E‑mobility is growing rapidly. But the more electric vehicles there are on the road, the more urgent one question becomes: what happens to the batteries after their first use? Different designs, a wide variety of loads and individual ageing processes – every battery tells its own story. Or as we say: we are facing enormous variability. No battery is the same as another.
At the same time, societal expectations for genuine sustainability are increasing. Companies and consumers expect solutions that conserve resources and reduce the CO₂ footprint. And one thing is clear: recycling alone is not enough. Many batteries are far too valuable after their “first life” to be dismantled. And this is exactly where remanufacturing comes into play: batteries are inspected, reconditioned and prepared for a second life. This can be as a spare part, in a vehicle (second use) or as stationary storage (second life). Depending on their origin, entirely individually. Similar to a caterpillar that lives a second life as a butterfly.
Since February 2023, we have been developing a fully digital, automated remanufacturing line together with strong research partners. The structure initiated by Fraunhofer IPT maps the entire process chain – from intelligent condition diagnostics to flexible disassembly and certified reprocessing.
At its core is a networked assembly line that independently makes decisions using AI, sensor data and modern diagnostic methods. The game changer? Automation. It enables economically viable operations despite the high variability of battery modules. Digital twins make the entire process transparent – energetically, economically and ecologically. This clearly shows which form of further use makes the most sense.
In our Battery Hub and our workshops, we test modules under real conditions. We analyze, evaluate and develop test systems that can later be integrated into fully automated production lines. The combination of real testing and digital simulation delivers a level of accuracy that has not existed before. Our intention: as soon as we reliably know how healthy a module is, we can bring it exactly to where it creates the greatest benefit. Targeted. Fast. With real added value.
Today, much is still done manually. But in the REVAMP system, this process will be scalable, flexible and extremely efficient in the future. And it is precisely this scalability that determines whether second‑life circular systems really work.
REVAMP creates more than technology: it creates a model that can sustainably transform the battery industry. Reused components mean less demand for primary raw materials, longer value creation lifetimes, lower CO₂ emissions and greater transparency and predictability through digitalization.
With our expertise in development, testing, digital factory planning and simulation, we create solutions across the entire battery life cycle. The close integration of digital and physical processes accelerates innovation and enables sustainable, data‑based decisions.
For us, one thing is clear: remanufacturing is not just an answer to today’s challenges. It is a key building block for the mobility of tomorrow. We believe in this. The REVAMP research project is like a butterfly. A master of the complete life cycle. And of second life.
