The increasing adoption of battery electric vehicles (BEVs), driven by the EU's target of no internal combustion engine vehicles from 2035 onwards, is driving significant changes in the automotive industry. However, the high degree of electrification and the unique low-speed acceleration behavior of BEVs therefore lead to new challenges. Measuring the drivetrain power and efficiency in a reproducible way and obtaining meaningful results is one of the challenges.To address this challenge, a novel test method is developed that offers a simple and preferably modification-free approach to drivetrain power and efficiency measurements for BEVs, allowing for efficient and reproducible testing. Different paths for determining the drivetrain power with varied measurement efforts are presented and evaluated. The test method is designed to provide reliable and accurate results for BEVs.In this study, the effectiveness of the test method is shown by presenting the results of tests conducted with a VW e-up! on a Vehicle-in-the-Loop test bench and comparing them with data from previous studies. The results show that this approach offers a reproducible and meaningful way to measure power and efficiency in BEV’s drivetrains.In addition to the discussion of the results, insights into the measurement of BEV’s drivetrains are given. An outlook on future challenges and how to overcome these with the help of the presented test bench as well as the knowledge gained from the study completes the paper.Overall, the study offers insights into the development and testing of BEVs, providing a robust and reliable test method.
