Re.Pulse is LG Energy Solution’s battery state-of-health (SoH) diagnostic solution, powered by an innovative pulse-based inspection mechanism. Its name reflects the idea of reviving a battery's pulse. Re.Pulse assesses used battery performance throughout its full lifecycle, whether in service or after removal. Because this system integrates seamlessly with standard chargers, it eliminates the need to remove the battery, making diagnostics significantly faster and simpler. Additionally, Re.Pulse delivers precise cell-level (bank) SoH diagnostics, moving beyond conventional pack-level monitoring. Based on assessment results, batteries are categorized into three streams: recycling, reuse, and remanufacturing, to maximize overall second-life value. In an era dominated by EVs and robotics, Re.Pulse serves as a foundational technology that minimizes battery waste and drives a sustainable battery ecosystem. This pulse-based diagnostic system supports practical decisions across diverse second-life battery applications.
