Exicom Builds Liquid-Cooled Charger Modules in Hyderabad
Exicom says its Hyderabad plant is the first in India making liquid-cooled AC and DC power modules for export, with early output heading into Tritium DC fast chargers sold in North America and Europe.
Exicom has begun manufacturing liquid-cooled AC and DC power modules at its Hyderabad Smart Manufacturing Facility, saying it is the first company in India to build this class of power electronics for global markets, with initial output bound mainly for North America and Europe to be fitted into Tritium’s DC charger portfolio.
Exicom has begun turning out liquid-cooled AC and DC power modules at its Hyderabad Smart Manufacturing Facility, and says no other company in India has built this class of power electronics for global markets before. The first units are earmarked mainly for North America and Europe, where they will be fitted into the DC charger portfolio of Tritium, the fast-charging hardware brand Exicom now owns.
The detail matters more than it sounds. A DC fast charger is, stripped back, a cabinet full of power modules that convert grid AC into the high-voltage DC an electric vehicle battery can accept. Those modules are the single most expensive and most failure-prone part of the machine. Whoever makes them competitively controls the economics of the whole charger.
Why liquid cooling is the dividing line in charger hardware
Power modules generate heat, and heat is what limits how much current a charger can push and how long the electronics survive. Air-cooled designs move that heat with fans, which means intake vents, dust, insects, salt air and filters that need servicing. Liquid cooling circulates coolant through a sealed loop instead, letting the module be closed to the outside world.
The practical consequences are the ones charge point operators care about. Sealed enclosures tolerate coastal humidity, desert dust and roadside grime far better. Fan noise, a real constraint at urban and retail sites, largely disappears. And because heat is removed more efficiently, more power can be packed into the same cabinet footprint — the direction the whole industry is moving as passenger vehicles adopt higher-voltage architectures and as trucks and buses arrive with charging demands that dwarf a family car’s.
Liquid-cooled module production has, until now, been concentrated in a handful of places, overwhelmingly China and to a lesser degree Europe. Adding a qualified Indian source changes the shape of the map rather than the size of it.
What owning Tritium gives Exicom that a component supplier lacks
Most power electronics makers sell into charger OEMs and take whatever margin the buyer allows. Exicom sits on both sides of that transaction: it makes the module and it owns the brand that sells the finished charger. Tritium’s installed base and product line in North America and Europe give the Hyderabad output a guaranteed first customer, which is the hardest thing to secure when you are commissioning a new line in a new product category.
Vertical integration also compresses the qualification cycle. Getting a new module design accepted by an outside charger OEM typically means months of testing, safety certification and field trials before a single unit ships. When the module maker and the charger maker are the same company, that loop runs internally and on the company’s own schedule. As Charged EVs reported, the first modules off the Hyderabad line are already destined for the Tritium range rather than sitting in inventory waiting for a buyer.
There is a defensive logic too. Tritium’s history as a standalone charger business was shaped in part by supply chain exposure — components sourced abroad, priced in other currencies, delivered on other people’s lead times. Bringing module manufacture in-house and onshore to India removes a layer of that risk.
India as an export base, not just a domestic market
The framing of this announcement is deliberately outward-facing. The modules are not primarily for Indian charging networks; they are for North America and Europe. That positions Hyderabad as an export node in the global charging supply chain rather than as a plant serving a protected home market.
The modules are not primarily for Indian charging networks; they are for North America and Europe.
It fits a broader pattern in Indian electrification manufacturing, where the country’s cell-making capacity still lags badly but power electronics, inverters, motor controllers and charging hardware have proved a more approachable entry point. Cells require enormous capital, years of process learning and secured raw material streams. Power modules require engineering talent, precision assembly and test capability — resources India has in greater supply.
For buyers in the United States and the European Union, a non-Chinese source of liquid-cooled modules has value beyond price. Charging infrastructure procurement in both markets increasingly carries content, security and origin conditions attached to public money. A module built in India and installed in a charger sold under a Western brand answers a question that procurement officers have been asking with growing insistence.
The cost question nobody has answered yet
Whether this actually lowers the delivered cost of a DC fast charger is not established by the announcement, and it would be wrong to assume it. Indian labour costs are lower than Western ones, but power module cost is dominated by semiconductors, magnetics and capacitors — components bought on world markets at world prices. Freight from Hyderabad to a North American depot is longer and dearer than from a plant in Europe or Mexico. Tariff treatment is its own variable and shifting.
What a new source does reliably deliver is optionality. Charge point operators have spent the last several years complaining about lead times and about the reliability of installed hardware, and much of the reliability complaint traces back to thermal management and to the modules themselves. A sealed, liquid-cooled design manufactured by the company that also stands behind the charger warranty aligns incentives in a way that a purely arms-length supply relationship does not.
What to watch from here
Three things will tell you whether this is a genuine shift or a press milestone. First, volume: a line that has “started” production is not the same as a line running at rate, and the ramp curve is what determines whether Tritium can quote competitive lead times. Second, third-party sales — if Exicom eventually sells these modules to charger makers other than its own subsidiary, that is the market validating the product rather than a parent company absorbing it. Third, field performance: liquid cooling promises longer service life, and that claim is only settled after several years of installed units in real weather.
Against a wider backdrop, the announcement lands while equity markets remain firm. The S&P 500 tracker (NYSEARCA: SPY) closed at $765.72, up 0.41% on the session as of 20:00 GMT on 21 August 2026, with the Nasdaq 100 proxy at $713.44 and the Dow tracker at $532.22. Exicom and Tritium are not the drivers of that tape, but the capital environment for building out charging hardware capacity is meaningfully easier when it looks like this than when it does not.

Frequently asked questions
What exactly is Exicom now making in Hyderabad?
Exicom has started manufacturing liquid-cooled AC and DC power modules at its Hyderabad Smart Manufacturing Facility. Power modules are the electronics inside an EV charger that convert grid alternating current into the high-voltage direct current a vehicle battery accepts. The company says it is the first in India to build this class of power electronics for global markets.
Where are the first modules going?
The initial output is destined mainly for North America and Europe. Those modules will be fitted into the DC charger portfolio of Tritium, the fast-charging hardware brand that Exicom owns. That gives the new production line a built-in first customer rather than requiring Exicom to win external orders before shipping.
Why does liquid cooling matter for EV chargers?
Liquid cooling circulates coolant through a sealed loop instead of using fans and air vents. That keeps dust, moisture and salt air out of the electronics, cuts noise at urban and retail charging sites, and removes heat more efficiently — allowing more power to be packed into the same cabinet, which matters as vehicles and trucks demand faster charging.
Does Indian production make fast chargers cheaper?
Not automatically. Power module cost is dominated by semiconductors, magnetics and capacitors bought at world prices, and freight from India to North America is longer than from Europe or Mexico. Lower labour cost helps, but tariffs and shipping offset some of it. The clearer benefit is supply optionality and a non-Chinese source of this hardware.
Why does owning Tritium change Exicom’s position?
Component suppliers usually sell into charger makers and accept whatever margin the buyer allows. Exicom makes the module and owns the charger brand, so it captures value at both stages and can qualify new module designs internally rather than waiting months for an outside OEM’s testing, certification and field trial process to conclude.
What should observers watch next?
Three markers: whether the Hyderabad line reaches full production rate rather than merely starting, whether Exicom eventually sells these modules to charger makers other than Tritium, and how the units perform in the field over several years. Liquid cooling’s durability advantage is a claim that only real-world installations across seasons can settle.
