High End Lead Acid battery to Support Latest Automotive Power Train (Battery Design and Engineering for Improved Efficiency)
Lead acid batteries have been a staple in automotive application for over a century, but as modern vehicles demand higher performance, efficiency and reliability, traditional lead acid technology has struggled to keep up. High end lead acid batteries have evolved to offer better performance, longevity, and energy density. Modern vehicles have evolved significantly, incorporating start-stop systems, regenerative braking, and increased electrical loads from infotainment, safety (ADAS) and comfort features. This shift has created a demand for Enhanced flooded batteries (EFB) and Absorbent Glass Mat (AGM) batteries, which offer improved performance, durability and efficiency compared to traditional lead-acid batteries.
The changes/ transition in the modern automobile based on our own study and how it changes the requirements of the battery in terms of PSOC operation, Charge acceptance/recovery and Cycle life will be prologue of the paper. The requirements/characteristics have been incorporated in our design of ISS, EFB & AGM product range which are successfully addressing the power, performance requirements of modern vehicles. These designs have been deployed most efficiently by utilizing different plate making technologies. Comparative advantages of each of the plate making technology vis-à-vis the application substantiated with test data. The paper will conclude with a road map of product enhancement to cater future requirements.
