FLEXMCS

Acronym:  FLEXMCS
Title: Flexible Megawatt Charging Systems, open software architectures, and planning modules creating multi-charger hubs for the European electric mobility system

What are the main challenges regarding charging infrastructure for the mass deployment of electric trucks?
The transition to electric heavy-duty vehicles (HDVs) faces several major hurdles. Charging infrastructure is currently insufficient, both in terms of availability and power capacity. The grid must be able to support high-power fast charging, but capacity limitations and energy distribution inefficiencies present significant challenges. Additionally, charging stations need to be flexible and scalable, accommodating different types of vehicles while ensuring cost-effective deployment

Can you provide a brief overview of how the FLEXMCS project will address these challenges?
In the EU FLEXMCS project, we are developing multiport Megawatt charging systems with 4 MCS and up to 18 CCS outlets, optimizing usage by enabling fast charging for HDVs and overnight charging for light vehicles. To reduce grid impact and energy losses, we will integrate renewable energy sources and stationary energy storage systems (BESS). Additionally, an Open Charging Framework will enable real-time data exchange between charge point operators (CPOs) and trucks, ensuring smart energy management. The project will be validated through a real-world demonstration in Karlsruhe, Germany, assessing scalability, technology effectiveness, and business viability.

What role does VUB play in the FLEXMCS consortium, and what will be some of its key contributions?
VUB, through the EPOWERS Research Group at VUB-ETEC-MOBI, is coordinating the EU FLEXMCS project. VUB will also develop tools to optimize both the chargers' power electronics architecture and charging site layout. These tools will enable enhanced combined charging for both CCS and MCs outlets and provide an optimal site design for different business cases. Further, VUB will define the multi-layer EMS architecture and specifically contribute to a medium-level controller, for the optimal modular operation of the chargers. VUB will also provide a lifetime assessment tool for power electronics health degradation. Finally, VUB will support in the TCO assessment linked to large-scale geographical deployment strategies of the solutions.

What will be the broader impact of FLEXMCS?
EU FLEXMCS will accelerate the deployment of megawatt charging infrastructure, making zero-emission freight transport more viable and cost-effective. By optimizing charging efficiency, expanding grid capacity, and integrating renewable energy, the project will help logistics operators reduce costs, lower emissions, and increase fleet reliability.
