Swiss startup Winduction develops wireless charging system that transfers power through bus tyres
By Eve
Winduction, an ETH Zurich spin-off, has created an inductive charging system that transfers electricity through vehicle wheels rather than the undercarriage, addressing efficiency losses caused by varying ground-to-vehicle distances in conventional wireless systems. The technology aims to reduce operating costs for electric bus fleets by enabling regular charging during operation, allowing smaller battery packs and fewer charging stations. The system uses induction coils housed in ground plates set into the road surface.
Why it matters
This tyre-based charging approach could reshape procurement specifications for bus depot and route infrastructure, as it promises higher efficiency than undercarriage systems and potentially lower capital costs through reduced battery and charger requirements. Operators and infrastructure planners evaluating wireless charging tenders may need to compare this ground-contact method against established pad-based solutions from suppliers like Momentum Dynamics.

Seattle opens applications for 200 curbside Level 2 chargers targeting apartment areas by 2030
Seattle City Light is accepting resident applications for up to 200 new curbside Level 2 EV chargers to be installed from fall 2027 through 2030, prioritising multifamily housing areas with limited existing charging. The city will review applications and select locations in batches of 40 to 50 sites, with design and permitting starting spring 2027 and each site requiring approximately two weeks of construction. Seattle already operates 58 chargers from an earlier pilot programme.
Why it matters
The resident led application process and phased procurement model offers a replicable framework for cities targeting underserved multifamily housing, with clear timelines for design, permitting and installation that CPOs and contractors can plan around. The batch selection approach creates predictable tender windows for equipment suppliers and installation firms through to 2030.
