Description

Title of the invention: Method and device for controlling a reservation system for an electric vehicle charging station. Technical field

[0001] The present invention relates to methods and devices for controlling a system for reserving a charging station for an electric vehicle, in particular a motor vehicle. The present invention also relates to methods and devices for selecting an electrical energy charging station compatible with an electric vehicle. Technological background

[0002] To plan a journey to be made with a vehicle, it is known to use a navigation system, such a system being for example embedded in a vehicle or implemented in a mobile device, for example a mobile telephone, itself embedded in the vehicle. Such a system uses map data such as digital road maps indicating the different road routes that the vehicle can take to go from point A to point B.

[0003] These map data are for example used to offer a driver the shortest, fastest, most economical route or the one that does not take a fast lane, etc. They can also be used by certain functions or driving assistance systems, called AD AS (from the English “Advanced Driver-Assistance System” or in French “Advanced Driving Assistance System”), to guide or control the vehicle in its environment to reach its destination.

[0004] Information on current traffic conditions, map updates, or weather conditions is used in particular to plan a route. Access to this information is sometimes the subject of a service provided by a service provider, for example the vehicle manufacturer or the manufacturer of the navigation system. A user has, for example, access to this information on current traffic conditions, map updates, or weather conditions via a subscription to this type of service. This is referred to as information from a connected service. The navigation system uses this information to calculate a route or announce an event on a calculated journey.

[0005] Electric vehicles must in particular be supplied with electrical energy along a route, for example at a charging station located along a route planned by a navigation system. It is important, before going to such a charging station, to know the technical characteristics and services proposed to ensure that the station is compatible with the electric vehicle and its charging mode(s).

[0006] Electric vehicles also benefit from various charging techniques, frequently called “charging modes”. Thus, certain electric vehicles can be recharged from a domestic power outlet or from a charging station using one or more of the following methods: - mode 1 corresponds to recharging carried out via a normal power outlet (220 V, max 10 A) without limitation and without protection, - mode 2 corresponds to recharging carried out from a conventional domestic socket with earthing, to which a charging cable is connected, often supplied with the electric vehicle, which connects the domestic socket to the electric car and is equipped with a current limiter, - mode 3 corresponds to recharging with a dedicated charger allowing recharging to be controlled, in particular by communicating with the electric vehicle in order to adapt the power delivered to the needs of the electric vehicle, and - mode 4 corresponds to rapid recharges and uses direct current.

[0007] A cable used to connect a charging station and the electric vehicle must then be adapted to both the charger of the charging station and the electric vehicle. Summary of the present invention

[0008] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0009] Another object of the present invention is to facilitate the recharging of electric vehicles.

[0010] Another object of the present invention is to control a reservation system for an electric vehicle charging station.

[0011] According to a first aspect, the present invention relates to a method for controlling a reservation system for an electric vehicle charging station, the method comprising the following steps: - reception of initial data representative of a geographical position of the electric vehicle; - determination of a set of electrical energy charging stations based on geographical position; - selection via a human-machine interface of an electrical energy charging terminal from the set of electrical energy charging terminals based on information representative of a type of cable available at the electrical energy charging terminal; - transmission of second data representative of a request to reserve the charging station via a wireless connection.

[0012] Such a method makes it possible to ensure the availability of a charging cable compatible with the electric vehicle. A user is then certain to find at the selected and reserved charging station the means adapted to the electrical energy charging of his electric vehicle.

[0013] According to a variant of the method, the type of cable corresponds to a cable configured to ensure communication of charging data between the electric vehicle and the charging station.

[0014] According to another variant of the method, the cable type is configured for mode 3 charging.

[0015] According to an additional variant of the method, each of the electrical energy charging terminals of the set of electrical energy charging terminals is located at a distance from the electric vehicle less than a threshold.

[0016] According to another variant of the method, the information representative of the type of cable is received from a remote server.

[0017] According to yet another variant of the method, the second data comprises data representative of a date and a time.

[0018] According to another variant, the method further comprises steps of - display control for the electrical energy charging station of information representing the type of cable on a screen; - reception of third data representative of a touch press on a graphic object representative of a command to reserve the electric energy charging station, the graphic object being displayed on the screen, the transmission being triggered by the reception of the third data.

[0019] According to a second aspect, the present invention relates to a device for controlling a reservation system for a charging station for an electric vehicle, the device comprising a memory associated with a processor configured for implementing the steps of the method according to the first aspect of the present invention.

[0020] According to a third aspect, the present invention relates to an electric vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.

[0021] According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for executing the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0022] Such a computer program may use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0023] According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the method according to the first aspect of the present invention.

[0024] On the one hand, the recording medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or a magnetic recording means or a hard disk.

[0025] Furthermore, this recording medium may also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or hertzian radio or by self-directed laser beam or by other means. The computer program according to the present invention may in particular be downloaded from an Internet-type network.

[0026] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to perform or to be used in performing the method in question. Brief description of the figures

[0033] A method and a device for controlling a system for reserving a charging station for an electric vehicle will now be described in the following with joint reference to Figures 1 to 5. The same elements are identified with of the same reference signs throughout the description which follows.

[0034] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to enable different elements (such as operations, means, etc.) implemented in the embodiments described below to be identified and distinguished. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0035] According to a particular and non-limiting example of embodiment of the present invention, the control of a reservation system for a charging station for an electric vehicle is for example implemented by one or more processors of an on-board system of the electric vehicle or of a mobile communication device.

[0036] For this purpose, the method comprises receiving first data representative of a geographical position of the electric vehicle and determining a set of electrical energy charging stations as a function of the geographical position of the electric vehicle.

[0037] An electrical energy charging terminal is then selected via a human-machine interface from the set of electrical energy charging terminals based on information representative of a type of cable available at the electrical energy charging terminal.

[0038] Second data representative of a request to reserve the charging station are then transmitted via a wireless connection.

[0039] [Fig.l] schematically illustrates an electric vehicle and its communication environment, according to a particular and non-limiting exemplary embodiment of the present invention.

[0040] [Fig.l] illustrates an electric vehicle 10, for example a motor vehicle, in a communication environment 1, the electric vehicle 10 being for example in a road environment or on a parking area or parking lot, in a garage, etc. According to other examples, the electric vehicle 10 corresponds to a coach, a bus, a truck, a utility vehicle or a motorcycle, that is to say to a vehicle of the motorized land vehicle type.

[0041] The electric vehicle 10 corresponds for example to a vehicle with electric motor(s).

[0042] The electric vehicle 10 advantageously carries a communication system configured to communicate with one or more remote devices or servers 111 via a wireless communication network infrastructure.

[0043] The electric vehicle communication system 10 is also configured to communicate with one or more mobile communication devices 11 in direct communication mode and / or via the wireless communication network infrastructure. The mobile communication device 11 corresponds by example to a smartphone, a tablet or even a connected mobile object such as a connected watch, also called a smart watch (from the English “Smartwatch”).

[0044] A direct wireless communication mode is based, for example, on one of the following communication standards or protocols: - Wifi® according to IEEE 802.11, for example according to IEEE 802.1 In or IEEE 802.1 lac, for example according to a communication mode called infrastructure according to which the electric vehicle 10 acts as an access point according to an ad-hoc or direct communication mode, called Wifi Direct; - Bluetooth®; - ZigBee according to IEEE 802.15.4.

[0045] The electric vehicle 10 and / or the mobile communication device 11 are further configured to communicate with one or more remote servers 111, for example via the wireless communication network infrastructure.

[0046] The remote server(s) 111 each correspond, for example, to a server of the “cloud” 100 (or “cloud” in French). The wireless communication infrastructure comprises, for example, a set of communication devices of the cellular network antenna type 110 of the LTE (Long Term Evolution) 4G or 5G type.

[0047] The communication system of the electric vehicle 10 comprises, for example, one or more communication antennas connected to a telematic control unit, called TCU (from the English “Telematic Control Unit”), itself connected to one or more computers of the on-board system of the electric vehicle 10. The antenna(s), the TCU unit and the computer(s) form, for example, a multiplexed architecture for the realization of different services useful for the proper functioning of the vehicle and for assisting the driver and / or the passengers of the vehicle in the control of the electric vehicle 10.The computer(s) and the TCU communicate and exchange data with each other via one or more computer buses, for example a communication bus of the CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to the ISO 17458 standard) or Ethernet (according to the ISO / IEC 802-3 standard) data bus type.

[0048] The electric vehicle 10 has a navigation and geolocation system, also called a GNSS system (Geolocation and Navigation by a Satellite System), for example a GPS type system (from the English “Global Positioning System” or in French “Geo-positioning system by satellites”).

[0049] The electric vehicle 10 is, in addition, advantageously connected in wireless communication wire with a remote device such as the remote server 111 via the “cloud” 100, such a remote device being for example configured to communicate with the electric vehicle 10 according to an OTA type connection.

[0050] The remote server 111 is for example configured to send data relating to a set of electrical energy charging stations or terminals and for each electrical energy charging terminal data belonging to a set of particular data representative of: - an identifier, - an address or geographic position, - a type of cable available, - an operator or service provider, - opening hours, - a type of access, - a type of payment method, - a delivered power, - a charging mode, - prices, - time slots available for booking, and - an alert or a message.

[0051] As illustrated in [Fig.2], the electric vehicle 10 incorporates, for example, in its passenger compartment, a display system comprising a screen 102 and a computer configured to control the display of content(s) of a human-machine interface, called graphic HMI on the screen 102. The computer corresponds for example to the computer of the infotainment system, called IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement embargo”) of the vehicle.

[0052] The screen 102 is for example touch-sensitive and corresponds for example to a screen of the LCD type (from the English “Liquid Crystal Display” or in French “Display à cristals liquide”), for example of the TFT type (from the English “Thin-Film Transistor” or in French “Transistor en film mince”), or OLED type (from the English “Organic Light-Emitting Diode” or in French “Diode électroluminescente biologique”). The screen 102 is for example arranged in the center of the dashboard 101, for example above a central facade. Of course, the position of the screen 102 is not limited to this example, the screen being able to be arranged in any position, for example on the central facade.

[0053] The screen 102 allows content to be displayed to the driver and passengers of the vehicle. The screen 102 is also configured to allow the driver and / or passengers of the vehicle to interact with one or more systems embedded in the vehicle via a human machine interface (HMI) displayed on the screen 102. For example, the screen makes it possible to control the IVI system or a navigation system on board the electric vehicle 10.

[0054] According to another example, as illustrated in [Fig.l], the screen 102 is not integrated into the passenger compartment but corresponds to a screen 102 of the mobile communication device 11, such as a smartphone or a tablet, connected in communication, for example wirelessly, with the on-board system of the electric vehicle 10.

[0055] A process for controlling a system for reserving a charging station for the vehicle 10 is advantageously implemented by one or more processors of the navigation system, for example by a computer of an on-board system of the vehicle 10 or by a processor of the mobile communication device 11.

[0056] In a first operation, first data representative of a geographical position of the electric vehicle 10 are received, for example by the computer.

[0057] According to a particular exemplary embodiment, the first data are received from the navigation system of the electric vehicle 10. They then make it possible to position the electric vehicle 10 on a road map or a plan, for example, determined using geolocation coordinates of the electric vehicle 10, the navigation system comprising, for example, a map.

[0058] In a second operation, a set of electrical energy charging stations is determined based on the geographical position of the electric vehicle 10.

[0059] The geographical positions of the electrical energy charging stations are for example recorded in the map of the navigation system, or for example received from a remote server 111.

[0060] This set of electrical energy charging terminals is for example determined as a function of the distance separating each of the electrical energy charging terminals of this set from the electric vehicle 10, for example, each of the electrical energy charging terminals of this set is located at a distance from the electric vehicle 10 less than a threshold.

[0061] According to a particular embodiment, this threshold is defined as being equal to 5km, 10km or 30km.

[0062] According to another particular exemplary embodiment, this threshold is defined as a function of a range of the electric vehicle 10 determined, for example, from a charge level of a traction battery of the electric vehicle 10. Thus, according to this particular exemplary embodiment, the set of electrical energy charging terminals corresponds to the electrical energy charging stations accessible for the electric vehicle 10.

[0063] According to another particular embodiment, the set of electrical energy charging terminals is for example determined as a function of the distance separating each of the electrical energy charging terminals at a point on a route determined by the navigation system of the electric vehicle 10. This set of electrical energy charging terminals thus corresponds to the electrical energy charging terminals placed near the route followed by the electric vehicle 10.

[0064] In a third operation, according to a particular exemplary embodiment and as illustrated in [Fig. 3], a display of graphic objects representative of this set of electrical energy charging terminals is controlled, these graphic objects being displayed in a first part 1021 of the screen 102.

[0065] Still according to this example, a first graphic object 21 represents the geographical position of the vehicle 10 on a road map, here a triangle, while a second graphic object 22 represents a route determined by the navigation system.

[0066] Third graphic objects 23 represent, for example, the terminals of the set of electrical energy charging terminals, positioned on the road map according to their geographical position.

[0067] In a fourth operation, an electrical energy charging terminal is selected via a human-machine interface from the set of electrical energy charging terminals based on information representative of a type of cable available at the electrical energy charging terminal.

[0068] According to the example illustrated in [Fig.3], a user makes a short touch press on one of the third graphic objects 23 corresponding to an electrical energy charging terminal.

[0069] In a fifth operation, the display of other graphic objects is then controlled, the other graphic objects being displayed, for example, in one or more second parts 1022, 1023, 1024 of the screen 102, representing particular data relating to the previously selected electrical energy charging station, this particular data having, for example, been received from the remote server 111.

[0070] According to the example illustrated in [Fig. 3], an identifier of the electrical energy charging station is represented by a fourth graphic object 231. Under this fourth graphic object 231 are displayed fifth 232a and sixth graphic objects 232b corresponding respectively to titles of particular data and to a value associated with this particular data for the selected electrical energy charging station, in particular a type of available cable. Other particular data are for example displayed in the form of a seventh graphic object 233, for example an alert or a message.

[0071] The electric vehicle 10 has a traction battery. The term “battery” is used to designate a battery pack comprising one or more batteries, each battery comprising one or more electric accumulators.

[0072] The battery corresponds for example to an electric accumulator designed to supply electrical energy to the vehicle, in particular to power at least one traction motor of the electric vehicle 10. Such a traction motor corresponds for example to a motor connected to a gearbox, to a transmission shaft or to a wheel of the electric vehicle 10. The battery corresponds for example to a lead or lead-acid battery or even to a nickel-aluminium hydride battery, these batteries being designed to quickly supply a large quantity of current and to be quickly recharged.

[0073] A BMS system (from the English “Battery Management System” or in French “Battery control system”) is for example associated or coupled to the traction battery. Such a BMS system makes it possible to obtain or measure one or more parameters of the battery at a given time t, such as for example: - the voltage: total or of each battery cell; - stored energy: total or of each battery cell; - temperature: average temperature, coolant inlet temperature, coolant outlet temperature, temperature of each battery cell; - the state of charge, known as SOC (from the English “State of Charge”) or depth of discharge, known as DOD (from the English “Depth of Discharge”) indicating the charge level of the battery; - the state of health, known as SOH (from the English “State Of Health”); - the current (intensity in amperes) into the battery or out of the battery; and / or - the internal resistance of the battery: ohmic resistance and ionic resistance.

[0074] According to a particular exemplary embodiment, the type of cable compatible with the electric vehicle 10 is a cable configured to ensure communication of charging data between the electric vehicle 10 and the charging terminal, for example relating to the parameters of the traction battery obtained via the BMS.

[0075] According to a particular exemplary embodiment, the type of cable allows mode 3 charging. Such a charging mode is notably presented in the part of the ISO 15118-3:2015 standard relating to “Road vehicles — Communication interface between vehicle and electrical network — Part 3: Requirements relating to the physical layer and the data link layer”.

[0076] Among the other graphic objects, an eighth graphic object 24 is displayed in the second part 1024 of the screen 102, representing a touch button allowing the reservation of the electric energy charging station.

[0077] After having taken note of the type of cable available in the selected charging station, the user makes, for example, a brief press on this touch button. This pressing then triggers the transmission of third data.

[0078] In a sixth operation, these third data representative of a tactile press on the eighth graphic object 24 representative of a command to reserve the electrical energy charging terminal are then sent, for example to the computer or the processor in charge of the process.

[0079] The reception of this third data then triggers, in a seventh operation, the transmission of second data representative of a request to reserve the charging station via a wireless connection, for example to the remote server 111.

[0080] According to an exemplary embodiment, the second data comprises data representative of a date and a time. The date and time are for example determined by the navigation system as a function of the current date and time and a travel time.

[0081] According to another example, the user enters, via the human-machine interface, the date and time at which he plans to arrive at the selected electrical energy charging station.

[0082] Such a process thus makes it possible to reserve an electrical energy charging terminal having a cable compatible with the electric vehicle 10. Thus, when the driver of the vehicle 10 arrives at the electrical energy charging terminal, he is then certain to find an available terminal which will allow the charging of a traction battery of his electric vehicle 10 with electrical energy.

The communication interface 33 corresponds by example to a transmitter configured to transmit and receive information and / or data via the communication channel 330. The communication interface 33 corresponds for example to a wired network of the CAN (from the English “Controller Area Network” or in French “Network of controllers”) type, CAN FD (from the English “Controller Area Network Flexible Data-Rate” or in French “Flexible data rate controller network”), FlexRay (standardized by the ISO 17458 standard) or Ethernet (standardized by the ISO / IEC 802-3 standard).

[0090] According to a particular and non-limiting exemplary embodiment, the device 3 can provide output signals to one or more external devices, such as a display screen 340, touch-sensitive or not, one or more speakers 350 and / or other peripherals 360 (projection system) via the output interfaces 34, 35, 36 respectively. According to a variant, one or other of the external devices is integrated into the device 3.
