“…Some technical parameters of cars in this segment are limited, e.g., number of passenger seats must not exceed 8, but have no further requirements regarding, e.g., mass, maximum speed (minimum speed is 25 km/h), or measurements. Even though there are differences between the M1 category and L7e such as the maximum mass, required crash tests, and width, some vehicles that fulfill requirements of both categories can be registered as either M1 or L7e [8,11,12].…”

Small electric vehicles (SEVs) have the potential to contribute to climate protection, efficient land use, and mitigation of air pollution in cities. Even though, they show many benefits that could enhance urban quality of life, they are not yet widely used. In this paper, benefits as well as drawbacks for these vehicles are discussed by combining literature research and outcomes of a mixed-method approach with expert interviews and an online survey. Resulting from these arguments, a vision for SEVs in urban areas is drawn showing them integrated in a mix of various transport modes. Environmental benefits are derived, for example, from their lower weight and low maximum speed making them a more energy-efficient transport option than heavier cars. Additionally, the small vehicle size lowers land use for SEVs and, e.g., allows for less parking areas needed. However, they also hold constraints that need to be dealt with in different ways. On the one hand, the lower safety compared to passenger cars is an issue that is further worsened by current traffic regulations. On the other hand, costs in terms of purchase prices seem to be an issue for SEVs.

“…Besides the round cells, pouch cells and prismatic cells are available on the market. The pouch cell design is considered the most suitable for the race car application, as they have a very high energy density and a large surface area for the cooling of the cells [22]. Furthermore, these cells are available with high C-rates on the market and with the appropriate approvals (e.g., CE labeling).…”

Today, design engineers engaged in the development of a high-performance electrical drive-train are challenged by the multitude of possible topological choices and numerous mutually interconnected physical phenomena. Development teams around the globe struggle with this challenge; usually they employ several tools for simulation and topology optimization and transfer multiple versions of their product models in a mainly manual process. The research presented in this paper aims to explore a holistic possibility to realize a sensible analysis-synthesis cycle that takes into consideration current developments in design, simulation and optimization processes. This kind of process can enhance the transparency of design decisions, can reduce the risk of design and process flaws and can support the approach toward a holistic optimum. The investigation starts with the development of the topological concept of the drive-train and continues over the interconnected simulation of several decisive properties of the drive-train. Obviously, these properties concern several domains (mechanical, electrical, thermal and the control domain). The optimization of the drive-train takes into consideration the main requirement—in the investigated example, which is a formula student drive-train—the lap time. The result is a holistic concept for a design, simulation and optimization approach that considers topological variety, interconnected multi-domain simulation and a continuous connection to the decisive requirements.

ZusammenfassungRegulatorische Vorgaben dienen sowohl der Nutzergruppe als auch dem produzierenden Unternehmen. Da zum Erfolg der Elektromobilität die breite Akzeptanz in der Gesellschaft essenziell ist, schaffen gesetzliche Anforderungen einen Rahmen, um die Funktionalität, die Kompatibilität und die Sicherheit des Produktes zu gewährleisten. Gleichzeitig wird den Unternehmen durch Marktharmonisierung und Konformitätsvorgaben der Rahmen zur erfolgreichen Teilhabe an der Elektromobilität vorgegeben. Diese sind entsprechend verpflichtet, einen Nachweis gegenüber Technischen Prüfstellen und Diensten zu erbringen. Je nach Fahrzeugklasse und Zulassungsart können die Vorgaben variieren. Dabei gilt es, verschiedene Normen und Standards zu erfüllen, die aus dem unabdingbaren, interdisziplinären Austausch zwischen den Domänen Automobiltechnik, Elektro- und Energietechnik sowie Informations- und Kommunikationstechnik hervorgehen. Durch elektromobilitätsspezifische Systemkomponenten und der Hochvolt-Spannungsebene im Fahrzeug legen die Vorschriften ein besonderes Augenmerk auf deren sicherheitstechnische Erfüllung. Bekannte Themenfelder – etwa wie Noise, Vibration und Harshness (NVH) oder die elektromagnetische Verträglichkeit (EMV) – stellen die Entwicklungsabteilungen aufgrund der „lautlosen“ Elektromobilität und der hohen Spannungsebene vor Herausforderungen. Neben den Regelungen auf Gesamtfahrzeugebene liegt in der Elektromobilität der Fokus vor allem auf den Einzelkomponenten, beispielsweise der Antriebsbatterie oder den Hochvolt-Steckverbindungen. Insbesondere wegen der hohen Energiedichten gelten für die Antriebsbatterien strenge, länderspezifische Vorgaben, die für die Zulassung notwendig sind. Nur durch eine enge entwicklungsbegleitende Absicherung kann die Antriebsbatterie den gesetzlichen Anforderungen entsprechend auf den Markt gebracht werden.
