Battery relaxation refers to the natural voltage stabilization process that occurs after a battery has been charged or discharged and is then left at rest (i.e., no current flows in or out). During this period, the battery’s terminal voltage gradually settles toward its equilibrium value, reflecting the internal electrochemical balance.
Importance of Battery Relaxation:
Used in State of Charge (SOC) and State of Health (SOH) estimation in Battery Management Systems (BMS).
Helps engineers assess battery characteristics, such as open-circuit voltage (OCV) and internal resistance.
Studied in battery modeling and diagnostics to better understand aging and performance degradation.
Relevant for resting intervals in charging protocols to improve measurement accuracy or prolong battery life.
