Some Critical Thinking on EV Battery Reliability: from Enhancement to Optimization -- comprehensive perspectives, lifecycle innovation, system cognation, and strategic insights

Abstract: In the era of sustainable transportation, the significance of electric vehicles (EVs) and their battery technology is becoming increasingly paramount. This study addresses the critical aspect of EV battery reliability, an essential factor in the vehicles' sustainability, performance, and longevity. Current efforts to enhance EV battery reliability tend to focus on isolated areas, often missing the broader, interconnected challenges within the system. This research investigates these challenges across micro, meso, and macro levels, presenting a novel lifecycle framework that includes "Zero"-Life reliability and phases such as use, reuse, repurpose, and recycling. By adopting a holistic approach and delving into system cognition, the study aims to bridge the gap between isolated improvements and comprehensive system optimization, aligning with global sustainability goals and contributing to the advancement of sustainable transportation and EV technology.
