Exicom makes India’s first liquid-cooled EV charger modules

Exicom Tele-Systems on Wednesday announced the start of manufacturing liquid-cooled AC and DC power modules for EV chargers at its Hyderabad facility, making it the first company in India to manufacture this category of power electronics for global markets.

The company said the move will strengthen its India manufacturing base while supporting exports to North America and Europe. The modules will initially be used in Tritium’s DC charging portfolio, including its TRI-FLEX ultra-fast DC chargers and DC-FLEX charging systems.

Exicom said liquid cooling addresses one of the key challenges in high-power EV charging — heat. According to the company, nearly 60% of power electronics failures are linked to thermal stress, while a 10°C-15°C increase in temperature can double component failure rates.

Liquid-cooled systems use coolant to transfer heat more efficiently than air-cooled systems and can keep internal temperatures around 10°C lower, Exicom said. The sealed architecture also protects components from dust, moisture and salt air.

Exicom expands high-power charging portfolio

The initial production will primarily cater to customers in North America and Europe. The company plans to subsequently use the technology across its EV charging products for Charge Point Operators, fleets and OEMs in India.

Exicom also plans to incorporate liquid-cooled architecture into its flagship Harmony DC chargers over time. This could create a new line of power electronics exports from India.

The company said the technology builds on the liquid-cooled capabilities of Tritium, the global DC fast-charging company acquired by Exicom in 2024.

Anant Nahata, CEO and Managing Director, Exicom, said, “Anyone who has stood next to a fast charger on a 45-degree afternoon knows what heat does to electronics. EV Charging is getting faster with chargers running more hours a day, and customers expect them to work every season and at every site. Globally, liquid cooling has become the architecture of choice for high-power charging. We are bringing this technology to India. Local manufacturing matters because we now own more of that technology ourselves. We can engineer it, improve it and adapt it faster, for our customers here and across the world.”

Hyderabad facility to drive production

Exicom will manufacture the modules at its recently inaugurated Hyderabad Smart Manufacturing Facility.

The facility uses automation, digital traceability and specialised testing systems. The company said the plant will support production for both domestic and international markets.

The development also deepens the integration between Exicom and Tritium, with the company combining Tritium’s technology with Exicom’s manufacturing capabilities to develop and produce EV charging equipment in India.
