Cheap and profitable: a “megabattery” has been created from old electric vehicle batteries

The G-One energy storage system, assembled from used batteries, costs 40-60% less than conventional ones, and is also equipped with a fire extinguishing function.

The Spanish startup GDV Mobility from Alicante presented the G-One energy storage system, assembled from used electric vehicle batteries, at the Mediterranean European Battery Summit. This writes ESS News.

According to the company, the 7 MW “megabattery” is a “cheap, profitable and safe” product. It costs 40-60% less than a conventional stationary energy storage system, but without compromising performance.

“We offer electric vehicle brands a network of more than 40,000 workshops. If a battery fails, we restore it. We create megabatteries from recycled batteries,” — said GDV CEO Herman Agullo.

The system includes 484 battery modules with a capacity of 14 kW and a modular fire extinguishing system, which works on the principle of flooding individual compartments, which in the event of a module fire ensures its isolation and extinguishing.

The company plans to rent the G-One. The “megabattery” is compatible with inverters with an operating voltage of 600 to 1500 V and is integrated with a battery management system. According to the manufacturer, the device is easy to connect and has a pre-assembled factory package, and the modular design ensures quick installation.
