Abstract

Avec l'augmentation des prix de l'énergie, il est nécessaire de produire de l'électricité à partir de sources renouvelables comme le photovoltaïque. Un point encore plus crucial est de pouvoir stocker cette électricité produite par les panneaux solaires. Ce stockage est réalisé à l'aide de batteries. Il est cependant nécessaire d'utiliser une électronique spécifique entre les panneaux photovoltaïques et les batteries. L'invention décrit un dispositif de charge d'une batterie (constituée de plusieurs cellules comme par exemple ici 5, 6, 7) réalisant en son sein la fonction d'équilibrage des tensions de ces cellules 5, 6, 7 par charge individuelle séquentielle en utilisant des relais simple inverseur électromécaniques associés à un abaisseur, le tout piloté par un microcontrôleur.With the increase in energy prices, there is a need to generate electricity from renewable sources such as photovoltaics. An even more crucial point is to be able to store this electricity produced by solar panels. This storage is carried out using batteries. However, it is necessary to use specific electronics between the photovoltaic panels and the batteries. The invention describes a device for charging a battery (consisting of several cells such as for example here 5, 6, 7) performing within it the function of balancing the voltages of these cells 5, 6, 7 by sequential individual charging. using single electromechanical change-over relays associated with a step-down, all controlled by a microcontroller.
