Mathematical Model for the Design of Grids for Electric Vehicle Batteries 780221
The potential and current distribution over the grid of a lead-acid battery can be calculated by applying Kirchoff's Law to a three-dimensional resistance network analog. Such a model was used to simulate the highrate discharge of a typical grid having a conventional, uniform pattern of grid members. The potential and current density were found to vary widely over the grid surface. Modifications to the design of the grid make the potential and current density distribution more uniform, which would lead to more efficient utilization of the battery active materials, and an improved battery performance.
