REPLENISHMENT SYSTEM FOR BATTERIES

摘要

A system for replenishing liquid in a battery having a plurality of cells 10 comprises a reservoir 13 having compartments 12 equal in number to the cells 10, each compartment 12 being connected to a cell 10 by a pipe 11 having a bore which is sufficiently small to inhibit free flow from the compartments 12 to the cells 10. The pipes 11 open into the cells 10 at the desired level of electrolyte therein. A gas pressure Pa applied to the tops of the compartments 12 to urge liquid therein into the cells 10 and ultimately to compress trapped gas volumes in the cells 10. Subsequent removal of pressure Pa allows excess liquid in the cells 10 to flow back to the compartments 12 until the bottoms of the pipes 11 are uncovered.
