Today’s Second-life Solution cannot Meet Tomorrow’s Demand
Classic Solution
The conventional second-life battery process involves multiple lengthy steps: battery extraction, disassembly, sorting, screening, reassembly, and finally, deployment.
This approach is time-consuming, expensive, and introduces safety risks.
How we give an EV battery a better second-life ?
WPU Solution
In contrast, our method reuses retired EV batteries directly - without any dismantling.
This groundbreaking concept is what we call Whole Pack Utilization (WPU) technology.
We MUST Reimagine how Retired Battery should be Reused
WPU: Whole Pack Utilization
The World’s Leading Second-life Technology
Retired
EV batteries are typically retired and replaced after 8-10 years of vehicle use - especially once their State of Health (SOH) falls below 80%.
Reused
CycleWatt reuses retired EV batteries directly - without any dismantling - to build second-life Battery Energy Storage Systems (BESS). Our technology extends the life of these batteries by an additional 8–10 years.
CycleWatt’s WPU Technology Offers Numerous Significant Advantages
Lower Cost
By eliminating the complex and costly dismantling process of classical solutions, our innovative WPU (Whole Package Utilization) approach reduces the total system cost by up to 40%.
Higher Safety
Our systems inherit all the rigorous safety features of their original automotive-grade EV batteries. As a result, we are able to build a second-life BESS that is safer than a new one.
Less CO2
The extended second life enabled by our technology results in a substantial reduction in lifecycle emissions, decreasing the carbon footprint by up to 45%.
Easier EoL Recycling
Following its second-life application, our WPU technology facilitates straightforward recycling, minimizing processing costs and environmental impact at end-of-life.

CycleWatt on BFM Business
In the programme Paroles d’Entreprises, CycleWatt shares its vision for giving a second life to electric vehicle batteries by transforming them into energy storage solutions.
Our approach is based on the reuse of the complete battery pack, without dismantling. Batteries removed from vehicles often still retain a large part of their capacity and can be used for stationary applications such as fleet charging, industrial sites, renewable energy integration, and peak shaving.
Built on 8 years of R&D, CycleWatt aims to make energy storage more competitive, circular, and local, while contributing to Europe’s energy sovereignty.
CycleWatt turns an end-of-life battery challenge into an energy resource for Europe.
