Optimization study of a hybrid powertrain: Optimization of the system components and energy management of a zero-emission hydrogen powered boat

The company H2 Marine Solutions has designed a zero-emission hydrogen powered boat. This boat is compared to its fossil fuel counterpart more than twice as heavy. The reason for this is that the system components that are used in the hybrid powertrain of the hydrogen powered boat are heavier. The main question of this research is: How can we...

Speed-Torque Coupled Modular Energy Management for HEVs

Fuel consumption reduction in Hybrid Electric Vehicles (HEV) powertrains has been an important area of research over the past few decades. HEV powertrains have two energy sources : fuel and battery. The important task of splitting the energy/power demand between both these sources is performed by the Energy Management Systems (EMS). There are...

A Health-Aware Control Strategy for Enhanced Performance and Extended Hybrid Powertrain Lifecycle: A benchmark of different cost functions

The urgent need for marine transportation to reduce CO2 emissions has led to considering alternative energy and storage sources. The resulting increase in the complexity of powerplant architectures led to the development of advanced control strategies to achieve energy savings. At the same time, the health status of components has been often...

Opportunity charging: A case study based on real-life public transportation scenarios

Emissions caused by regular vehicles with fossil fuels are problematic for the environment. The integration of electric vehicles in public transportation can potentially cause zero emissions. This paper will focus on the implementation of electric buses together with inductive chargers at bus stops. These chargers will charge the bus battery...

Identifying Stakeholder Perceptions of Overhead Catenary Electric Road Systems

Heavy-duty trucks (HDTs) are a significant contributor to global anthropogenic carbon emissions. In contrary to passenger cars, HDTs have to cope with decarbonization complications due to range and weight characteristics. Overhead catenary electric road systems (ERS-OC) can aid in decarbonizing this sector. Here, trucks are equipped with a...

Performance of a Single-Aisle Aircraft with Auxiliary Propulsion and Power Unit

The aviation industry has grown at a steady rate of 5% per year over the past decades and is projected to continue this growth over the coming years. In sharp contrast stands the increasing concern with the reduction of the environmental impact of flying in the short term. To this end, a fuselage boundary layer ingesting propulsor powered using...

Modelling of Electric Powertrain for Heavy-Duty BEV

The automotive industry plays a crucial role in battling the climate crisis and reducing emissions. Medium-duty and heavy-duty vehicles alone contribute to one-fourth of global emissions in the transport sector and there is a positive trend in the demand for these vehicles. Battery Electric Trucks have the potential to transform the growing...

Online-parameter-estimation of a PMSM in an EV-powertrain: including thermal measurements

This paper proposes an online motor-parameter-estimator for a PMSM in an EV-powertrain. The proposed method differs from the conventional approach by using thermal measurements to decouple the resistance estimation from the rest of the estimation. Conventional approaches use the voltage and current measurements to estimate all parameters at once...

A Predictive Energy Management Strategy for Plug-in Hybrid Electric Vehicles utilizing Route Preview

A Plug-in Hybrid Electric Vehicle (PHEV) can achieve a considerably higher overall fuel economy than conventional vehicles. The fuel economy of PHEVs however, strongly depends on the supervisory control strategy of the hybrid powertrain. Compared to conventional, non-predictive, supervisory control systems, predictive control methods can further...

Powertrainontwerp voor een fuel cell raceauto

Formula Zero Delft is een raceteam dat sinds 2007 racevoertuigen met een fuel cell bouwt. In dat jaar nam de stichting deel aan de eerste competitie voor waterstof karts. In de twee jaar hierna heeft het team nog twee karts gebouwd waarna de overstap naar Formula Student auto's is gemaakt. Na twee jaar in de Formula Studentcompetitie gaat het...
