Abstract
An apparatus (10) for filling at least one cell of an accumulator (12) with electrolyte is described, having a vacuum pump (14) for evacuating the cell of the accumulator (12), and having a filler device (16) for introducing the electrolyte into a fill opening (32) of a cell, and having a container (18) for receiving the entire accumulator (12), the container (18) communicating with the vacuum pump (14) via a connection stub (20), so that the accumulator (12) can be put in its entirety under a vacuum, and the filler device (16) has at least one delivery line (22) for the electrolyte, which line is extended in vacuum-tight fashion into the container (18). The delivery line (22) on each end has a respective filler head (34) with an outlet stub (36), and the outlet stub (36) engages the inside of the fill opening (32) of a cell with play (FIG. 1).
