Alligator

About

Founded in 2021, Alligator is a private headquartered in Rotkreuz, Switzerland with approximately 10-50 employees specializing in Energy Storage.

Alligator AG is a Swiss startup founded in 2021 that addresses the decarbonization of heavy-duty vehicles by integrating trailers into the high-voltage energy networks of electric semi-trucks. The company has developed planar feedthrough technology—a patented solution that enables safe, practical connection of high-voltage power lines between tractor and trailer while driving, without requiring manual cable connections. This technology is fully encapsulated, sealed, and shielded, integrating into trailer floors without loss of cargo volume and remaining compatible with existing fifth-wheel couplings. The company's flagship product is the B-Trailer (Powerbank Trailer), a semi-trailer equipped with batteries connected to the tractor's energy network, enabling flexible energy sourcing, storage, and transfer. Alligator has completed prototype development, conducted successful test drives on Swiss roads, and is pursuing a pilot project with logistics partners. The company has secured support from Innosuisse, the Swiss Climate Foundation, and the Albert Köchlin Foundation, and has been recognized as a finalist in multiple startup competitions including the Helbling Venture Challenge 2025 and the W.A. de Vigier Award Top 15.
