FLASH CHARGING The rolling stock is fitted with an on-board energy storage facility offering two benefits: catenary-free power supply and energy savings thanks to brake energy regeneration. The tramway charges at a standstill (often at a tramway stop) and can run autonomously as far as the next charging point (the next station).

Energy can be captured: • through overhead line sections (usually located in tram stop) • through the ground.

CONTINUOUS GROUND-LEVEL POWER SUPPLY 3 MAIN TYPES OF SOLUTION EMBEDDED POWER RAIL A ground-level power rail embedded in the tramway platform

MAGNETIC INDUCTION Electrical transmission by induction. Embedded into the infrastructure, a primary circuit creates a magnetic field, whilst a secondary circuit on board transforms this magnetic field into electricity to power the tramway.

GROUND-LEVEL CONTACT LINE Small magnetised sections crowned with a series of steel plates are embedded into the platform, between the rails. The rolling stock charges through these sections using retractable collector shoes.
