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…
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…
Improved Battery State Estimation Under Parameter Uncertainty Caused by Aging Using Expansion Measurements
Sravan Pannala, Puneet Valecha, Peyman Mohtat +2
Accurate tracking of the internal electrochemical states of lithium-ion battery during cycling enables advanced battery management systems to operate the battery safely and maintai…
