Description

DISPOSITIF AUTONOME ET SYSTEME DE REGULATION DE LA CHARGE DES MOYENS DE STOCKAGE INTERNE D'UN VEHICULE ELECTRIQUE DOMAINE TECHNIQUE  AUTONOMOUS DEVICE AND SYSTEM FOR CONTROLLING THE LOAD OF INTERNAL STORAGE MEANS OF AN ELECTRIC VEHICLE TECHNICAL FIELD
L'invention se rapporte au domaine de la régulation de la charge électrique des moyens de stockage interne équipant un véhicule comportant un moteur électrique pour le propulser. De tels véhicules notamment peuvent être de type hybride, c'est-à-dire comporter un premier moteur électrique et un second moteur utilisant une autre source d'énergie, tel que la combustion d'un hydrocarbure notamment. De tels véhicules peuvent également être de type « tout électrique », c'est-à-dire n'être propulsé que par un ou plusieurs moteurs électriques. L'invention vise plus particulièrement un dispositif autonome et un système de régulation de la charge électrique d'une flotte de véhicules équipés chacun d'un dispositif autonome. Une telle régulation permet notamment d'adapter et d'optimiser la production d'énergie électrique en fonction des besoins de l'utilisateur, mais également d'adapter la charge des véhicules en fonction de l'évolution de la consommation et de la production d'énergie électrique. The invention relates to the field of regulating the electric charge of the internal storage means equipping a vehicle comprising an electric motor to propel it. Such vehicles in particular may be hybrid type, that is to say include a first electric motor and a second motor using another energy source, such as the combustion of a particular hydrocarbon. Such vehicles can also be of the "all-electric" type, that is to say, be powered only by one or more electric motors. The invention relates more particularly to an autonomous device and a system for regulating the electric charge of a fleet of vehicles each equipped with an autonomous device. Such a regulation makes it possible in particular to adapt and optimize the production of electrical energy according to the needs of the user, but also to adapt the load of the vehicles according to the evolution of the consumption and the production of electricity. 'electric energy.
ETAT ANTÉRIEUR DE LA TECHNIQUE Tel que décrit dans le document WO 2009/098687, il est connu d'utiliser un système pour contrôler la charge de moyens de stockage interne de véhicules électriques. La régulation de la charge est alors réalisée par les bornes électriques sur lesquelles les véhicules sont connectés pour recharger leur(s) batterie(s). Chaque borne communique alors des informations relatives à la charge d'un véhicule avec un centre de gestion externe, de façon à adapter la charge des véhicules en fonction d'un pic de consommation notamment. Cependant, un tel dispositif nécessite, pour l'utilisateur, de connecter son véhicule à une borne spécifique, de façon à permettre la recharge du ou des moyens de stockage interne de son véhicule. Un tel dispositif est donc lié à un type de borne et n'est pas autonome, en étant agencé à l'extérieur d'un véhicule. PRIOR ART As described in WO 2009/098687, it is known to use a system for controlling the load of internal storage means of electric vehicles. The regulation of the charge is then performed by the electrical terminals on which the vehicles are connected to recharge their battery (s). Each terminal then communicates information relating to the load of a vehicle with an external management center, so as to adapt the load of vehicles according to a peak consumption in particular. However, such a device requires the user to connect his vehicle to a specific terminal, so as to allow the recharging of the internal storage means of his vehicle. Such a device is therefore linked to a type of terminal and is not autonomous, being arranged outside a vehicle.
Par ailleurs, un tel dispositif a été décrit dans le document US-7 402 978. En effet, ce document décrit un dispositif de régulation de la charge électrique agencé à l'intérieur d'un véhicule. Cependant, un tel dispositif ne permet pas de mesurer la quantité d'énergie délivrée lors de la charge des moyens de stockage interne du véhicule. Par conséquent, un tel dispositif ne permet pas de réaliser une facturation à l'utilisateur du dispositif en fonction de la consommation électrique par son véhicule. Furthermore, such a device has been described in US-7 402 978. Indeed, this document describes a device for regulating the electric charge arranged inside a vehicle. However, such a device does not measure the amount of energy delivered during the charging of the internal storage means of the vehicle. Consequently, such a device does not make it possible to bill the user of the device according to the power consumption of his vehicle.
De plus, un tel dispositif n'est pas autonome et est intégré au véhicule lors de sa fabrication. Un tel dispositif ne peut donc pas être installé dans un véhicule existant ou encore être désinstallé rapidement pour être utilisé dans un autre véhicule si nécessaire. In addition, such a device is not autonomous and is integrated into the vehicle during its manufacture. Such a device can not be installed in an existing vehicle or be uninstalled quickly for use in another vehicle if necessary.
Ainsi, un premier objectif de l'invention est de permettre la portabilité du dispositif et de réaliser la mesure de l'énergie fournie durant la charge des moyens de stockage interne du véhicule. Thus, a first objective of the invention is to allow the device to be ported and to measure the energy supplied during the charging of the internal storage means of the vehicle.
On connaît également des systèmes tels que décrits dans le document EP-2 156 978, dans lesquels le dispositif est autonome, mais n'est pas destiné à être agencé dans les véhicules électriques. De plus, un tel dispositif ne présente pas de module de géolocalisation par satellite pour communiquer de façon instantanée la position d'un véhicule électrique ou celle de son point de charge à un centre de gestion. Also known are systems as described in EP-2 156 978, in which the device is autonomous, but is not intended to be arranged in electric vehicles. In addition, such a device does not have a satellite geolocation module for instantaneously communicating the position of an electric vehicle or that of its point of charge to a management center.
Par conséquent, avec ce type de dispositif, le centre de gestion et de régulation de la charge électrique n'est pas apte à optimiser la consommation électrique en fonction des besoins locaux et de la production d'énergie électrique disponible. De plus, avec ce type de dispositif, il est nécessaire pour l'utilisateur de réaliser une intervention spécifique pour associer son véhicule électrique avec la source d'énergie électrique distribuée par un gestionnaire particulier qui peut être différent d'une borne électrique à une autre. Enfïn, un tel dispositif vise à atteindre un coût optimal individuel puisque chaque appareil détermine lui-même son comportement en fonction d'un signal de prix. Par conséquent la gestion de la charge d'une flotte de véhicules n'est pas commandée directement et ne peut permettre d'atteindre efficacement un coût optimum global sur toute la chaîne de valeur, pour une telle flotte. Therefore, with this type of device, the center of management and regulation of the electrical load is not able to optimize the power consumption according to local needs and the production of available electrical energy. In addition, with this type of device, it is necessary for the user to perform a specific intervention to associate his electric vehicle with the source of electrical energy distributed by a particular manager that can be different from one electrical terminal to another . Finally, such a device aims to achieve an optimal individual cost since each device determines its own behavior based on a price signal. Therefore the load management of a vehicle fleet is not directly controlled and can not effectively achieve an overall optimum cost across the entire value chain for such a fleet.
Un autre objectif de l'invention est également de réduire le nombre d'opérations nécessaires à l'utilisateur pour initier la recharge de son véhicule sur une prise électrique la plus standardisée possible et ne présentant éventuellement aucun moyen de mesure de la charge. Another object of the invention is also to reduce the number of operations necessary for the user to initiate charging of his vehicle on a most standardized electrical outlet possible and possibly having no means of measuring the load.
EXPOSE DE L'INVENTION L'invention concerne donc un dispositif autonome permettant de réaliser une régulation de la charge électrique des moyens de stockage interne équipant un véhicule électrique, ce dispositif étant destiné à être agencé dans le véhicule électrique et connecté en série sur une alimentation électrique de charge des moyens de stockage interne. Selon l'invention, ce dispositif comporte : SUMMARY OF THE INVENTION The invention therefore relates to an autonomous device for regulating the electric charge of the internal storage means equipping an electric vehicle, this device being intended to be arranged in the electric vehicle and connected in series to a power supply. electric charging means of internal storage. According to the invention, this device comprises:
- un interrupteur pilotable permettant d'autoriser ou non le passage d'énergie électrique entre une source d'énergie externe et les moyens de stockage interne du véhicule ;  a controllable switch enabling the passage of electrical energy between an external power source and the internal storage means of the vehicle;
- des moyens de détection et de mesure de la tension et/ou de l'intensité du courant de charge des moyens de stockage interne ;  means for detecting and measuring the voltage and / or the intensity of the charging current of the internal storage means;
- des moyens d'enregistrement de valeurs représentatives de la charge électrique ; means for recording values representative of the electric charge;
- un premier module de communication sans fil permettant, d'une part, de transmettre à un centre de gestion extérieur les valeurs représentatives de la charge électrique en fonction du temps, et d'autre part, de recevoir du centre de gestion une consigne de charge spécifique adressée à ce dispositif en particulier. Autrement dit, un tel dispositif peut être rapporté dans un véhicule existant et connecté sur l'alimentation électrique de charge des moyens de stockage interne, et notamment de la ou des batteries du véhicule. Il peut également être, si nécessaire, désinstallé, pour être agencé par exemple dans un autre véhicule. Par ailleurs, il permet de gérer en temps réel l'énergie électrique fournie au véhicule. Cette mesure étant horodatée au moyen d'une unité centrale avec horloge, il est possible d'enregistrer les valeurs de la tension et/ou de l'intensité du courant de charge avec un intervalle de temps régulier fin. a first wireless communication module making it possible, on the one hand, to transmit to an external management center the values representative of the electric charge as a function of time, and on the other hand, to receive from the management center a setpoint of specific load addressed to this particular device. In other words, such a device can be added in an existing vehicle and connected to the charging power supply of the internal storage means, and in particular of the battery or batteries of the vehicle. It can also be, if necessary, uninstalled, to be arranged for example in another vehicle. Moreover, it makes it possible to manage in real time the electrical energy supplied to the vehicle. Since this measurement is time stamped by means of a central unit with a clock, it is possible to record the values of the voltage and / or the intensity of the charging current with a regular fine time interval.
Par ailleurs, ce dispositif peut comporter également un module de géo- localisation permettant de transmettre au centre de gestion extérieur la position du véhicule lors de la charge de ses moyens de stockage interne, et ainsi d'identifier le site hôte et le point de charge auquel le véhicule est connecté. Furthermore, this device may also include a geolocation module for transmitting to the external management center the position of the vehicle during the charging of its internal storage means, and thus to identify the host site and the point of charge the vehicle is connected to.
Le centre de gestion peut également réveiller un dispositif autonome en veille en lui envoyant un signal sur le numéro de téléphone correspondant au premier module de communication sans fil. Ce signal peut consister en un appel ou message court textuel (SMS pour « Short Message Service »). A réception, le dispositif autonome peut alors s'activer de façon à se mettre en relation avec le centre de gestion et échanger les informations voulues. The management center can also wake up a stand-alone device on standby by sending it a signal on the telephone number corresponding to the first wireless communication module. This signal may consist of a short message call or SMS message. Upon receipt, the autonomous device can then be activated so as to contact the management center and exchange the desired information.
En pratique, le dispositif autonome peut comporter un second module de communication sans fil permettant de communiquer des informations avec une interface portable. Cette interface portable, prenant par exemple la forme d'un téléphone mobile, permet à un utilisateur de s'identifier et de communiquer directement avec le dispositif de son véhicule afin d'en consulter l'état ou de lui transmettre une consigne relative au mode de recharge souhaité. In practice, the autonomous device may include a second wireless communication module for communicating information with a portable interface. This portable interface, for example taking the form of a mobile phone, allows a user to identify himself and communicate directly with the device of his vehicle in order to consult the status or to send him instructions on the mode desired recharge.
Avantageusement, le premier module de communication sans fil peut être un module de téléphonie mobile utilisant les protocoles de télécommunication adaptés (GPRS, EDGE ou UMTS notamment). Selon un mode de réalisation particulier, le second module de communication sans fil peut être un module permettant une mise en réseau de courte distance entre des appareils électroniques et utilisant un protocole de communication de type réseau personnel sans fil (WPAN pour « Wire-less Personal Area Network ») basé notamment sur les technologies BLUETOOTH, ZIGBEE ou WI-FI. En effet, de tels protocoles de communication permettent de relier entre eux plusieurs appareils informatiques au sein d'un même réseau, et ce, sans nécessiter de connexion filaire. Matériellement, les premier et second modules peuvent être formés par un seul équipement. Advantageously, the first wireless communication module may be a mobile telephone module using the adapted telecommunication protocols (GPRS, EDGE or UMTS in particular). According to a particular embodiment, the second wireless communication module can be a module allowing short-distance networking between electronic devices and using a wireless personal network type communication protocol (WPAN for "Wire-less Personal"). Area Network ") based in particular on BLUETOOTH, ZIGBEE or WI-FI technologies. In fact, such communication protocols make it possible to connect several computing devices to one another within the same network, without the need for a wired connection. Materially, the first and second modules can be formed by a single device.
En d'autres termes, le dispositif ne comporte pas d'interface pour permettre à un utilisateur de saisir la consigne de charge de son véhicule. L'utilisateur, par un terminal de son choix, communique avec le centre de gestion pour notamment lui transmettre une consigne relative au mode de charge souhaité. In other words, the device has no interface to allow a user to enter the charge of his vehicle. The user, through a terminal of his choice, communicates with the management center in particular to send him instructions on the desired charging mode.
La communication peut être établie directement par un quelconque moyen entre le centre de gestion et le terminal de l'utilisateur. Elle peut également être relayée par le dispositif autonome à l'aide des deux modules de communication. Le terminal de l'utilisateur est une interface qui peut être portable et peut notamment se présenter sous la forme d'un téléphone portable, d'un agenda électronique, d'une tablette tactile ou de tout autre appareil électronique. The communication can be established directly by any means between the management center and the user's terminal. It can also be relayed by the autonomous device using the two communication modules. The user's terminal is an interface that can be portable and can in particular be in the form of a mobile phone, an organizer, a touch pad or other electronic device.
Comme déjà évoqué, l'invention concerne également un système de régulation de la charge électrique d'une flotte de véhicules électriques équipés chacun d'un dispositif tel que précédemment décrit. As already mentioned, the invention also relates to a system for regulating the electric charge of a fleet of electric vehicles each equipped with a device as previously described.
Selon l'invention, un tel système de régulation comporte un centre de gestion apte à recevoir et mémoriser pour chaque véhicule de la flotte : According to the invention, such a regulation system comprises a management center capable of receiving and memorizing for each vehicle of the fleet:
- les valeurs représentatives de la charge et de l'énergie électrique fournie au véhicule en fonction du temps ;  - the representative values of the load and the electrical energy supplied to the vehicle as a function of time;
- les consignes relatives au mode de charge souhaité transmises par l'utilisateur ; - instructions on the desired charging mode transmitted by the user;
- la position du véhicule durant la charge et la référence du point de charge associé. Un tel système de régulation permet donc d'identifier et d'anticiper les besoins en énergie électrique en fonction de l'état des charges estimé des véhicules de la flotte. Un tel centre de gestion permet également d'identifier et de localiser le point de charge sur lequel le dispositif est connecté en recoupant la position effective d'un véhicule détectée par un module de géo- localisation avec des informations contenues dans des bases de données de points de charge. L'utilisateur a alors, au même titre que l'opérateur du centre de gestion, la possibilité d'associer la position géographique avec le point de charge. - the position of the vehicle during the load and the reference of the associated load point. Such a regulation system thus makes it possible to identify and anticipate the electrical energy requirements according to the state of the estimated loads of the vehicles of the fleet. Such a management center also makes it possible to identify and locate the point of charge on which the device is connected by intersecting the actual position of a vehicle detected by a geolocation module with information contained in data bases. charging points. The user then, as well as the operator of the management center, the possibility of associating the geographical position with the point of load.
Le centre de gestion comporte un organe de communication constitué d'un troisième module de communication sans fil similaire au premier module de communication du dispositif autonome. Il permet de recevoir les valeurs représentatives de la charge électrique et de l'énergie électrique fournie au véhicule en fonction du temps par chaque véhicule électrique de la flotte, et de transmettre une consigne de charge au dispositif de chaque véhicule électrique de la flotte. The management center comprises a communication element consisting of a third wireless communication module similar to the first communication module of the autonomous device. It makes it possible to receive the representative values of the electric charge and of the electrical energy supplied to the vehicle as a function of time by each electric vehicle of the fleet, and to transmit a charging instruction to the device of each electric vehicle of the fleet.
Par ailleurs, l'organe de communication du centre de gestion peut également comporter un module de communication fïlaire connecté à un réseau informatique. Ce mode de réalisation permet ainsi à l'utilisateur de communiquer avec le centre de gestion, lorsqu'il ne dispose pas d'une interface portable. Furthermore, the communication unit of the management center may also include a wire communication module connected to a computer network. This embodiment thus allows the user to communicate with the management center, when he does not have a portable interface.
Cet organe de communication assure donc l'échange des informations entre le centre de gestion et l'utilisateur. Ce dernier peut transmettre une consigne de charge au centre de gestion, pour notamment demander une charge forcée de son véhicule si celui-ci doit être rechargé le plus rapidement possible, ou une charge libre lorsque le véhicule doit être immobilisé pour plusieurs heures. Dans le cadre de la charge libre, l'utilisateur dispose de la possibilité de donner au centre de gestion un ensemble de paramètres représentatifs de l'énergie à charger. Ces paramètres peuvent notamment prendre les formes suivantes :  This communication device thus ensures the exchange of information between the management center and the user. The latter can transmit a charge to the management center, in particular to request a forced load of his vehicle if it must be recharged as quickly as possible, or a free charge when the vehicle must be immobilized for several hours. As part of the free load, the user has the possibility to give the management center a set of parameters representative of the energy to be loaded. These parameters can take the following forms:
- une heure cible pour la fin de charge, un niveau de charge souhaité, un niveau de charge initial ;  - a target time for the end of charging, a desired charge level, an initial charge level;
- une heure cible pour la fin de charge et une durée de charge ;  - a target time for the end of charge and a charging time;
- une heure cible pour la fin de charge et une quantité d'énergie électrique ;  - a target time for the end of charge and a quantity of electrical energy;
- une heure de début de charge et une durée de charge ;  - one hour of charge start and one charge duration;
- une heure de début de charge et une quantité d'énergie électrique. DESCRIPTION SOMMAIRE DES FIGURES - an hour of start of charge and a quantity of electrical energy. SUMMARY DESCRIPTION OF THE FIGURES

As shown in FIG. 1, such an autonomous device 1 is positioned inside a vehicle and connected in series with a load power supply 3 of the internal storage means 2 of the vehicle. As shown, such a device 1 comprises several elements and in particular means 4 for detecting the voltage and / or the intensity of the charging current of the internal storage means 2.

Pour ce faire, le centre de gestion 8 comporte un troisième module de communication sans fil 15, permettant de recevoir les valeurs représentatives de la charge et de l'énergie électrique consommée par chaque véhicule 14 de la flotte. Ce troisième module de communication sans fil 15 permet également de transmettre aux différents dispositifs 1 de chaque véhicule 14 une consigne de charge conformément aux instructions de l'utilisateur, transmises via une interface portable 12. As already mentioned, and as shown in FIG. 3, the invention also relates to a regulation system 21, making it possible to regulate the electric charge of a fleet of electric vehicles 14 on electrical sockets 16. Such a system control system 21 comprises a management center 8 communicating with each vehicle 14 of the fleet.

This third wireless communication module 15 also makes it possible to transmit to the various devices 1 of each vehicle 14 a charging instruction in accordance with the instructions of the user transmitted via a portable interface 12.
Selon une autre alternative et tel que représenté à la figure 4, le système de régulation 31 peut comporter un centre de gestion 18 comportant un organe de communication filaire 32, de façon à permettre à un utilisateur de s'identifier au moyen d'un ordinateur 33 et de transmettre au centre de gestion 18 une consigne relative au mode de charge souhaité. De cette manière, l'utilisateur n'a pas besoin d'une interface portable pour transmettre au centre de gestion 18 la consigne de charge du véhicule électrique.
