Parallel-Connected Battery Current Imbalance Dynamics
Andrew Weng, Sravan Pannala, Jason B. Siegel +1
In this work, we derive analytical expressions governing state-of-charge and current imbalance dynamics for two parallel-connected batteries. The model, based on equivalent circuit…
Predicting the impact of formation protocols on battery lifetime immediately after manufacturing
Andrew Weng, Peyman Mohtat, Peter M. Attia +4
Increasing the speed of battery formation can significantly lower lithium-ion battery manufacturing costs. However, adopting faster formation protocols in practical manufacturing s…
A Fast Diagnostic to Inform Screening of Discarded or Retired Batteries
Joseph A. Drallmeier, Clement Wong, Charles E. Solbrig +2
With the increased pervasiveness of Lithium-ion batteries, there is growing concern for the amount of retired batteries that will be entering the waste stream. Although these batte…
An Algorithmic Safety VEST For Li-ion Batteries During Fast Charging
Peyman Mohtat, Sravan Pannala, Valentin Sulzer +2
Fast charging of lithium-ion batteries is crucial to increase desirability for consumers and hence accelerate the adoption of electric vehicles. A major barrier to shorter charge t…
Li-ion Battery Fault Detection in Large Packs Using Force and Gas Sensors
Ting Cai, Peyman Mohtat, Anna G. Stefanopoulou +1
Internal short circuits are a leading cause of battery thermal runaway, and hence a major safety issue for electric vehicles. An internal short circuit with low resistance is calle…
Promise and Challenges of a Data-Driven Approach for Battery Lifetime Prognostics
Valentin Sulzer, Peyman Mohtat, Suhak Lee +2
Recent data-driven approaches have shown great potential in early prediction of battery cycle life by utilizing features from the discharge voltage curve. However, these studies ca…
