Charging device for accumulators and method for determining a stratification of electrolyte with different acid density and / or of sulfate fractions in the active material of the positive plates in accumulators

摘要

A method for determining a stratification of electrolyte with different acid density and / or of sulfate fractions in the active mass of the positive electrode plates in batteries (2) has the steps: DOLLAR A a) determining the course of the charging current that occurs when charging the battery (2) ( I¶L¶) and / or the charging voltage (U¶L¶); DOLLAR A b) Detection of a stratification from an increased charging current consumption compared to a similar accumulator (2) without stratification with a fixed charging voltage curve or reduced charging voltage with a fixed charging current curve.
