Study on the Extensibility of Voltage-Plateau-Based Lithium Plating Detection for Electric Vehicles

Lithium plating is an undesirable side reaction in lithium-ion cells during fast charging at lower temperatures. The voltage plateau of the open-circuit (OCV) after widely used to infer onset lithium plating. differential analysis post-charge OCV has been shown yield greater insights into Li stripping characteristics. Though this method continuously evaluated for single open circuit, a battery module can have series and parallel connection cells. effectiveness scalability voltage-plateau-based technique modules presented here. study focuses on individual connection, series-parallel connection. results validate technique, yet reliability sensitivity were observed be inferior cell published previously.
