Abstract

Le dispositif de l'invention se rapporte au domaine de l'électrotechnique et peut être utilisé lors de la production de batteries haute tension d'accumulateurs d'énergie électrique à des fins de transport ou d'alimentation électrique. Selon la solution technique, une unité d'équilibrage de chaque accumulateur comprend deux convertisseurs CC/CC distincts dédiés, à savoir : un convertisseur de faible puissance de retour fonctionnant en mode de limitation de puissance afin de transmettre de l'énergie depuis l'accumulateur vers la ligne d'échange électrique de courant continu, et un convertisseur de tension de puissance direct ayant un coefficient de transmission de tension fixe rigide (transformation) afin de transmettre l'énergie depuis la ligne vers l'accumulateur. Le résultat technique de l'invention est que, grâce l'utilisation d'un convertisseur direct plus puissant, il est possible de commander un courant soutenu important vers un accumulateur voulu depuis la ligne de courant continu isolée d'échange électrique, l'énergie étant envoyée dans celle-ci par un grand nombre d'accumulateurs « donneurs » à l'aide de convertisseurs retour de moindre puissance, ce qui permet pour un temps de décharge limité de compenser non seulement le fuites mais aussi le déficit de charge dans plusieurs accumulateurs parmi les « pires ».
