METHOD, SYSTEM, AND APPARATUS FOR BATTERY EQUIVALENT CIRCUIT MODEL PARAMETER ESTIMATION

摘要

A method, system, and apparatus for optimizing a set of equivalent circuit model parameters of a battery is disclosed. The method includes measuring and/or receiving a terminal voltage, a current, and a temperature from the battery. The measured and/or received terminal voltage, measured current, measured temperature and a current time stamp is stored in a memory. An equivalent circuit and a set of equivalent circuit model parameters is determined for the battery. A set of estimated state variables based on at least one of the equivalent circuit model parameters is calculated. The set of equivalent circuit model parameters is optimized based on at least one of the estimated state variables. The system and apparatus include components configured to implement the method.
