Patent ID: 8484834

Claim:
Improved plant for the electrochemical formation of lead-acid batteries, of the type each provided with a rigid container closed at the top by a lid and containing at least one voltaic cell, said plant comprising: at least one circuit inside which an electrolytic solution flows and which is provided with supply means for conveying into the cells of said batteries, by at least one first distribution header, a first flow of electrolytic solution at a controlled pressure, and with return means for removing under a vacuum, by at least one suction header, said first flow of electrolytic solution from said cells; a plurality of caps which can be removably mounted in a sealed manner on the lids of said batteries opposite corresponding cells, each cap comprising: at least one inlet pipe connected via a first connecting line to said first distribution header ( 9 ) for supplying a corresponding said cell with said flow of electrolytic solution; at least one outlet pipe ( 19 ) connected via a second connecting line ( 13 ) to the suction header ( 12 ) for extracting from said cell said first flow of electrolytic solution; wherein each said cap also comprises fluidic connection means ( 20 , 20 ′) which connects the internal environment of the cell, present underneath the lid, to the external environment which is at atmospheric pressure, so as to dilute the formation of inflammable gases inside said cell; wherein said fluidic connection means of each said cap connects via a third connecting line the internal environment of a cell to a second distribution header of said supply means which supply, by said second distribution header, during initial filling of the plant, said cells with a second flow of electrolytic solution greater than the first flow of electrolytic solution.
