Controlled laboratory tests are conducted to evaluate the effects of selected electric-vehicle application factors on the performance and life of lead-acid batteries. These factors include simulated driving profiles with different levels of peak power demands for vehicle acceleration, long rest times after charge or discharge, and different methods of recharging. The performance and life variations among cells and modules in a full-scale battery pack are also examined. The analyses show that the most significant factors causing the performance variations and degradation are the levels of peak power demand by driving profile and the cell location within each six-cell module.
