Battery analytics that extend fleet and storage lifespan.
Photo slot — deterministic SVG cover art (demo).
Voltarna builds analytics that extend the useful life of battery fleets — buses, delivery vans, and grid storage. By modeling degradation from charge patterns and thermal history, it tells operators which packs to rotate, rest, or retire before failures get expensive.
The company started in Helsinki in 2020, close to the Nordic bus fleets that became its first customers. Voltarna's wedge is honesty about uncertainty: predictions ship with confidence bands, and the product is designed around decisions operators make weekly, not lab-grade precision they can't act on.
