India Launches First Solar-Powered EV Charging Station with Second-Life Batteries

India has launched its first solar-powered electric vehicle (EV) charging station integrated with second-life battery storage at Galamma Circle near Kempegowda International Airport, Bengaluru. The initiative is part of a pilot project under the Green Urban Mobility Innovation Living Lab, supported by GIZ India, BESCOM, and the Directorate of Urban Land Transport (DULT), under the Sustainable Urban Mobility – Air Quality, Climate Action, Accessibility (SUM-ACA) program.

The Renewable Energy to Electric Vehicle (RE2EV) project was inaugurated by Karnataka Energy Minister Shri K.J. George. The station combines solar power generation with battery energy storage, using repurposed EV batteries. A 45 kWp rooftop solar photovoltaic system feeds into a 100 kWh Battery Energy Storage System (BESS), allowing for 24/7 charging availability. The stored solar energy can be used during night hours and peak demand periods.

This approach supports energy efficiency, eases pressure on the power grid, and extends the operational life of lithium-ion batteries. It also aligns with national goals on circular economy and electronic waste management.

The charging hub includes nine DC fast chargers—five 50 kW and four 30 kW—supplied by Delta Electronics India. Delta has supplied over 8,000 chargers in India and over 3 million globally. The chargers are compatible with a range of vehicles, including private, commercial, and fleet EVs.

Karnataka has over 5,880 EV charging stations, with 4,462 located in the Bengaluru Urban district. The state has added 140 new chargers in 2025. The new hub can charge up to 23 vehicles simultaneously and is positioned to serve a high-demand transit area near the airport.

Users can access the station through BESCOM’s “EV Mitra” app, which provides real-time data on charger availability and pricing. Charging can also be initiated through a QR code with payment integration via WhatsApp. The station offers 18 fast-charging points and five slow-charging points. Tariffs are set lower than those at private stations.

The RE2EV project is designed as a replicable model for other urban and peri-urban locations. It integrates renewable energy, second-life battery usage, and high-capacity charging infrastructure to improve sustainability and grid resilience.

The initiative is a step in building a broader EV ecosystem in India, supporting not only vehicle adoption but also localized energy solutions, storage, and digital management systems.

Delta Electronics India Private Limited operates in Power Electronics, Automation, and Infrastructure sectors. The company provides telecom power, renewable energy, display systems, automation, UPS and data center solutions, EV charging systems, and energy storage. It operates four manufacturing facilities and two R&D centers in India and maintains a network of over 200 channel partners.
