It consists of a current and/or voltage regulator 1 connected to batteries by way of relays 2 controlled by analog gates 3, themselves enabled by a counter 4 incremented by an "AND" gate 5 whose inputs receive, on the one hand, the signal from a low frequency clock 6, and on the other hand, the signal from a voltage comparator 7 fixing the "switchover" threshold on the basis of the state of charge of the connected battery 8 marked out with the aid of the lamp 9. The device according to the invention is particularly suited to the use of photovoltaic sensors whose power is limited.

Description

DESCRIPTION
La présente invention concerne un dispositif électronique de gestion automatique de charges de batterie permettant, en utilisant un régulateur de puissance limitée de charger plusieurs batteries d'acoumulateurs par basculement automatique d'une batterie à l'autre après contrôle automatique du niveau de charge. Il comporte un système de signalisation de la batterie en cours de charge et un système permettant de connaître la ou les batteries déjà chargées.DESCRIPTION
The present invention relates to an electronic device for automatic management of battery charges making it possible, using a limited power regulator, to charge several accumulator batteries by automatic switching from one battery to another after automatic control of the charge level. It includes a signaling system for the battery being charged and a system enabling the battery or batteries already charged to be known.

Les systèmes existants permettent en général la charge d'une seule batterie ou de plusieurs batteries en parallèle ce qui impose un dimensionnement du régulateur dépendant du nombre maximum de batteries qui se trouve de ce fait limité. Par ailleurs, dans le cas de plusieurs batteries le contr8le du niveau de charge de chacune des batteries n'est pas assuré. Existing systems generally allow the charging of a single battery or of several batteries in parallel, which means that the regulator must be dimensioned depending on the maximum number of batteries, which is therefore limited. Furthermore, in the case of several batteries, the control of the charge level of each of the batteries is not ensured.

Le dispositif selon l'invention permet de remédier à l'ensemble de ces inconvénients. The device according to the invention overcomes all of these drawbacks.

Il comporte en effet . un système séquentiel autorisant le branchement d'une seule batterie à la fois au
régulateur dont le dimensionnement ne dépend que de la puissance nécessaire à la
charge de cette seule batterie. te nombre de batteries connectées au système n'est
de ce fait pas limité.It does indeed. a sequential system authorizing the connection of only one battery at a time to the
regulator whose dimensioning depends only on the power necessary for the
charge of this single battery. The number of batteries connected to the system is
therefore not limited.

. un système de contrale qui assure le mamie niveau de charge à chacune des batteries
quelque soit leur nombre.. a control system which ensures the level of charge for each of the batteries
whatever their number.

. une signalisation de la batterie en charge. . signaling of the battery in charge.

. un système à commutation manuelle permettant de repérer les batteries déjà chargées. . a manual switching system for identifying already charged batteries.

La figure unique représente le dispositif selon l'invention. The single figure shows the device according to the invention.

Le dispositif représenté sur la figure unique comporte un régulateur de tension et (ou) de courant relié à un ensemble de relais (2) comportant chacun deux contacts "Repos travail" connectés aux batteries à charger (8), aux lampes de signalisation (9),à un comparateur (7) et à un commutateur (12). Ce commutateur permet de connecter chaque batterie à un comparateur (10) qui, après comparaison de la tension batterie à une tension de référence déclanche l'allumage d'une lampe signalant que cette batterie est correctement chargée. The device shown in the single figure comprises a voltage and / or current regulator connected to a set of relays (2) each comprising two "work rest" contacts connected to the batteries to be charged (8), to the signal lamps (9 ), a comparator (7) and a switch (12). This switch makes it possible to connect each battery to a comparator (10) which, after comparison of the battery voltage with a reference voltage triggers the lighting of a lamp signaling that this battery is correctly charged.

Les relais (2) sont commandés séquentiellement par des portes analogiques (3) lesquelles sont validées par un compteur (4) lui-même incrémenté par une porte "ET" (5) dont les deux entrées reçoivent d'une part le signal d'une horloge (6) basse fréquence de l'ordre du Hz, d'autre part le signal d'un comparateur de tension (7) fixant le seuil à partir duquel la batterie en charge sera déconnectée et le régulateur branché à une autre batterie.  The relays (2) are controlled sequentially by analog gates (3) which are validated by a counter (4) itself incremented by an "AND" gate (5) whose two inputs receive the signal of a low frequency clock (6) of the order of Hz, on the other hand the signal from a voltage comparator (7) setting the threshold from which the battery on charge will be disconnected and the regulator connected to another battery.

Le nombre de sorties du compteur (4) correspond au nombre de batteries. The number of counter outputs (4) corresponds to the number of batteries.

Dans la figure unique représentant le dispositif selon l'invention ce nombre a été limité à quatre mais peut être étendu sans restriction.In the single figure representing the device according to the invention, this number has been limited to four but can be extended without restriction.

Le compteur (4) permet, à travers les portes analogiqles (3) d'alimenter les relais (2) en activant les transistors dans un ordre préétabli de TI a T4 puis retour à TI et ainsi de suite. Pour ce faire, il valide les portes analogiques (3) dans le même ordre. The counter (4) allows, through the analog doors (3) to supply the relays (2) by activating the transistors in a pre-established order from TI to T4 then return to TI and so on. To do this, it validates the analog gates (3) in the same order.

Lorsque T1 est activé, le relais qui lui est associé passe du "Repos" au "Travail" et la tension de la batterie correspondante (+ bat.) est testée par le comparateur (7) à travers le premier contact "travail" du relais. When T1 is activated, the associated relay switches from "Rest" to "Work" and the corresponding battery voltage (+ bat.) Is tested by the comparator (7) through the first "work" contact of the relay .

Toutes les autres batteries restent déconnectées du fait que leur relais respectivement associé reste au "Repos". All the other batteries remain disconnected due to the fact that their respective associated relay remains at "Rest".

Dans le cas où la batterie associée au transistor T1 est déchargée, le comparateur (7) constate une tension batterie (+ bat.) inférieure à une tension de référence fixée par le potentiomètre PI et n1 émet aucun signal en direction de la porte " ' (5). Celle-ci, ne recevant que le signal de l'horloge basse fréquence (6) ne permet pas l'incrémentation du compteur (4) et les choses restent en l'état : le relais associé au transistor T1 reste collé et la batterie correspondante, reliée au régulateur à travers la diode D5 et le premier contact "Travail" de ce relais, se charge.De plus, la lampe (9) associée s'allume à travers le deuxième contact "Travail" du relais signalant la batterie en charge. In the case where the battery associated with the transistor T1 is discharged, the comparator (7) finds a battery voltage (+ bat.) Lower than a reference voltage fixed by the potentiometer PI and n1 emits no signal in the direction of the door "' (5). This one, receiving only the signal of the low frequency clock (6) does not allow the incrementation of the counter (4) and things remain as they are: the relay associated with the transistor T1 remains glued and the corresponding battery, connected to the regulator through diode D5 and the first "Work" contact of this relay, is charged. In addition, the associated lamp (9) lights up through the second "Work" contact of the signaling relay the battery in charge.

Dans le cas oa la batterie associée au transistor T1 est déji chargée, le comparateur (7) constatant que la tension batterie (+ bat) est égale - à la tension de référence,envoie un signal à l'entrée de la porte "ET" (5). Ce signal associé à celui de l'horloge basse fréquence (6), permet d'incrémenter le compteur (4) qui valide alors la porte analogique (3) correspondant au transistor T2 . Le transistor T1 est déconnecté et le transistor T2 est activé. Le relais associé au transistor T2 passe au "travail".  In the case where the battery associated with transistor T1 is already charged, the comparator (7) noting that the battery voltage (+ bat) is equal - to the reference voltage, sends a signal to the input of the "AND" gate (5). This signal associated with that of the low frequency clock (6), makes it possible to increment the counter (4) which then validates the analog gate (3) corresponding to the transistor T2. The transistor T1 is disconnected and the transistor T2 is activated. The relay associated with transistor T2 goes to "work".

La batterie associée au transistor T2 est testée à son tour et le processus recommence. The battery associated with transistor T2 is tested in turn and the process begins again.

L'absance de batterie dans la chaine est prise en compte par le dispositif comme une batterie chargée et le basculement est automatique vers la batterie suivante. The battery absence in the chain is taken into account by the device as a charged battery and the switchover is automatic to the next battery.

Lorsque toutes les batteries sont chargées le dispositif passe sans arrêt d'une batterie à l'autre et assure de la sorte une charge d'entretien sans surcharge.  When all of the batteries are charged, the device continuously switches from one battery to another, thereby ensuring a maintenance charge without overcharging.

les batteries pouvant être mises en charge ou retirées dans n'importe quel ordre, un dispositif annexe,commutateur (12), comparateur (10) et lampe de signalisation (il), permet de repérer les batteries déà chargées. L'ensemble, comparateur (10) et lampe de signalisation (11), peut être remplacé par un appareil de mesure de tension. the batteries being able to be charged or removed in any order, an additional device, switch (12), comparator (10) and signaling lamp (II), makes it possible to locate the de-charged batteries. The assembly, comparator (10) and signaling lamp (11) can be replaced by a voltage measuring device.

Chaque batterie (8) est reliée au commutateur manuel (12) à travers un contact "Repos" du relais qui lui est associé. Le commutateur a un nombre de positions égal au nombre de batteries. La lampe (11) ne s'allume que lorsqu'une batterie correctement chargée est sélectionnée. La tension de la batterie sélectionnée est comparée à une tension de référence par le comparateur (10) qui active le transistor (T5) lorsque la tension de la batterie est correcte. Le transistor (T5) en devenant conducteur permet l'allumage de la lampe (1i). Dans le cas contraire le transistor
T5 reste bloqué et la lampe (11) reste éteinte.Each battery (8) is connected to the manual switch (12) through a "Rest" contact of the relay associated with it. The switch has a number of positions equal to the number of batteries. The lamp (11) only lights up when a properly charged battery is selected. The voltage of the selected battery is compared to a reference voltage by the comparator (10) which activates the transistor (T5) when the battery voltage is correct. The transistor (T5) becoming conductive allows the ignition of the lamp (1i). Otherwise the transistor
T5 remains blocked and the lamp (11) remains off.

Le dispositif selon l'invention est particulièrement adapté aux modules photovoltalques.  The device according to the invention is particularly suitable for photovoltaic modules.
