A groundbreaking development in the realm of electric vehicle (EV) technology is set to revolutionize charging efficiency in India. The Ministry of Electronics and Information Technology has announced the transfer of a cutting-edge 1.5 kW wireless charger technology, developed by C-DAC Thiruvananthapuram and VNIT Nagpur, to an Indian firm for commercialization. This indigenous innovation highlights India’s strides in advancing the e-mobility ecosystem under the National Mission on Power Electronics Technology.
The wireless charger operates seamlessly on a 230V, 50Hz AC single-phase supply and is designed to charge a 4.8kWh onboard battery pack at 48V, delivering 30A current in approximately three hours. Achieving a remarkable efficiency of 89.4 percent within a coil separation of 7.5 to 12.5 cm, the system incorporates state-of-the-art Silicon Carbide-based MOSFETs operating at 88kHz, along with robust safety features such as short-circuit and open-circuit protection.
This technology transfer signifies a pivotal moment in India’s pursuit of self-reliance in power electronics and sustainable transportation solutions. By enabling faster, more efficient charging, the innovation is poised to address key challenges in the EV market, furthering the objectives of the ‘Make in India’ and ‘Aatmanirbhar Bharat’ initiatives.
The announcement was part of a broader event showcasing multiple advancements under NaMPET, including collaborations to develop an indigenous propulsion system for electric locomotives and energy-efficient power systems for administrative buildings in Kerala. These initiatives underline the synergy between research, academia, and industry, paving the way for a more sustainable and technologically advanced future.
Another significant development is an indigenous propulsion system for three-phase electric locomotives. This initiative, undertaken in collaboration with C-DAC, Chittaranjan Locomotive Works, and various industry partners, aims to boost the electrification of Indian Railways. The propulsion system integrates high-power traction converters, auxiliary converters, and an advanced Train Control and Management System to enhance performance and operational flexibility. With Indian Railways targeting full electrification by 2030, this project represents a critical step toward achieving self-reliance in railway technologies.
Additionally, the Kerala Development and Innovation Strategic Council, in partnership with C-DAC, has deployed a low-voltage direct current power system at its headquarters, making it the first administrative building in the state to utilize 48V DC technology. This system promises 20 to 30 percent energy savings and aligns with Kerala’s Carbon Neutrality Roadmap for 2050 and India’s broader Net Zero Vision for 2070.
