The innovative solutions have been developed by eWaste, a subsidiary of Solarpro - a multi-technology integrator in the renewable energy industry
SOFIA, BULGARIA, May 14, 2025 /EINPresswire.com/ -- Bulgaria already has the first energy storage systems using second life batteries. These are systems built from end-of-life lithium-ion batteries from electric vehicles - batteries that no longer meet standards for use in vehicles but can still be used in a variety of secondary applications before being recycled.
The first such systems were developed by eWaste, a subsidiary of Solarpro and a member of the European Battery Recycling Association (EBRA Recycling). The two pilot systems use battery modules from Volkswagen Group electric vehicles, with each system having a capacity of 4.2 kWh and equipped with a fully hybrid inverter. This means that the inverter intelligently manages the energy flow - it can charge the batteries from solar panels as well as from the grid or a generator, automatically allocating energy to consumption according to the needs of the household or site. The company plans to roll out about 20 such systems a month.
To date, eWaste has signed contracts with 18 importers of electric vehicles in the country, including Silver Star Motors EAD, Euratek Auto Ltd, Mirkat Ltd, Porsche BG Ltd, Vitosha Sports Cars Ltd, Vitosha Auto Ltd, Balkan Star Motors JSC and others. The brands that eWaste works with include Mercedes, Skoda, Suzuki, VW, Audi, Porsche, Infinity, Jeep, Alfa Romeo, Hyundai, Mitsubishi and NISSAN.
In addition to the innovations in the energy sector, as part of its corporate social responsibility, the company will donate the pilot two systems to PGKMCS "Acad. Blagovest Sendov", Varna (Vocational School of Computer Modelling and Computer Systems) and the Technical University - Varna, where they will be used for educational purposes as well as for real application.
