“…With the compatibility matrix a set of consistent concepts will be chosen and further considered. A modular bus system simulation model has been developed and verified in a pilot project in Berlin as shown in in Ly et al (2016) which takes all relevant system and functional parameters into account. Here the model is used to determine relevant design parameters such as battery capacity,…”

Many cities have announced ambitious plans to introduce zero-emission electric bus systems. The transformation process to electric bus systems opens up a vast design space as different charging strategies, charging technologies and battery types are available. Therefore, a profound assessment strategy is necessary to find a "most suitable system solution" under given strategic and operational requirements.In this study, we present a new methodology for conceptual design of urban electric bus systems. First, the available e-bus technologies are analysed with a special focus on charging systems, battery technology and aging. Relational functional analysis is used to derive a suitable simulation model. Based on the operational requirements, an energetic simulation of the e-bus is carried out, and the required battery capacity is obtained. Subsequently, the design space is reduced by applying a qualitative costtechnology compatibility matrix taking cost and battery aging into account. The applicability of the model is shown for an exemplary realistic operational scenario to identify three most expedient concepts, which are finally validated with an in-depth analysis.

“…In the following, the vehicle simulation model with its sub-models is presented. The exhaustive description of the sub-models and their respective application can be found in Göhlich, Kunith & Ly (2014), Jefferies et al (2015) and Ly, Göhlich & Heide (2016). In Figure 12 the input and output data for the bus system simulation are shown.…”

“…The scenario with the greater energy demand is chosen as the design case. The specific layout of the battery system (number of cells in series and in parallel) is determined from total energy consumption and maximum vehicle power demand as shown in Ly et al (2016). This may result in slightly different battery capacities for each case despite identical operational requirements.…”

Many public transport authorities have a great interest in introducing zero-emission electric buses. However, the transformation process from diesel to electric bus systems opens up a vast design space which seems prohibitive for a systematic decision making process. We present a holistic design methodology to identify the 'most suitable system solution' under given strategic and operational requirements. The relevant vehicle technologies and charging systems are analysed and structured using a morphological matrix. A modular simulation model is introduced which takes technical and operational aspects into account. The model can be used to determine a feasible electric bus system. The technology selection is based on a detailed economic analysis which is conducted by means of a total cost of ownership (TCO) model. To cope with uncertainties in forecasting, a stochastic modelling of critical input parameters is applied and three different future scenarios are evaluated. The applicability of the model was verified in a pilot project in Berlin and the methodology was applied to a realistic operational scenario. Our results indicate that electric bus systems are technically feasible and can become economically competitive from the year 2025 under the conditions examined.
