Description

VEHICULE AUTOMOBILE COMPRENANT UN MOYEN DE CHAUFFAGE DE CELLULES DE BATTERIE SUR LA BASE D’UN COURANT ALTERNATIF D’ONDULEUR, ET PROCEDE ET PROGRAMME SUR LA BASE D’UN TEL VEHICULEMOTOR VEHICLE COMPRISING A MEANS FOR HEATING BATTERY CELLS ON THE BASIS OF AN INVERTER ALTERNATING CURRENT, AND METHOD AND PROGRAM ON THE BASIS OF SUCH A VEHICLE

L’invention concerne le domaine des véhicules automobile à moteur de traction électrique, équipés d’une batterie de traction.The invention relates to the field of motor vehicles with electric traction motors, equipped with a traction battery.

Dans ce domaine la température de la batterie influence ses performances de sorte qu’en cas de température basse il est nécessaire de chauffer les cellules de la batterie.In this area the temperature of the battery influences its performance so that in the event of low temperature it is necessary to heat the battery cells.

Le brevet EP3675273B1 a proposé une stratégie de chauffage cellule avec du courant alternatif, mais les performances de chauffage peuvent encore être améliorées.Patent EP3675273B1 proposed a cell heating strategy with alternating current, but the heating performance can still be improved.

Un objectif de la présente invention est de remédier aux défauts de l’art antérieur, et notamment de proposer une architecture électrique de véhicule automobile permettant d’améliorer les performances de chauffage sur la base d’un courant alternatif issu de l’onduleur.An objective of the present invention is to remedy the defects of the prior art, and in particular to propose an electrical architecture of a motor vehicle making it possible to improve heating performance on the basis of an alternating current coming from the inverter.

Pour atteindre cet objectif, l’invention propose un véhicule automobile comprenant une architecture électrique qui comprend :
- une machine électrique ;
- un module d’onduleur ;
- une batterie d’au moins une cellule ;
caractérisé en ce que l’architecture électrique comprend un module de capacité de filtrage connecté en parallèle du module d’onduleur, le module de capacité de filtrage comprenant un interrupteurTo achieve this objective, the invention proposes a motor vehicle comprising an electrical architecture which comprises:
- an electric machine;
- an inverter module;
- a battery of at least one cell;
characterized in that the electrical architecture comprises a filtering capacity module connected in parallel to the inverter module, the filtering capacity module comprising a switch

Avantageusement, l’invention permet de venir chauffer les cellules au moyen d'un courant alternatif produit par l'onduleur, sans nécessiter de système de chauffage additionnel à l'architecture décrite ci-dessus.Advantageously, the invention makes it possible to heat the cells by means of an alternating current produced by the inverter, without requiring an additional heating system to the architecture described above.

Par ailleurs, elle présente l’avantage d’augmenter la puissance thermique dissipée (~+50%) par rapport au procédé défini dans le brevet EP3675273B1. Cela se fait grâce à l’ajout de l’interrupteur sur la branche de la capacité de filtrage. Lorsque cet interrupteur est en position « ouverte », le signal de chauffage généré au moyen de l’onduleur permet d’augmenter la puissance de chauffage au niveau de la cellule.Furthermore, it has the advantage of increasing the thermal power dissipated (~+50%) compared to the process defined in patent EP3675273B1. This is done by adding the switch on the filter capacity branch. When this switch is in the “open” position, the heating signal generated by the inverter increases the heating power at the cell level.

Selon une variante, le module de capacité de filtrage comprend une branche de capacité connectant un dispositif de capacité à l’interrupteur, de sorte à activer ou désactiver la branche de capacité.Alternatively, the filter capacitance module includes a capacitance branch connecting a capacitance device to the switch, so as to activate or deactivate the capacitance branch.

Cela permet d’activer le mode chauffage en commandant une ouverture de l’interrupteur ou d’activer le filtrage en commandant une fermeture de l’interrupteur.This allows heating mode to be activated by opening the switch or activating filtering by closing the switch.

Selon une variante, le module de capacité de filtrage comprend deux branches de capacité connectant chacune un dispositif de capacité à l’interrupteur, de sorte à activer l’une ou l’autre branche de capacité.According to a variant, the filtering capacity module comprises two capacity branches each connecting a capacity device to the switch, so as to activate one or the other capacity branch.

Cela permet d’activer le mode chauffage par une branche spécifique avec une capacité spécialement dimensionnée à cet effet ; et un mode filtrage par une branche spécifique avec une capacité spécialement dimensionnée à cet effet.This allows heating mode to be activated by a specific branch with a capacity specially sized for this purpose; and a filtering mode by a specific branch with a capacity specially sized for this purpose.

L’invention porte également sur un procédé de chauffage de batterie pour un véhicule automobile l’invention, caractérisé en ce qu’il comprend les étapes suivantes :
- commander le module d’onduleur pour générer un courant alternatif ; et
- chauffer la batterie en ouvrant l’interrupteur.The invention also relates to a battery heating method for a motor vehicle of the invention, characterized in that it comprises the following steps:
- control the inverter module to generate alternating current; And
- heat the battery by opening the switch.

Un autre objet de l’invention concerne un programme d’ordinateur comprenant des instructions de code de programme pour l’exécution des étapes du procédé de chauffage selon l’invention, lorsque ledit programme fonctionne sur un ordinateur.Another object of the invention relates to a computer program comprising program code instructions for executing the steps of the heating method according to the invention, when said program operates on a computer.

L’invention sera davantage détaillée par la description de modes de réalisation non limitatifs, et sur la base des figures annexées illustrant des variantes de l’invention, dans lesquelles :
- illustre schématiquement une architecture électrique pour un véhicule selon une première variante préférée ;
- illustre schématiquement des profils de courants de batterie dans l’architecture de la , avec interrupteur ouvert ou avec interrupteur fermé ;
- illustre schématiquement des profils de courants similaires à ceux de la , où la fréquence du signal correspondant est augmentée ;
- illustre schématiquement une architecture électrique pour un véhicule selon une deuxième variante préférée.The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which:
- schematically illustrates an electrical architecture for a vehicle according to a first preferred variant;
- schematically illustrates battery current profiles in the architecture of the , with switch open or with switch closed;
- schematically illustrates current profiles similar to those of the , where the frequency of the corresponding signal is increased;
- schematically illustrates an electrical architecture for a vehicle according to a second preferred variant.

L’invention permet, dans le cadre d'une architecture électrique comprenant un pack batterie B d'au moins une cellule, un onduleur MO incluant une capacité de filtrage MC, et au moins une machine électrique ME, de venir chauffer les cellules au moyen d'un courant alternatif produit par l'onduleur MO.The invention allows, within the framework of an electrical architecture comprising a battery pack B of at least one cell, an inverter MO including a filtering capacity MC, and at least one electric machine ME, to heat the cells by means of an alternating current produced by the MO inverter.

L’invention permet ainsi de chauffer la batterie sans nécessiter de système de chauffage additionnel à l'architecture décrite ci-dessus, illustrée en .The invention thus makes it possible to heat the battery without requiring an additional heating system to the architecture described above, illustrated in .

Par ailleurs, l’invention présente l'avantage d'augmenter la puissance thermique dissipée (~+50%) par rapport au procédé défini dans le brevet EP3675273B1. Cela se fait grâce à l'ajout d'un interrupteur sur la branche de la capacité de filtrage. Lorsque cet interrupteur est en position « ouverte », le signal de chauffage généré au moyen de l'onduleur MO permet d'augmenter la puissance de chauffage au niveau de la cellule.Furthermore, the invention has the advantage of increasing the thermal power dissipated (~+50%) compared to the process defined in patent EP3675273B1. This is done by adding a switch on the filtering capacity branch. When this switch is in the “open” position, the heating signal generated by means of the MO inverter makes it possible to increase the heating power at the cell level.

Dans une chaine de traction conventionnelle, les cellules sont chauffées au moyen d'une résistance chauffante haute tension. L'eau du circuit caloporteur est ainsi chauffée puis vient par circulation au niveau du pack batterie B pour chauffer les cellules. On a donc un chauffage indirect des cellules au moyen de l'eau. Avec cette invention, le chauffage de la cellule est direct, il n'y a donc pas d'énergie perdue due au chauffage du volume d'eau du circuit caloporteur. L’invention permet donc de ne pas utiliser de résistance chauffante.In a conventional powertrain, the cells are heated by means of a high voltage heating resistor. The water in the heat transfer circuit is thus heated and then circulates at the level of battery pack B to heat the cells. We therefore have indirect heating of the cells by means of water. With this invention, the heating of the cell is direct, so there is no energy lost due to heating the volume of water in the heat transfer circuit. The invention therefore makes it possible not to use a heating resistance.

Les cellules ayant une résistance interne non nulle, lorsqu'un courant alternatif est généré aux bornes de celles-ci, un dégagement de chaleur va être produit par effet joule au sein de cellule, et donc la réchauffer.Since the cells have a non-zero internal resistance, when an alternating current is generated across them, heat will be released by the Joule effect within the cell, and therefore heat it up.

Un courant alternatif peut être produit au niveau des cellules au moyen de l'architecture suivante :
- une machine électrique ME ;
- un onduleur MO ;
- une capacité de filtrage MC en parallèle de l'onduleur MO avec un interrupteur S permettant d'ouvrir ou de fermer ce circuit ;
- une batterie B constituée d'au moins une cellule ; et
- au moins un calculateur permettant de piloter l'onduleur MO, et la machine ME, et de collecter certaines mesures effectuées au niveau du véhicule.Alternating current can be produced at the cell level using the following architecture:
- an ME electric machine;
- an MO inverter;
- a filtering capacity MC in parallel with the inverter MO with a switch S allowing this circuit to be opened or closed;
- a battery B made up of at least one cell; And
- at least one computer making it possible to control the MO inverter, and the ME machine, and to collect certain measurements carried out at the vehicle level.

Cette architecture se différencie de celle du brevet EP3675273B1 au sens où elle possède un interrupteur S sur la branche de la capacité de filtrage MC.This architecture differs from that of patent EP3675273B1 in the sense that it has a switch S on the branch of the filtering capacity MC.

L'onduleur MO peut alors être piloté de sorte à générer un courant alternatif au niveau du pack batterie B. Les modes de pilotage de l'onduleur MO pour produire les profils de courant, sont identiques à ceux décrits dans le brevet EP3675273B1.The MO inverter can then be controlled so as to generate an alternating current at the level of the battery pack B. The control modes of the MO inverter to produce the current profiles are identical to those described in patent EP3675273B1.

Les modes de pilotage de l'onduleur MO pour produire les profils de courant peuvent être identiques à ceux décrits dans le brevet EP3675273B1. Avec un pilotage séquentiel d’éléments de l'onduleur deux par deux, on obtient les profils de courant I illustrés en au niveau de la cellule. La référence O1 concerne l’interrupteur S ouvert ; et la référence C1 concerne l’interrupteur S fermé.The control modes of the MO inverter to produce the current profiles can be identical to those described in patent EP3675273B1. With sequential control of elements of the inverter two by two, we obtain the current profiles I illustrated in at the cell level. Reference O1 concerns switch S open; and the reference C1 concerns the switch S closed.

On constate que les profils de courant I sont modifiés lorsque l’interrupteur S sur la capacité de filtrage MC, est en position ouverte O1 ou fermée C1.We see that the current profiles I are modified when the switch S on the filtering capacitor MC is in the open position O1 or closed position C1.

En position fermée C1, on constate qu’une importante partie du pic de courant négatif est atténuée par la capacité de filtrage MC.In the closed position C1, we see that a significant part of the negative current peak is attenuated by the filtering capacitance MC.

Lorsque l’interrupteur S est en position ouverte O1, l'énergie restituée par la machine électrique ME n'est pas du tout atténuée par la capacité de filtrage MC, et par conséquent le pic de courant minimum est plus important. On constate aussi que la durée du plateau à 0A est allongée dans cette configuration.When the switch S is in the open position O1, the energy released by the electrical machine ME is not at all attenuated by the filtering capacity MC, and consequently the minimum current peak is greater. We also see that the duration of the plateau at 0A is lengthened in this configuration.

La puissance de chauffage à la cellule dépend principalement de l'intensité RMS du signal. Pour augmenter cette valeur il faut réduire le temps passé sur le plateau à 0 A. Cela peut être réalisé dans la configuration où l’interrupteur S est en position "ouverte" en augmentant la fréquence du signal (référence O2) jusqu'à ce que le plateau à 0A disparaisse.The heating power to the cell depends mainly on the RMS intensity of the signal. To increase this value it is necessary to reduce the time spent on the plate to 0 A. This can be achieved in the configuration where the switch S is in the "open" position by increasing the frequency of the signal (reference O2) until the plateau at 0A disappears.

On obtient alors les profils de courant I de la . La référence C2 concerne la fermeture de l’interrupteur S.We then obtain the current profiles I of the . Reference C2 concerns the closing of switch S.

On constate que l'intensité RMS peut ainsi être augmentée jusqu'à 50% lorsque de l’interrupteur S est piloté en position "ouverte" O2. Par conséquent, la puissance thermique dissipée au niveau de la cellule augmente dans la même proportion.We see that the RMS intensity can thus be increased by up to 50% when the switch S is controlled in the "open" position O2. Consequently, the thermal power dissipated at the cell level increases in the same proportion.

On peut proposer une architecture alternative (illustrée en ) permettant également d'améliorer la puissance de chauffage au niveau des cellules.We can propose an alternative architecture (illustrated in ) also making it possible to improve the heating power at the cell level.

Dans cette architecture, deux capacités de filtrages MC sont disposées en parallèle de la batterie B et de l'onduleur MO. Une de ces capacités correspond à la capacité utilisée lorsque le mode de chauffage des cellules par courant alternatif est désactivé, et la seconde est utilisée uniquement lorsque la stratégie de chauffage des cellules est activée. La capacité de filtrage utilisée en mode chauffage est dimensionnée de sorte à obtenir la puissance de chauffage désirée.In this architecture, two filtering capacities MC are arranged in parallel with the battery B and the inverter MO. One of these capacities is the capacity used when the AC cell heating mode is disabled, and the second is used only when the cell heating strategy is enabled. The filtering capacity used in heating mode is sized to obtain the desired heating power.

La position de l’interrupteur S permettant de sélectionner la capacité à utiliser sera déterminée par le calculateur en fonction de l'état d'activation de la stratégie de chauffage. Si le chauffage est activé, la capacité correspondante sera activée.
The position of switch S allowing selection of the capacity to be used will be determined by the computer depending on the activation state of the heating strategy. If heating is activated, the corresponding capacity will be activated.
