Swedish Electric Transport Laboratory, SEEL, Säve

The Swedish Electric Transport Laboratory (SEEL), owned by RISE and Chalmers, is one of Europe’s most advanced test and demonstration environments for electrified transport systems. The facility in Säve, Gothenburg, covers 14,000 m² and offers complete testing capabilities from battery cells to fully assembled vehicles.

As part of the pan-European IPCEI initiative, SEEL provides cutting-edge research and independent testing capabilities within energy storage, driveline technology and recycling – support that makes the development process faster, safer and more cost‑efficient.

Test, verify and optimise your electrification with us

In Säve, we offer advanced testing of battery cells, modules and packs in climate and thermal chambers. The facility also includes test cells for electric machines, e‑axles and complete drivelines, including NVH analysis. We test both light and heavy electric vehicles, charging functionality, hydrogen systems and infrastructure interaction. The environment supports everything from concept development to validation and certification.

We offer:

• Climate chambers and advanced cyclers for battery research
• Module and pack testing in thermally controlled environments
• Complete vehicle testing for electric, hydrogen and hybrid vehicles
• Driveline testing for e‑axles and electric machines
• Charging and charging‑infrastructure testing
• An innovation platform for interdisciplinary development

A test environment for industry, research and the public sector

SEEL Nykvarn welcomes actors from the automotive, aviation, maritime and energy sectors, as well as defence and technology‑driven startups. Here, global OEMs and smaller developers access qualified, independent testing capacity. With advanced equipment and deep system expertise, we enable faster, safer and more cost‑efficient development.

SEEL’s facilities – cutting-edge expertise in three locations

SEEL consists of three complementary test facilities. In addition to the site in Säve, there is a facility in Nykvarn equipped with SEEL’s most powerful systems for testing electric axles for, among other things, trucks, buses, and construction machinery. In Borås, there is capacity for safety‑critical battery testing that ensures batteries meet the required safety levels during use, handling, and production. Together, the facilities form a unique national resource for the safe and efficient development of future electrified transport systems.
