MAHTEMATICAL MODEL FOR THE DESIGN OF GRIDS FOR ELECTRIC VEHICLE BATTERIES
The potential and current distribution over the grid of a lead-acid battery can be calculated by applying Korchoff's Law to a three-dimensional resistance network analog. Such a model was used to simulate the high-rate 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 mort uniform, which would lead to more efficient utilization of the battery active materials, and an improved battery performance.
