Exicom Starts Manufacturing Liquid-Cooled EV Charger Modules at Hyderabad Plant

Exicom Tele-Systems has begun manufacturing liquid-cooled AC and DC power modules for electric vehicle chargers at its manufacturing facility in Hyderabad, a move the company says makes it the first manufacturer in India to produce this category of power electronics for export markets.

The claim, made by Anshuman Divyanshu, chief executive of Exicom's EVSE business, has not been independently verified, though no rival Indian charger maker appears to have brought liquid-cooled power modules into domestic production so far. Exicom, listed on the BSE and NSE, is India's largest maker of EV chargers by volume and has expanded aggressively since acquiring the Australian fast-charging firm Tritium in 2024.

The new modules will initially supply Tritium's DC fast-charger range, including its TRI-FLEX platform, for customers in North America and Europe. Divyanshu said the project cost about $3.5 million and took nearly two years to develop, with engineering input from teams in India, Brisbane and the United States, while manufacturing is carried out entirely at the Hyderabad site.

Liquid cooling matters because heat is the principal cause of failure in power electronics. Industry studies, including long-standing US Air Force reliability research, have found that temperature-related stress accounts for more than half of such failures, and that failure rates roughly double for every 10-15°C rise in operating temperature. As charger output climbs towards 350 kilowatts and beyond, air cooling struggles to dissipate heat efficiently, particularly in hot climates such as India's, prompting global manufacturers to shift towards liquid-cooled architecture for high-power installations.

Exicom says its liquid-cooled modules run at efficiencies of up to 99 per cent, against roughly 95-96 per cent for air-cooled equivalents, and carry a ten-year warranty compared with about two years typically offered on air-cooled units. The modules cost roughly twice as much to build, the company said, but are expected to lower total ownership costs over their lifetime.

The Hyderabad facility, inaugurated in March this year with an investment of ₹216 crore, has more than doubled Exicom's production capacity in its first phase and employs over 750 people. It manufactures for both Exicom's own Harmony line of DC fast chargers and Tritium's international portfolio.

The launch comes as India's charging infrastructure expands rapidly but unevenly. The country had 52,718 public charging points, including 16,561 fast chargers, as of July, according to government data presented in Parliament, still well short of global benchmarks for chargers per electric vehicle. Divyanshu expects domestic demand for liquid-cooled units to remain limited for now, with about 95 per cent of chargers sold in India likely to stay air-cooled over the next two years, even as export orders grow.

For Exicom, which posted a sharp revenue recovery in the June quarter after a weak previous year, the move signals an attempt to position Indian manufacturing higher up the value chain in global EV charging hardware, rather than compete solely on volume.
