Abstract

A method of evaluating a battery cell (44) within a battery module (42) of an aircraft hybrid-electric propulsion (HEP) system (20) is provided. The HEP system (20) includes a thermal engine (22), an electric motor (24), and a propulsion unit (28). The HEP system (20) is configured to control at least one of the thermal engine (22) or the electric motor (24) to be in drive communication with propulsion unit (28). The method includes: controlling the HEP system (20) to have the battery module (42) and the battery cell (44) disposed in a rest mode; determining an open-circuit voltage (OCV) of the battery cell (44) after a settling period of time; determining an internal resistance value of the battery cell (44) using the determined OCV; and evaluating the battery cell (44) based on the determined OCV and the determined internal resistance value.
