By examining internal resistance and relaxation voltage during pulse charging, the system detects early signs of lithium plating—well before it becomes a threat. This innovation could significantly reduce battery degradation and safety risks, and it can be easily deployed through software updates or cloud-based platforms, making it highly practical for EV manufacturers and battery management system developers.
Under lithium plating conditions, the thickness of lithium-ion batteries increased more than during standard charging, peaking during the constant voltage phase. After this point, the thickness decreased due to the reversible nature of lithium.
