SIMULATING BATTERY DYNAMICS WITH EQUIVALENT CIRCUIT MODELS
This abstract first appeared for US patent application 20250102582 titled 'SIMULATING BATTERY DYNAMICS WITH EQUIVALENT CIRCUIT MODELS
Original Abstract Submitted
examples relate to a battery management system with an enhanced equivalent circuit model (ecm) for electric vehicles, including electric vertical takeoff and landing (evtol) aircraft. the system includes a memory to store an equivalent circuit model (ecm) configured to dynamically adjust a series resistance component in real-time based on operational data from a lithium-ion battery. this adjustment models lithium depletion effects under high discharge conditions. at least one processor is configured to continuously refine parameters of the ecm by analyzing discrepancies between predicted and actual battery performance, where the adjustments are based on real-time changes in state of charge, temperature, and current.
