Unraveling Battery Relaxation: A Deep Dive into Voltage Dynamics

In our most recent scholarly endeavor, we partnered with the esteemed Matthieu Dubarry to unravel the multifaceted nature of battery relaxation. Our comprehensive exploration ventured into the relaxation patterns observed in commercial LFP and NMC811 cells.

Far from being a passive phase, it emerges as a dynamic interplay governed by many variables:

• Time: The duration the battery has been in a charged or discharged state.
• Cell Chemistry: The specific chemical composition and structure of the battery cell.
• C-Rate: The rate in dependency of the current at which the battery is charged or discharged.
• Depth of Discharge (DoD): The extent to which the battery is depleted.
• Current Flow Direction: The direction in which the current is flowing—whether charging or discharging.
• Temperature: The operational temperature of the battery.
• Age: The lifespan and the number of charge-discharge cycles the battery has undergone.
