Key aspects to enable multi-megawatt fast charging

At present, the mobility sector in Europe is in the middle of a transition phase. Combustion engine-based vehicles (CV) are meant to be replaced by electric vehicles of the same type in order to fulfill the zero emissions targets within the next decades. This requires a collaborative approach from the industry, research institutes, and national governments in order to prepare both the necessary vehicle technology and infrastructure accordingly. Even though various attractive charging solutions in the hundreds of kilowatt range already exist commercially, heavy-duty vehicle charging in the multi-megawatt range is still a topic to be investigated in more detail in the scientific community. Therefore, this publication discusses different strategies to enable fast charging in the megawatt range and presents a concept that is directly connected to the medium voltage grid while enabling distributed charging and an optimized carbon footprint due to the adoption of renewable energy systems.
