India Unveils First Solar-Powered EV Charging Station with Second-Life Battery Storage at Bengaluru Airport

03 June 2025, In a significant advancement toward sustainable urban mobility, India has launched its first solar-powered electric vehicle (EV) charging station utilizing second-life battery storage. Located at Galamma Circle near Kempegowda International Airport in Bengaluru, the station marks a milestone under the Renewable Energy to Electric Vehicle (RE2EV) pilot initiative, part of the Green Urban Mobility Innovation Living Lab. This project is supported by GIZ India, BESCOM, and the Directorate of Urban Land Transport (DULT), under the SUM-ACA (Sustainable Urban Mobility – Air Quality, Climate Action, Accessibility) framework.

Inaugurated by Karnataka Energy Minister Shri K.J. George, the station combines a 45 kWp rooftop solar photovoltaic system with a 100 kWh Battery Energy Storage System (BESS), repurposed from second-life EV batteries. This combination allows for uninterrupted, 24/7 EV charging even during night hours and peak energy demand improving grid stability and enhancing energy efficiency.

The use of second-life lithium-ion batteries aligns with national priorities in circular economy adoption and electronic waste management. The initiative contributes to reducing the carbon footprint of EV infrastructure, extending the utility of battery resources beyond their automotive lifecycle.

Delta Electronics India, a leading player in EV infrastructure, has supplied nine DC fast chargers for the project five 50 kW units and four 30 kW units. These chargers support a wide spectrum of EVs, including private, commercial, and fleet vehicles. With over 8,000 chargers deployed across India and 3 million globally, Delta reinforces its commitment to advancing clean mobility solutions.

The Bengaluru Urban district currently hosts over 4,460 of Karnataka’s 5,880 EV charging stations. With 140 new stations added in 2025, this latest installation significantly boosts charging infrastructure in a high-traffic transit zone near the airport. The facility is capable of simultaneously charging up to 23 vehicles, including 18 via fast-charging and five through slow-charging ports.

Users can access the station using BESCOM’s “EV Mitra” app, which displays real-time information on charger availability and tariffs. Charging sessions can also be initiated via QR codes and are integrated with WhatsApp for seamless payments. Notably, the station offers rates lower than many private alternatives.

Designed as a scalable model, the RE2EV project integrates renewable energy, circular battery usage, and digital charging management systems. It aims to be replicated across other urban and peri-urban locations, reinforcing India’s EV ecosystem through sustainable infrastructure and energy resilience.

Delta Electronics India, with four manufacturing units and two R&D centers nationwide, continues to play a pivotal role across power electronics, automation, and infrastructure domains, actively contributing to India’s energy transition.
