Development of an extended-range electric vehicle: a systems engineering approach

This report presents the complete design (i.e., from product level to implementation level) of a sportive hatchback extended-range electric vehicle, including the design rationales and product creation process used. The project had two main goals: First, the development of a modular extended-range electric vehicle concept demonstrator; Second, the development of an electric vehicle powertrain development platform. It was concluded that it is feasible to meet the requirements, but that additional engineering effort is required beyond this project

Micro spectrometer for the measurement of the composition of new gas

As the world is in need of more sustainable energy sources, the use of new gases like hydrogen or bio-gases seems to be a very attractive one. By mixing these new gases with the traditional natural gas, it becomes possible to have a smooth and economically durable transition. The amount of new gases added may be dependent on the availability, progress of technology and safety and regulatory issues. This is very much like what is already been done with electrical energy sources like wind or solar power. However, unlike electricity, gas comes in a wide variety. Unfortunately appliances and machines currently running on gas are designed to operate only within a very strict window of gas compositions. To be able to widen this band, it is required to have machines that can adapt, depending on the available gas composition. It is therefore required to be able to measure this composition. This thesis describes the first steps in the design and development of an infrared absorption multi-gas micro-spectrometer for the measurement of the concentrations of Carbon Monooxide, Carbon Dioxide and Hydro Carbons in a composite gas. This includes mathematical modeling, design and fabrication. From the model it is found that it should be possible to design a system which is capable of detecting all these gases with sufficient accuracy and over their total dynamic range. Test structures have been designed and partly fabricated, giving great insight in the limitations, restrictions and tolerances of the fabrication process.Electronic Instrumentation LaboratoryMicroelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc

InMotion hybrid racecar : F1 performance with LeMans endurance

Purpose : – The purpose of this paper is to demonstrate that using advanced powertrain technologies can help outperform the state of the art in F1 and LeMans motor racing. By a careful choice and sizing of powertrain components coupled with an optimal energy management strategy, the conflicting requirements of high-performance and high-energy savings can be achieved. Design/methodology/approach : – Five main steps were performed. First, definition of requirements: basic performance requirements were defined based on research on the capabilities of Formula 1 race cars. Second, drive cycle generation: a drive cycle was created using these performance requirements as well as other necessary inputs such as the track layout of Circuit de la Sarthe, the drag coefficient, the tire specifications, and the mass of the vehicle. Third, selection of technology: the drive cycle was used to model the power requirements from the powertrain components of the series-hybrid topology. Fourth, lap time sensitivity analysis: the impact of certain design decisions on lap time was determined by the lap time sensitivity analysis. Fifth, modeling and optimization: the design involved building the optimal energy management strategy and comparing the performance of different powertrain component sizings. Findings : – Five different powertrain configurations were presented, and several tradeoffs between lap time and different parameters were discussed. The results showed that the fastest achievable lap time using the proposed configurations was 3¿min 9¿s. It was concluded that several car and component parameters have to be improved to decrease this lap time to the required 2¿min 45¿s, which is required to outperform F1 on LeMans. Originality/value : – This research shows the capabilities of advanced hybrid powertrain components and energy management strategies in motorsports, both in terms of performance and energy savings. The important factors affecting the performance of such a hybrid race car have been highlighted

InMotion: Hybrid race car, beating F1 at LeMans

This paper presents the design of a hybrid electric powertrain for the InMotion IM01 race car. InMotion is a multidisciplinary project group of experienced master students, PhD students, and professors from Eindhoven University of Technology (TU/e). The authors of this paper were involved in the project to develop a suitable powertrain architecture for use in the IM01 series hybrid race car. The most important requirements were to achieve a lap time of below 2 min 45 s on the Circuit de la Sarthe, and to have a durability, efficiency, cornering speed, and acceleration that exceeds Formula 1 race cars. Data provided from InMotion included design restrictions, a simplified drive cycle, and technical data of some components. This data was analyzed and the required powertrain component sizes were determined. A detailed drive cycle calculation and sensitivity analysis were introduced to find the variables that significantly influence the lap time. The powertrain was modeled using the backwards approach and an energy management strategy was designed with the objective of minimizing fuel consumption. Finally, five different powertrain configurations were presented, and several tradeoffs between lap time and different parameters were discussed. The results showed that the fastest achievable lap time using the proposed configurations was 3 min 9 s. It was concluded that several car and component parameters have to be improved to decrease this lap time to the required 2 min 45 s. Recommendations for future work to achieve this were addressed
