Abstract

See full text

A method, apparatus, and control system for a battery cell include a heat exchanger in thermal contact with the battery cell, and a first controller. The first controller connects to the heat exchanger, and monitors the battery cell. The first controller includes a reduced order electrochemical model, a heat generation model, and a heat generation controller. The first controller determines a target parameter for the battery cell, and determines battery cell parameters. The reduced order electrochemical model determines internal ROM variables based upon the battery cell parameters. The heat generation model determines an electrochemical heat generation parameter from the battery cell based upon the internal ROM variables and the target parameter for the battery cell. The heat generation controller determines a heat work parameter based upon the electrochemical heat generation and the target parameter for the battery cell. The heat exchanger is controlled based upon the heat work parameter.
