L’invention concerne les vĂ©hicules ayant au moins une batterie rechargeable0 en courant continu et en courant alternatif, et plus prĂ©cisĂ©ment le contrĂŽle des recharges de telles batteries. The invention relates to vehicles having at least one rechargeable battery 0 in direct current and in alternating current, and more precisely the control of the recharging of such batteries.
Etat de la technique State of the art
Certains vĂ©hicules comprennent au moins une batterie qui peut ĂȘtre rechargĂ©e5 en courant continu et en courant alternatif (selon le choix de l’utilisateur) grĂące Ă  des premiĂšre et seconde prises qui sont solidarisĂ©es fixement Ă  une embase qu’ils comprennent dans une partie avant ou arriĂšre. Plus prĂ©cisĂ©ment, la premiĂšre prise de l’embase est adaptĂ©e Ă  une recharge en courant continu et comporte gĂ©nĂ©ralement deux premiĂšres broches, et la seconde prise de0 l’embase est adaptĂ©e Ă  une recharge en courant alternatif et comporte gĂ©nĂ©ralement au moins deux secondes broches (et le plus souvent sept broches). Some vehicles include at least one battery which can be recharged5 in direct current and in alternating current (according to the choice of the user) thanks to first and second plugs which are fixedly secured to a base which they include in a front part or back. More specifically, the first socket of the socket is suitable for DC charging and generally has two first pins, and the second socket of the socket is suitable for AC charging and generally has at least two second pins ( and most often seven pins).
Lorsque l’on veut rĂ©aliser une recharge en courant continu, respectivement alternatif, de la batterie d’un vĂ©hicule, on connecte une prise externe (par5 exemple d’un poste de recharge) Ă  la premiĂšre, respectivement seconde, prise de ce vĂ©hicule. When you want to recharge the battery of a vehicle with direct current, respectively alternating current, an external socket (for example from a charging station) is connected to the first, respectively second, socket of this vehicle.
Les connexions et dĂ©connexions successives des prises externes sur les broches des premiĂšre et seconde prises de l’embase par lesquelles circule le courant provoquent une usure de ces broches et donc les contacts de ces0 derniĂšres avec les prises externes deviennent de moins en moins francs. Par consĂ©quent, lorsqu’il y a un jeu entre contacts mĂ©tal/mĂ©tal il peut parfois apparaĂźtre des petits arcs Ă©lectriques qui peuvent gĂ©nĂ©rer une augmentation de la tempĂ©rature de l’embase potentiellement dangereuse pour le vĂ©hicule, la prise de l’embase et l’utilisateur qui rĂ©alise la dĂ©connexion de la prise externe. Il est donc important de surveiller la tempĂ©rature de l’embase pendant chaqueThe successive connections and disconnections of the external sockets on the pins of the first and second sockets of the base through which the current flows cause wear of these pins and therefore the contacts of the latter with the external sockets become less and less frank. Consequently, when there is a clearance between metal / metal contacts it can sometimes small electric arcs appear which can generate an increase in the temperature of the base that is potentially dangerous for the vehicle, the base socket and the user who disconnects the external socket. It is therefore important to monitor the manifold temperature during each
5 recharge, et en particulier lorsqu’elle se fait en courant continu du fait de l’intensitĂ© importante de ce dernier. 5 recharging, and in particular when it is done in direct current because of the high intensity of the latter.
Pour ce faire, il a Ă©tĂ© proposĂ© d’adjoindre un premier capteur de tempĂ©rature Ă  chacune des deux premiĂšres broches de la premiĂšre prise de l’embase par lesquelles circule le courant continu, et un second capteur de tempĂ©rature Ă 0 chacune des deux secondes broches de la seconde prise de l’embase par lesquelles circule le courant alternatif, et d’interrompre la recharge lorsque l’un au moins des premiers et seconds capteurs dĂ©tecte une tempĂ©rature supĂ©rieure Ă  un seuil (typiquement Ă©gal Ă  90 °C). En gĂ©nĂ©ral cette interruption est accompagnĂ©e d’un affichage (par exemple d’un voyant de service) sur un5 Ă©cran du vĂ©hicule afin de prĂ©venir son utilisateur. To do this, it has been proposed to add a first temperature sensor to each of the first two pins of the first socket of the base through which the direct current flows, and a second temperature sensor to each of the two second pins of the second socket of the base through which the alternating current circulates, and to interrupt the recharging when at least one of the first and second sensors detects a temperature above a threshold (typically equal to 90 ° C.). In general, this interruption is accompanied by a display (for example by a service light) on a screen of the vehicle in order to warn its user.
Ce mode de fonctionnement prĂ©sente plusieurs inconvĂ©nients. En effet, si les quatre premiers et seconds capteurs sont simultanĂ©ment dĂ©faillants, on ne peut pas disposer de mesure de tempĂ©rature et donc il n’y aura pas d’interruption de recharge dĂ©cidĂ©e en raison de la tempĂ©rature de l’embase,0 ce qui peut s’avĂ©rer dangereux pour l’utilisateur (risque de brulure) et/ou pour le vĂ©hicule et/ou pour la borne de recharge (risque d’incendie). Par ailleurs, le capteur qui dĂ©tecte une tempĂ©rature supĂ©rieure au seuil peut faire l’objet (Ă©ventuellement temporairement) d’un dysfonctionnement. Par consĂ©quent, une interruption de recharge peut ĂȘtre dĂ©cidĂ©e Ă  tort du fait de ce5 dysfonctionnement, ce qui peut ĂȘtre dommageable pour l’utilisateur puisqu’il va rĂ©cupĂ©rer un vĂ©hicule dont la batterie n’aura pas Ă©tĂ© rechargĂ©e et donc possiblement inutilisable si son groupe motopropulseur est tout Ă©lectrique. L’invention a donc notamment pour but d’amĂ©liorer la situation. 0 PrĂ©sentation de l’invention This mode of operation has several drawbacks. Indeed, if the first four and second sensors are simultaneously faulty, it is not possible to have a temperature measurement and therefore there will be no interruption of recharging decided due to the temperature of the base, 0 which may be dangerous for the user (risk of burns) and / or for the vehicle and / or for the charging station (risk of fire). In addition, the sensor that detects a temperature above the threshold may be the subject (possibly temporarily) of a malfunction. Consequently, an interruption of recharging can be decided wrongly because of this malfunction, which can be damaging for the user since he will recover a vehicle whose battery has not been recharged and therefore possibly unusable if his group powerplant is all electric. One aim of the invention is therefore to improve the situation. 0 Presentation of the invention
Elle propose notamment Ă  cet effet un vĂ©hicule comprenant au moins une batterie rechargeable et une embase Ă  laquelle sont solidarisĂ©es fixement, d’une part, une premiĂšre prise adaptĂ©e Ă  une recharge de la batterie en courant continu et comportant deux premiĂšres broches pourvues chacune d’un premier capteur mesurant la tempĂ©rature, et, d’autre part, une seconde prise adaptĂ©e Ă  une recharge de la batterie en courant alternatif et comportant deux secondes broches pourvues chacune d’un second capteur mesurant la tempĂ©rature. It proposes in particular for this purpose a vehicle comprising at least one rechargeable battery and a base to which are fixedly secured, on the one hand, a first socket suitable for recharging the battery with current. DC and comprising two first pins each provided with a first sensor measuring the temperature, and, on the other hand, a second socket suitable for recharging the battery with alternating current and comprising two second pins each provided with a second sensor measuring temperature.
5 Ce vĂ©hicule se caractĂ©rise par le fait qu’il comprend aussi au moins un processeur et au moins une mĂ©moire agencĂ©s pour effectuer les opĂ©rations consistant, pendant une recharge avec la premiĂšre prise, Ă  Ă  :5 This vehicle is characterized by the fact that it also comprises at least one processor and at least one memory arranged to perform the operations consisting, during recharging with the first socket, in:
- détecter une défaillance simultanée desdits premiers capteurs par une analyse de leurs signaux,0 - puis déclencher une interruption de cette recharge lorsque lesdits premiers capteurs sont simultanément détectés défaillants. - detecting a simultaneous failure of said first sensors by an analysis of their signals, 0 - then triggering an interruption of this recharging when said first sensors are simultaneously detected to be faulty.
Ainsi, lors d’une recharge en courant continu on Ă©vite tout risque d’échauffement anormal de l’embase (compte tenu de l’importance du courant qui circule dans la premiĂšre prise), car on considĂšre que la dĂ©faillance5 simultanĂ©e des deux premiers capteurs est trĂšs improbable en l’absence de dysfonctionnement au niveau de cette premiĂšre prise. Thus, when recharging with direct current, any risk of abnormal heating of the base (taking into account the importance of the current flowing in the first socket) is avoided, because it is considered that the simultaneous failure5 of the first two sensors is very unlikely in the absence of malfunction at the level of this first intake.

Description dĂ©taillĂ©e de l’invention Detailed description of the invention
L’invention a notamment pour but de proposer un vĂ©hicule V comprenant au5 moins une batterie BR pouvant ĂȘtre rechargĂ©e en courant continu ou en courant alternatif de façon contrĂŽlĂ©e, de maniĂšre Ă  Ă©viter les surchauffes de son embase de recharge ER. The invention aims in particular to provide a vehicle V comprising at least one battery BR that can be recharged with direct current or alternating current in a controlled manner, so as to avoid overheating of its charging base ER.
Dans ce qui suit, on considĂšre, Ă  titre d’exemple non limitatif, que le vĂ©hicule V est de type automobile. Il s’agit par exemple d’une voiture, comme illustrĂ© sur0 la figure 1 . Mais l’invention n’est pas limitĂ©e Ă  ce type de vĂ©hicule. Elle concerne en effet tout type de vĂ©hicule comprenant un groupe motopropulseur (ou GMP) tout Ă©lectrique ou hybride et comprenant au moins une batterie rechargeable en courant continu ou en courant alternatif selon le choix de l’utilisateur. Ainsi, elle concerne les vĂ©hicules terrestres (vĂ©hicules utilitaires,5 camping-cars, minibus, cars, camions, motocyclettes, engins de voirie, engins de chantier, engins agricoles, engins de loisir (motoneige, kart), engins Ă  chenille(s), et engins d’exploration Ă  Ă©quipage), les bateaux et les aĂ©ronefs, par exemple. In what follows, it is considered, by way of nonlimiting example, that the vehicle V is of the automobile type. This is for example a car, as shown in Figure 1. But the invention is not limited to this type of vehicle. It relates in fact to any type of vehicle comprising an all-electric or hybrid powertrain (or GMP) and comprising at least one rechargeable battery in direct current or in alternating current according to the choice of the user. Thus, it concerns land vehicles (utility vehicles, 5 motorhomes, minibuses, coaches, trucks, motorcycles, road machinery, construction machinery, agricultural machinery, leisure machinery (snowmobile, kart), caterpillar machinery (s) , and crewed exploration devices), ships and aircraft, for example.
Par ailleurs, on considĂšre dans ce qui suit, Ă  titre d’exemple non limitatif, que0 le GMP du vĂ©hicule V est tout Ă©lectrique. Il comprend donc au moins une machine motrice Ă©lectrique produisant notamment du couple pour ses dĂ©placements Ă  partir de l’énergie stockĂ©e dans une batterie rechargeable. Mais le GMP du vĂ©hicule V pourrait ĂȘtre hybride et donc comprendre au moins une machine motrice Ă©lectrique et au moins une machine motrice non Ă©lectrique (Ă©ventuellement thermique). Furthermore, it is considered in what follows, by way of nonlimiting example, that the GMP of the vehicle V is all electric. It therefore comprises at least one electric drive machine producing in particular torque for its movements from the energy stored in a rechargeable battery. But the GMP of the vehicle V could be hybrid and therefore comprise at least one electric driving machine and at least one non-electric driving machine (possibly thermal).
On a schématiquement représenté sur la figure 1 un véhicule V, selonThere is schematically shown in Figure 1 a vehicle V, according to
5 l’invention, comprenant une chaĂźne de transmission (ici Ă  GMP tout Ă©lectrique), une embase (de recharge) ER comprenant des premiĂšre P1 et seconde P2 prises, et au moins un processeur PR et au moins une mĂ©moire MD. 5 the invention, comprising a transmission chain (here in all-electric GMP), an ER (recharging) base comprising first P1 and second P2 taken, and at least one PR processor and at least one MD memory.
Comme illustré non limitativement, le GMP du véhicule V comprend ici une machine motrice MM électrique, associée à une batterie BR rechargeable, et0 un dispositif de couplage DC. De plus, la chaßne de transmission comprend notamment, en complément de son GMP, un arbre moteur AM et un arbre de transmission AT. As illustrated without limitation, the GMP of the vehicle V here comprises an electric drive machine MM, associated with a rechargeable battery BR, and a DC coupling device. In addition, the transmission chain comprises in particular, in addition to its GMP, an AM motor shaft and an AT transmission shaft.
La machine motrice MM Ă©lectrique est chargĂ©e de produire du couple sur ordre d’un calculateur de supervision du GMP (non illustrĂ©), Ă  partir de l’énergie qui5 est stockĂ©e dans la batterie BR. Elle (MM) dĂ©livre ce couple sur l’arbre moteur AM qui est aussi couplĂ© au dispositif de couplage DC. Ce couple est ici produit pour un train de roues motrices (ici le premier train T1) qui est couplĂ© au dispositif de couplage DC via l’arbre de transmission AT. Le couple produit est donc ici transmis au premier train T1 lorsque le dispositif de couplage DC0 couple l’arbre moteur AM Ă  l’arbre de transmission AT. The electric drive machine MM is responsible for producing torque on the order of a GMP supervision computer (not shown), from the energy which is stored in the battery BR. It (MM) delivers this torque to the AM motor shaft which is also coupled to the DC coupling device. This torque is produced here for a driving wheel train (here the first train T1) which is coupled to the DC coupling device via the AT driveshaft. The torque produced is therefore transmitted here to the first train T1 when the DC0 coupling device couples the motor shaft AM to the transmission shaft AT.
Dans l’exemple illustrĂ© non limitativement sur la figure 1 le premier train T 1 est situĂ© Ă  l’avant du vĂ©hicule V, et de prĂ©fĂ©rence, et comme illustrĂ©, couplĂ© Ă  l’arbre de transmission AT via un diffĂ©rentiel (ici avant) D1 . Mais dans une variante ce train T1 pourrait ĂȘtre celui rĂ©fĂ©rencĂ© T2 qui est situĂ© Ă  l’arriĂšre du5 vĂ©hicule V. In the example illustrated without limitation in FIG. 1, the first train T 1 is located at the front of the vehicle V, and preferably, and as illustrated, coupled to the transmission shaft AT via a differential (here before) D1 . But in a variant this train T1 could be the one referenced T2 which is located at the rear of the 5 vehicle V.
Le dispositif de couplage DC peut, par exemple, ĂȘtre une boĂźte de dĂ©multiplication de rĂ©gime d’arbre. Mais il pourrait aussi s’agir d’un crabot ou d’un embrayage. The DC coupling device can, for example, be a shaft speed reduction gearbox. But it could also be a dog clutch or a clutch.
La batterie BR est rechargeable en courant continu ou en courant alternatif0 (selon le choix de l’utilisateur), via un module d’alimentation MA qui est connectĂ© Ă  l’embase (de recharge) ER. Par exemple, cette batterie BR peut ĂȘtre de type basse tension (typiquement 220 V ou 400 V ou encore 600 V). Mais elle pourrait aussi ĂȘtre de type moyenne tension ou trĂšs basse tension (typiquement 48V). The battery BR is rechargeable in direct current or in alternating current0 (according to the choice of the user), via a power supply module MA which is connected to the base (of recharge) ER. For example, this battery BR can be of the low voltage type (typically 220 V or 400 V or else 600 V). But it could also be of the medium voltage or very low voltage type (typically 48V).
Cette batterie BR alimente aussi, comme illustré non limitativement sur la figureThis BR battery also supplies power, as illustrated without limitation in FIG.
1 , des équipements électriques du véhicule V qui sont, par exemple, connectés1, electrical equipment of the vehicle V which is, for example, connected
5 Ă  un rĂ©seau de bord RB. A cet effet, la batterie BR est, ici, couplĂ©e au rĂ©seau de bord RB via un convertisseur CV de type DC/DC, ainsi qu’éventuellement via un module de distribution d’énergie MDE. 5 to an RB on-board network. For this purpose, the BR battery is here coupled to the RB on-board network via a DC / DC type CV converter, as well as possibly via an MDE energy distribution module.
La premiĂšre prise P1 est solidarisĂ©e fixement Ă  l’embase ER et est adaptĂ©e Ă  une recharge de la batterie BR en courant continu. Comme illustrĂ© sur la figure0 2, elle comprend deux premiĂšres broches B1 pourvues chacune d’un premier capteur C1 mesurant la tempĂ©rature localement et par lesquelles circule le courant continu. The first P1 socket is fixedly attached to the ER base and is suitable for recharging the BR battery in direct current. As illustrated in FIG. 2, it comprises two first pins B1 each provided with a first sensor C1 measuring the temperature locally and through which the direct current flows.
La seconde prise P2 est solidarisĂ©e fixement Ă  l’embase ER et est adaptĂ©e Ă  une recharge de la batterie BR en courant alternatif. Comme illustrĂ© sur la5 figure 2, elle comprend notamment deux secondes broches B2 pourvues chacune d’un second capteur C2 mesurant la tempĂ©rature localement et par lesquelles circule le courant alternatif. On notera que dans l’exemple illustrĂ© non limitativement sur la figure 2 la seconde prise P2 comprend sept broches, dont les deux secondes broches B2, du fait qu’elle constitue une prise de type0 CCS2 (mais l’invention s’applique quel que soit le type de prise). The second socket P2 is fixedly attached to the ER base and is suitable for recharging the battery BR in alternating current. As illustrated in FIG. 2, it comprises in particular two second pins B2 each provided with a second sensor C2 measuring the temperature locally and through which the alternating current circulates. It will be noted that in the example illustrated without limitation in FIG. 2, the second socket P2 comprises seven pins, including the two second pins B2, due to the fact that it constitutes a socket of type 0 CCS2 (but the invention applies whatever either the type of plug).
De prĂ©fĂ©rence, chacun des premiers C1 et seconds C2 capteurs mesure la tempĂ©rature de l’embase ER. Preferably, each of the first C1 and second C2 sensors measures the temperature of the ER base.
Le module d’alimentation MA assure l’interface entre la batterie BR et l’embase ER. Il est chargĂ© de contrĂŽler l’alimentation de la batterie BR lors de chaque5 phase de recharge pendant laquelle une prise externe (par exemple d’un poste de recharge) est connectĂ©e soit Ă  la premiĂšre prise P1 , soit Ă  la seconde prise P2. The MA power module provides the interface between the BR battery and the ER base. It is responsible for monitoring the power supply to the BR battery during each recharging phase during which an external socket (for example from a charging station) is connected either to the first socket P1 or to the second socket P2.
Le processeur PR et la mĂ©moire MD sont agencĂ©s pour effectuer les opĂ©rations consistant, pendant une recharge avec la premiĂšre prise P1 , Ă 0 dĂ©clencher l’interruption de cette recharge lorsque les deux premiers capteurs C1 sont dĂ©faillants, quelle que soit la tempĂ©rature mesurĂ©e par au moins un second capteur C2. On considĂšre ici qu’un capteur est (dans un Ă©tat) dĂ©faillant lorsque, aprĂšs analyse de son signal, le processeur PR dĂ©termine par exemple : The processor PR and the memory MD are arranged to perform the operations consisting, during a recharge with the first socket P1, to trigger the interruption of this recharge when the first two sensors C1 are faulty, whatever the temperature measured by at least a second sensor C2. It is considered here that a sensor is (in a state) faulty when, after analysis of its signal, the processor PR determines by example :
- que ce signal n’est plus fournit, signifiant plus de mesure de tempĂ©rature, ou- that this signal is no longer supplied, meaning no more temperature measurement, or
- que ce signal est en dehors d’une plage de valeurs prĂ©dĂ©terminĂ©es, ou- that this signal is outside a range of predetermined values, or
- que Ă©volution de ce signal est anormale, par exemple une Ă©volution trop- that the evolution of this signal is abnormal, for example an evolution that is too
5 brusque. 5 abrupt.
Ainsi, ce n’est qu’à condition que les deux premiers capteurs C1 soient simultanĂ©ment dans un Ă©tat dĂ©faillant pendant une recharge en courant continu que l’on interrompt automatiquement cette recharge. La dĂ©faillance simultanĂ©e des deux premiers capteurs C1 Ă©tant trĂšs improbable en0 l’absence de dysfonctionnement au niveau de la premiĂšre prise P1 , on dĂ©cide d’éviter tout risque d’échauffement anormal de l’embase ER, compte tenu de l’importance du courant qui circule dans la premiĂšre prise P1. Par consĂ©quent, il n’y a plus de risque de brulure de l’utilisateur ou d’incendie du vĂ©hicule V. 5 Le processeur PR peut, par exemple, ĂȘtre un processeur de signal numĂ©rique (ou DSP (« Digital Signal Processor »)). Ce processeur PR peut comprendre des circuits intĂ©grĂ©s (ou imprimĂ©s), ou bien plusieurs circuits intĂ©grĂ©s (ou imprimĂ©s) reliĂ©s par des connections filaires ou non filaires. On entend par circuit intĂ©grĂ© (ou imprimĂ©) tout type de dispositif apte Ă  effectuer au moins une0 opĂ©ration Ă©lectrique ou Ă©lectronique. Ainsi, il peut, par exemple, s’agir d’un microcontrĂŽleur. Thus, it is only on condition that the first two C1 sensors are simultaneously in a faulty state during a DC recharge that this recharge is automatically interrupted. The simultaneous failure of the first two sensors C1 being very improbable in the absence of a malfunction at the level of the first socket P1, it is decided to avoid any risk of abnormal heating of the ER base, given the importance of the current. which circulates in the first outlet P1. Consequently, there is no longer any risk of burning the user or of fire in the vehicle V. 5 The processor PR can, for example, be a digital signal processor (or DSP (“Digital Signal Processor”). ). This PR processor can comprise integrated circuits (or printed), or else several integrated circuits (or printed) connected by wired or non-wired connections. By integrated circuit (or printed circuit) is meant any type of device capable of performing at least one electrical or electronic operation. So, for example, it could be a microcontroller.
La mĂ©moire MD est vive afin de stocker des instructions pour la mise en oeuvre par le processeur PR d’une partie au moins du procĂ©dĂ© de contrĂŽle dĂ©crit plus loin (et donc de ses fonctionnalitĂ©s). 5 On notera que dans l’exemple illustrĂ© non limitativement sur les figures 1 et 2, le processeur PR et la mĂ©moire MD font partie d’un calculateur CA qui fait lui- mĂȘme partie du module d’alimentation MA et qui est rĂ©alisĂ© sous la forme d’une combinaison de circuits ou composants Ă©lectriques ou Ă©lectroniques (ou « hardware ») et de modules logiciels (ou « software »). Mais dans une variante0 de rĂ©alisation non illustrĂ©e le processeur PR et la mĂ©moire MD pourraient faire partie d’un calculateur, Ă©ventuellement dĂ©diĂ© au contrĂŽle des recharges en fonction de l’état des premier C1 et second C2 capteurs, et externe au module d’alimentation MA, bien qu’étant couplĂ© Ă  ce dernier (MA) pour l’informer des interruptions de recharge dĂ©cidĂ©es. The memory MD is live in order to store instructions for the implementation by the processor PR of at least part of the control method described below (and therefore of its functionalities). It will be noted that in the example illustrated without limitation in FIGS. 1 and 2, the processor PR and the memory MD form part of a computer CA which itself forms part of the power supply module MA and which is produced under the form of a combination of electrical or electronic circuits or components (or "hardware") and software modules (or "software"). But in an alternative embodiment, not illustrated, the processor PR and the memory MD could form part of a computer, possibly dedicated to the control of recharging according to the state of the first C1 and second C2 sensors, and external to the power supply module. MA, although being coupled to the latter (MA) to inform him of charging interruptions decided.
On notera Ă©galement que si le processeur PR dĂ©tecte que seul l’un des deux premiers capteurs C1 est dĂ©faillant il va continuer Ă  analyser la tempĂ©rature mesurĂ©e par l’autre premier capteur C1 (non dĂ©faillant) et donc dĂ©cideraNote also that if the PR processor detects that only one of the first two sensors C1 is faulty, it will continue to analyze the temperature measured by the other first sensor C1 (not faulty) and therefore will decide
5 d’interrompre la recharge en courant continu si cette tempĂ©rature mesurĂ©e est supĂ©rieure Ă  un seuil de tempĂ©rature. 5 to interrupt the direct current recharging if this measured temperature is above a temperature threshold.
Par exemple, le seuil de tempĂ©rature peut ĂȘtre compris entre 80 °C et 100°C. Ainsi, il peut, par exemple, ĂȘtre choisi Ă©gal Ă  90 °C. For example, the temperature threshold can be between 80 ° C and 100 ° C. Thus, it can, for example, be chosen equal to 90 ° C.
On notera Ă©galement que le processeur PR et la mĂ©moire MD sont0 prĂ©fĂ©rentiellement agencĂ©s pour effectuer les opĂ©rations consistant Ă  dĂ©clencher un signalement Ă  un passager du vĂ©hicule V de l’interruption de recharge (en courant continu comme en courant alternatif). It will also be noted that the processor PR and the memory MD are preferably arranged to perform the operations of triggering a signal to a passenger of the vehicle V of the recharging interruption (in direct current as well as in alternating current).
On comprendra que ce signalement a lieu lorsque l’utilisateur dĂ©cide de se servir de nouveau de son vĂ©hicule V aprĂšs la recharge de sa batterie BR.5 Par exemple, ce signalement peut se faire par affichage d’un tĂ©moin de service ou d’un message textuel d’avertissement dĂ©diĂ© sur un Ă©cran du vĂ©hicule V, comme par exemple celui du tableau de bord ou celui du combinĂ© central, et/ou par diffusion d’un message sonore (ou audio) dĂ©diĂ© via au moins un haut- parleur prĂ©sent dans le vĂ©hicule V. 0 On notera Ă©galement que le processeur PR et la mĂ©moire MD sont prĂ©fĂ©rentiellement agencĂ©s, en cas de dĂ©faillance d’au moins un premier C1 ou second C2 capteur pendant une durĂ©e qui est supĂ©rieure Ă  un seuil temporel, pour effectuer les opĂ©rations consistant Ă  dĂ©clencher un signalement Ă  un passager du vĂ©hicule V. On considĂšre ici que lorsqu’une dĂ©faillance d’un5 premier C1 ou second C2 capteur est durable (trop longue) elle doit ĂȘtre signalĂ©e Ă  l’utilisateur du vĂ©hicule V. Par exemple, ce signalement peut se faire par affichage d’un tĂ©moin de service ou d’un message textuel d’avertissement dĂ©diĂ© sur un Ă©cran du vĂ©hicule V, comme par exemple celui du tableau de bord ou celui du combinĂ© central, et/ou par diffusion d’un message sonore (ou audio)0 dĂ©diĂ© via au moins un haut-parleur prĂ©sent dans le vĂ©hicule V. It will be understood that this signaling takes place when the user decides to use his vehicle V again after recharging his battery BR.5 For example, this signaling can be done by displaying a service indicator light or a dedicated textual warning message on a screen of vehicle V, such as for example that of the instrument panel or that of the central instrument panel, and / or by broadcasting a dedicated audio (or audio) message via at least one loudspeaker present in the vehicle V. 0 It will also be noted that the processor PR and the memory MD are preferably arranged, in the event of failure of at least one first C1 or second C2 sensor for a period which is greater than a time threshold, to perform the operations consisting in triggering a signal to a passenger of vehicle V. It is considered here that when a failure of a first C1 or second C2 sensor is lasting (too long) it must be signaled to the user of vehicle V. For example , this little report t be done by displaying a service indicator light or a dedicated warning text message on a vehicle screen V, such as that of the instrument panel or that of the central instrument panel, and / or by broadcasting a dedicated audio (or audio) message 0 via at least one loudspeaker present in the vehicle V.
On notera Ă©galement que le processeur PR et la mĂ©moire MD sont prĂ©fĂ©rentiellement agencĂ©s, en cas de dĂ©faillance d’au moins un premier C1 ou second C2 capteur, pour effectuer les opĂ©rations consistant Ă  dĂ©clencher un stockage dans une mĂ©moire d’un code de dĂ©faut associĂ© Ă  chaque capteur dĂ©faillant. Ainsi, lors d’un passage dans un service aprĂšs-vente il est possible, en accĂ©dant au contenu de cette mĂ©moire, de savoir si un premier C1 ou second C2 capteur a Ă©tĂ© considĂ©rĂ© comme dĂ©faillant (temporairement ouIt will also be noted that the processor PR and the memory MD are preferably arranged, in the event of failure of at least one first C1 or second C2 sensor, to perform the operations consisting in triggering storage in a memory of a fault code associated with each faulty sensor. Thus, during a visit to an after-sales service it is possible, by accessing the content of this memory, to know whether a first C1 or second C2 sensor has been considered as faulty (temporarily or
5 durablement). Cela permet alors de dĂ©cider s’il faut changer ce premier C1 ou second C2 capteur dĂ©faillant ou toute l’embase ER (avec ses premiĂšre P1 et seconde P2 prises). 5 sustainably). This then makes it possible to decide whether to change this first C1 or second C2 faulty sensor or the entire ER base (with its first P1 and second P2 taken).
La mĂ©moire de stockage des codes de dĂ©faut peut, par exemple, faire partie du calculateur CA ou plus gĂ©nĂ©ralement du module d’alimentation MA. Mais0 elle peut aussi ĂȘtre non dĂ©diĂ©e et donc utilisĂ©e pour le stockage de nombreuses informations de vie du vĂ©hicule V. Dans ce dernier cas elle peut, par exemple, faire partie de ce que l’homme de l’art appelle parfois le boĂźtier de servitude intelligent (ou BSI - Ă©quipement de supervision). La transmission Ă  la mĂ©moire des messages contenant les codes de dĂ©faut se fait alors via un5 rĂ©seau de communication embarquĂ© dans le vĂ©hicule V, et Ă©ventuellement multiplexĂ©. The fault code storage memory can, for example, be part of the AC computer or more generally of the MA power module. But0 it can also be non-dedicated and therefore used for storing a great deal of information on the life of the vehicle V. In the latter case it can, for example, form part of what those skilled in the art sometimes call the service box. intelligent (or BSI - supervision equipment). The messages containing the fault codes are then transmitted to the memory via a communication network on board the vehicle V, and possibly multiplexed.
En prĂ©sence de la derniĂšre option le processeur PR et la mĂ©moire MD peuvent ĂȘtre Ă©ventuellement agencĂ©s pour effectuer les opĂ©rations consistant Ă  dĂ©clencher le stockage dans la mĂ©moire du code de dĂ©faut associĂ© Ă  chaque0 capteur dĂ©faillant en correspondance d’une durĂ©e de dĂ©faillance de ce dernier. On notera Ă©galement que le processeur PR et la mĂ©moire MD peuvent ĂȘtre agencĂ©s, pendant une recharge avec la seconde prise P2 (et donc en courant alternatif), pour effectuer les opĂ©rations consistant Ă  dĂ©clencher une interruption de cette recharge lorsque les seconds capteurs C2 sont dĂ©faillants5 et que la tempĂ©rature mesurĂ©e par au moins un premier capteur C1 est supĂ©rieure au seuil de tempĂ©rature (dĂ©crit plus haut) ou que les premiers capteurs C1 sont aussi dĂ©faillants. In the presence of the last option, the processor PR and the memory MD can optionally be arranged to perform the operations consisting in triggering the storage in the memory of the fault code associated with each faulty sensor in correspondence of a duration of failure of the latter. It will also be noted that the processor PR and the memory MD can be arranged, during recharging with the second socket P2 (and therefore in alternating current), to perform the operations consisting in triggering an interruption of this recharging when the second sensors C2 are faulty5. and that the temperature measured by at least a first sensor C1 is greater than the temperature threshold (described above) or that the first sensors C1 are also faulty.
On considĂšre en effet qu’un potentiel dysfonctionnement au niveau de la seconde prise P2 (ayant ou non entraĂźnĂ© la dĂ©faillance simultanĂ©e des deux0 seconds capteurs C2) est moins grave qu’un potentiel dysfonctionnement de la premiĂšre prise P1 , compte tenu de l’intensitĂ© relativement faible du courant qui circule dans la seconde prise P2. Il faut donc ici que le dĂ©passement du seuil de tempĂ©rature soit dĂ©tectĂ© ou bien que les premiers capteurs C1 soient aussi dĂ©faillants, en complĂ©ment de la dĂ©tection de dĂ©faillance des deux seconds capteurs C2, pour que l’interruption d’une recharge en courant alternatif soit dĂ©cidĂ©e. It is in fact considered that a potential malfunction at the level of the second outlet P2 (having or not led to the simultaneous failure of the two second sensors C2) is less serious than a potential malfunction of the first outlet P1, given the intensity. relatively low current flowing through the second socket P2. It is therefore necessary here that the exceeding of the temperature threshold is detected or that the first sensors C1 are also faulty, in addition to the failure detection of the two second sensors C2, so that the interruption of an alternating current recharge is decided.
On notera également, comme illustré non limitativement sur la figure 2, que leIt will also be noted, as illustrated without limitation in FIG. 2, that the
5 calculateur CA peut aussi comprendre, en complĂ©ment de sa mĂ©moire vive MD et de son processeur PR, une mĂ©moire de masse MM, notamment pour le stockage des mesures de tempĂ©rature (issues des premiers C1 et seconds C2 capteurs), et de donnĂ©es intermĂ©diaires intervenant dans tous ses calculs et traitements. Par ailleurs, ce calculateur CA peut aussi comprendre une0 interface d’entrĂ©e IE pour la rĂ©ception d’au moins les mesures de tempĂ©rature pour les utiliser dans des calculs ou traitements, Ă©ventuellement aprĂšs les avoir mises en forme et/ou dĂ©modulĂ©es et/ou amplifiĂ©es, de façon connue en soi, au moyen d’un processeur de signal numĂ©rique PR’. De plus, ce calculateur CA peut aussi comprendre une interface de sortie IS, notamment pour dĂ©livrer ses5 ordres ou commandes d’interruption de recharge (au moins pour le module d’alimentation MA) et ses messages contenant des signalements de dĂ©faillance de capteur(s) ou des codes de dĂ©faut. 5 CA computer can also include, in addition to its RAM MD and its processor PR, a mass memory MM, in particular for storing temperature measurements (from the first C1 and second C2 sensors), and intermediate data involved in all its calculations and treatments. Furthermore, this computer CA can also include an input interface IE for the reception of at least the temperature measurements for use in calculations or processing, possibly after having formatted and / or demodulated and / or amplified. , in a manner known per se, by means of a digital signal processor PR '. In addition, this CA computer can also include an IS output interface, in particular for delivering its recharging interrupt orders or commands (at least for the power supply module MA) and its messages containing sensor failure reports (s). ) or fault codes.
L’invention peut aussi ĂȘtre considĂ©rĂ©e sous la forme d’un procĂ©dĂ© de contrĂŽle destinĂ© Ă  ĂȘtre mis en oeuvre dans le vĂ©hicule V dĂ©crit ci-avant afin de0 permettre le contrĂŽle des recharges de sa batterie BR. The invention can also be considered in the form of a control method intended to be implemented in the vehicle V described above in order to allow control of the recharging of its battery BR.
Ce procĂ©dĂ© de contrĂŽle comprend une Ă©tape 10-40 dans laquelle on interrompt une recharge avec la premiĂšre prise P1 lorsque les premiers capteurs C1 sont dĂ©faillants (simultanĂ©ment), quelle que soit la tempĂ©rature mesurĂ©e par au moins un second capteur C2. 5 On a schĂ©matiquement illustrĂ© sur la figure 3 un exemple d’algorithme mettant en oeuvre un procĂ©dĂ© de contrĂŽle de recharge selon l’invention. This control method comprises a step 10-40 in which a recharging with the first socket P1 is interrupted when the first sensors C1 fail (simultaneously), regardless of the temperature measured by at least one second sensor C2. 5 An example of an algorithm implementing a recharge control method according to the invention has been schematically illustrated in FIG. 3.
L’algorithme comprend une sous-Ă©tape 10 dans laquelle, en cas de dĂ©marrage d’une recharge en courant continu (via la premiĂšre prise P1 ), on obtient et analyse les mesures de tempĂ©rature effectuĂ©es par les premiers C1 et0 seconds C2 capteurs. The algorithm includes a sub-step 10 in which, in the event of starting a DC recharge (via the first socket P1), the temperature measurements taken by the first C1 and 0 second C2 sensors are obtained and analyzed.
Puis, si dans une premiÚre sous-étape 20 on détecte que les deux premiers capteurs C1 sont simultanément défaillants, alors dans une seconde sous- étape 30 on interrompt la recharge en courant continu qui est en cours. Puis, dans une sous-étape 40, on peut signaler à un passager du véhicule V cette interruption de recharge et/ou stocker dans une mémoire au moins un code de défaut (éventuellement associé à une durée de défaillance). Then, if in a first sub-step 20 it is detected that the first two sensors C1 are simultaneously faulty, then in a second sub-step 30 the direct current recharging which is in progress is interrupted. Then, in a sub-step 40, it is possible to signal this interruption of recharging to a passenger of the vehicle V and / or to store in a memory at least one fault code (possibly associated with a fault duration).
On notera qu’une ou plusieurs sous-Ă©tapes de l’étape 10-40 du procĂ©dĂ© de 5 contrĂŽle peuvent ĂȘtre effectuĂ©es par des composants diffĂ©rents. Ainsi, le procĂ©dĂ© de contrĂŽle peut-ĂȘtre mis en oeuvre par une pluralitĂ© de processeurs de signal numĂ©rique, mĂ©moire vive, mĂ©moire de masse, interface d’entrĂ©e, interface de sortie. Note that one or more sub-steps of step 10-40 of the control method can be performed by different components. Thus, the control method can be implemented by a plurality of digital signal processors, random access memory, mass memory, input interface, output interface.
On notera Ă©galement que l’invention propose aussi un produit programme0 d’ordinateur (ou programme informatique) comprenant un jeu d’instructions qui, lorsqu’il est exĂ©cutĂ© par des moyens de traitement de type circuits Ă©lectroniques (ou hardware), comme par exemple le processeur PR, est propre Ă  mettre en oeuvre le procĂ©dĂ© de contrĂŽle de recharge dĂ©crit ci-avant pour contrĂŽler les recharges de la batterie BR du vĂ©hicule V. 5 It will also be noted that the invention also provides a computer program product (or computer program) comprising a set of instructions which, when it is executed by processing means of the electronic circuit (or hardware) type, such as for example the processor PR is suitable for implementing the recharging control method described above to control the recharges of the battery BR of the vehicle V. 5
