Tritium Unveils TRI-FLEX Scaling EV Charging Platform At ACT Expo 2025
Tritium unveiled its revolutionary TRI-FLEX charging platform at ACT Expo 2025
This year's Advanced Clean Transportation Expo, or ACT Expo 2025, is underway in Anaheim, California, with original equipment manufacturers (OEMs) and suppliers unveiling the latest advanced vehicles, low-carbon fuels, and innovative transportation technologies and services. Tritium, a global leader in DC fast chargers for electric vehicles (EVs), is using the event to announce its revolutionary TRI-FLEX charging platform—a next-generation distributed architecture that enables charge point operators to scale from four up to 64 charge points easily.
The technology promises to address critical infrastructure challenges as the EV market transitions from early adoption to mainstream over the next several years. 'Today marks a paradigm shift in EV charging infrastructure," said Arcady Sosinov, Tritium's CEO, during the unveiling at ACT Expo. "TRI-FLEX is not just an incremental improvement but a fundamental reimagining of distributed charging architecture designed to scale efficiently at the speed of coming demand in the market."
The TRI-FLEX hub—the core of the platform—is a power conversion system that scales from 400kW to 1.6MW of AC power and up to 3.2MW of DC power (a single Hub can power two to 32 TRI-FLEX dispensers—up to 64 charge points). Flexibility allows mixing and matching 100kW, 200kW, and 400kW dispensers in a single system, and the system's 25kW power resolution with real-time load balancing optimizes energy distribution. The TRI-FLEX hub carries a full IP65 environmental rating and advanced liquid cooling, maintaining reliable performance from Arctic cold (-35°C) to desert heat (+55°C).
I interviewed Sosinov to learn more about the technology, better understand why the company feels the market is ready, and understand its impact on consumers, the end users:
'Think of traditional charging like having separate water heaters for every shower in your house – inefficient, expensive, and difficult to scale. TRI-FLEX is like one smart water heater serving many showers simultaneously, giving each precisely the temperature and pressure it needs. We call it 'distributed' charging infrastructure, and Tritium pioneered it over a decade ago.
"TRI-FLEX dramatically enhances distributed charging: whereas existing charging systems typically only scale to 8 charging points, TRI-FLEX can scale to 64. That's eight times more charging points without requiring eight times the grid capacity. Our ultra-scaling architecture will support up to 64 vehicles from a single power system without requiring massive, costly and time-consuming grid upgrades. And best of all, customers can invest in a smaller system today and then scale to 64 charging points over time in a cost-effective way, without requiring new infrastructure or power cabinets (just add dispensers!).
"This isn't incremental improvement—it's a fundamental reimagining of what's possible in EV charging. Start with what you need today, scale seamlessly as demand grows—without replacing your initial investment. That's the promise of TRI-FLEX.'
'We're at a pivotal moment in transportation history. The EV market is going to surge from early adoption to mainstream acceptance, with global sales of EVs set to hit 20% of all vehicles this year. By 2030, we're looking at 27 million EVs on U.S. roads alone, and a staggering 92 million by 2040. This isn't gradual growth – it's an electric avalanche.
"Here's the challenge: today's charging infrastructure was built for yesterday's EV market. Current systems typically only scale to 8 charging points per power cabinet, require massive grid upgrades for expansion, and can't efficiently serve the growing diversity of vehicles from compact cars to commercial trucks.
"The coming EV revolution can only move at the speed of its infrastructure. Without a fundamental shift in charging architecture, we'll hit a wall where EVs are increasingly popular but increasingly difficult to charge. TRI-FLEX removes this final barrier between early adoption and mainstream electrification, ensuring the infrastructure can actually keep pace with growing demand for a diverse set of electric vehicles.'
'Absolutely, customers can replace their existing charging infrastructure with TRI-FLEX, without upgrading their grid connection. That allows them to scale from 4 charging points to 64 charging points over time.
"TRI-FLEX also has industry-leading power density of 512kW per square meter, which means it requires significantly less space than conventional systems. This is transformative for existing sites with limited real estate.
"We're giving operators a clear upgrade path that transforms their sites gradually, responding to actual demand rather than speculation. No more "build it and hope they come" – just smart infrastructure that grows precisely when and how it's needed.'
'For EV drivers, this is about eliminating the last vestiges of range anxiety. Going forward, the biggest pain point won't be vehicle range – it will be finding available chargers when and where you need them. TRI-FLEX changes that equation by allowing for fast, cost-effective scaling of EV charging locations that can keep up with accelerating demand.
"With up to 64 charging connections from a single system, the likelihood of waiting in line plummets. Our technology enables charging operators to install many more charging points in the same space with the same grid connection, dramatically increasing availability.
"As the EV charging network expands into more diverse locations, reliability in extreme environments becomes crucial. Our fully sealed IP65-rated enclosures and advanced liquid cooling technology ensure consistent performance from Arctic cold to desert heat. This means TRI-FLEX will work in places where conventional chargers struggle but where drivers absolutely need dependable charging. When other systems might shut down in Phoenix's summer heat or Minneapolis's winter freeze, TRI-FLEX keeps delivering power.'
'This next-generation architecture has several patents pending. We've developed truly innovative approaches to power sharing, thermal management, and system integration that represent significant advances in the state of the art. The intellectual property portfolio we're building around TRI-FLEX will help secure Tritium's position at the forefront of charging technology for years to come.
"We're taking orders today and expect to begin shipping next quarter. TRI-FLEX addresses the most pressing infrastructure challenges for charge point operators, fleet managers, and retail site developers, allowing for increased return on investment (ROI) and lower total cost of ownership (TCO).
"It's worth remembering that Tritium has been a pioneer in DC fast charging for over a decade now. TRI-FLEX is just our latest innovation to keep powering the road forward.'

Waymos are being torched in LA. Why burning EVs isn't a good idea.
Waymos are being torched in LA. Why burning EVs isn't a good idea. Waymo taxis were set on fire during L.A. protests. It's unclear whether they were called or if protesters simply took advantage of their presence Show Caption Hide Caption Protesters set Waymo cars on fire in Los Angeles anti-ICE protests Footage showed flames and thick smoke as demonstrators set Waymo cars on fire during an anti-ICE protest in Los Angeles on Sunday afternoon. Multiple Waymo self-driving robotaxis were set on fire in Los Angeles during protests there. Other cars were also put to the torch but the Waymos have garnered special interest, partially because they're something new on the scene and partially because as electric vehicles, they raise different and specific concerns if their batteries burn. Here's what we know and what experts worry about. How many Waymos burned? From social media and photos, it appears that at least five Waymo self-driving robotaxis were set on fire on Sunday, June 8 amidst immigration protests in downtown Los Angeles. Protesters smashed windows on the cars – all Jaguar I-PACE electric SUVs – as well as spray painting them with anti-ICE and anti-Trump slogans. Some were also set on fire. The burning cars, whose base sticker price is $73,000, according to Car and Driver, sent plumes of thick black smoke billowing into the blue Los Angeles sky, making for stunning photos that have figured prominently in many media feeds about the protests. What's Waymo doing about the attacks on its cars? Waymo has suspended service to the affected area of downtown Los Angeles. A Waymo spokesperson told USA TODAY on Monday morning, June 9, the company has removed its vehicles from downtown Los Angeles and is currently not serving the area "out of an abundance of caution." The spokesperson said the company is still operating in Los Angeles, which covers 500 square miles, and is working in coordination with the Los Angeles Police Department. What other cities have Waymos? Waymo are available for rides in Austin, Phoenix, Los Angeles, parts of Silicon Valley and all of San Francisco. They're expected to start in Atlanta, Miami and Washington in 2026. In April the company announced its first foreign venture, with testing beginning in Tokyo. According to the company, more than 250,000 trips a week are taken in its driverless robotaxis. Waymo is owned by Google's parent company, Alphabet. Are people targeting Waymos specifically? It's not clear if the Los Angeles protesters were specifically targeting Waymos or if the cars just happened to wander into the area and because they have no drivers, they were perceived as more vulnerable or they simply didn't know to drive away. The Waymos that burned all appeared to be empty, meaning no passengers were potentially at risk. There have been suggestions online that protesters might have called Waymos to the area specifically to set them on fire. However that would mean Waymo would know the name and contact info of the people who'd called them, making the scenario less likely though certainly not impossible. Waymo would not say how its cars came to be in the area. There have also been suggestions that the Waymos were targeted because they are festooned with cameras, meaning they might be used to identify protesters engaging in illegal activity. However many modern cars are equipped with cameras, so Waymos aren't that different from most newer vehicles on the road. In cities where Waymos are available, which include San Francisco, Los Angeles, Austin and Phoenix, the cars are very much like human-driven taxis. They're a frequent sight as they drive around on their way to pick up passengers, or to park as they wait for their next ride request. That means they're often wandering around on city streets, especially in popular and busy areas – like downtown Los Angeles. So it's quite possible the Waymos that were attacked were just going about their business and happened to be in the wrong place at the wrong time. It's also true that Waymos are very conservative in their driving habits and won't drive threateningly if surrounded by people. So while a human driver might rev their motor or honk or drive aggressively to get out of a potentially dangerous situation, a Waymo would just calmly try to go on its way – making it an easy target. What happens when an EV burns? Electric vehicle fires can burn hotter and more intensely than gasoline-fueled cars, if their batteries catch fire. This can happen if they are crashed or if their batteries are infiltrated with saltwater, as can happen to cars nears the coast during hurricanes and flooding events. If an electric vehicle's battery is damaged by a collision or water intrusion, a short circuit can occur, which causes the cell to discharge energy and heat up. This can lead to an event called 'thermal runaway,' in which the heat propagates from one cell to the next, causing them to burn. Heat generated from a fire, thermal runaway of an adjacent cell, or shorting of the battery can melt the porous membrane between the battery's cathode and anode, causing this cell to go into thermal runaway. The heat causes the cell to vent flammable gas, which can ignite and catch fire, which can cause a chain reaction. Is a burning car a health hazard? There are important distinctions between electric vehicle (EV) fires and traditional gasoline-powered vehicle fires, both in terms of combustion characteristics and potential health hazards, said Dr. Alberto Caban-Martinez, deputy director of the Sylvester Firefighter Cancer Initiative at the University of Miami Miller School of Medicine. EV fires can release gases such as hydrogen fluoride, carbon monoxide, volatile organic compounds, and metal-based particulates. 'These emissions differ in composition from those generated by gasoline combustion, which primarily include carbon monoxide, benzene, and other hydrocarbons,' he said. The health concerns from EV fires arise for anyone nearby, particularly bystanders downwind of the smoke plume who may inhale toxic combustion byproducts, Caban-Martinez said. But firefighters are at special risk due to the frequency and intensity of their exposure to EV fires. 'Firefighters often work in close proximity to the fire, are involved in prolonged suppression and overhaul tasks, and may experience cumulative exposure over the course of their careers. Repeated exposures, even at low doses to hazardous substances released during EV fires can increase the risk of long-term health effects, including respiratory disease and cancer,' Caban-Martinez said. Putting out a fire in an electric vehicle requires different techniques If an electric vehicle's battery catches fire, different firefighting techniques can be required to quench it. Firefighters are trained on these techniques and the National Fire Protection Association offers emergency response guides to most alternative fuel vehicles. Today most EVs are built with what are known as "cut loops" or "first responder loops" that allow firefighters and first responders to easily cut and disconnect the high-voltage system outside of the high voltage battery, to reduce the risk of electric shock and possible fire. Note: this can only be done safely by trained professionals with the appropriate tools and gear. EV fires are more difficult to put out than ones in gasoline-powered cars and require different firefighting techniques, which firefighters are trained on. The biggest difference is that an EV battery fire cannot be put out with the type of firefighting foam used to smother other fires. If an EV battery is on fire, it does not require oxygen to burn because it is self-sustaining, so the foam cannot stop the fire. Instead, the battery must be cooled to stop the fire and end thermal runaway. One technique is to use special "pancake nozzles" that can slide underneath the vehicle to spray water on the bottom of the battery box, though these require large amounts of water.

Threats to Tesla's revenue are piling up
Tesla faces fresh risks to a big income stream: sales of regulatory credits to other automakers under vehicle emissions and efficiency rules. Why it matters: Tesla's credit sales were $595 million last quarter and totaled $3.36 billion in the five quarters through Q1 of 2025. The credits are awarded to companies like Tesla that exceed emissions standards. Producers of gas-powered vehicles buy them to help meet various CO2 and mileage standards. The latest: Republicans on the Senate's commerce committee late last week proposed ending civil penalties under the Transportation Department's fuel economy rules. It's part of the committee's portion of the budget "reconciliation" bill — the top GOP and White House legislative priority. The provision would "modestly" cut auto prices by ending penalties on automakers that now "design cars to conform to the wishes of DC bureaucrats rather than consumers," a GOP summary states. The intrigue:"This Senate action would effectively end the market for CAFE credits," Chris Harto, a senior policy analyst at Consumer Reports, tells Axios via email. Dan Becker, who heads the Safe Climate Transport Campaign at the Center for Biological Diversity, noted: "Why buy credits if Trump gives you a get out of CAFE free card?" Driving the news: Separately, DOT on Friday issued an "interpretive rule" that bars consideration of EVs when it sets these mileage rules. It's a step toward crafting replacement standards, DOT said. This paves the way for less aggressive requirements — and less need for buying credits. State of play: Several buckets of credits benefit Tesla, the dominant U.S. EV seller. EPA emissions standards, Transportation Department fuel economy mandates, and California's ambitious clean cars program all provide opportunities. European emissions rules also generate credits. The big picture: The regulatory credit market was already facing risks before all the news late last week. EPA is planning to rescind Biden-era EPA carbon emissions rules for model years 2027 and onward. The House-passed reconciliation bill and the Senate GOP proposal would also nix them. And the House bill pulls back Biden-era DOT mileage rules. Both chambers have passed measures that end EPA's approval of California's auto emissions rules. Threat level: Potential loss of credit revenues comes at a perilous time for Tesla. Its sales have slumped in recent quarters, and CEO Elon Musk's rightward turn and alliance with Trump are among the reasons why, analysts say. The House plan ends $7,500 consumer purchase subsidies for EVs under the Democrats' 2022 Inflation Reduction Act. By the numbers: Credit revenues exceeded Tesla's overall profit last quarter — in other words, it would have been in the red without them. Yes, Q1 was atypically weak for Tesla, but consider Q4 of 2024, when Tesla reported $2.13 billion in profits that were helped along by $692 million in credit sales. In Q3, those numbers were $2.17B and $739M, respectively. Friction point: More broadly, the meltdown of Tesla CEO Elon Musk's relationship with Trump also creates new and unpredictable risks for the billionaire entrepreneur's business empire.
