e-TOWER: The Sustainable and Efficient Solution for Ultra-Fast Electric Vehicle Charging
GDES Circularity and Zeleros have combined their expertise and technology to develop e-TOWER, an innovative solution that redefines sustainable mobility by addressing one of the main challenges in the sector: the efficient management of resources and waste.
e-TOWER drives the transition toward a more circular, sustainable, and competitive energy model, reaffirming both companies’ commitment to responsible innovation while providing an effective response to the growing demand for ultra-fast electric charging infrastructure.
A Sustainable and Efficient Response
e-TOWER makes use of second-life batteries from the automotive industry — batteries discarded during production, verification, and testing processes, yet still holding the same industrial safety and operational guarantees.
In doing so, it transforms potential waste into a key resource for the circular energy transition, preventing up to 50 tons of CO₂eq emissions per installed unit.
The system integrates modular energy storage with an initial scalable configuration of 500 kWh, which allows:
-
Ultra-fast and simultaneous charging of up to 4 electric vehicles at once.
-
Reaching 80% charge in approximately 11 minutes.
-
Installing high-power chargers in locations where the power grid would not otherwise permit it — without requiring medium-voltage connections.
Moreover, e-TOWER is designed to integrate directly with 100% renewable energy sources, reinforcing its sustainable character compared to other solutions on the market.
This technology is the result of collaboration between GDES Circularity — the GDES division specialized in Circular Economy and Supply Chain — and Zeleros, a benchmark in electrification and advanced mobility technologies.
e-TOWER targets clients such as Charge Point Operators (CPOs), operators of unique service station sites, and companies seeking to provide fast charging in a sustainable and efficient way.
Furthermore, the product’s circular approach offers a solution for automotive Original Equipment Manufacturers (OEMs) looking to repurpose batteries that can no longer be used in electric vehicles but remain safe and functional for industrial applications.
e-TOWER closes the loop of electric mobility by turning a challenge into an opportunity—transforming electric vehicle batteries themselves into the key to deploying more and better fast-charging points.
It is a solution that promotes sustainability, maximizes efficiency, and accelerates the future of mobility.
