To progress beyond the state-of-the-art, the ambition of Workstream 1 is to realize a heat exchanger designed following a smart thermal management approach with the following capabilities:

  • The development of a multi-criteria and multidisciplinary decision method to select the best candidate for the heat sink design
  • To exploit the capabilities and take into account the limits of additive manufacturing by embedding within the optimization tool the geometric constraints but allowing complex shapes, choice of the metamaterial density, etc.
  • To conceive this optimisation tools as open as possible, so that new physics or constraints could be added in future

In the current state-of-the-art there is no combined data from a WPT design point of view (track length, layout, power transfer, or transfer efficiency), and opportunistic charging studies with actual tram routes (workstream 2). RECET4Rail will go beyond and deepen on the actual impact regarding the downsizing of the on-board ESS, which will be evaluated in specific routes with static, semi/quasi dynamic, and dynamic charging systems.

Designers need validated lifetime models that go into their respective tool for reliability and lifetime calculation based on the respective mission profiles obtained in specific train operation (workstream 3). Those lifetime models do not exist for SiC components or the models are too vague. RECET4RAIL will advance in this area, taking into consideration short circuit capability, instability of the gate system, bipolar degradation, cosmic ray effects and humidity capability.

Workstream 4 will achieve advances in the application of Prognostic and Health Management in the rail sector, in order to develop cost-effective Predictive Maintenance (PdM) solutions.
