“…For the thermal verification of the drivetrains' components, the simulated warm‐up behaviors of the fuel cell stack, the electric engine and the hybrid battery are compared to measured data. Thereby, a high accuracy is identified . To verify the cabins' thermal behavior a simulated warm‐up and cool‐down behavior is also benchmarked to measured data.…”

“…To extend the static analyzes and to have a methodology to represent a realistic energy consumptions of different drivetrains under the same circumstances, many influences, like the driving resistance, the drivetrain efficiency, the condition of the components and the vehicle cabin during the drives as well as the initial conditions and the resulting auxiliary's load have to be considered in a similar way. Therefore, a novel approach developed by Hollweck considering the named influences is presented, explained and afterwards applied on a medium sized fuel cell electric vehicle.…”

Due to the auxiliary loads' increasing influence on the overall energy consumption of electrified vehicles, a holistic tank‐to‐wheel analysis is necessary. To do so, the impact of the auxiliary load on the energy consumption of a fuel cell electric vehicle (FCEV) drivetrain is investigated by taking different driving behaviors and three European environmental conditions (Spanish, German and Norwegian weather profiles) into account. The driving pattern is analyzed with the study ‘Mobilität in Deutschland' [1] and represented with the Artemis driving cycles [2]. To match various situations of the everyday life, realistic boundary conditions are determined by five starting times. The corresponding weather conditions are obtained and five weather profiles for every meteorological season including the ambient temperature, solar flux and humidity are considered. By using a complete FCEV simulation model, a realistic energy consumptions is simulated and the impact of different climate conditions as well as driving behaviors is investigated. As a result, a significant influence of the auxiliary load on the overall energy consumption is detected and the need to consider the overall energy demand is demonstrated.
