Evyon maximizes the value of second-life EV batteries by repurposing them into high-quality energy storage systems in a streamlined, safe, and cost-effective way. We develop novel technologies for reassembly and operations to convert usable second-life EV batteries into modular plug-and-play battery storage systems. Our ambition is to make battery storage truly accessible for a wide range of applications, including reducing peak energy demand (peak shaving), increasing self-consumption of energy from solar panels, providing critical services to grid operators, and increasing available power in an environmentally friendly way to underserved locations and applications.
