India has launched its first indigenous wireless Electric Vehicle (EV) charger, a major milestone in the country’s electric mobility industry.
C-DAC Thiruvananthapuram and Visvesvaraya National Institute of Technology (VNIT) Nagpur developed the charger.
The device is aligned with the government’s ‘Make in India’ and ‘Atmanirbhar Bharat’ campaigns. It provides an easy, cable-free charging option for EV users.
The Innovation: Made-in-Bharat Wireless EV Charger
The publicly announced wireless EV charger works with a conventional 230V, 50Hz AC electric supply and contactless transfers of 1.5 kilowatts of power.
It wirelessly charges as much as 90% of a 4.8 kWh battery in around three hours. With SiC-based MOSFETs at an 88 kHz operating frequency, the charger up to a coil separation of 12.5 cm delivers a peak efficiency of 89.4%.
Advanced safety features such as short circuit and open circuit protection will keep you and your device safe. It’s a big step toward autonomy in EV tech.
Technical Specifications and Charging Efficiency
The wireless charger uses high-frequency resonance technology to make charging more efficient. Constructed for the ideal coil separation, not to exceed 12.5 cm, for easy use and installation.
The charger switches at 88 kHz with SiC MOSFETs to improve efficiency and thermal performance.
The charger has a peak charging efficiency of 89.4% and will not waste power in the charging process. This spec makes it a possible solution for home and public stations for EV charging.
Impact on India’s EV Ecosystem
The new wireless EV charger is expected to plug several gaps in India’s electric mobility space. This, along with 4.5 million electric vehicles plying on Indian roads, makes the demand for efficient and easily accessible charging solutions crucial.
This advances us beyond reliance on physical connectors that are managed and used in the same ways that they have been for decades. Encouraging domestic manufacturing and reducing dependence on imported technology, the charger helps accelerate the development of local electric vehicle (EV) charging infrastructure, thus contributing to the vision of self-reliant India.
Government Support and Future Prospects
Wireless EV chargers have been developed with the support of the Ministry of Electronics and Information Technology’s (MeitY) National Mission on Power Electronics Technology (NaMPET). “These kinds of innovations will help to scale up electric vehicle adoption across the country,” MeitY Secretary S. Krishnan had said.
The technology has been licensed to Global Business Solution Pvt. Ltd., announcing that it is about to navigate in the market. Further developments might consist of higher power and dynamic charging.
Also, the government also aims to add this Indigenous technology into the public infrastructure in and around the smart cities, which would allow wider accessibility and encourage both private and commercial EV adoption through the use of these policies, subsidies, and through strategic industry-academic collaborations.
An innovative step toward simple and sustainable electric mobility options is India’s domestic wireless EV charging. It makes charging easier and more effective by doing away with the requirement for physical connectors.
Innovations such as these will be essential in helping India’s drive for a more sustainable and independent future as the nation’s electric vehicle ecosystem grows. In terms of EV infrastructure, this wireless charging technology is only the start of a new age.
