Job description

At the faculty of Electrical Engineering at Eindhoven University of Technology, a PhD-position is available within the E2GO project, a Marie Sklodowska-Curie Actions (MSCA) Doctoral Network-Industrial Doctorates funded by the EU. The position is open for appointment from September 1st or soonest hereafter and includes a 6 month stay at Delta (PL), a 12 month stay at Shell (NL) and 30 months at TU/e.

We are looking for you!
You will work on the hardware design and optimization of RDC in battery buffered fast-charging stations. You will investigate, optimize and implement a new coupling configuration for battery buffering that is based on a novel reduced dissipation converter (RDC) to enable cost-reduction of Electric Vehicle fast-charging under different scenarios.

Research Programme Description
“E2GO– Cost-reduction of EV fast-charging station to enable large-scale electrification of mobility” is hiring 9 Doctorate Candidates (DCs)” to be funded by the Marie Skłodowska-Curie Actions (MSCA) Doctoral Networks-Industrial Doctorates (DN-ID), 2021, within the European Union's EU Framework Programme for Research and Innovation Europe Horizon under Grant Agreement No.101072414.

The E2GO consortium contains Eindhoven University of Technology, Delta Electronics (Poland) Ltd., Heliox BV, University of Minho, Efacec Electric Mobility SA, Aalborg University, Silicon Austria Labs GMBH, Infineon Technologies Austria AG, Shell Global Solutions International BV, Kema Lab BV and the University of Innsbruck, which brings together the stakeholders that cover the complete value chain of high-power fast-charging stations for EV creating an in-depth training programme that covers the spectrum from hardware design and electronics, to modelling and control algorithms. The multidisciplinary and intersectoral collaboration provides the unique opportunity to achieve the ambitious goal of E2GO to develop innovations to reduce the cost of fast-charging stations for electric vehicles (EVs) for massive deployment. Hence the DCs involved in this project will not only be highly sought-after individuals due to their gained experience at the interface of industrial and academic collaboration, but additionally they will be highly attractive for the automotive industry as experts in the strongly growing field of fast-charging, a frontier research area that will help to address the infrastructural needs and sustainability goals of the 21st century. This constellation will significantly further their individual career paths in industry and academia.

In total 9 DCs will be employed by the project, 7 of those have already started their journey. Being part of a group of DCs will multiply the immediate impact of the training and experience by sharing not only the newly acquired technical expertise but also the “soft knowledge” concerning the different ways of thinking between industry and academia. By this, these DCs will gain a high level of employability and become real translational researchers capable of integrating both worlds of academia and industry.

PhD on hardware design of RDC for Electric Vehicle Fast Chargers (E2GO DC1) (2024)

FAQs

What is the architecture of DC fast charger? ›

Charger architectures. The architecture of the fast charger has evolved into two elements – an active front-end AC-DC converter that can use different topologies, including power factor correction (PFC), and a number of smaller DC-DC power blocks.

What is DC fast charging for electric vehicles? ›

Inside an EV is an on-board charger that converts AC power into DC power before distributing the power to charge the vehicle's battery. DC fast charging bypasses this on-board charger and charges the battery directly, dramatically reducing the time it takes to charge an EV.

How much does DC fast charging infrastructure cost? ›

While existing studies show costs ranging from $20,000 - $150,000, we find costs range anywhere between $122,000 and $440,000. This data is critical for new investment in the U.S. to construct a national charging network of DC Fast charging corridors.

Why is DC EV charging faster? ›

The key difference is that DC is faster than AC charging. When using direct current, energy can be stored in the battery without being converted, which makes the process more efficient and saves time.

How to design a DC fast charger? ›

Design Considerations for DC Fast EV Chargers

When designing off-board chargers, engineers should consider the following: Charging speed - must be appropriate to the EV's battery size and capacity. Safety - built-in safety measures such as overcharge protection, short-circuit protection, and thermal management.

How to design an EV charger? ›

Electric Car Charger Design Considerations. Design considerations for EV charging stations encompass various aspects, including safety, efficiency, scalability, and user experience. Addressing these factors is crucial to ensure that charging infrastructure meets the demands of a growing electric vehicle market.

Who has the largest EV charging infrastructure? ›

With 50,000+ Superchargers, Tesla owns and operates the largest global, fast charging network in the world. Located on major routes near convenient amenities, charger availability and your vehicle charge can be tracked via its app.

What are the cons of DC fast charging? ›

The Impact of Fast Charging on EV Battery Life

One of the biggest concerns with fast charging is that it can damage the electric vehicle's battery, resulting in a significant loss of vehicle range.

Why are DC chargers so expensive? ›

DC chargers cost a lot more than AC chargers. DC chargers require more space and require much more complex spare parts to facilitate processes such as active cooling. In addition, high power charging requires a high power connection to the grid.

What are the disadvantages of EV fast charging? ›

Battery degradation - Some fast chargers for electric cars generate higher temperatures within the battery. Repeated fast charging sessions can also contribute to accelerated battery degradation over time. This may lead to a reduction in overall battery life.

Can a DC fast charger be installed at home? ›

So, can you install a DC fast charger at home? Unfortunately, the answer is no. Since homes and other residential buildings operate on the grid, only AC power is available. Installing a DC charger in a home would require immense structural changes and lots of money.

What are the standards for DC fast charging? ›

Level 1DC Fast Charging
Typical Power Output1 kW50 - 350 kW
Estimated PHEV Charge Time from Empty 45 - 6 hoursN/A
Estimated BEV Charge Time from Empty 540 - 50 hours20 minutes - 1 hour 6
Estimated Electric Range per Hour of Charging2 - 5 miles180 - 240 miles

What is the difference between DC fast and Level 2 chargers? ›

Level 2 AC charging uses a 208/240 volt AC electric circuit. Direct-current fast charger (DCFC), sometimes referred to as a Level 3 DC charging, uses a 3-phase 480 volt AC electric circuit but delivers direct current (DC) to the vehicle.

What power is required for DC fast charger? ›

To support the fast-charging capabilities of a fast charger, a significant level of electricity is needed. Each DC charger requires different levels of energy input. For the 60kW model, 100 amps per phase. The 120kW requires 230 amps per phase and the 150kW requires 250 amps per phase.

Can you put a DC fast charger at home? ›

So, can you install a DC fast charger at home? Unfortunately, the answer is no. Since homes and other residential buildings operate on the grid, only AC power is available. Installing a DC charger in a home would require immense structural changes and lots of money.
