Description

Technical Field

[0001] The present invention generally relates to the management of stations for charging terminals for electric and / or hybrid vehicles.

[0002] The present invention more particularly relates to forming a communication network between terminals of a station.

[0003] The invention more particularly relates to a method for pairing a new charging terminal with a network of one or more charging terminals at the same station. Background Art

[0004] Over the past few years, electric vehicles and hybrid vehicles have become increasingly common in the automotive industry and have gained popularity.

[0005] This means that more and more of these vehicles are likely to be on the roads, both in towns and cities and outside of them.

[0006] These vehicles run on electrical energy stored in batteries, so these batteries need to be charged regularly.

[0007] This charging is performed by connecting the vehicle to a charging terminal, which is connected to a power source.

[0008] Therefore, like gas stations for gasoline vehicles, stations including a large number of charging terminals are being deployed everywhere to meet the growing demand of drivers.

[0009] Within the station, these terminals need to communicate with each other and / or with a station management center, which is, for example, an industrial computer or programmable logic controller installed locally at the station, in order to monitor the charging terminals locally and / or perform local energy management for the station.

[0010] As it stands, the terminals at a station are each connected by wire to a network switch, which itself is connected to a gateway (such as a modem) that provides Internet access. The terminals are also connected by wire to a local station management center.

[0011] This architecture involves numerous disadvantages. In fact, extensive wiring is required, and the architecture necessitates the installation of local control cabinets to house, inter alia, the network switches and internet gateways. Furthermore, the architecture requires network configuration using the Internet Protocol Suite (known as TCP / IP), which can prove costly and complex to implement. Furthermore, the architecture makes it difficult to add additional terminals to the station.

[0012] Furthermore, because this architecture is locally centralized, a single failure in a central node (especially a modem failure) can render the entire station unavailable.

[0013] Finally, the architecture involves a strong coupling between the software and providers of the charging terminals on the one hand and the management center on the other. Summary of the Invention

[0014] Therefore, the present invention aims to overcome the above-mentioned drawbacks and proposes a method for pairing a charging terminal with a network of stations having terminals, and an improved corresponding network.

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

[0016] - installing the charging terminal to be paired in a geographical area where the radius around a charging terminal of the network is less than the predefined maximum distance between two charging terminals of the network,

[0017] - supply energy to the charging terminal to be paired,

[0018] - activating a first operating mode on a first terminal of the network, the first mode remaining active for a predefined duration,

[0019] - if the network comprises other charging terminals, the first terminal of the network sends a command to activate the first operating mode to the other terminals of the network,

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

[0021] - a terminal of the network sends a signal regarding activation of the first operating mode,

[0022] - activating the first operating mode on the charging terminal to be paired while the first operating mode is activated on the first terminal of the network,

[0023] - pairing the terminal to be paired with a terminal of the network, the pairing being performed during activation of the first mode on all terminals of the network and the terminal to be paired.

[0024] Advantageously, the paired terminal is configured to detach from the network in the second operation mode.

[0025] Preferably, the pairing of the repeater with the network is the same as the pairing of the charging terminal.

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

[0027] Preferably, the activation signal is an acoustic signal or a light signal.

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

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

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

[0031] - define the initial configuration of energy management parameters,

[0032] - transmitting the initial configuration to all terminals of the station via the network,

[0033] - Each terminal of the network stores the initial configuration locally,

[0035] - determining a demand regarding power to be delivered from the first terminal,

[0036] - the first terminal obtains energy usage data from other terminals of the station via the network,

[0037] - determining the available power to be delivered by the first terminal based on the determined need for power to be delivered, the obtained energy usage data, and the defined initial configuration,

[0038] - determining a correction power to be delivered to be applied by each of the other terminals in the station that are delivering power based on the determined available power to be delivered by the first terminal, the retrieved energy usage data, and the defined initial configuration,

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

[0040] - the other terminals of the station apply the corrected power to be delivered which they have obtained,

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

[0042] - The first terminal charges the electric vehicle based on the determined available power to be delivered.

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

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

[0047] [ Figure 2 ] shows the method for connecting a charging terminal to a Figure 1 A method for network pairing of the terminal of the station;

[0048] [ Figure 3 ] presents a method for managing the energy delivered by a terminal of a station according to the invention. DETAILED DESCRIPTION

[0049] Figure 1 A charging station 1 for electric vehicles is schematically shown. The station 1 thus comprises one or more charging terminals 2 for electric vehicles, each of which is supplied with energy from an energy storage device 3 of the station 1 .

[0050] Charging terminal 2 according to Figure 2 The pairing method schematically shown in FIG is paired with each other so as to form a communication network 4. The pairing method will be described below by taking the pairing of a new terminal 2a that has not yet been paired with the network 4 as an illustrative example.

[0051] The terminal 2 a to be paired is the same as the terminal 2 that has already been paired and formed the network 4 , and therefore the following description of each terminal 2 of the network 4 applies to the terminal 2 a to be paired.

[0052] Each charging terminal 2 of the network 4 is configured to communicate with a remote object or server using telecommunication technologies.

[0053] In particular, each terminal 2 is configured to communicate with these remote objects or servers using medium-range wireless telecommunication techniques involving distances of the order of 10 to 20 meters.Preferably, the terminals 2 use the BLE telecommunication protocol, BLE standing for Bluetooth Low Energy.

[0054] Alternatively, the terminals 2 may also use the Bluetooth protocol. In other words, each terminal 2 is configured to communicate with a remote object that is at a medium distance and that is capable of communicating on the 2.4 GHz frequency band.

[0055] In particular, each charging terminal 2 is configured for medium-range communication with another similarly configured terminal 2. Thus, each charging terminal 2 is able to communicate with another charging terminal 2 using a common medium-range wireless telecommunication protocol (such as Bluetooth Low Energy or Bluetooth) covering a distance of the order of 10 to 20 meters.

[0056] Each terminal 2 is configured to operate in a first operating mode (referred to as pairing mode) and a second operating mode (referred to as unpairing mode).

[0057] More specifically, in a first operating mode, referred to as pairing mode, a terminal 2 can pair with another terminal 2 also operating in the first operating mode and / or with a network of terminal 2 in which terminals also operate in the first operating mode.

[0058] In other words, the terminal 2 that has been paired with the network 4 and is operating in the first mode can detect a new terminal 2 a that has not been paired with the network 4 and is also operating in the first operation mode, and can pair the new terminal 2 a with the network 4 .

[0059] Accordingly, a new terminal 2a that is not paired with the network 4 and is operating in the first operation mode can be paired with the network 4 having at least one terminal 2 operating in the first operation mode.

[0060] Therefore, the simultaneous activation of the first operating mode by two terminals 2 and 2a that have not yet been paired and are within a certain communication distance of each other will result in the pairing of the two terminals 2. Similarly, the simultaneous activation of the first operating mode by a terminal 2 of a network 4 and a terminal 2a that has not yet been paired with the network 4 will result in the pairing of the new terminal 2a with the network 4.

[0061] The first operating mode is activated by a switching device (eg a button) of the station 1 which is not accessible to the public.

[0062] When the switching device of terminal 2 is activated, terminal 2 begins to operate in the first operating mode. The first mode of terminal 2 is activated for a predefined duration starting from the activation of the switching device, so as to leave enough time to allow the first mode to be activated on one or more other terminals that are desired to be paired with the terminal 2.

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

[0064] When the predefined duration expires, the first operating mode is deactivated and the terminal 2 is no longer able to pair with and to the network.

[0065] In a second operating mode, referred to as unpairing mode, a terminal 2 that has been paired with a network 4 may be unpaired from the network 4, that is, a terminal 2 operating in the second operating mode is configured to separate from the terminal 2 and / or the network 4 with which it was previously paired.

[0066] Figure 2 The following schematically illustrates the steps of a method for pairing a new charging terminal 2a with a network 4 having at least one charging terminal 2. As described above, the new charging terminal 2a is substantially identical to the other terminals 2. In other words, the terminal 2a to be paired is configured to operate in a first operating mode (referred to as pairing mode) and a second operating mode (referred to as unpairing mode). Furthermore, the terminal 2a to be paired is also configured for medium-range communication with another identically configured terminal 2.

[0067] In a first step E1, the charging terminal 2a to be paired is installed in a geographical area defined by a predefined radius around a terminal 2 already paired with the network 4. If the terminal 2a is the first terminal to be paired, that is, if the network comprises only a single terminal 2, step E1 consists of installing the terminal 2a to be paired in a geographical area around the terminal 2.

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

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

[0070] During its installation, the terminal 2a is connected to the energy storage device 3 of the station 1 in order to supply energy to the terminal 2a.

[0071] Thus, in a second step E2 , the terminal 2 a is supplied with energy.

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

[0073] In a fourth step E4, the first terminal 2b operating in the first operating mode issues a command to activate the first mode to all other terminals 2 of the network 4. This activation command is transmitted to the other terminals 2 of the network 4 via the communication protocol used by the terminals 2 of the network 4 to communicate with each other.

[0074] In a fifth step E5 , the other terminals 2 of the network 4 receive the command to activate the first mode issued in step E4 and then change to operate in the first operating mode. Thus, the first operating mode is activated on all the terminals 2 of the network 4.

[0075] In a sixth step E6 , each terminal 2 of the network 4 sends a signal regarding the activation of the first operating mode, this signal being an optical and / or acoustic signal, in order to alert the technician that the network 4 is capable of pairing a new terminal 2 a to be paired.

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

[0077] Thus, in the final step E8, the terminal 2a to be paired is paired with the terminal 2 of the network 4. More specifically, pairing E8 is only performed if step E7 of activating the first mode of the terminal 2a to be paired is performed while the first mode of the first terminal 2b is active (that is, within the predefined duration after step E3). Indeed, if step E7 is performed after the predefined duration after the implementation of step E3, that is, if the first operating mode is activated on the terminal 2a to be paired after the predefined duration of activation of the first operating mode of the first terminal 2b has expired, the first terminal 2b is no longer operating in the first mode and is therefore unable to pair with the new terminal 2a to be paired.

[0078] Therefore, the terminal 2a to be paired with the network 4 must be paired during the activation of the first operating mode of the first terminal 2b.

[0079] This pairing is confirmed by, for example, the terminal 2a transmitting a pairing confirmation signal.

[0080] Thus, all paired terminals 2 of station 1 form a network 4 comprising terminals. Each terminal 2 of network 4 is therefore installed within the 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 is therefore able to communicate directly with one or more other terminals 2 of network 4 via a communication protocol commonly used by the terminals 2 of network 4.

[0081] Thus, all the terminals 2 of the station 1 form a wireless network 4 having a mesh topology, in which each terminal 2 constitutes a node of the network 4. Thus, communication between two terminals 2 of the network 4 occurs via a series of point-to-point links between adjacent terminals 2 of the network 4, with data packets being routed by each terminal 2, which autonomously and stepwise transmits the packets to the adjacent terminals 2.

[0082] Such a network therefore makes it possible to reduce wiring, makes it easier to add new terminals and is more resistant to the failure of one of the elements of the network.

[0083] If the terminal 2a to be paired must be installed in a location outside a geographical area with a predefined radius around one of the terminals 2, it is possible to use Figure 2 The same method pairs a repeater with a network at a given location so that the repeater is positioned within the range of terminal 2 a and within the range of another repeater of network 4 or one of the terminals 2 of network 4 .

[0084] Some terminals 2 of the network may include network access means for connecting to external networks, such as the Internet and / or remote servers. In this case, each terminal 2 of the network 4 can send and / or receive data from these external networks via the terminal 2 including the network access means. This Internet access can be used, in particular, for remote management and / or maintenance of the station 1.

[0085] Figure 2 The pairing method can also be used to pair a management and / or maintenance node with the network 4 , which node is formed, for example, by an industrial computer and / or a smartphone having the required authorization.

[0086] Furthermore, such a mesh network 4 facilitates maintenance, since information and / or configurations can be sent more reliably to all terminals 2 of the network 4 .

[0087] Have basis Figure 2 Such a network 4 of terminals 2 paired with one another according to the presented pairing method can be used in the context of a method for managing the energy delivered by one of the terminals 2 of a station 1 for charging an electric vehicle.

[0088] One of the challenges for a station that charges a terminal, such as station 1, is to manage its energy consumption locally.

[0089] In reality, there are numerous limitations that hinder the management of energy consumption and increase its magnitude. First, supplying energy is a costly process. Furthermore, the network power available at a station (e.g., station 1) (that is, the amount of power that the terminals 2 at station 1 can deliver simultaneously) is typically less than the sum of the power potentials of each of the terminals 2 at station 1 (that is, the sum of the power that can be delivered individually by each terminal 2 at station 1).

[0090] It will be recalled that power is the amount of energy per unit time. It is therefore known to use terms related to power and / or energy to describe the operation of charging a hybrid and / or electric vehicle.

[0091] Finally, local energy management is critical due to the complexity of storing and generating said energy.

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

[0093] More specifically, the initial configuration of the energy management parameters makes it possible to define a set of predefined rules and parameters organizing the energy management of the station 1 .

[0094] Thus, the initial configuration of the energy management parameters includes an energy access priority management protocol for the terminals 2 of the station 1 , and a definition of the type of power set point to be delivered by each terminal 2 of the station 1 .

[0095] The energy access priority management protocol for the terminals 2 of station 1 defines common priority management rules that the terminals 2 must follow in order to access energy. More specifically, one example of the rules to be followed might be energy priority allocation based on the temporal order of requests for energy supply from each terminal 2. Alternatively, the energy access priority management protocol for the terminals 2 might define arbitration based on data (such as the amount of energy each terminal 2 has delivered to a charged vehicle, or the amount of time each terminal 2 has spent charging its connected vehicle).

[0096] The access priority management protocol may also define terminals 2 that have priority access to energy.

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

[0098] The initial configuration of the energy management parameters is made locally in the station 1 (eg via a management node as defined above) or remotely (eg by means of a remote server and / or an internet server).

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

[0100] In a third step E11 , each terminal 2 of the network 4 of stations 1 stores the initial configuration locally in order to be able to apply it in the event of a vehicle connection.

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

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

[0103] The demand for power to be delivered is the ideal theoretical amount of power that the first terminal 2b should deliver after a vehicle is connected or disconnected.

[0104] Thus, if a vehicle is already connected, the power demand to be delivered is the ideal amount of power that the first terminal 2 b should deliver in order to optimize charging, regardless of the usage of the energy available from the station 1. Optimum charging of a vehicle is charging that is as efficient as possible, that is to say as fast as possible, depending on the technical characteristics of the terminal 2 and the vehicle already connected to it.

[0105] If, on the other hand, a vehicle has been disconnected from the terminal 2b, the demand regarding power to be delivered is essentially zero, since no vehicle is now connected to the first terminal 2b and the first terminal therefore no longer has to deliver any energy.

[0106] Therefore, the demand regarding the power to be delivered by the first terminal 2b depends on the technical characteristics of the vehicle that has been connected to the first terminal 2b (such as the maximum power and / or energy limit allowed when recharging the vehicle, the amount of energy and / or power required for recharging the vehicle), and the technical characteristics of the terminal 2b (such as the type of power setpoint to be delivered from 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 2 b to which the vehicle is connected or disconnected in step E13 obtains energy usage data from the other terminals 2 of the station 1 via the network 4 .

[0108] More specifically, the first terminal 2b sends a signal regarding connection or disconnection of the vehicle to the other terminals 2, to which these other terminals respond by sending their respective energy usage data to the first terminal.

[0109] The energy usage data of a terminal 2 of a station correspond to the amount of energy and / or power delivered by said terminal 2. These data are therefore negligible when no vehicle is connected to said terminal 2 and are equal to the amount of energy and / or power currently used to charge a vehicle when said vehicle is connected to said terminal 2.

[0110] In a seventh step E15 , the available power to be delivered by the first terminal 2 b to which the vehicle is connected or disconnected is determined.

[0111] The available power to be delivered is the maximum amount of power that the first terminal 2b is able to deliver to the vehicle in order to recharge it.

[0112] This item of available power to be delivered by the first terminal 2b is determined based on the energy usage data of each terminal 2 in the station received in step E14, the initial configuration of energy management parameters defined in step E9 and stored locally by the first terminal 2b, and the demand for power to be delivered by the first terminal 2b determined in step E13.

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

[0114] If step E12 corresponds to the connection of a vehicle to the first terminal 2 b and the energy storage means of the station 1 allow it, the available power to be delivered by the first terminal 2 b is set to the level of the power demand to be delivered determined in step E13. Otherwise, the available power to be delivered is set to a lower level.

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

[0116] In the following step E16, a correction power item to be delivered is determined for each of the other terminals 2 of the station 1. More specifically, a correction power item to be delivered is determined for each of the other terminals 2 of the station 1 that are currently delivering energy (that is, connected to a vehicle), with terminals that are not connected to a vehicle essentially not delivering energy.

[0117] The correction power to be delivered by the terminal 2 that is delivering power is determined based on the power available to the first terminal 2 b , the energy usage data of each terminal 2 obtained in step E14 , and the defined initial configuration.

[0118] The correction power to be delivered by the terminal 2 that is delivering power is preferably determined by the first terminal 2 b in order to reduce communications within the network 4 .

[0119] More specifically, for each terminal 2 that delivers energy, the first terminal 2b determines the corrective power to be delivered based on: the energy that can be delivered to the vehicle, which is limited by the available power to be delivered by the first terminal 2b; the energy initially delivered by the terminals 2, which is limited by the energy usage data of these terminals 2; and the initial configuration, and in particular the energy access priority management protocol.

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

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

[0122] Finally, in a final step E20 , the first terminal 2 b , having received confirmation of the application of the corrective power term to be delivered from each of the other terminals 2 of the station 1 , charges the vehicle based on the available power to be delivered determined in step E15 .

[0123] Therefore, each time a vehicle is connected or disconnected from one of the terminals of station 1, the Figure 3 This method thus allows an improved energy management of the station 1 , since it is decentralized. In fact, in this method it is not necessary to have a central energy management center, the management being performed directly by each terminal of the station 1 via the network 4 .
