Abstract
The current distribution over the surface of cylindrical VRLA accumulator electrodes for hybrid electric vehicles during discharge was determined mathematically by using an equivalent electrical circuit. The dependence of the internal resistance on the current and on the charge passed was determined by measurements on an experimental cell. The results are presented in the form of 3D diagrams for different states of discharge. The effect of the configuration of the current tabs on the current distribution over the electrode surface during discharge is discussed.
