Nissan has launched a new ultra-fast EV charging station powered entirely by repurposed Leaf batteries at Spain’s Port of Vigo. The Green Energy Flex hub uses 12 retired 30kWh battery packs to create a 300kWh energy storage system.
Spanish energy specialist Little Green Energy developed the system. It delivers charging speeds up to 240kW through four ultra-fast chargers, plus standard 22kW AC charging options.
The European Union and Spain’s national energy agency co-funded the pilot project.
Charge point operator Galp Electric will run the facility for at least one year. The project shows how automakers can extend battery life beyond their original vehicles – addressing one of the biggest concerns about EV waste.
Second Life for EV Batteries
The Port of Vigo installation demonstrates how retired EV batteries can power charging infrastructure in locations where the electrical grid can’t handle high-demand charging.
Soufiane El Khomri, Nissan’s energy director for Africa, Middle East, India, Europe and Oceania, said the project connects innovation with sustainability.
“Together with Little Electric Energy, we are connecting innovation and circularity to give Nissan Leaf batteries a second life beyond the road.”
El Khomri explained that repurposed battery systems can unlock ultra-fast charging at ports and industrial sites where grid capacity is limited. This reduces pressure on local electrical infrastructure while extending battery value.
“This is how we are supporting the continued growth of electric mobility while building a more resilient, low-carbon energy future,” he added.
The modular design means the system can be scaled up or relocated as needed. Energy storage systems like this one can also help balance renewable energy sources like solar and wind power.
Commercial Viability
Ruben Blanco, CEO of Little Electric Energy, emphasized the commercial potential of repurposed battery technology.
“Nissan has been a pioneer in electric mobility with the Leaf, and together we are now extending that leadership into circular energy solutions.”
Blanco said Green Energy Flex proves repurposed Leaf batteries can deliver fast, sustainable charging that’s commercially attractive. The technology could be deployed anywhere high-speed charging is needed but grid infrastructure is constrained.
This isn’t Nissan’s first major battery reuse project. In 2025, the company used 84 repurposed EV batteries to help power Rome’s Fiumicino Airport – showing how the technology scales to major transportation hubs.
The Port of Vigo project represents a growing trend in the EV industry. As first-generation electric cars reach end-of-life, their batteries often retain 70-80% of their original capacity – still useful for stationary energy storage applications.
