TDB Funds Electrowaves for Indigenous EV Chargers

The Technology Development Board (TDB), Department of Science & Technology, Government of India, has approved financial support to Electrowaves Electronics for the commercialisation of indigenously designed and manufactured EV chargers. The move is aimed at reducing reliance on imported charging systems and expanding domestic EV charging infrastructure.

Electrowaves Electronics has developed AC and DC fast chargers along with power modules, an insulation monitoring device, and communication controllers. The company’s DC fast chargers operate in the 30–240 kW range. Its technology stack includes:

• 15 kW and 30 kW power converter modules (100–1000 VDC output, 100A max current)

• PLC communication controller compliant with DIN SPEC 70121 and partly with ISO 15118

• OCPP communication controller compliant with OCPP 1.6J and OCPP 2.0.1

• Universal DC charge controller with HMI design

The company has also developed AC Type-2 chargers for domestic and public charging applications.

TDB’s support is expected to facilitate scaling of manufacturing and broaden the availability of EV charging systems made in India. It is also likely to strengthen supply chains in the energy and clean-tech sectors.

TDB Secretary Rajesh Kumar Pathak said the organisation recognises the company’s efforts in developing indigenous EV charging technology. According to him, such initiatives contribute to technological self-reliance and support the country’s shift towards cleaner mobility.

Electrowaves Electronics stated that the financial support will assist in expanding its manufacturing capacity and advancing its EV charging products.

The initiative marks another step in TDB’s ongoing efforts to back indigenous technology development under national programmes related to next-generation transportation systems.
