of network 4 and of a terminal 2a not paired with network 4 causes the new terminal 2a to pair with network 4.

[0061] The activation of the first operating mode is achieved by means of a switching means not accessible to the public of station 1 such as a button.

[0062] When the switching means for terminal 2 is activated, terminal 2 begins to operate according to the first operating mode. The first mode of terminal 2 is continuously activated for a predefined duration from the activation of the switching means, so as to allow sufficient time for the activation of the first mode on the other terminal(s) with which said terminal 2 is to be paired.

[0063] For example, the preset duration is 30 to 80 seconds, and preferably 60 seconds.

[0064] Upon expiry of the predefined time, the first operating mode is deactivated, and a terminal 2 is no longer able to pair itself and be paired to a network.

[0065] In the second operating mode, called unpairing mode, a terminal 2 already paired with network 4 can unpair itself from network 4, that is to say that a terminal 2 operating in the second operating mode is configured to unlink itself from a terminal 2 and / or a network 4 of terminals to which it was previously paired.

[0066] Figure 2 schematically illustrates the steps of a method for pairing a new charging station 2a with the network 4 of at least one charging station 2. As described above, the new charging station 2a is substantially identical to the other stations 2. In other words, the station 2a to be paired is configured to operate according to the first operating mode, called pairing, and according to the second operating mode, called unpairing. In addition, the station 2a to be paired is also configured to communicate over a medium range with another identically configured station 2.

[0067] In a first step El, the charging station to be paired 2a is installed in a geographical area delimited by a predefined radius around a station 2 already paired to the network 4. In the case where the station 2a is the first station to be paired, i.e. that the network includes only one station 2, the step El consists of installing the charging station to be paired 2a in a geographical area around the station 2.

[0068] The predefined radius delimiting the geographical area is defined by the maximum distance allowed by the telecommunications protocol used jointly by the charging stations 2 to communicate with each other. Thus, the predefined radius is between 10 and 20 meters, corresponding to the range of communication between two objects using a medium-range wireless communication protocol.

[0069] Terminal 2a is therefore installed, for example, 10 meters from one of the terminals 2 of network 4.

[0070] During its installation, terminal 2a is connected to the energy reserve 3 of station 1 so as to supply terminal 2a with energy.

[0071] In a second step E2, terminal 2a is therefore supplied with energy.

[0072] In a third step E3, the first operating mode is activated on a first terminal 2b among the terminals 2 of network 4. The first terminal 2b then operates according to the first operating mode for the predefined duration.

[0073] In a fourth step E4, the first terminal 2b operating in the first mode of operation sends an activation order for the first mode to all the other terminals 2 in the network 4. This activation order is communicated to the other terminals 2 in the network 4 via the joint communication protocol used by the terminals 2 in the network 4 to communicate with each other.

[0074] In a fifth step E5, the other terminals 2 of the network 4 receive the activation command for the first mode issued in step E4, and then switch to operation according to the first operating mode. The first operating mode is then activated on all the terminals 2 of the network 4.

[0075] In a sixth step E6, each of the terminals 2 of the network 4 emits an activation signal of the first operating mode, this signal being visual and / or audible so as to warn a technician that the network 4 is ready to pair the new terminal 2a to be paired.

[0076] In a seventh step E7, the first operating mode is activated on terminal 2a to be paired.

[0077] In a final step E8, the terminal to be paired 2a is therefore paired with the terminals 2 of the network 4. More precisely, pairing E8 is only performed if step E7, which activates the first mode of the terminal 2a to be paired, is implemented during the activation of the first mode of the first terminal 2b, that is, during the predefined duration following step E3. Indeed, if step E7 is implemented after the predefined duration following the implementation of step E3, that is, if the first operating mode is activated on the terminal 2a to be paired after the expiration of the predefined activation duration of the first operating mode of the first terminal 2b, the first terminal 2b no longer operates according to the first mode and therefore cannot pair with the new terminal 2a to be paired.

[0078] The pairing of the terminal to be paired 2a with the network 4 is therefore necessarily carried out during the activation of the first operating mode of the first terminal 2b.

[0079] Pairing is confirmed for example by the emission of a pairing confirmation signal by terminal 2a.

[0080] Thus, the paired terminals 2 of station 1 form the network 4 of terminals. Each terminal 2 of network 4 is therefore installed within communication range of another terminal 2 of network 4, that is, at a distance of 10 to 20 meters. Each terminal 2 of network 4 can therefore communicate directly with one or more other terminals 2 of network 4, via the communication protocol jointly used by the terminals 2 of network 4.

[0081] The set of terminals 2 of station 1 therefore forms a wireless network 4 whose topology is meshed, and in which each of the terminals 2 constitutes a node of the network 4. A communication between two terminals 2 of the network 4 is therefore done by a series of point-to-point links between neighboring terminals 2 of the network 4, the routing of data packets being carried out by each of the terminals 2 transiting the packet autonomously step-by-step to a neighboring terminal 2.

[0082] Such a network therefore makes it possible to limit cabling, facilitates the addition of a new terminal, and is more resistant to the failure of one of the elements of the network.

[0083] In the case where the terminal 2a to be paired has to be installed at a location outside the predefined radius geographical area around one of the terminals 2, it is possible to pair a repeater to the network according to the same process of [Fig.2] at a given location so that the repeater is positioned within range of terminal 2a and another repeater of network 4 or of one of the terminals 2 of network 4.

[0084] Some of the network terminals 2 may include a network access means allowing, for example, connection to external networks such as the Internet and / or remote servers. In this case, each of the network terminals 2 can transmit and / or receive data from these external networks via said terminals 2 comprising the network access means. Such Internet access can notably be used for remote management and / or maintenance of station 1.

[0085] The pairing method of [Fig.2] can also be used to pair a management and / or maintenance node to the network 4, for example consisting of an industrial computer and / or a smartphone with the required permissions.

[0086] In addition, such a meshed network 4 facilitates maintenance, as information and / or configurations can be transmitted to all terminals 2 of the network 4 more reliably.

[0087] Such a network 4 of terminals 2 paired with each other according to the pairing process illustrated in [Fig.2] is usable within the framework of a process for managing the energy delivered by one of the terminals 2 of station 1 for the charging of an electric vehicle.

[0088] One of the challenges of a charging station such as station 1 is the local management of its energy consumption.

[0089] Indeed, several constraints weigh on the management of energy consumption and increase its importance. First, energy supply is costly. Moreover, it is common for the network power available at a station such as station 1, that is to say the amount of power that can be delivered simultaneously by the terminals 2 of station 1, to be less than the sum of the possible powers of each terminal 2 of station 1, that is to say the sum of the amounts of power that can be individually delivered by each of the terminals 2 of station 1.

[0090] As a reminder, power is the quantity of energy per unit of time. Thus, it is known to describe a charging operation of a hybrid and / or electric vehicle using terms relating to power and / or energy.

[0091] Finally, local energy management is essential due to the complexity of its storage and production.

[0092] In a first step E9 of the process of managing the energy delivered by a terminal 2 of station 1, an initial configuration of energy management parameters is defined.

[0093] More specifically, the initial configuration of energy management parameters allows for the definition of a set of predefined rules and parameters organizing the energy management of station 1.

[0094] The initial configuration of energy management parameters thus includes a protocol for managing the priority of access to energy by the terminals 2 of station 1, and a definition of a type of power setpoint to be delivered by each of the terminals 2 of station 1.

[0095] The protocol for managing priority access to energy by the terminals 2 of station 1 defines the common priority management rules that the terminals 2 must follow for accessing energy. More specifically, an example of a rule to be followed could be a priority allocation of energy based on the chronological order of energy supply requests by each terminal 2. Alternatively, the protocol for managing priority access to energy by the terminals 2 could define an arbitration based on data such as the energy already delivered by each of the terminals 2 to the charging vehicles, or the charging time already completed by each terminal 2 for the vehicle that has plugged in, etc.

[0096] The access priority management protocol can also define terminals 2 with priority for access to energy.

[0097] The type of power setpoint to be delivered by a terminal 2 is static or dynamic. A static power setpoint means that terminal 2 delivers a constant power, the value of which is predefined by a static setpoint, for example, 150 Amperes per phase. Conversely, a dynamic power setpoint means that terminal 2 delivers a variable amount of power depending on the availability of station 1.

[0098] The initial configuration of energy management parameters is developed locally within station 1, for example via a management node as defined above, or remotely, for example via a remote server and / or the Internet.

[0099] In a second step E10, the initial configuration defined is communicated to all the terminals 2 of station 1 via the network 4, whose mesh topology and wireless communication protocol allow improved, faster and more reliable information transmissions.

[0100] In a third step El 1, the initial configuration is stored locally by each of the terminals 2 of the network 4 of station 1, so that it can be applied in the event of a vehicle being connected.

[0101] In a fourth step E12, a vehicle connects to or disconnects from one of the terminals 2 of station 1. For example, a vehicle connects to or disconnects from the first terminal 2b.

[0102] In a fifth step E13, a power requirement to be delivered is determined for the first terminal 2b on which the vehicle was connected or disconnected in step E12.

[0103] The power requirement to be delivered is an ideal theoretical amount of power that the first terminal 2b should deliver following the connection or disconnection of the vehicle.

[0104] In the case where a vehicle has been plugged in, the power requirement to be delivered is therefore an ideal amount of power that the first terminal 2b should deliver to have an optimized charge, regardless of the conditions of use of the energy available from station 1. An optimized charge of the vehicle is the most efficient charge possible, i.e. the fastest according to the technical characteristics of the terminal 2 and of the vehicle which has been plugged into said terminal 2.

[0105] On the contrary, in the case where a vehicle has disconnected from terminal 2b, the power requirement to be delivered is substantially zero, because no vehicle is now connected to the first terminal 2b, which therefore no longer has to deliver energy.

[0106] The power requirement to be delivered by the first terminal 2b is therefore dependent on the technical characteristics of the vehicle that has connected to the first terminal 2b, such as the maximum power and / or energy limits allowed by said vehicle for its charging, the amount of energy and / or power required by the vehicle for its charging, and the technical characteristics of the terminal 2b, such as the type of power setting to be delivered by the terminal 2b, or the maximum energy and / or power limit that can be delivered by the terminal 2b.

[0107] In a sixth step E14, the first terminal 2b on which the vehicle was plugged in or unplugged in step E13 retrieves energy usage data from the other terminals 2 of station 1 via network 4.

[0108] More specifically, the first terminal 2b sends a signal to connect or disconnect a vehicle to the other terminals 2, which respond by transmitting their respective energy use data.

[0109] The energy usage data of a terminal 2 of the station corresponds to the amount of energy and / or power delivered by said terminal 2. This data is therefore negligible when no vehicle is connected to said terminal 2, and is equal to the amount of power and / or energy currently used for the charging of a vehicle connected to said terminal 2.

[0110] In a seventh step El5, a power available to be delivered by the first terminal 2b on which the vehicle has been connected or disconnected is determined.

[0111] The available power to be delivered is the maximum amount of power that the first terminal 2b can deliver to the vehicle for its charging.

[0112] This term of available power to be delivered by the first terminal 2b is determined according to the energy use data of each of the terminals 2 of the station received in step E14, the initial configuration of the energy management parameters defined in step E9 and stored locally by the first terminal 2b, and the power requirement to be delivered by the first terminal 2b determined in step E13.

[0113] Preferably, this term of power available to be delivered by the first terminal 2b is determined directly by the first terminal 2b.

[0114] In the case where step E12 corresponds to a connection of the vehicle to the first terminal 2b and the energy reserve of station 1 allows it, the power available to be delivered by the first terminal 2b is set at the level of the power requirement to be delivered determined in step E13. Otherwise, the power available to be delivered is set at a lower level.

[0115] In the case where step E12 corresponds to a disconnection of the vehicle from the first terminal 2b, the term of available power to be delivered is substantially negligible and therefore zero.

[0116] In a subsequent step E16, a corrected power to be delivered term is determined for each of the other terminals 2 of station 1. More particularly, a corrected power to be delivered is determined for each of the other terminals 2 of station 1 that are delivering energy, i.e., on which a vehicle is connected, the terminals on which no vehicle is connected do not substantially deliver energy.

[0117] The corrected power to be delivered from a terminal 2 delivering power is determined as a function of the power available to be delivered by the first terminal 2b, the energy use data of each terminal 2 retrieved in step E14, and the initial configuration defined.

[0118] The power to be delivered corrected from a terminal 2 delivering power is preferably determined by the first terminal 2b, in order to limit communications within the network 4.

[0119] More specifically, the first 2b determines for each of the terminals 2 delivering energy a power to be delivered corrected according to the energy that it can deliver to the vehicle, defined by the power available to be delivered by the first terminal 2b, the energy initially delivered by said terminal 2, defined by the energy use data of these terminals 2, and the initial configuration, and in particular the energy access priority management protocol.

[0120] The corrected power to be delivered from terminal 2 therefore makes it possible to adapt the amount of energy and / or power allocated to terminal 2 and delivered by this terminal 2 to the delivery of new energy and / or power from the first terminal 2b. The corrected power to be delivered from a terminal 2 is therefore equal to or greater than the power delivered by said terminal 2 before step E12 when step E12 is a step of disconnecting a vehicle from the first terminal 2b, and is therefore less than or equal to the power delivered by said terminal 2 before step E12 when step E12 is a step of connecting a vehicle to the first terminal 2b.

[0121] In a subsequent step E17, each terminal 2 of the network 4 of station 1 retrieves its corrected power to be delivered determined in step E16, then applies it in a step E18, and issues a confirmation of application of the corrected power to be delivered term to the first terminal 2b in a subsequent step E19.

[0122] Finally, in a final step E20, the first terminal 2b having received confirmations of application of the corrected power to be delivered term from each of the other terminals 2 of station 1, recharges the vehicle according to the available power to be delivered determined in step E15.

[0123] The process in [Fig. 3] is thus repeated each time a vehicle is connected to or disconnected from one of the terminals at station 1. This process allows for improved energy management at station 1, as it is decentralized. Indeed, this process does not require a central energy management center, as this management is carried out directly by each of the terminals at station 1, via network 4.
