Numerical methods investigate grid configuration and deformation effects on VRLA-batteries, suggesting optimizations.
In this study, numerical methods were employed to investigate the effect of grid configuration, lug position, and wire angles on the stress-deformed state of double rectangular and diagonal grids made of Pb–0.7%Sn–0.08%Ca alloy for VRLA-batteries. The maximum values of stress and displacement were calculated using SolidWorks and ANSYS programs of finite element analysis. The recommendations were given to optimize design and prevent deformation and distortion of the double grids after solidification, which were confirmed in production conditions.
