Procedure for measuring an electrolytestratification in accumulators

摘要

Determination of stratification of electrolyte in active mass of positive electrode plates in rechargeable batteries (2) involves determining a variation of a charging current and/or a charging voltage of the rechargeable battery occurring during charging; and detecting a stratification of the electrolyte from an increased charging current consumption in the rechargeable battery as compared to an identical rechargeable battery without stratification when there is a fixed charging voltage variation or a reduced charging voltage when there is a fixed charging current variation. An independent claim is also included for charging device (1) for rechargeable batteries comprising temperature sensor (3) for measuring the battery temperature and a charge controller (4) for carrying out the electrolyte-stratification determination method.
