Current distribution in lead/acid and nickel/cadmium accumulators

A simple method of determining the current distribution in accumulators which keeps the measuring and computational requirements within practical limits is briefly described. The local maximum and minimum loading conditions within the battery can be obtained with satisfactory accuracy. The current distributions in different types of lead/acid and nickel/cadmium accumulator were investigated. It depends on a number of parameters; discharge current, state-of-discharge, construction type, type of system and temperature. These were investigated and the result discussed. We also highlighted the differences encountered in the behaviour of the current distribution in lead/acid and alkaline accumulators.
