The rapid evolution of electric vehicles has introduced new challenges for high-voltage circuit protection. Traditional solutions, such as fuses and pyrotechnic devices, are single use, leaving OEMs and fleet operators facing costly component replacements, extended downtime, and even full battery pack swaps after minor fault events.

Breaktor® circuit protection technology changes this paradigm. By combining protection and switching into a single, resettable device, Breaktor eliminates the need for disposable components and reduces service complexity. Its single-pole form factor simplifies integration, while resetability ensures continued operation until planned maintenance—improving reliability, reducing waste, and lowering total cost of ownership.

Join this webinar at our March Virtual Conference on EV Engineering, presented by Eaton, to learn how Breaktor is redefining EV circuit protection and delivering smarter, more sustainable solutions for next-generation architectures.

Ampere, Renault Group’s EV and software unit, has signed a joint development agreement with Basquevolt to accelerate development and validation of lithium metal-based batteries aimed at meeting “Pre-A Sample” EV prototype requirements.

Basquevolt says its lithium metal-based technology—combining a polymer electrolyte with an advanced anode—could deliver a major jump in energy density compared with today’s liquid-electrolyte lithium-ion batteries. The companies also pointed to potential benefits including improved thermal stability and fast-charging capability, enabling more compact and lightweight packs.

The partners said the goal is to validate performance in real-world automotive conditions and move the technology toward commercial deployment in electric vehicles.

“Entering this next phase with Ampere marks a major milestone in our mission to bring polymer electrolyte technology closer to the mass market,” said Basquevolt CEO Pablo Fernández. Ampere VP Nicolas Racquet said the work will focus on “validating performance in real-world automotive conditions.”

Basquevolt also claimed its polymer electrolyte approach could simplify manufacturing, translating into about 30% lower capital investment per GWh and 30% less energy used per kWh produced compared with conventional gigafactory processes.

NoMIS Power has released two new medium-voltage silicon carbide MOSFETs, including its first 1.7 kV device, targeting applications such as grid infrastructure, rail and heavy-duty electrification, industrial drives and marine systems.

The new parts are the N3PT035MP330K (3.3 kV, 35 mΩ, 88 A) and the N3PT100MP170K (1.7 kV, 100 mΩ, 24 A). Both can be sampled in TO-247-4L packages or as bare die. NoMIS says the devices are built on its next-generation planar SiC platform, intended to extend performance from its 1.2 kV MOSFETs into the 1.7 kV and 3.3 kV classes for higher efficiency and higher-frequency operation.

NoMIS is positioning the 1.7 kV MOSFET as a bridge between established 1.2 kV designs and 3.3 kV architectures, enabling efficient power stages around ~1.0 kV-class DC buses used in traction auxiliaries, charging subsystems and industrial power supplies. The company also highlighted operation up to 175°C, +18 V and +20 V gate-drive compatibility, higher dv/dt capability and improved efficiency–ruggedness tradeoffs.

“This is our first 1.7 kV offering—an important transitory node that bridges established 1.2 kV designs to 3.3 kV architectures,” said NoMIS co-founder and CEO Adam Morgan.

Tellus Power aims to deliver the features customers need today, while preparing for a massive scaling up in the future.

It’s tough to keep up with the latest developments in the EV fast charging industry these days. Charging providers are rapidly rolling out fast charging stations around the world, with ever-larger numbers of individual charging points.

At the same time, technical innovations are moving fast, and operators and hardware manufacturers don’t necessarily agree on the most cost-effective and customer-friendly ways to scale fast charging.

Everyone agrees that the industry needs cost-effective ways to scale up to larger sites and more coverage, but is it better to use standalone chargers that incorporate the customer interface and the power supply in a single unit, or to use a distributed system with a central power supply and satellite dispensers?

Everyone agrees that user interfaces need to be better—we’re all sick and tired of the proliferation of proprietary, poorly-designed apps. But are credit card readers (mandated in some jurisdictions) the answer, or are they anachronistic devices that introduce another point of failure? And why is it taking so long to get Plug & Charge rolled out?

Tellus Power is attempting to cover all the bases. The company recently unveiled two new 600 kW DC fast charger systems: a distributed system and an all-in-one unit. Both configurations support 800-volt architecture, and both are compatible with NACS, CCS1 and CCS2 standards.

Charged spoke with Tellus Power CEO Mike Calise, who has been running the company since the beginning of 2025.

Charged: Let’s start with a brief history of the company and an overview of what you do.

Mike Calise:Tellus Power is a manufacturer of DC fast chargers and vehicle-to-grid hardware, and a supplier of software and storage products, which are critical for grid-friendly infrastructure. 

We have our roots in Shanghai, so world-class, low-cost global manufacturing. We have our headquarters in Irvine, California, where we also manufacture DC fast chargers. We manufacture what’s required for Build America, Buy America products—55% US content delivering to the US market. We also have offices in India, Europe, South America and the Southeast Asian market.

We are in a record time for DC fast charging deployments. The opportunities are exceptional. We see Uber and Lyft requiring very fast in and out times, we’re seeing last-mile delivery fleets electrifying, we’re seeing the advent of medium-duty and heavy-duty electric trucks. 

Our mission is to be number one, two or three in all our markets.

Charged: You have a pair of new products—a distributed charger and a standalone charger. I recently spoke with a couple of people who say that distributed chargers are the future, but you see good applications for both formats. Where would you want a distributed setup and where would you want a standalone? 

Mike Calise: I love the question, and they are correct to say that distributed charging is the future. Well, it was the early present too. Think about Tesla. Tesla was such a streamlined experience. You show up, you plug in and you walk away. You don’t see any big unit, you don’t see a big screen, you don’t see a credit card reader.

But we as a nation went with CCS1, so you have to meet the needs of every EV owner. You need to put a credit card reader on there. Obviously, you need a display to interact. We needed to put those units in to meet a large cross-section of the population’s different driving habits. 

Sometimes bigger is better. If you can physically see a unit that’s lit up, you can clearly see where you can get your charge. The trick with standalone integrated solutions is make them with a small enough footprint that they’ll fit behind the parking stall. Then you just plop them down—easy to install and easy to maintain. You got one down, electrician shows up, opens up the cabinet, everything is there—the power, the DC, the AC, the rectification, the cable.

So, there is practical benefit to the all-in-one. And if you look at us and our competition, we’re still selling a lot of all-in-one units. But is distributed charging the future? We believe it is. Why? Because ideally, everybody is feeling that Tesla experience. You show up, there’s a little pedestal, you plug it in, you walk away. The car transacts using Plug & Charge, your credit card or your loyalty program. It’s seamless. No displays, no credit card swipes. Who doesn’t want to streamline? 

If you think of the old mainframe businesses and computers, distributed processing is where everything eventually went to. You could say, well, that big power cabinet with those little terminals, that’s almost like a mainframe, right? But the bottom line is the processing—it’s all in the cloud. It’s all in the car. And we’re already there with Plug & Charge. 

There are advantages to that sweet, small pedestal—no display that went bad, no credit card reader that got jammed. A lot of the downtime in these units is not charge-related, it’s display-related, it’s modem-related, it’s credit card-related. The charging isn’t the problem. Every now and then you’ve got to repair it, sure. But the things that fail are those human interface things—displays, buttons.

When we go to this distributed system, here’s another advantage. You’re distributing over a DC bus. If you go AC grid, rectification, AC to DC, then DC to DC in the car, you’ve got some hops there. When we distribute to pedestals, all of that is DC, so the cost of installation goes down dramatically. 

And if one of these units goes down, you just pop open the cabinet and replace an AC-to-DC module or a DC-to-DC module. You deal with the power conversion back at the cabinet, and that’s transformer-like equipment. That back-of-the-fence grid equipment, you don’t have to make it pretty, so you can keep the cost down. Then you make nice, streamlined, aesthetically pleasing pedestals to plug your car into.

Charged: Someone was telling me the other day that the credit card readers are the biggest point of failure, but aren’t they required in California and some other states?

Mike Calise: Mary Nichols [Chairwoman of the California Air Resources Board from 2007 to 2020], who drove the most EV-friendly policy in the country, said EVs cannot be just for the wealthy. EVs need to be accessible for everybody. We’re going to require a credit card. You can’t have someone show up and not get a charge because they weren’t sophisticated enough to get the app and put in a QR code. And she made a lot of sense. Who’s going to argue the equity? But we did, and here’s why. Turns out more people have cell phones than they do credit cards. From the disadvantaged neighborhoods all the way up, everyone has a cell phone. Not everyone has a credit card.

So, we appreciate the well-intended nature of that policy, but actually the credit cards are a mess. Credit cards are not as reliable in outdoor applications as they are in indoor applications. Those credit card readers, the modems, the SIM cards and the connectivity and the displays, they take a beating in the wild. They weren’t designed for abusive outdoor use, and they’re not even always covered. I believe California recently reversed the requirement.

[Editor’s note: Authority for EVSE standards is being transferred from CARB to the California Energy Commission. A CEC spokesman told Charged that a recently-passed bill, AB 1423, “authorizes the CEC to modify requirements for EV charger payment options in light of changing technologies or cost impacts,” and that the CEC is “exploring a process for new regulations.”]

With Plug & Charge, you don’t even need a credit card, an app or a cell phone. You just plug in, and your car does it all. Yes, you have to have a credit card account or some bank account—you can’t pay cash.

Charged: How far away are we from seeing widespread implementation of Plug & Charge?

Mike Calise: The Plug & Charge concept and the 15118 standard have been around for several years. It’s not that far out. It’s being used daily today.

Charged: I’d love to hear some more about V2G. Is V2G still a pilot-level technology, or are there some real commercial applications going on?

Mike Calise: There are some real useful projects going on today, so it’s no longer pilots only. We have Oakland Unified School District and Fremont Unified School District right now, using battery storage within the school bus, going back into the building and into stationary storage, which is awesome.

Check this story out, we’re very proud of it. They have very expensive petroleum in California that they have to purchase for these buses, making their operational costs prohibitive. Their utility bills are through the roof. They have energy-inefficient buildings, and some of these school districts are operating in the red due to high costs of operation.

The Oakland and Fremont school districts got local municipal funding for a V2G project. They put solar canopies on their parking lots, producing their own energy. Their energy bills went down a little bit. They deployed V2G-capable electric buses, and their overall utility and fuel bills went down dramatically. Now they’re operating in the black. They charge these buses during the nighttime when energy is cheap, then discharge the batteries from the vehicles to the building during times of peak energy costs. 

It’s a complete transformation for the school districts and a positive impact to their communities. That’s a model that can be scaled across a massive number of public school districts. 

Charged: So these school districts are not only paying for all their energy costs, but they’re actually generating a surplus that they can use to pay for other things? Why isn’t everybody doing this? 

Mike Calise: You need a lot of stakeholders. You need the utility—they’re critical because they’re going to transact the deal. You need a technology provider like Tellus Power. You need the bus company to say, we’re okay to run these batteries back and forth all day long, not just one way. And when you get all that, it happens. School buses are still the best application, but then you go to transit buses and last-mile delivery vehicles with known routes. If there are known routes, a known time, you can effectively manage it because you know when the sun will shine during the day, and you know the utility rates for time-of-use. You can then mitigate utility demand fees and even exploit dynamic pricing.  

It’s a killer application. Often it takes government grants because these buses are expensive, but we’re way past this phase of testing in the lab to real-world applications. Now you need a little bit of escape velocity—that’s probably in the next three years.

Charged: Well, don’t let the politicians find out about that, because then they’ll just cut the school budgets by the corresponding amount.

Mike Calise: Of course they will. Yeah, we’ve got to be apolitical, and I see the good, the bad and the ugly in multiple administrations. I’ve been through two Obama administrations, one Trump, one Biden, another Trump, and we’re still doing this business. Government grants are good, but even though they are often well-intended, sometimes there are unintended consequences, and it can get messy. So, we’re just talking about the technology and the value that we bring and the advantages we bring over our competitors as we navigate tailwinds and headwinds alike.

Charged: I hear a lot of people saying there’s going to be a big shakeout in the charging field. With so many companies selling chargers, how do you differentiate your products?

Mike Calise: Well, there’s already been a shakeout. There’s been failed companies since 2010. Littered on the highway, there’s probably 100 companies with chargers out there. I can name at least 20 that were around in the early days that looked incredibly promising but failed dramatically. That’s a natural course for all innovative new businesses. 

So, who are you going to deal with? The company that still survived after all these years, or the company that’s gone? I worked for both types. I’m the one who took Blink public back in 2018. The CEO rebranded it from Car Charging, took it public, and created a $2-billion valuation at one time. Right now, they’re around 180 million, depending on the day, and the stock is up over 50% in the last six months.

We’re in an innovative business. There’ll be successes, failures and consolidation along the way. As any experienced CEO will tell you, we get tailwinds and headwinds. Just like in sailboat racing. That’s what makes Tellus Power different—we know how to sail in both headwinds and tailwinds. You’ve got to know when to put up the sails without breaking the masts, and you’ve got to know when to get real light and reduce your load so you can go faster. This is a natural test for strong leadership.

The companies that will succeed are the ones that continue to innovate through an evolving new market, but sometimes innovation isn’t necessarily technology—it’s also the business model. How do you work with a revenue share? How do you work with leasing? How do you work with buy now, pay later? How do you work with percentages of revenue and energy? How do you secure cheaper energy? How do you store the energy that you secured? How do you create your own energy? How do you sell back energy? That’s a complex scenario. And the companies that we’ll see in the future are the companies that figure out that there’s money to be made in hardware, but there’s also money to be made in services, logistics, software, energy, tokenization of energy, and transferability of tokenized energy.

Charged: What are some other innovations that we’re going to see over the next few years in the fast charging sphere?

Mike Calise: What we’re going to see are efficiency plays within a microgrid. It’s a whole new world of increased load demand. It used to be that transportation was the biggest new load on the grid. Now it’s shifted to data centers and AI. We have a pressing demand for new, cleaner energy with these industries, and we’re starting to see massive shifts in the way energy production is handled because of those needs. 

We’re seeing new innovations in transformer technology using intelligent high-switch capability, which is very efficient transformer technology, excellent for the grid, silicon carbide-based. It’s going to be very important for overall grid efficiency. You start to see the reduction, the removal of these power conversion systems. The grid is AC, so we go from AC to DC, DC to AC, then we go to the DC battery pack, and you’ve got these systems in place that are expensive. So, you have your batteries and renewable energy which are DC, and then you have this system that’s doing all these conversions in a box. In the future, we’re going to get rid of that box, and even get rid of internal transformers. You’re going to have a microgrid that’s highly efficient, less lossy to the tune of…I’m guessing 94 or 95% efficient versus 91 or 92%, maybe as high as 97%. 

Everyone says we need this massive battery breakthrough so we can all charge up in five minutes, but you actually don’t need that. There’s sustainable innovation and there’s disruptive innovation. Sustainable innovation in battery technologies happens just by changing the anode chemistry or the structural costs associated with building the battery. Now we’re seeing battery technologies incrementally improved to the point where they’re at a $100/kWh price point. It’ll drop to $90, then it’ll continue to drop to $80.

If you’re at $80/kWh, you can basically manufacture a compact EV, the whole car, for less than $20,000. You can get a highly affordable commuter car for the masses, and with an innovative business model, you don’t even have to buy the car—you can rent it. Waymo and Tesla are exploring autonomous vehicles with new business models. The world will be a very different place in the next five years. I see technology drivers down at the silicon level that are going to unleash tremendous gains to deliver cost-effective solutions for EVs.

Battery metals recycling and refining firm Aqua Metals has signed a three-year material supply agreement with US-based cathode active materials (CAM) battery metals producer 6K Energy.

The agreement establishes a commercial framework for the future supply of battery-grade nickel metal and lithium carbonate produced using the AquaRefining process. AquaRefining operates without hydrogen peroxide or sodium hydroxide, regenerates sulfuric acid for reuse and produces zero sodium sulfate waste, creating a closed-loop system.

Aqua Metals and 6K Energy will align on product specifications, qualification pathways and index-based pricing mechanisms to support the use of recycled and refined battery materials in domestic cathode manufacturing.

Under the deal, 6K will have the option to purchase battery-grade nickel metal and lithium carbonate at prices based on London Metal Exchange trading prices at the time. The material volumes could represent tens of millions of dollars in annual battery-materials value, subject to qualification, market conditions, and scale-up.

The agreement is based on 6K completing its proposed battery material production facility and Aqua Metals completing an expanded recycling facility.

Materials supplied under the agreement are expected to meet Foreign Entity of Concern (FEOC) compliance requirements, supporting broader efforts to build secure, resilient and transparent domestic battery materials infrastructure.

The agreement also provides optionality for future collaboration, including the potential evaluation of tolling arrangements for lithium-ion battery black mass. This flexibility reinforces Aqua’s strategy to develop a feedstock-agnostic refining platform capable of supporting multiple battery chemistries, including nickel-based and lithium iron phosphate (LFP) systems, as the market continues to evolve.

“A reliable supply of high-purity, compliant battery materials is essential to scaling cathode manufacturing in the United States,” said Saurabh Ullal, President of 6K Energy. “This agreement with Aqua Metals creates a framework to evaluate and integrate recycled and refined nickel and lithium materials that meet our technical requirements while supporting our domestic sourcing objectives.”

Japan’s EXEDY has approved the acquisition of Protean Electric, a UK-based developer of in-wheel motors, in a move it says is aimed at strengthening its electrification technology portfolio as the auto industry shifts toward “CASE” (connected, autonomous, shared & services, electric).

Protean’s in-wheel motors—drive units integrated into the wheels—are positioned as a way to improve vehicle control via fast response and to increase design freedom. EXEDY also said the technology could influence conventional drivetrain architectures and help with control integration challenges often cited for software-defined vehicles.

EXEDY plans to acquire 9,086,213 shares for JPY 5.07 billion (about $35 million) plus an estimated JPY 100 million in advisory fees, for a total estimated outlay of JPY 5.17 billion. The seller is BD Auto and Energy, and EXEDY expects to sign and close on February 26, 2026.

“Protean Electric’s in-wheel motor technology is expected to contribute to improved vehicle control performance through fast response characteristics and to increase freedom in vehicle design,” the company said.

E-mobility companies in Africa are beginning to assemble electric vans and taxis locally, using Chinese-made kits, the Associated Press reports. Kenya and Nigeria, two of Africa’s largest economies, are leading the push for local EV assembly.

Lagos-based SAGLEV has begun assembling 18-seater electric passenger vans using imported kits supplied by Chinese automaker Dongfeng. The company says it plans to make up to 2,500 vehicles a year for Nigeria and other West African markets.

“This is a major step in Nigeria’s transition toward clean, fossil-free transportation,” said Saglev’s CEO Olu Falaye. “This feat is a clear signal that el ectric mobility in Nigeria is practical, scalable and ready for adoption.”

SAGLEV, a joint venture between Nigeria’s Stallion Group, a major auto distributor, and Chinese automaker Sokon Motor, also plans to install solar-powered charging stations to provide more reliable sources of power—a key challenge for EV adoption in much of Africa.

In Kenya, Chinese-backed Rideence Africa recently signed a $2.46-million deal with Mombasa-based Associated Vehicle Assemblers (AVA) to begin local assembly of electric taxis and minibuses from kits supplied by China’s Jiangsu Joylong Automobile and Beijing Henrey Automobile Technology.

“We are now moving decisively from operator to manufacturer,” said Rideence Africa’s Managing Director, Minnan Yu. “Our aim is to build a Kenya-rooted new-energy mobility company serving Africa.”

“The assembly of electric vans is emerging as a strong market segment,” said Dennis Wakaba, Secretary-General of the Electric Mobility Association of Kenya. “Earlier, the cost of electric vans was high, putting off operators. But as local assembly scales up, these costs have dropped, attracting more orders.”

Vans and minibuses are essential parts of public transport systems throughout Africa. Japanese models such as the Toyota Hiace have long dominated the market. But cutting consumption of expensive imported gasoline makes sense both for individual operators and national governments. According to the AP’s sources, the cost of driving an EV can be as low as a fifth the cost of burning petrol.

Ethiopia and South Africa also have entered the market. In Ethiopia, Belayneh Kinde Group (BKG) assembles about 150 minibuses a month using Chinese components.

Affordability is a big barrier to EV adoption in Africa—transport operators often have limited access to credit, and few can afford to purchase new vehicles outright.

To make EVs more affordable, companies like Rideence and BasiGo are adopting pay-as-you-drive and lease-to-own options.

“These innovative financing models mitigate risks for both assembler and operators, helping put vehicles on the road faster,” Wakaba said.

Electric utility Potomac Edison, a subsidiary of FirstEnergy that serves some 285,000 customers in Maryland, has received approval from the Maryland Public Service Commission to launch a pilot program aimed at helping local school systems transition to zero-emission school buses, EVinfo reports.

Maryland’s Climate Solutions Now Act of 2022 requires public school systems to purchase zero-emission vehicles. Potomac Edison aims to address one of the biggest barriers to EV adoption by covering the cost difference between diesel and electric buses (up to $250,000 per unit), along with the cost of charging infrastructure and any necessary electrical upgrades.

The $11.1-million pilot program will support the deployment of up to 28 electric school buses within Potomac Edison’s Maryland service territory, and will provide technical and administrative assistance to help school systems plan charging locations, install equipment and train personnel. The program will also include access to vehicle-to-grid technology, allowing Potomac Edison to evaluate how energy stored in bus batteries can be fed back to the grid when vehicles are not in use.

“This program is designed to help make [the EV] transition more practical and affordable,” said Jim Myers, FirstEnergy’s President of West Virginia and Maryland. “We’re reducing upfront costs and offering hands-on support to help school systems integrate electric buses smoothly. At the same time, we’re exploring how these buses can support grid reliability through innovative technology.”
