About

Battwoo is an industrial deep‑tech company focused on the reuse of electric vehicle batteries for stationary energy storage applications.

We design, integrate and operate second‑life Battery Energy Storage Systems (BESS), transforming end‑of‑first‑life EV batteries into safe, reliable and cost‑effective assets for industrial, commercial and energy infrastructure use.

Battwoo acts as an industrial enabler of battery circularity, managing the technical, safety and operational risks associated with second‑life batteries. Our activities cover battery selection and characterization, system design and integration, safety engineering, monitoring, and real‑world pilot deployment.

We collaborate with industrial partners, research and technology organisations and energy stakeholders to demonstrate, validate and scale circular energy storage solutions at TRL 6–8, generating real operational data and measurable environmental impact.

Within RIV Circular, Battwoo is interested in participating in collaborative projects focused on EV battery reuse, pilot demonstrations, system validation, safety, performance assessment and lifecycle impact, contributing to the development of replicable circular energy solutions in Europe.
