We are looking for the best engineers to create fast chargers that will enable large-scale electric mobiltiy

Work package 5: Charging mobility – Medium-voltage charger technology


  1. Develop a MV-charger proof of concept: ultra-fast bidirectional charging technology that can be
    connected directly to the medium voltage electricity grid without a 10kV/400V transformer and is
    especially suitable for heavy transport where high power is needed.
  2. Determine the impact and possibilities of high power V2G (vehicle to grid) and grid support on
    future grid configurations, resulting in optimal use of renewable energy.
  3. Provide input and check output regarding the business case of MV chargers for busses, trucks and
  4. Develop distributed control algorithms that enable grid stabilization using (multiple) MV chargers,
    supporting the development of future ICT standards (input for WP8).
  5. Provide input to and check output of the integral model to determine the impact (both positive
    and negative) of these high-power chargers.
  6. Analyse the legal ramifications of directly connected high-power chargers to the electricity grid.
  7. Determine optimal future charging combinations, comparing the use of fast charging, opportunity
    charging, overnight charging, destination charging and caternary charging) for different business
    cases (e.g. busses, ships, trucks and maybe even ultra-fast charging of regular cars). This
    objective also requires a thorough analysis of individual preferences.


  1. Charger supported MV grid capacity optimization with societally desirable incentives and business
    models (Enexis, Liander, Elaad, Enpuls, TU Delft, TU/e, HvA)
  2. Modular bidirectional power conversion for MV grid-connected ultrafast chargers (Damen, Heliox,
    IHC, Prodrive, Elaad, TU/e)
  3. Scalable distributed control techniques for networks of grid connected high-power chargers
    (Enpuls, Enexis, Liander, TU/e)
  4. Power converter architectures with extended lifetime and zero downtime (Heliox, Prodrive, TU/e)
  5. Improved reliability, power
