Description

Title of the invention: Method for authenticating a mobile object by an electric vehicle charging station and associated methods for charging an electric vehicle and for communicating a charging station with a remote server. technical field

[0001] The invention relates, in general, to the charging of an electric vehicle in a station with one or more electric vehicle charging points.

[0002] The invention relates more specifically to the arrival phase of an electric vehicle in such a public station, or at least one physically accessible to unauthorized vehicles.

[0003] The invention relates more particularly to a method for authenticating a mobile object associated with an electric vehicle for the purpose of charging said electric vehicle. Prior 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 with one or more electric charging points are being deployed in territories to meet the growing needs of motorists.

[0009] However, since the time required to recharge an electric car can reach several tens of minutes, some of these stations adopt an operation whereby only authenticated users can use a terminal of said station to recharge their electric or hybrid vehicle.

[0010] Authenticating users who have the right to use the station due to a subscription or any other discriminatory method also constitutes a lever for saving time at the entrance to charging stations.

[0011] Indeed, stations may not have physical obstacles to accessing a terminal, so an unauthenticated user may sometimes clog the station and slow down traffic.

[0012] The objective of user authentication is therefore to streamline traffic at within the station and a time saving for users.

[0013] Several methods of user authentication exist.

[0014] A first existing method is authentication via a badge placed by the user on a badge reader, generally located on the charging station, to allow authentication of the badge owner. The badge and reader typically use very short-range communication techniques such as NFC (Near-Field Communication) or RFID (Radio-Frequency Identification).

[0015] A second existing method is authentication via a smartphone application or a web page, whereby the user wishing to be authenticated identifies himself by actions on his phone upon arrival at the station, a remote server authorizing the authentication of the user at the station.

[0016] These existing solutions have the major drawback of requiring repetitive actions on the part of the user each time they arrive at the station, or even at the start of each charge, whether it is on the one hand getting out of the vehicle to place the badge against the reader, or on the other hand manipulating their phone.

[0017] A reliability problem also arises, as these solutions require a 4G, 5G or other connection in order to exchange requests with remote servers, which may be rare in rural areas.

[0018] Finally, these solutions are expensive.

[0019] Another solution, called by the Anglo-Saxon expression "Plug & charge", requires plugging the vehicle into the terminal to authenticate the user.

[0020] The present invention therefore aims to overcome the aforementioned drawbacks and to propose an authentication method that does not require any intervention from the user upon arrival at the station.

[0021] The present invention thus relates to a method for authenticating a mobile object by an electric vehicle charging station to enable the charging of an electric vehicle, the station being part of a station of one or more charging stations, the mobile object being associated with the electric vehicle and with a user account linked to a user of the electric vehicle, comprising the following steps:

[0022] - Penetration of the moving object into a geographical area delimited by a radius predefined around the charging station,

[0023] - Automatic establishment of communication between the mobile object and the terminal recharge,

[0024] - Retrieval of vehicle charging information by the charging station electric,

[0025] - Verification of the accounting of at least one of the terminals of the station and the electric vehicle based on the charging information retrieved.

[0026] Advantageously, the mobile object is integrated into the vehicle or transportable by the vehicle user.

[0027] Advantageously, the mobile object is a driver's phone, a portable smart beacon, or a vehicle module.

[0028] Preferably, communication between the mobile object and the charging station uses a medium-range wireless communication protocol.

[0029] Advantageously, the protocol is the BLE or Bluetooth protocol.

[0030] Preferably, the user account includes the electric vehicle charging information.

[0031] Advantageously, the vehicle charging information includes a type of vehicle charging interface, the existence of a valid means of payment, and a maximum power allowed for charging by the electric vehicle.

[0032] Preferably, the automatic communication establishment step comprises the following sub-steps:

[0033] - Periodic transmission of a communication initialization frame by the object mobile,

[0034] - Reception of the frame by one or more charging stations,

[0035] - Establishing communication between the mobile object and the nearest terminal of the moving object.

[0036] Advantageously, the step of verifying the compatibility of at least one of the terminals and the vehicle includes the following sub-steps:

[0037] - Verification of authorization to use the station,

[0038] - Verification that the power delivered by the charging station is compatible with the vehicle,

[0039] The invention also relates to a method for recharging an electric vehicle associated with a mobile object at a charging station forming part of a station with one or more terminals, the mobile object also being associated with a user account linked to a user of the electric vehicle, the method comprising the following steps:

[0040] - Authentication of the mobile object by a first terminal of the station according to the process as defined previously,

[0041] - Selection of the most suitable charging station for the electric vehicle,

[0042] - Emission of a signal authorizing the connection of the vehicle to the selected terminal and / or on the moving object,

[0043] - Connecting the vehicle to the selected charging station,

[0044] - Vehicle charging.

[0045] In one embodiment, the charging method includes an optional step of reserving a charging station prior to the step of authenticating the mobile object by the first marker.

[0046] Advantageously, the connection authorization signal is an audible and / or visual signal and / or the removal of a barrier blocking access to the chosen charging station.

[0047] Preferably, the step of selecting the most suitable charging station for charging the electric vehicle comprises the following steps:

[0048] - Retrieval by the first terminal of the charging conditions of the others station terminals,

[0049] - Retrieval by the first terminal of information concerning the availability of other terminals of the station,

[0050] - Selection by the first terminal of a suitable terminal from among the terminals of the station, the election depending on information regarding availability and recharging conditions retrieved in previous steps,

[0051] - Transmission by the first terminal of identification data of the elected terminal to the moving object.

[0052] The invention also relates to a method of communication between a charging station of one or more charging stations and one or more data servers, the communication being established via a mobile object connected to the internet and configured to exchange with the remote server(s), the method comprising the following steps:

[0053] - Authentication of the mobile object by the charging station according to a process authentication as defined previously,

[0054] - Emission by the charging station towards the mobile object of a first packet of data for a confirmation request for established communication and a second data packet of requests to be executed by the remote server(s),

[0055] - Transmission by the mobile object of the first and second emitted data packets to the remote server(s),

[0056] - Reception by the mobile object of a third confirmation data packet communication established and a fourth result packet of the queries from the second packet executed.

[0057] Advantageously, communications between the terminal and the servers are secured using public key infrastructures. Brief description of the drawings

[0058] 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:

[0059] [Fig.l] schematically illustrates an electric vehicle arriving at a charging station;

[0060] [Fig.2] illustrates an authentication method according to the invention;

[0061] [Fig.3] illustrates a method of charging an electric vehicle according to the invention;

[0062] [Fig.4] illustrates a method of communication between a charging station and a or several remote servers according to the invention. Detailed description of at least one embodiment

[0063] 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.

[0064] Fig. 1 also illustrates a user 3 of station 1. User 3 is, for example, the driver of an electric or hybrid vehicle 4 equipped with a plug-in on one of the terminals 2. User 3 may also simply be the owner of the vehicle 4, or even a passenger.

[0065] Fig. 2 schematically illustrates the steps of a process for authenticating a mobile object 5 by one of the charging stations 2, prior to charging the vehicle 4.

[0066] The mobile object 5 is associated with the vehicle 4 and with the user 3. More specifically, the mobile object 5 is associated with the vehicle 4 and with a user account in the name of the user 3. The user account is, for example, created on the internet by the user 3, and includes a certain amount of information relating to the user 3, the mobile object 5 and / or the vehicle 4.

[0067] The mobile object 5 is integrated into the vehicle 4, or transportable by the user 3. More particularly, in the case illustrated in [Fig. 1], the mobile object 5 is a module of the vehicle 4. Alternatively, the mobile object 5 can be the vehicle 4 itself, a smart portable beacon, for example attached to the key ring of the user 3, or even the user 3's smartphone. Ideally, the mobile object 5 is therefore an object necessarily present with the vehicle 4 upon arrival at the station 1.

[0068] The mobile object 5 includes a communication module 5a configured to communicate by telecommunications techniques with remote objects or servers.

[0069] In particular, the communication module 5a of the mobile object 5 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 communication module 5a uses the BLE telecommunications protocol, an acronym for Bluetooth Low Energy.

[0070] Alternatively, the communication module 5a can also use the Bluetooth protocol. In other words, the mobile object 5 is configured to communicate with the remote objects located at medium distance and capable of communicating on the 2.4 GHz frequency band.

[0071] The charging stations 2 are also configured to communicate over medium distances with remote objects such as the mobile object 5, in particular to authenticate the mobile object 5. Each charging station 2 is therefore capable of communicating with the mobile object 5 via a common medium-range wireless telecommunication protocol, on the order of 10 to 20 meters, such as Bluetooth Low Energy or Bluetooth.

[0072] The steps of the process of authenticating the mobile object 5 by one of the charging stations 2 illustrated in [Fig.2] are described below.

[0073] In a first step El, the mobile object 5 enters a geographical area delimited by a predefined radius around one of the charging stations 2.

[0074] In other words, the mobile object 5 enters a geographical area comprising at least one charging station 2 capable of authenticating it.

[0075] The predefined radius delimiting the geographical area is defined by the maximum distance allowed by the telecommunications protocol used jointly by the mobile object 5 and the charging station 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.

[0076] In other words, in step El, the mobile object 5 approaches a charging station 2 of station 1 sufficiently to establish wireless communication with said charging station 2.

[0077] In a second step E2, communication is automatically established between the mobile object 5 and one of the charging stations 2 located in said geographical area.

[0078] Step E2 comprises several sub-steps described below.

[0079] In a first sub-step E21, the mobile object 5 periodically transmits a communication initialization frame. This frame has no specific recipient and simply constitutes a discovery frame allowing the mobile object 5 to signal itself to the terminals 2 capable of receiving said frame, i.e., those located within range of the mobile object 5.

[0080] The communication initialization frame is thus emitted by the mobile object 5 in all directions around it by the medium-range wireless communication protocol.

[0081] After the transmission of a communication initialization frame by the mobile object 5, the mobile object 5 waits for a predefined period to possibly detect one or more responses to this frame. The predefined period is between 2 and 10 seconds, and is, for example, 5 seconds. Upon expiration of the predefined period following the transmission of a communication initialization frame, the mobile object 5 transmits a new communication initialization frame.

[0082] As long as no response to a communication initialization frame is received by the mobile object 5 that sent it, the mobile object 5 continues to periodically send other communication initialization frames, the transmissions of two successive frames being separated by the predefined duration.

[0083] In a second sub-step E22, a communication initialization frame is received by one or more charging stations 2. In fact, the mobile object 5 transmitting the frame received by the station or stations 2 is thus located in the geographical area defined in step El around each of said stations 2 having received the frame.

[0084] In a third sub-step E23, communication is established between the mobile object 5 and one of the terminals 2 which received the communication initialization frame.

[0085] More specifically, each of the terminals 2 that received the transmitted frame individually generates a response to said frame in order to establish communication with the mobile object 5, and then transmits this generated response. The mobile object 5 receives all the generated responses from each of the terminals 2 that received the communication initiation frame, and selects one of the terminals to establish communication with it.

[0086] In practice, communication is established between the mobile object 5 and the nearest terminal 2. For example, communication is established between the mobile object 5 and the terminal 2 that received the communication initiation frame with the best RSSI. RSSI, an acronym for "Received Signal Strength Indication," is the known measure of the strength of a signal received by a telecommunications receiver.

[0087] Communication between the mobile object 5 and one of the terminals 2 is therefore established automatically in that no intervention from the user 3 is necessary, the establishment of communication being automatic as soon as the mobile object 5 enters the geographical area defined around one of the terminals 2.

[0088] In a third step E3, the terminal 2 communicating with the mobile object 5 retrieves charging information from the vehicle 4 via the mobile object 5.

[0089] The mobile object 5, as described above, is associated with a user account in the name of user 3 and vehicle 4. The user account includes various charging information relating to vehicle 4 and user 3, enabling the charging station 2 to authenticate the mobile object 5, so as, for example, to allow the charging of vehicle 4, once authentication has been carried out.

[0090] The charging information relating to vehicle 4 includes, for example, a type of charging interface accepted by vehicle 4. For example, the type The charging interface accepted by vehicle 4 can be a DC direct current charging interface and / or an AC alternating current charging interface.

[0091] The charging information relating to vehicle 4 also includes a maximum and / or minimum limit of power and / or energy permitted for charging by vehicle 4.

[0092] 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 such as vehicle 4 using terms relating to power and / or energy.

[0093] The top-up information relating to user 3 includes, for example, the existence and validity of a means of payment.

[0094] The charging information may also include reservation information for a terminal 2 of station 1, or any other information relating to the user 3, the vehicle 4, or the mobile object 5.

[0095] Once the charging information has been retrieved by the charging station 2 in communication with the mobile object 5, said station 2 performs in a final step E4 a check of the compatibility of at least one of the stations 2 of station 1 with the vehicle 4, according to the charging information retrieved.

[0096] Step E4 comprises several sub-steps described below.

[0097] In a first sub-step E41, the terminal 2 in communication with the mobile object 5 first checks an authorization to use the station 1 by the mobile object 5, and more generally by the user 3 and the vehicle 4 associated with the mobile object 5.

[0098] More specifically, verifying authorization to use station 1 consists in particular of verifying that user 1 is authorized to use station 1. For example, this verification depends on the existence of a valid payment method for user 3 stored in the user account associated with the mobile object 5. Verification E41 may also include verifying that the vehicle associated with the mobile object 5 is indeed vehicle 4, or that user 3 is authorized to use station 1 within a time frame corresponding to the entry of the mobile object 5 into station 1. This verification E41 is performed by the terminal 2 in communication with the mobile object 5 based on the charging information retrieved by said terminal 2 from the user account associated with the mobile object 5.

[0099] In a second sub-step E42, the terminal 2 in communication with the mobile object 5 checks a compatibility between the vehicle 4 and at least one of the terminals 2 of the station 1.

[0100] To this end, the terminal 2, in communication with the mobile object 5, uses the charging information retrieved in step E3, and verifies that elements such as the type of charging interface accepted by the vehicle 4, the maximum power and / or energy limits supported by the vehicle 4 for its charging, or any other information training relating to the compatibility of vehicle 4 with a charging station, are all capable of being respected by at least one of the terminals 2 of station 1. In other words, terminal 2 in communication with the mobile object 5 checks in substep E42 that at least one of the terminals 2 of station 1 is configured to charge vehicle 4, that is to say that it includes the technical characteristics necessary to satisfy in particular the type of charging interface accepted by vehicle 4, and / or to not exceed the maximum and / or minimum limits of energy supply and / or power to vehicle 4.

[0101] The exchanges between the mobile object 5 and the terminal 2 can be signed and authenticated via a public key infrastructure. Optionally, the certificates containing the private and / or public keys necessary for communications between the mobile object 5 and the terminal 2 can be stored locally on the mobile object 5 before arriving at the station 1. In this way, no internet connection is required at the station 1 for authentication.

[0102] If the user 3 associated with the mobile object 5 is authorized to use the station 1, and at least one of the charging points 2 of the station 1 is compatible with the vehicle 4, then the mobile object 5 is authenticated in a step E5. Otherwise, the authentication fails.

[0103] The described authentication process illustrated in [Fig.2] is usable in the context of a vehicle charging process 4, this charging process being schematically illustrated in [Fig.3].

[0104] The steps of the process illustrated in [Fig.3] of recharging the vehicle 4 associated with the mobile object 5 on one of the charging terminals 2 of the station 1 are described below.

[0105] The charging process initially includes an optional first step E0 of reserving a charging point 2 at station 1. This step can be carried out by the user 3, even before arriving at station 1 and authenticating themselves, for example via the mobile device 5 and / or via their user account associated with the mobile device 5. This optional step E0 can be carried out, for example, using an online schedule for the use of the charging points 2 at station 1. Preferably, the online schedule only allows the user 3 to reserve a charging point suitable for the vehicle 4 associated with the mobile device 5 and the user account, through a process similar to step E4 based on the information available on the user account.

[0106] In a subsequent step E6 of the charging process, the mobile object authentication process illustrated in [Fig.2] is implemented, so that the mobile object 5 associated with the vehicle 4 and the user account linked to user 3 is authenticated by a first terminal 2a of the terminals 2 of station 1.

[0107] In a second step E7, the first terminal 2a in communication with the mobile object 5 during the implementation of the authentication step El elects the most suitable terminal 2 among the terminals 2 of station 1 to recharge the vehicle 4 associated with the mobile object 5.

[0108] This election step E7 comprises several substeps described below.

[0109] In a first substep E71, the first terminal 2a retrieves charging conditions from the other terminals 2 of the station 1. These conditions include the characteristics and technical parameters of each terminal 2 of the station for charging an electric or hybrid vehicle, such as the type of charging interface offered by the terminal (AC alternating and / or DC continuous), the maximum and / or minimum limits of power and / or energy delivery, etc.

[0110] In a second substep E72, the first terminal 2a retrieves information concerning the availability of the other terminals 2 of the station 1. For example, the information concerning the availability of the other terminals 2 includes charging status data relating to each terminal 2 of the station translating whether said terminal 2 is charging a vehicle or not.

[0111] In an optional third substep E73, the first terminal 2a retrieves information concerning the availability of power and / or energy to be delivered by station 1. This availability is a quantity of energy and / or power that can be delivered by the available terminals 2 of the station, depending, for example, on the energy reserves of station 1, the quantity of energy and / or power being delivered by the terminals 2 charging a vehicle, the constraints of the electrical network of station 1, etc. For example, the first terminal 2a retrieves this information concerning the availability of power and / or energy to be delivered by station 1 in a station 1 management means, for example consisting of a central industrial computer capable of communicating with each of the terminals 2 of station 1.

[0112] In an optional fourth substep E74, the first terminal 2a retrieves information relating to the charging needs of vehicle 4 and user 3. This information is available, for example, on the user account associated with the mobile object 5 and includes, for example, the amount of energy required by vehicle 4 and / or a charging time constraint for vehicle 4. This information can, for example, be optionally configured by user 3 on the associated user account, according to their desired use of vehicle 4. For example, the amount of energy required by the vehicle may default to the amount of energy needed to fully charge the batteries of vehicle 4, and user 3 may modify this amount of energy on their user account so that it is equal, for example, to the amount of energy needed to complete their journey with vehicle 4.Similarly, for example, the default duration constraint can be . null, and user 3 can modify it on their user account according to the time they wish to spend recharging their vehicle 4 at station 1.

[0113] In a fifth substep E75, the first terminal 2a selects the most suitable terminal 2 from among the terminals 2 of the station. This selection depends on the charging information of vehicle 4 retrieved during the implementation E6 of the authentication process, the charging conditions of the terminals 2 retrieved in substep E71, information concerning the availability of the terminals 2 retrieved in substep E72, and, where applicable, information concerning the availability of power and / or energy to be delivered by station 1 retrieved in substep E73, and information relating to the charging needs of vehicle 4 and user 3 retrieved in substep E74. During this selection step E75, the first terminal 2a implements a decision algorithm based on the various pieces of information retrieved. The algorithm then selects a suitable terminal 2b from among the terminals of station 1.

[0114] In a final substep E76, the first terminal 2a transmits identification data of the selected suitable terminal 2b to the mobile object 5. For example, the identification data is a terminal number or an audible and / or visual signal indicating to the user 3 the selected terminal 2b.

[0115] Following step E7 of selecting the suitable charging station 2b, a signal authorizing the connection of vehicle 4 to the suitable charging station 2b is emitted in step E8. This signal may be audible and / or visual, and is emitted when vehicle 4 approaches the location of the suitable charging station 2b. Possibly, a barrier blocking access to said suitable charging station 2b is removed simultaneously, for example via wireless communication.

[0116] In a step E9, vehicle 4 is then connected to the suitable terminal 2b, and the charging of vehicle 4 takes place (step E10).

[0117] The described authentication method illustrated in [Fig.2] can also be used in the context of a communication method between one of the terminals 2 of station 1 and one or more remote data servers, illustrated in [Fig.4].

[0118] Indeed, it sometimes happens that terminals 2 of the station are not equipped with a means of network access allowing connection to remote external networks or servers, such as the Internet.

[0119] The method of [Fig.4] allows terminals 2 of station 1 to perform bidirectional exchanges with such external networks via the mobile object 5, this mobile object 5 having such a means of network access.

[0120] The mobile object 5 is therefore, for example, connected to the Internet, and is configured to connect to remote servers of station 1, such as monitoring and / or maintenance and / or management servers of station 1.

[0121] In a first step El 1 of the process, the process for authenticating the mobile object 5 illustrated in [Fig.2] is implemented, so that the mobile object 5 associated with the vehicle 4 and the user account linked to the user 3 is authenticated by the first terminal 2a of the terminals 2 of the station 1.

[0122] In a second step El2, a first data packet requesting confirmation of established communication and a second data packet of requests to be made by one or more targeted remote servers and / or networks are both generated and sent by the charging station 2a which has authenticated the mobile object 5 to the mobile object 5.

[0123] In a third step E13, the mobile object 5 receives the two data packets and transmits them to the targeted remote servers and / or networks. Indeed, the mobile object 5, which includes a means of accessing these servers and / or networks, can transmit the packets generated by the terminal 2a in the same way as if it had generated them itself. The mobile object 5 thus forms a gateway between the terminal 2a and the remote servers and / or networks such as Internet.

[0124] In a fourth step El4, the two packets are processed by the target servers and / or networks. More specifically, the target servers and / or networks receive the two packets and formulate a response to each.

[0125] Thus, the targeted servers and / or networks generate a third communication confirmation packet in response to the first packet, perform the requests of the second packet, and generate a fourth result packet of the requests of the second packet executed.

[0126] In a fifth step E15, the mobile object 5 receives the third and fourth packets, and transmits them to terminal 2a.

[0127] In the communication method of [Fig.4], communications between terminal 2a and remote servers and / or networks are advantageously secured using public key infrastructures.

[0128] The method therefore allows, by repeating its implementation as often as necessary, a connection between a terminal 2a of station 1 and remote networks and / or servers such as the Internet.
