To achieve energy savings in the transportation sector, the Korean government has been implementing various policies promoting the widespread adoption of eco-friendly vehicles. Fuel cell electric buses are recognized as an effective alternative due to their environmental friendliness and potential for alternative energy utilization. Currently, the energy efficiency of fuel cell electric buses is measured under real-road conditions. Outdoor measurements are influenced by weather factors, such as external temperature, wind direction, and wind speed, leading to low accuracy and challenges in achieving repeatability and reproducibility. This study aims to investigate the applicability of an indoor measurement method conducted on the chassis dynamometer to improve the current outdoor measurement method for assessing the energy consumption efficiency of fuel cell electric buses. The goal is to enhance the accuracy and reliability of the results. This research applied the temperature/pressure method to measure the energy efficiency of fuel cell electric buses. Twenty tests were conducted under different conditions, including variations in vehicle weight(i.e., curb weight, laden weight) and driving modes(i.e., KS R 1135 constant-speed driving, K-WHVC driving mode). The test results revealed that, among the tested conditions, the laden weight combined with the K-WHVC mode exhibited the highest validity for applying the indoor measurement method to assess the energy efficiency of fuel cell electric buses.
