Value proposition
Turning Retired EV Batteries into Energy Storage Assets
CycleWatt develops next-generation Battery Energy Storage Systems (BESS) by giving retired electric vehicle batteries a second life.
Our patented Whole Pack Utilization (WPU) technology enables the direct reuse of EV battery packs without dismantling, reconfiguration, or cell sorting. This approach significantly reduces processing complexity while preserving the original battery architecture.
Key figures:
• 8 patented innovations protecting our technology portfolio
• Up to 40% reduction in BESS system cost
• Up to 45% reduction in battery lifecycle carbon footprint
• Up to 8-10 additional years of battery service life
• Modular systems ranging from 100 kWh to multi-MWh installations
Built on expertise developed through European automotive and energy storage programs, our team combines experience in EV battery systems, Battery Management Systems (BMS), energy management software, and large-scale energy storage deployment.
CycleWatt provides complete second-life battery solutions for battery owners, automotive OEMs, battery manufacturers, recyclers, energy developers, and industrial customers.
Applications include:
• Commercial & Industrial Energy Storage(C&I)
• Renewable Energy Integration
• EV Charging Infrastructure
• Backup Power Systems
• Microgrids and Off-Grid Energy Systems
• Mobile Energy Solutions
Our mission is simple:
Extend battery life, reduce waste, lower energy storage costs, and accelerate the transition toward a circular and low-carbon energy economy.
