Description
L’invention se rapporte au domaine des groupes motopropulseurs de véhicules électriques et hybrides, ainsi que celui des bornes de recharge rapide et chargeurs embarqués de ces véhicules.The invention relates to the field of powertrains of electric and hybrid vehicles, as well as that of fast charging stations and on-board chargers for these vehicles.
L’invention concerne plus précisément les chargeurs embarqués de véhicule, en particulier sur des facultés d’extension de recharge.The invention relates more specifically to on-board vehicle chargers, in particular to charging extension capabilities.
L’art antérieur a proposé des systèmes dits de recharge rapide. Dans ces systèmes, une recharge rapide d’un véhicule électrique disposant d’une batterie à 800V, se fait par une borne de charge rapide à 800V. Une tension continue de 800V est appliquée directement aux bornes de la batterie 800V du véhicule.The prior art has proposed so-called fast charging systems. In these systems, rapid charging of an electric vehicle with an 800V battery is done by an 800V fast charging terminal. A direct voltage of 800V is applied directly to the terminals of the vehicle's 800V battery.
Par ailleurs, une recharge rapide d’un véhicule électrique disposant d’une batterie à 400V, se fait par une borne de charge rapide à 400V. Une tension continue de 400V est appliquée directement aux bornes de la batterie 400V du véhicule.Furthermore, fast charging of an electric vehicle with a 400V battery is done using a 400V fast charging station. A direct voltage of 400V is applied directly to the terminals of the vehicle's 400V battery.
Malheureusement, une recharge rapide d’un véhicule électrique disposant d’une batterie à 800V, ne peut pas se faire par une borne de charge rapide à 400V. En effet, la tension disponible est inférieure à 800V donc le courant délivré est nul.Unfortunately, fast charging of an electric vehicle with an 800V battery cannot be done using a 400V fast charging station. In fact, the available voltage is less than 800V so the current delivered is zero.
En outre, une recharge d’un véhicule électrique disposant d’une batterie à 400V, effectuée sur une borne de charge rapide à 800V, nécessite que la borne s’adapte à cette tension inférieure.In addition, recharging an electric vehicle with a 400V battery, carried out at an 800V fast charging terminal, requires the terminal to adapt to this lower voltage.
Un objectif de l’invention est de remédier aux inconvénients de l’art antérieur, et notamment de proposer une solution de recharge adaptée à différentes tensions de batterie et de source.An objective of the invention is to remedy the drawbacks of the prior art, and in particular to propose a charging solution adapted to different battery and source voltages.
Pour atteindre cet objectif, l’invention propose un chargeur embarqué pour un véhicule automobile, configurée pour charger une batterie de traction du véhicule automobile sur une source de courant, le chargeur embarqué comprenant :
- un module de filtre entrant configuré pour être connecté à la source de courant ;
- un module de correction de puissance connecté au module de filtre entrant ;
- un module de condensateur connecté au module de correction de puissance ;
- un module de transformateur connecté au module de condensateur, le module de transformateur ayant un primaire et un secondaire ;
- un module de commutateur connecté au module de transformateur, le module de commutateur comportant deux commutateurs ;
- un module de filtre sortant connecté au module de commutateur, et configuré pour être connecté à la batterie de traction,
le module de filtre sortant comprenant un sous-module de stimulation,
dans lequel les commutateurs sont configurés pour alimenter un point milieu du secondaire du module de transformateur,
le secondaire étant bidirectionnel et connecté à deux demi-ponts de MOSFET de sorte à réaliser un redressement de tension,
dans lequel chaque demi-pont de MOSFET coopère avec au moins une inductance, et est configuré pour fonctionner en décalage de phase par rapport à l’autre demi-pont de sorte à ne pas saturer le module de transformateur.To achieve this objective, the invention proposes an on-board charger for a motor vehicle, configured to charge a traction battery of the motor vehicle on a current source, the on-board charger comprising:
- an incoming filter module configured to be connected to the current source;
- a power correction module connected to the incoming filter module;
- a capacitor module connected to the power correction module;
- a transformer module connected to the capacitor module, the transformer module having a primary and a secondary;
- a switch module connected to the transformer module, the switch module comprising two switches;
- an outgoing filter module connected to the switch module, and configured to be connected to the traction battery,
the outgoing filter module comprising a stimulation sub-module,
in which the switches are configured to supply a midpoint of the secondary of the transformer module,
the secondary being bidirectional and connected to two MOSFET half-bridges so as to achieve voltage rectification,
in which each MOSFET half-bridge cooperates with at least one inductor, and is configured to operate in phase shift relative to the other half-bridge so as not to saturate the transformer module.
Avantageusement, l’invention permet d’utiliser, indifféremment, une borne de recharge rapide à 400V ou 800V pour un véhicule disposant d’une batterie à 800V.Advantageously, the invention makes it possible to use, indifferently, a 400V or 800V fast charging station for a vehicle having an 800V battery.
De même, elle permet d’utiliser, indifféremment, une borne charge rapide à 400V ou 800V pour un véhicule disposant d’une batterie à 400V ou à 800V.Likewise, it allows you to use, indifferently, a 400V or 800V fast charging terminal for a vehicle with a 400V or 800V battery.
Selon la variante considérée, l’invention permet de charger tout véhicule (400/800V) sur une borne de recharge en tensions alternatives monophasées, biphasées et triphasées.Depending on the variant considered, the invention makes it possible to charge any vehicle (400/800V) on a charging station with single-phase, two-phase and three-phase alternating voltages.
Plus précisément, l’ajout de deux commutateurs et permet d’alimenter le point milieu du secondaire du transformateur 4. Le secondaire étant bi-directionnel, le redressement est réalisé par les deux demi-ponts de MOSFET. Ces deux demi-ponts ainsi que les deux inductances du transformateur sont utilisés pour convertir le 400V en 800V, et réalisant une fonction de stimulation (ou « boost » en langue anglaise).More precisely, the addition of two switches allows powering the midpoint of the secondary of transformer 4. The secondary being bi-directional, the rectification is carried out by the two MOSFET half-bridges. These two half-bridges as well as the two inductances of the transformer are used to convert 400V into 800V, and performing a stimulation function (or “boost” in English).
L’invention simplifie le montage de chargeur embarqué en diminuant le nombre de commutateurs de l’art antérieur qui sont peu disponibles et volumineux. En outre, le volume d’intégration est plus favorable en raison du mode de fonctionnement du secondaire du convertisseur.The invention simplifies the assembly of on-board chargers by reducing the number of switches of the prior art which are poorly available and bulky. In addition, the integration volume is more favorable due to the secondary operating mode of the converter.
Selon une variante, le chargeur embarqué est configuré pour fonctionner alternativement en courant alternatif monophasé, biphasé et triphasé.According to one variant, the on-board charger is configured to operate alternately in single-phase, two-phase and three-phase alternating current.
Cela permet d’être adapté aux différentes sources de courant correspondantes pour une batterie de traction donnée.This makes it possible to adapt to the different current sources corresponding to a given traction battery.
Selon une variante, le chargeur embarqué est configuré pour fonctionner alternativement sur une borne de recharge rapide à 400V ou 800V.According to one variant, the on-board charger is configured to operate alternately on a 400V or 800V fast charging terminal.
Cela permet d’être adapté aux différentes batteries de traction et sources de courant correspondantes.This makes it possible to adapt to different traction batteries and corresponding current sources.
L’invention porte en outre sur un système de chargeur embarqué comprenant une batterie de traction et un chargeur embarqué selon l’invention, dans lequel le module de filtre sortant est connecté à la batterie de traction.The invention further relates to an on-board charger system comprising a traction battery and an on-board charger according to the invention, in which the outgoing filter module is connected to the traction battery.
Selon une variante, le système de chargeur embarqué comprend en outre un module de connexion pour connecter le chargeur embarqué à une source de courant.According to a variant, the on-board charger system further comprises a connection module for connecting the on-board charger to a current source.
L’invention concerne également, un véhicule automobile comprenant un chargeur embarqué selon l’invention.The invention also relates to a motor vehicle comprising an on-board charger according to the invention.
Un autre objet de l’invention concerne un procédé de charge d’une batterie de traction d’un véhicule automobile sur une source de courant, comprenant au moins une étape de charge de la batterie de traction au moyen d’un un chargeur embarqué selon l’invention.Another object of the invention relates to a method of charging a traction battery of a motor vehicle on a current source, comprising at least one step of charging the traction battery by means of an on-board charger according to the invention.
L’invention sera davantage détaillée par la description non-limitative de variantes, et sur la base de la
L’invention concerne un chargeur embarqué OBC d’un véhicule automobile, du type permettant de charger une batterie de traction B dudit véhicule sur une source de courant S telle qu’une borne de recharge.The invention relates to an OBC on-board charger for a motor vehicle, of the type allowing a traction battery B of said vehicle to be charged on a current source S such as a charging station.
Comme on peut le voir sur la figure annexée, le chargeur embarqué OBC comprend, de l’extrémité de connexion à la source S, à l’extrémité de connexion à la batterie B :
- un module de filtre entrant 1 ou filtre entrant ;
- un module de correction de puissance 2 de type PFC, connu en lui-même ;
- un module de condensateur 3 de type DC-Link, connu en lui-même ;
- un module de transformateur 4 connecté au module de condensateur 3, ayant un primaire T1 et un secondaire T2 ;
- un module de commutateur 5 connecté au module de transformateur 4, qui comporte deux commutateurs W1, W2 ; et
- un module de filtre sortant 6 connecté au module de commutateur 5, et configuré pour être connecté à la batterie de traction B.As can be seen in the attached figure, the on-board charger OBC comprises, from the connection end to the source S, to the connection end to the battery B:
- an incoming filter module 1 or incoming filter;
- a PFC type power correction module 2, known per se;
- a DC-Link type capacitor module 3, known per se;
- a transformer module 4 connected to the capacitor module 3, having a primary T1 and a secondary T2;
- a switch module 5 connected to the transformer module 4, which includes two switches W1, W2; And
- an outgoing filter module 6 connected to the switch module 5, and configured to be connected to the traction battery B.
Le module de filtre sortant 6 comprend un sous-module de stimulation (ou « boost » en langue anglaise).The outgoing filter module 6 includes a stimulation submodule (or “boost” in English).
En outre, les commutateurs W1, W2, sont configurés pour alimenter un point milieu du secondaire T2 du module de transformateur 4.In addition, the switches W1, W2 are configured to supply a midpoint of the secondary T2 of the transformer module 4.
Le secondaire est bi-directionnel et connecté à deux demi-ponts de MOSFET M1, M2 de sorte à réaliser un redressement de tension. Chaque demi-pont de MOSFET M1, M2 coopère avec au moins une inductance I1, I2, et est configuré pour fonctionner en décalage de phase par rapport à l’autre demi-pont M2, M1 de sorte à ne pas saturer le module de transformateur 4.The secondary is bi-directional and connected to two MOSFET half-bridges M1, M2 so as to achieve voltage rectification. Each MOSFET half-bridge M1, M2 cooperates with at least one inductor I1, I2, and is configured to operate in phase shift relative to the other half-bridge M2, M1 so as not to saturate the transformer module 4.
Plus précisément, le système de recharge rapide comprend un chargeur embarqué OBC, une batterie B, de deux commutateurs W1, W2. Il comprend en outre une borne de recharge rapide externe S pouvant être par exemple alternativement à 400V ou à 800V.More precisely, the fast charging system includes an on-board charger OBC, a battery B, two switches W1, W2. It also includes an external fast charging terminal S which can, for example, be alternatively at 400V or 800V.
Le chargeur embarqué OBC comprend un correcteur de puissance de type PFC, d’un condensateur DC LINK 3, du primaire d’un convertisseur isolé 4 lui-même comprenant un transformateur dont le point milieu du secondaire est accessible.The OBC on-board charger includes a PFC type power corrector, a DC LINK capacitor 3, the primary of an isolated converter 4 itself comprising a transformer whose midpoint of the secondary is accessible.
Le chargeur embarqué OBC est relié via un socle BEPR à une borne de recharge rapide S, plus précisément aux bornes du courant continu DC.The OBC on-board charger is connected via a BEPR base to a fast charging terminal S, more precisely to the DC direct current terminals.
Les commutateurs du sélecteur sont fermés. Le correcteur de puissance 2 (ou « PFC » pour power factor corrector en langue anglaise) est donc alimenté par la borne à 400V ainsi que le condenseur 3 de type DC LINK à la tension de la borne de recharge (400V ou 800V).The selector switches are closed. The power corrector 2 (or “PFC” for power factor corrector in English) is therefore powered by the 400V terminal as well as the DC LINK type condenser 3 at the voltage of the charging terminal (400V or 800V).
Les commutateurs W1 et W2 sont fermés et ainsi le point milieu du secondaire du transformateur est aussi alimenté par la station de charge 400V.Switches W1 and W2 are closed and thus the middle point of the transformer secondary is also supplied by the 400V charging station.
Chaque inductance associée à chaque demi-pont constitue une structure stimulation (ou « boost » en langue anglaise). On a ainsi deux stimulations en parallèle qui doivent absolument fonctionner en opposition de phase pour ne pas saturer le transformateur.
Each inductance associated with each half-bridge constitutes a stimulation structure (or “boost” in English). We thus have two stimulations in parallel which must absolutely operate in phase opposition so as not to saturate the transformer.
