Discover India’s breakthrough wireless EV charger that powers up to 90% in just 3 hours using a standard 230V supply. Learn how this Made-in-Bharat innovation is revolutionizing electric vehicle charging.
India’s electric vehicle (EV) landscape is witnessing a revolutionary breakthrough with the unveiling of the country’s first indigenously developed wireless EV charger. This innovation is not just a technological marvel but a significant stride toward making electric mobility more accessible, convenient, and aligned with India’s vision of self-reliance under the Make in India and Atmanirbhar Bharat initiatives.
The newly developed wireless charger can replenish up to 90% of a 4.8 kWh EV battery in just three hours, using a standard 230V, 50Hz AC single-phase power supply. This means EV owners can enjoy faster, cable-free charging at home or other locations, eliminating many of the hassles associated with traditional wired chargers.

The Technology Behind India’s Wireless EV Charger
This pioneering wireless EV charger is the result of a collaborative effort between two premier Indian institutions: the Centre for Development of Advanced Computing (C-DAC), Thiruvananthapuram, and the Visvesvaraya National Institute of Technology (VNIT), Nagpur.
The project was developed under the Ministry of Electronics and Information Technology’s (MeitY) flagship National Mission on Power Electronics Technology (NaMPET), which aims to boost domestic innovation in power electronics.
The charger delivers 1.5 kW of power through contactless transmission technology, which means the energy is transferred wirelessly from the charger to the vehicle’s battery without any physical connection. This is achieved using Silicon Carbide (SiC)-based MOSFETs operating at a high frequency of 88 kHz, enabling efficient power transfer even with a coil separation of up to 12.5 cm.
| Feature | Details |
|---|---|
| Power Output | 1.5 kW |
| Battery Capacity Supported | 4.8 kWh |
| Charging Time | ~3 hours for 90% charge |
| Power Supply | 230V, 50Hz AC single-phase |
| Transmission Type | Wireless (contactless) |
| Maximum Efficiency | 89.4% |
| Coil Separation Distance | Up to 12.5 cm |
| Key Components | Silicon Carbide MOSFETs at 88 kHz |
| Safety Features | Short-circuit & open-circuit protection |
The charger’s maximum efficiency of 89.4% is remarkable, especially considering the wireless nature of power transfer and the physical gap between the charger and the vehicle’s receiving coil. Additionally, the device incorporates advanced safety mechanisms such as short-circuit and open-circuit protection, ensuring reliable and secure operation for users.
Why This Innovation Is a Game-Changer for India
India’s EV market is growing rapidly, with over 4.5 million electric vehicles already on the roads. However, one of the biggest challenges hindering widespread EV adoption has been the lack of convenient and efficient charging infrastructure. Traditional wired chargers require physical connections, which can be cumbersome and limit where and how EVs can be charged.
The introduction of a wireless EV charger developed entirely in India addresses these challenges head-on. By enabling cable-free charging, it offers unmatched convenience, especially for home users who can simply park their vehicle over the charging pad without worrying about plugging in cables. This ease of use is expected to encourage more consumers to switch to electric vehicles.
Moreover, the charger’s compatibility with a standard 230V, 50Hz AC power supply means it can be easily integrated into existing electrical infrastructure without the need for costly upgrades. This lowers the barrier for adoption and supports the government’s goal of scaling EV infrastructure nationwide.
MeitY Secretary S. Krishnan hailed the development as a major milestone in India’s journey toward EV self-reliance. He emphasized that innovations like this wireless charger will be instrumental in accelerating EV adoption across the country, perfectly complementing the Make in India and Atmanirbhar Bharat missions.
Commercialization and Market Impact
The technology has been licensed to Global Business Solution Pvt. Ltd. for commercial production, signaling the start of its journey from the lab to the market. This move is expected to catalyze the availability of wireless EV chargers across India, making it easier for consumers and businesses to adopt this new technology.
Industry experts have welcomed the development enthusiastically. Uday Narang, Founder of Omega Seiki Pvt. Ltd., described the wireless EV charger as a “transformative milestone” in India’s clean mobility journey. He highlighted that such innovations not only enhance user convenience by enabling cable-free charging but also reinforce India’s ambition to become self-reliant in EV technology.
This wireless charger is part of a broader push by MeitY to foster domestic research and development in power electronics. Other projects under this initiative include indigenous propulsion systems for electric locomotives and energy-efficient low-voltage DC power distribution systems, all aimed at strengthening India’s technological capabilities in the clean energy sector.
The Road Ahead: What This Means for EV Users
For EV owners, this wireless charger promises a seamless and hassle-free charging experience. Imagine parking your electric vehicle in your garage or parking lot and having it charge automatically without plugging in any cables. This convenience, combined with a fast charging time of just three hours for 90% battery capacity, could significantly improve the daily usability of electric vehicles.
Additionally, the wireless charger’s safety features provide peace of mind, ensuring that the charging process is secure and reliable. This is particularly important as EV adoption grows and more users rely on home charging solutions.
As the charger becomes commercially available, it is expected to complement existing wired charging infrastructure, offering users more options and flexibility. This will be crucial in supporting India’s ambitious target of having 123 million electric vehicles on the road by 2032, as projected by industry analysts.
Conclusion
India’s indigenous wireless EV charger is a landmark achievement that promises to reshape the electric vehicle ecosystem in the country. By combining fast charging speeds, wireless convenience, and robust safety features, this Made-in-Bharat innovation is set to accelerate EV adoption and support India’s clean energy goals.
As the technology moves toward commercial production, it will empower millions of EV users with a more seamless and user-friendly charging experience, helping India drive forward on its path to a sustainable, self-reliant future in electric mobility.
