1st Workshop on Advanced Charging Systems – WACS 2022

The fast rise of the oil prices in the first months of 2022 is painful but can be a chance to speed up the
change to electric vehicles as they become more competitive in terms of cost. With government support,
the number of cars in countries like Poland is rising; however, still, the bottleneck is the lack of suitable
charging infrastructure. There is no doubt that widely available and fast charging infrastructure is a key
to the success of the e-mobility revolution.
Experiences from the field show in many cases that installation of the classical electrical vehicle chargers
maybe not be enough. When the peak power of the charging system is higher than the available power
of the connection point, we may need energy storage. The best solution is to take advantage of the used
batteries, which do not fulfil automotive standards but can still be applied in less demanding
applications. Another challenge is the rising voltage of the batteries to be charged; the internal DC links
of the charging stations may also reach the medium voltage level or become bipolar. Moreover, the
latest technologies, to mention Silicon Carbide power devices, are fast spreading in the EV chargers.
Finally, to reduce the system cost and improve reliability, the modular approach is required.
Some of these issues are addressed in the project “Modularized, Reconfigurable and Bidirectional
Charging Infrastructure for Electric Vehicles with Silicon Carbide Power Electronics (MoReSiC)”,
conducted by teams from Warsaw University of Technology, Norwegian University of Science and
Technology (NTNU) in Trondheim and Markel sp. z o.o. The first outcomes of the project will be
presented and discussed during the workshop, but the presentations on the advanced charging systems
from other research groups will also take place.
