Abstract
Methods of detecting anomalies in and/or overcharge protection for secondary (rechargeable) electrochemical units, such as secondary cells and multicell secondary batteries. In some embodiments, the methods are based on a health measure referred to as “reverse coulombic efficiency” (RCE), which is based on a principle that the maximum amount of charge added to a secondary electrochemical unit during recharging should equal a net amount of charge discharged from the secondary electrochemical unit since a most recent fully charged state. An RCE-based health measure can be used to predict anomalies in secondary electrochemical units that can lead, for example, to overheating, explosion, and underperformance, among other things. Apparatuses and systems for implementing RCE-based anomaly detection and/or overcharge protection are also disclosed.
