Abstract

Procédé et dispositif de surveillance de la quantité d'électrolyte d'un accumulateur. Selon l'invention on élabore un signal proportionnel au courant d'électrolyse de l'électrolyte qu'on intègre, obtenant ainsi une information proportionnelle à la quantité d'électrolyte décomposé. Application à l'utilisation des accumulateurs.
