Round-Trip Energy Efficiency and Energy-Efficiency Fade Estimation for Battery Passport

2023 IEEE Vehicle Power and Propulsion Conference (VPPC), 2023
The battery passport is proposed as a method to make the use and remaining value of batteries more transparent. The future EU Battery Directive requests this passport to contain the round-trip energy efficiency and its fade. In this paper, an algorithm is presented and demonstrated that estimates the round-trip energy efficiency of a battery pack.
