Abstract
Over recent years, the number of battery electric vehicles (BEVs) has drastically increased due to new European Union (EU) regulations. These regulations force vehicle manufacturers to adjust their product range in order to fulfill the imposed carbon dioxide limits. Such an adjustment enforces the usage of battery electric vehicles. However, research into the optimal BEV architectures and topologies is still in progress. Therefore, the aim of this paper is an analysis of all the current electric vehicle topologies. From this analysis, the authors identify different basic battery shapes. Subsequently, these shapes are used to describe the impact of the battery on the passenger compartment. As an initial result of this analysis, the authors create a new denomination method, via which it is possible to cluster the battery topologies. In a second step, the collected data is clustered using the novel denomination method. Finally, this paper presents the benchmark topologies for the analyzed segments.
Highlights
IntroductionThis tendency is mostly due to the European Union (EU) CO2 emission standards for passenger vehicles
In order to comply with the imposed limits, manufacturers can add battery electric vehicles (BEVs) or plug-in hybrid electric vehicles (PHEVs) to their fleet
A topology analysis based on the denomination methods is conducted
Summary
This tendency is mostly due to the EU CO2 emission standards for passenger vehicles. These regulations define CO2 targets for each manufacturer according to the average weight of their fleet [2]. While BEVs provide a solution to meet these targets, they present a major challenge when it comes to defining their architecture and topology
