Exicom takes liquid-cooled EV charging technology from India to global markets

Exicom Tele-Systems Limited (BSE: 544133 | NSE: EXICOM) has begun manufacturing advanced liquid-cooled AC and DC power modules at its Hyderabad Smart Manufacturing Facility, making it the first company in India to produce this class of liquid-cooled power electronics for global markets.

The development strengthens Exicom’s ambition to establish India as a global base for technology-forward manufacturing, while advancing its long-term product roadmap and creating greater scope for high-value exports. It also reinforces the company’s positioning as a design-led manufacturer.

Thermal management is becoming increasingly critical as EV charging grows faster and chargers operate for longer periods. Reliability studies attribute nearly 60% of power electronics failures to thermal stress, with every 10°-15°C rise in temperature doubling components’ failure rate.

Liquid cooling tackles the challenge at source. Liquid coolant absorbs and transfers heat more effectively, keeping internal temperatures roughly 10°C lower than air-cooled systems. Building on Tritium’s in-house liquid-cooled capability, Exicom is bringing this globally proven high-power charging architecture into Indian manufacturing.

The liquid-cooled modules have been refined across some of the world’s toughest charging environments. They can pack more power into a compact footprint, operate continuously at high loads and cost less to operate over their lifetime. Their fully sealed design also helps keep out dust, moisture and salt air, protecting against conditions that can shorten charger life in the field.

Initial production will primarily serve North America and Europe, supporting Tritium’s DC charger portfolio, including TRI-FLEX™ ultra-fast DC chargers and DC-FLEX™ charging systems. Subsequent phases will bring the technology closer to Exicom’s customers, including Charge Point Operators, Fleets and OEMs, as Tritium’s range of DC fast chargers is now being deployed in India.

Over time, liquid-cooled architecture will be designed into Exicom’s flagship Harmony DC chargers, opening a new line of high-value power electronics exports from India.

Commenting on the development, 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.”

Exicom’s recently inaugurated Hyderabad Smart Manufacturing Facility, equipped with advanced automation, digital traceability and specialised testing, will manufacture the modules for domestic and international markets.

The move also deepens Exicom’s integration with Tritium, the global DC fast charging company it acquired in 2024, with technology and manufacturing synergies now working together to build advanced EV charging technology in India and for the world.
