Abstract

L'invention concerne un procédé permettant de recycler des batteries usagées, plus précisément, un procédé de recyclage de batteries usagées, susceptible de revitaliser et de restaurer les fonctions d'une batterie usagée jusqu'à au moins 95% par rapport à une nouvelle batterie par le biais d'une série de procédés comprenant les étapes de diagnostic de l'aptitude au recyclage d'une batterie usagée qui est sensiblement dégradée après avoir été utilisée pendant un certain temps, de mesure de la capacité restante de la batterie usagée, d'injection d'un liquide revitalisant pour batterie et de charge de la batterie usagée. Selon le procédé de recyclage de batteries usagées, selon l'invention, l'état d'une batterie usagée est examiné sur la base de quatre valeurs mesurées de la batterie usagée, à savoir: la tension, la valeur de régime nominal, le facteur de charge virtuelle et la résistance interne, de façon à évaluer l'aptitude au recyclage de la batterie d'une manière simple mais précise. De plus, un procédé simple et pratique qui consiste à injecter le liquide revitalisant de batterie dans une batterie usagée selon l'invention, puis à charger ladite batterie usagée, permet de revitaliser et de restaurer au moins 95% de ses fonctions en comparaison à une batterie neuve. En conséquence, le grand intérêt de l'invention réside dans le fait que les batteries usagées qui, autrefois étaient considérées comme mortes et éliminées, peuvent être revitalisées et restaurées pour une nouvelle utilisation, ce qui permet de réduire la contamination environnementale ainsi que les dépenses consacrées à l'acquisition de nouvelles batteries.
