Method and system for optimizing parameters of electrochemical battery model

A system for optimizing parameters of an electrochemical battery model, the system comprising:

• a memory configured to store computer-readable commands;
• and
• at least one processor configured to execute the commands,
• wherein the at least one processor executes the commands to:
• determine values of fixed parameters of the electrochemical model on the basis of cell design information of an evaluation target battery;
• determine an optimal combination of a capacitive parameter and a starting voltage parameter of the electrochemical model through a first simulation in which a first charging pattern is applied to the electrochemical model while fixing a resistance parameter of the electrochemical model to a preset value;
• and
• determine an optimal combination of the resistance parameter by changing the resistance parameter through a second simulation in which a second charging pattern is applied to the electrochemical model while the capacitive parameter and the starting voltage parameter are set to the optimal combination.
