Afin de résoudre le problème susmentionné, un système de stockage d'énergie est caractérisé en ce qu'il comprend : une plaque chargée qui est chargée avec des charges électriques en raison de la différence de potentiel entre la position installée de la plaque chargée et un point de mise à la terre ; un condensateur qui est connecté électriquement à la plaque chargée, et qui se déplace et accumule les charges électriques chargées sur la plaque chargée ; des commutateurs disposés entre la plaque chargée et le condensateur, et conçus de manière à être capable de couper la connexion électrique entre la plaque chargée et le condensateur ; une unité de calcul de tension de plaque qui détermine la tension de la plaque chargée, ou la quantité de charges électriques chargées sur la plaque chargée ; et une unité de commande qui met en oeuvre la commande d'ouverture/fermeture des commutateurs en fonction de la tension de la plaque chargée ou de la quantité de charges électriques chargées sur la plaque chargée déterminée par l'unité de calcul de tension de la plaque, et déplace les charges électriques chargées sur la plaque chargée au condensateur.
