Abstract
Independent and comparable information about the performance of commercial electric buses is sparse. Despite the high overall powertrain efficiency of electric buses, considerable differences are found between different bus models. This paper adds a powertrain efficiency test to a previous measurement method to further advance the performance testing of heavy-duty electric vehicles in laboratory conditions. The method is applied on five commercially available battery-electric city buses and the results are assessed on a common framework. The results showed up to 28% difference on payload-specific energy consumption between highest and lowest consuming buses and noticeable disparity between specific powertrain efficiency curves.
