Abstract

Selon un mode de réalisation, l'invention concerne un dispositif de gestion de cellules de stockage qui est pourvu d'une pluralité de dispositifs à cellules de stockage et d'une pluralité de dispositifs d'ajustement d'énergie électrique correspondant à chacun des dispositifs à cellules de stockage. La température d'un dispositif à cellules de stockage est entrée dans une unité d'entrée de température par l'intermédiaire des dispositifs d'ajustement d'énergie électrique. Une unité de sélection sélectionne, sur la base de la température du dispositif à cellules de stockage entrée, le dispositif d'ajustement d'énergie électrique commandant le dispositif à cellules de stockage qui doit effectuer une charge/décharge en tant que dispositif d'ajustement d'énergie électrique faisant l'objet d'une instruction de charge/décharge pour provoquer une charge/décharge. Une unité de distribution distribue une valeur d'instruction de charge/décharge au dispositif d'ajustement d'énergie électrique, qui fait l'objet de l'instruction de charge/décharge, sélectionné sur la base du résultat de la sélection par l'unité de sélection. Par conséquent, le développement du système est facilité et la charge/décharge d'énergie électrique peut être répartie d'une manière appropriée.
