R&D Roadmap on EV Charging Infrastructure
The “R&D Roadmap on EV Charging Infrastructure,” prepared by the Climate, Energy and Sustainable Development Division, Department of Science and Technology (DST), India, outlines technological pathways to address key challenges in electric vehicle (EV) charging infrastructure development, aligning with national e-mobility goals. It identifies critical areas for R&D and proposes solutions tailored to Indian requirements.
Key Highlights
- LEV Infrastructure Challenges & Recommendations:
- Indigenizing DC chargers (12 kW) to reduce reliance on imports.
- Introducing universal sockets for compatibility across charging standards.
- Employing solar-powered DC microgrids for sustainable charging in rural and urban areas.
- High-Power Charging Systems:
- Exploring Dual-Gun Chargers for faster power delivery, pantograph systems for e-buses, and catenary systems for electric freight trucks.
- Assessing grid readiness for megawatt-scale charging demands and ensuring robust safety standards.
- Interoperability Solutions:
- Standardized connectors and communication protocols to simplify EV charging.
- Creation of a Unified Energy Interface (UEI) akin to UPI for seamless access across different operators.
- Research and Innovation Needs:
- Development of Indian standards for emerging technologies like inductive and dynamic wireless charging.
- Pilot testing of advanced systems like solar-integrated microgrids, pantograph chargers, and split charging systems.
Way Forward:
Supporting industry-academia collaboration to develop cost-effective and scalable charging technologies. Promoting policies that integrate renewable energy, enable battery swapping, and ensure grid stability. The roadmap highlights the necessity of a multi-stakeholder approach, combining policy support, R&D, and private-sector involvement to overcome barriers in EV charging infrastructure and accelerate India’s transition to e-mobility.
