Description

[0001] DESCRIPTION

[0002] TITLE: 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.

[0003] Technical field

[0004] The invention relates, in general, to the management of a charging station for electric and / or hybrid vehicles.

[0005] The invention relates more specifically to the constitution of a communication network between the terminals of a station.

[0006] The invention relates more particularly to a method for pairing a new charging terminal to a network of one or more charging terminals at the same station.

[0007] Previous techniques

[0008] In recent years, electric and hybrid vehicles have taken an increasing place in the automotive environment and have become more widespread.

[0009] As a result, an increasing number of such vehicles are being driven, both in cities and outside urban areas.

[0010] These vehicles operate on electrical energy stored in batteries and require periodic recharging of these batteries.

[0011] This recharging is carried out by connecting the vehicle to a charging station connected to an electrical source.

[0012] Like petrol stations for thermal vehicles, stations with numerous electric charging points are being deployed in the regions to meet the growing needs of motorists.

[0013] Within a station, the terminals are required 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, local supervision of the charging terminals and / or local energy management of the station.

[0014] In the current state, the terminals of a station are each connected by wire to a network switch itself connected to a gateway providing access to the Internet such as a modem, the terminals being further connected by wire to the local management center of the station.

[0015] This architecture involves many drawbacks. Indeed, a significant amount of cabling is required, and the architecture requires the installation of a local control cabinet to house the network switch and the internet gateway. In addition, this architecture requires a network configuration using the internet protocol suite, called TCP / IP, which can be expensive and complex to implement. In addition, this architecture makes it difficult to add an additional terminal in the station.

[0016] On the other hand, such an architecture being locally centralized, a single failure in the central node constituted in particular by the modem can render the entire station unusable.

[0017] Finally, this architecture involves significant coupling between the software and suppliers of the charging stations on the one hand, and the management center on the other.

[0018] The present invention therefore aims to overcome the aforementioned drawbacks and to propose a method for pairing a charging terminal with a network of terminals of a station, and an improved corresponding network.

[0019] The present invention thus relates to a method for pairing a charging station of an electric vehicle or a repeater to a communication network of at least one charging station, comprising the following steps:

[0020] - Installation of the charging station to be paired in a geographical area around a network charging station with a radius less than a predefined maximum distance between two network charging stations.

[0021] - Power supply to the charging station to be paired, - Activation of a first operating mode on a first terminal in the network, the first mode remaining activated for a predefined duration.

[0022] - Issuance of an order to activate 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 terminals,

[0023] - Activation of the first operating mode of the other terminals in the network after receiving the activation signal,

[0024] - Emission of an activation signal of the first operating mode by the network terminals,

[0025] - Activation of the first operating mode on the charging station to be paired during the activation of the first operating mode on the first station in the network,

[0026] - 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 the network terminals and the terminal to be paired.

[0027] Advantageously, the paired terminals are configured to disconnect from the network in a second operating mode.

[0028] Preferably, pairing a repeater to the network is identical to pairing a charging station.

[0029] Advantageously, the predefined duration is 5 to 10 seconds.

[0030] Preferably, the activation signal is sound or light.

[0031] Advantageously, the maximum predefined distance between two charging stations in the network is ten to fifteen meters.

[0032] 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 method defined above, the network being a mesh network.

[0033] The invention also relates to a method for managing the energy delivered by a charging terminal of a charging station for an electric vehicle, the terminals of the station being paired according to the method defined previously and forming a communication network as defined previously, comprising the following steps: - Definition of an initial configuration of energy management parameters,

[0034] - Communication of the initial configuration to all the station terminals via the network,

[0035] - Local storage of the initial configuration by each terminal of the network,

[0036] - Connecting or disconnecting an electric vehicle to a first terminal at the station,

[0037] - Determination of a power requirement to be delivered from the first terminal,

[0038] - Recovery by the first terminal of energy usage data from the other terminals of the station via the network,

[0039] - Determination of an available power to be delivered by the first terminal based on the power requirement to be delivered determined, the energy usage data recovered and the initial configuration defined,

[0040] - Determination of a corrected power to be delivered to be applied by each of the other terminals of the station delivering power according to the power available to be delivered by the first terminal determined, the recovered energy usage data and the initial configuration defined.

[0041] - Recovery by the other terminals of the station of their corrected power to be delivered and of the power available to be delivered by the first terminal,

[0042] - Application by the other terminals of the station of their corrected recovered power to be delivered,

[0043] - 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,

[0044] - Recharging of the electric vehicle by the first terminal depending on the power available to be delivered determined.

[0045] Advantageously, the energy management parameters forming the initial configuration comprise a type of power instruction 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. Preferably, the type of power instruction to be delivered is static or dynamic.

[0046] Brief description of the drawings

[0047] Other aims, characteristics and advantages of the invention will appear on reading the following description, given solely by way of non-limiting example, and made with reference to the appended drawings in which:

[0048] [Fig l] schematically illustrates a charging station for electric and / or hybrid vehicles and a network according to the invention;

[0049] [Fig2] illustrates a method of pairing a charging terminal to the network of terminals of the station of figure 1 according to the invention;

[0050] [Fig3] illustrates a method for managing the energy delivered by a terminal of the station according to the invention.

[0051] Detailed description of at least one embodiment

[0052] Figure 1 schematically shows a charging station 1 for electric vehicles. The station 1 thus comprises one or more charging terminals 2 for electric vehicles, each supplied with energy from an energy reserve 3 of the station 1.

[0053] The charging terminals 2 are paired with each other according to a pairing method illustrated schematically in Figure 2, to form a communication network 4 between them. The pairing method will be described below, taking as an illustrative example the pairing of a new terminal 2a not yet paired with the network 4.

[0054] Terminal 2a to be paired is identical to the terminals 2 already paired forming network 4, so that the following description of each of the terminals 2 of network 4 applies to terminal 2a to be paired.

[0055] Each of the charging stations 2 of the network 4 is configured to communicate by telecommunications techniques with remote objects or servers.

[0056] In particular, each of the terminals 2 is configured to communicate with these remote objects or servers via wireless telecommunications techniques at medium distances, of the order of 10 to 20 meters. Preferably, the terminals 2 use the BLE telecommunications protocol, an acronym for the English term Bluetooth Low Energy, and also called in French Bluetooth à basse consommation or Bluetooth à basse énergie.

[0057] Alternatively, the terminals 2 can also use the Bluetooth protocol. In other words, each of the terminals 2 is configured to communicate with remote objects located at medium distance and capable of communicating on the 2.4 GHz frequency band.

[0058] In particular, each of the charging terminals 2 is configured to communicate over a medium distance with another identically configured terminal 2. Each charging terminal 2 is therefore capable of communicating with another charging terminal 2 via a common wireless telecommunications protocol over a medium distance, of the order of 10 to 20 meters, such as low-energy Bluetooth or Bluetooth.

[0059] 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.

[0060] More precisely, in the first operating mode called pairing mode, a terminal 2 is capable of pairing 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.

[0061] In other words, a terminal 2 already paired with network 4 operating in the first mode is capable of detecting a new terminal 2a not yet paired with network 4 also operating in the first operating mode, and of pairing this new terminal 2a with network 4.

[0062] Correspondingly, a new terminal 2a not paired with the network 4 and operating in the first operating mode is capable of being paired with the network 4 of at least one terminal 2 operating in the first operating mode.

[0063] The simultaneous activation of the first operating mode of two unpaired terminals 2 and 2a located within communication distance of each other therefore causes the pairing of the two terminals 2 with each other. Similarly, the simultaneous activation of the first operating mode of terminals 2 of network 4 and of a terminal 2a not paired with network 4 causes the pairing of the new terminal 2a with network 4.

[0064] Activation of the first operating mode is carried out by means of a switching means not accessible to the public of station 1 such as a button.

[0065] When the switching means of a terminal 2 is activated, the terminal 2 begins to operate according to the first operating mode. The first mode of a terminal 2 is activated continuously for a predefined duration from the activation of the switching means, so as to leave sufficient time to allow the activation of the first mode on the other terminal(s) with which it is desired to pair said terminal 2.

[0066] For example, the preset duration is 30 to 80 seconds, and preferably 60 seconds.

[0067] At the end of the predefined duration, the first operating mode is deactivated, and a terminal 2 is no longer able to pair and be paired to a network.

[0068] In the second operating mode, called unpairing mode, a terminal 2 already paired with the network 4 can unpair from the network 4, that is to say that a terminal 2 operating in the second operating mode is configured to unpair from a terminal 2 and / or from a network 4 of terminals to which it was previously paired.

[0069] Figure 2 schematically illustrates the steps of a method for pairing a new charging station 2a to 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 at medium distance with another station 2 identically configured.

[0070] In a first step E1, the charging terminal to be paired 2a is installed in a geographical area delimited by a predefined radius around a terminal 2 already paired to the network 4. In the case where the terminal 2a is the first terminal to be paired, that is to say that the network only comprises a single terminal 2, step E1 consists of installing the terminal to be paired 2a in a geographical area around the terminal 2.

[0071] 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-distance wireless communication protocol.

[0072] Terminal 2a is therefore installed, for example, 10 meters from one of terminals 2 of network 4.

[0073] During its installation, terminal 2a is connected to the energy reserve 3 of station 1 in order to supply terminal 2a with energy.

[0074] In a second step E2, terminal 2a is therefore supplied with energy.

[0075] In a third step E3, the first operating mode is activated on a first terminal 2b among the terminals 2 of the network 4. The first terminal 2b then operates according to the first operating mode for the predefined duration.

[0076] In a fourth step E4, the first terminal 2b operating in the first operating mode sends an activation order for the first mode to all the other terminals 2 of the network 4. This activation order is communicated to the other terminals 2 of the network 4 via the communication protocol jointly used by the terminals 2 of the network 4 to communicate with each other.

[0077] In a fifth step E5, the other terminals 2 of the network 4 receive the activation order of the first mode sent 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.

[0078] In a sixth step E6, each of the terminals 2 of the network 4 emits a signal for activating the first operating mode, this signal being luminous and / or audible so as to warn a technician that the network 4 is capable of pairing the new terminal 2a to be paired.

[0079] In a seventh step E7, the first operating mode is activated on the terminal 2a to be paired. In a final step E8, the terminal to be paired 2a is therefore paired with the terminals 2 of the network 4. More precisely, the pairing E8 is only carried out if the step E7 of activating 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 to say during the predefined duration following the step E3. Indeed, in the case where step E7 is implemented after the predefined duration following the implementation of step E3, that is to say in the case where the first operating mode is activated on the terminal 2a to be paired after the expiry of the predefined duration of activation of the first operating mode of the first terminal 2b, the first terminal 2b no longer operates according to the first mode and can therefore not pair with the new terminal 2a to be paired.

[0080] 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.

[0081] Pairing is confirmed, for example, by the emission of a pairing confirmation signal by terminal 2a.

[0082] Thus, all the terminals 2 of station 1 paired together form the network 4 of terminals. Each of the terminals 2 of the network 4 is therefore installed within communication range of another terminal 2 of the network 4, i.e. at a distance of 10 to 20 meters. Each of the terminals 2 of the network 4 can therefore communicate directly with one or more other terminals 2 of the network 4, via the communication protocol jointly used by the terminals 2 of the network 4.

[0083] All of the terminals 2 of the station 1 therefore form a wireless network 4 whose topology is meshed, and in which each of the terminals 2 constitutes a node of the network 4. Communication between two terminals 2 of the network 4 is therefore carried out by a series of point-to-point links between neighboring terminals 2 of the network 4, the routing of the data packets being carried out by each of the terminals 2 transiting the packet autonomously step-by-step to a neighboring terminal 2.

[0084] Such a network therefore makes it possible to limit wiring, facilitates the addition of a new terminal, and is more resistant to the failure of one of the network elements.

[0085] In the case where the terminal 2a to be paired must be installed at a location outside the predefined geographic radius zone around one of the terminals 2, it is possible to pair a repeater to the network according to the same method of figure 2 at a given location so that the repeater is positioned within range of the terminal 2a and another repeater of the network 4 or one of the terminals 2 of the network 4.

[0086] Some of the terminals 2 of the network may comprise a network access means making it possible, for example, to connect to external networks such as the Internet network and / or remote servers. In this case, each of the terminals 2 of the network 4 may transmit and / or receive data originating from these external networks, via said terminals 2 comprising the network access means. Such Internet access may in particular be used for remote management and / or maintenance of the station 1.

[0087] The pairing method of Figure 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 having the required authorizations.

[0088] Furthermore, 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.

[0089] Such a network 4 of terminals 2 paired together according to the pairing method illustrated in FIG. 2 can be used as part of a method for managing the energy delivered by one of the terminals 2 of the station 1 for recharging an electric vehicle.

[0090] One of the challenges of a charging station such as station 1 is the local management of its energy consumption.

[0091] Indeed, several constraints weigh on the management of energy consumption and increase its importance. First of all, the supply of energy is expensive. In addition, it is common for the network power available on a station such as station 1, that is to say the quantity of power that can be delivered simultaneously by the terminals 2 of station 1, to be lower than the sum of the possible powers of each terminal 2 of station 1, that is to say the sum of the quantities of power that can be individually delivered by each of the terminals 2 of station 1.

[0092] As a reminder, power is the amount of energy per unit of time. Thus, it is known to describe a recharging operation of a hybrid and / or electric vehicle using terms relating to power and / or energy.

[0093] Finally, local energy management is essential due to the complexity of its storage and production.

[0094] In a first step E9 of the method for managing the energy delivered by a terminal 2 of the station 1, an initial configuration of energy management parameters is defined.

[0095] More specifically, the initial configuration of energy management parameters allows defining a set of predefined rules and parameters organizing the energy management of station 1.

[0096] The initial configuration of energy management parameters thus includes a protocol for managing the priority of access to energy by terminals 2 of station 1, and a definition of a type of power instruction to be delivered by each of terminals 2 of station 1.

[0097] The protocol for managing priority access to energy by terminals 2 of station 1 defines the common priority management rules to be respected by terminals 2 for access to energy. More specifically, an example of a rule to be respected may be a priority allocation of energy based on the chronological order of requests for energy supply by each terminal 2. Alternatively, the protocol for managing priority access to energy by terminals 2 may define an arbitration based on data such as the energy already delivered by each of the terminals 2 to the vehicles being charged or the charging time already carried out by each of the terminals 2 for the vehicle having connected to it, etc.

[0098] The access priority management protocol can also define priority 2 terminals for energy access.

[0099] The type of power setpoint to be delivered by terminal 2 is static or dynamic. A static type of power setpoint to be delivered means that terminal 2 delivers a constant power, the value of which is predefined by a static setpoint, for example 150 Amps per phase. On the contrary, a dynamic type of power setpoint to be delivered means that terminal 2 delivers a power in a variable quantity depending on the availability of station 1.

[0100] 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.

[0101] In a second step E 10, the initial configuration defined is communicated to all the terminals 2 of the station 1 via the network 4, whose mesh topology and wireless communication protocol allow improved, faster and more reliable transmissions of information.

[0102] In a third step E li , the initial configuration is stored locally by each of the terminals 2 of the network 4 of the station 1 , so that it can be applied in the event of a vehicle being connected.

[0103] In a fourth step E 12, a vehicle connects to one of the terminals 2 of the station 1, or disconnects. For example, a vehicle connects to the first terminal 2b or disconnects from it.

[0104] In a fifth step E 13 , a power requirement to be delivered is determined for the first terminal 2b to which the vehicle was connected or disconnected in step E 12.

[0105] The power requirement to be delivered is an ideal theoretical quantity of power that the first terminal 2b should deliver following the connection or disconnection of the vehicle.

[0106] In the case where a vehicle has connected, the power requirement to be delivered is therefore an ideal quantity of power that the first terminal 2b should deliver to have an optimized recharge, independently of the conditions of use of the energy available from station 1. An optimized recharge of the vehicle is the most efficient possible recharge, that is to say the fastest depending on the technical characteristics of terminal 2 and the vehicle having connected to said terminal 2.

[0107] On the contrary, in the case where a vehicle has disconnected from terminal 2b, the power requirement to be delivered is practically zero, because no vehicle is now connected to the first terminal 2b, which therefore no longer has to deliver energy.

[0108] The power requirement to be delivered by the first terminal 2b is therefore dependent on the technical characteristics of the vehicle connected to the first terminal 2b, such as the maximum power and / or energy limits permitted by said vehicle for its recharging, the quantity of energy and / or power required by the vehicle for its recharging, and the technical characteristics of the terminal 2b, such as the type of power instruction to be delivered from the terminal 2b, or the maximum energy and / or power limit that can be delivered by the terminal 2b.

[0109] In a sixth step E 14, the first terminal 2b to which the vehicle was connected or disconnected in step E 13 recovers energy usage data from the other terminals 2 of the station 1 via the network 4.

[0110] More precisely, the first terminal 2b sends a signal for connecting or disconnecting a vehicle to the other terminals 2, which respond by transmitting their respective energy usage data.

[0111] The energy usage data of a terminal 2 of the station corresponds to the quantity 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 worth the quantity of power and / or power currently used for recharging a vehicle connected to said terminal 2.

[0112] In a seventh step E 15, a power available to be delivered by the first terminal 2b to which the vehicle is connected or disconnected is determined.

[0113] The power available to be delivered is the maximum amount of power that the first terminal 2b can deliver to the vehicle for recharging.

[0114] This term of power available to be delivered by the first terminal 2b is determined as a function of the energy usage data of each of the terminals 2 of the station received in step E14, of the initial configuration of the energy management parameters defined in step E9 and stored locally by the first terminal 2b, and of the power requirement to be delivered by the first terminal 2b determined in step E13.

[0115] Preferably, this term of power available to be delivered by the first terminal 2b is determined directly by the first terminal 2b. In the case where step E 12 corresponds to a connection of the vehicle to the first terminal 2b and the energy reserve of the station 1 allows it, the power available to be delivered by the first terminal 2b is fixed at the level of the power requirement to be delivered determined in step E 13. Otherwise, the power available to be delivered is fixed at a lower level.

[0116] In the case where step E 12 corresponds to a disconnection of the vehicle from the first terminal 2b, the term of power available to be delivered is substantially negligible and therefore zero.

[0117] In a following step E 16, a corrected power to be delivered term is determined for each of the other terminals 2 of the station 1. More particularly, a corrected power to be delivered is determined for each of the other terminals 2 of the station 1 in the process of delivering energy, i.e. to which a vehicle is connected, the terminals to which no vehicle is connected delivering substantially no energy.

[0118] 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 usage data of each terminal 2 recovered in step E 14, and the initial configuration defined.

[0119] The corrected power to be delivered from a terminal 2 delivering power is preferably determined by the first terminal 2b, in order to limit communications within the network 4.

[0120] More precisely, the first 2b determines for each of the terminals 2 delivering energy a power to be delivered corrected as a function of the energy that it can deliver to the vehicle, defined by the power available to be delivered by the first terminal 2b, of the energy delivered initially by said terminals 2, defined by the energy usage data of these terminals 2, and of the initial configuration, and in particular of the energy access priority management protocol.

[0121] The corrected power to be delivered from a terminal 2 therefore makes it possible to adapt the quantity of energy and / or power allocated to the 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.

[0122] In a following step E17, each terminal 2 of network 4 of station 1 recovers 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 following step E19.

[0123] Finally, in a final step E20, the first terminal 2b having received the confirmations of application of the corrected power term to be delivered from each of the other terminals 2 of the station 1, recharges the vehicle according to the available power to be delivered determined in step E15.

[0124] The process of Figure 3 is thus repeated each time a vehicle is connected or disconnected from one of the terminals of station 1. The process thus allows for improved management of the energy of station 1, because it is decentralized. Indeed, it is not necessary in this process to have a central energy management center, this management being carried out directly by each of the terminals of station 1, via network 4.
