step S6: and after the acid injection timing is finished, closing the acid injection valve and the battery vacuumizing valve, separating the acid injection gun head from the battery, and opening the battery pressure release valve and the acid discharge valve to discharge redundant acid in the battery to the acid discharge groove.
