In Germany, an industrial energy storage device is collected from old electric scooter batteries. The idea belongs to the start-up EDEN Energy, which created a driving capacity of 70 kilowatts. The project is interesting because many of these batteries are thrown away before time, even though they hold more than 90% of their original capacity and can last for several years. The main feature of the development in its power electronics. This allows you to combine batteries of different types and designs into one system without discouraging them. In fact, it solves one of the main problems of reusing batteries, because they can differ in the type of elements, design and control systems. The first unit was collected from 112 tested batteries. The developers were supposed to retain 80% of capacity, but tests have shown that some batteries hold more than 90%. In mid-October, EDEN Energy delivered the first drive to a customer, a plant with a solar power plant. ️ However, the heterogeneity of batteries is also the main "god" of the technology. Scooter batteries often differ in cell types, design, connectors and control systems, so each new type needs to match connections, control system and communication. Because of this, reducing the technology is quite difficult. So far, EDEN Energy focuses on medium-sized enterprises that need to accumulate excess solar energy. The company plans to increase the capacity of its industrial systems to 300 kilowatts. Cycle on Telegram | In MAX.
