LEAD STORAGE BATTERY CELL ELECTROLYTE DENSITY MEASURING DEVICE AND METHOD |
摘要 |
The measurement of the charge in a lead-acid storage battery through the determination of the density of the sulfuric acid electrolyte by making two conductivity measurements of the electrolyte with the second measurement being made after a dilution or concentration of the sulfuric acid to thereby resolve an ambiguity in the conductivity-density relationship.
