Swedish battery manufacturer Northvolt is taking its technology to the skies, announcing a new program surrounding lightweight, energy-dense lithium metal cells and modules to support electric aviation. The electric plane battery development is already underway through Northvolt’s subsidiary Cuberg, which has some milestones to share.
Northvolt was founded by two former Tesla executives following their time working at the American automaker’s first Gigafactory in Nevada alongside Panasonic. The initial goal of the company was to recreate the “gigafactory” concept in Scandinavia.

Less than a week after industry leader CATL shared details of a new condensed battery that may one day power electric planes, Northvolt has followed up with news of its own program.
The development process is led by Northvolt subsidiary Cuberg, which its parent says is closer than ever to delivering a fully-integrated lithium metal battery system, following validated performance data published last summer.
The development process toward scalable electric plane battery cells began with Cuberg’s 20 Ah commercial-format lithium metal pouch cell, which has already begun shipping to customers around the globe.
Cuberg then integrated those pouch cells into an aviation-specific battery module offering specific energy of 280 Wh/kg and an energy density of 320 Wh/L. For comparison, CATL’s aforementioned condensed cells are promising an energy density of 500 Wh/kg.
Northvolt relayed that Cuberg has already completed a runway verification test using the lithium metal module platform and achieved passive propagation. The subsidiary looks to leverage its energy-dense technology to overcome the weight issues of current battery tech holding electric plane operations back from full scaled growth. Cuberg founder and CEO Richard Wang elaborated:
The aviation industry is pursuing cleaner forms of energy and propulsion, but aircraft manufacturers are held back by the weight and immaturity of aviation-certifiable lithium-ion battery systems. With this new program, we will build certifiable battery systems enabling greatly enhanced aircraft performance and deliver a trusted end-to-end solution backed by one of the world’s preeminent battery manufacturers.
Cuberg’s battery technology is already compatible with standard manufacturing processes, promoting more seamless integration and scalability. As a result, Northvolt states that it intends to leverage Cuberg’s lithium metal cell technology with its own battery manufacturing expertise in order to deliver energy solutions to electric planes.

Packing up to 852 hp and a cutting-edge technology stack developed by Huawei, Chinese luxury brand Maextro just revealed its latest entry into the Mercedes-Maybach EQS and Rolls-Royce Spectre segment of ultra-luxe EVs. Meet the all-new Maextro S800.
Despite a somewhat steady stream of new Chinese EVs that defy expectations and threaten to re-set the global order of performance cars, semi trucks, and just about everything in between, brands like Maybach, Rolls-Royce, and even Bentley have seemed relatively “safe,” in the sense that their value is based on something a bit less objective than lap times or kW/mile.
The shimmering, sparkly, fiber-optic headliner was pioneered by Rolls-Royce over a decade ago, pushing back against the more open and accessible glass-roofs that were becoming popular in the higher end market. Huawei goes a step further, adding similar, Swarovski-like shimmer to not just the headliner – but the door handles, the headlights, projections dancing around the car as you approach it in the street.

It looks and feels special, in other words. And these cars are all about making their owners feel special. Different.
When Henry Rolls began work on his first US factory in Springfield, Massachusetts way back in 1919, there was supposedly a mantra that management repeated to the workers. It went, “every time you touch the car, you add cost. Make sure you add value.”
I’m not here to argue that Huawei is living up to the same maxim with the Maextro, but I am here to argue that this car’s bespoke, purpose-built platform doesn’t share any parts with a lesser offering from the Mercedes or BMW or Volkswagen lineup in the way that a Maybach, Rolls-Royce, or Bentley does. That may not mean much to you and me, but the people shopping six- and seven-figure cars, it might.
Those well-heeled buyers will get a choice of EREV or “pure” battery electric powertrains good for between 480 and 852 all-electric horsepower. 32 ADAS sensors including both radar and lidar compliment a suite of cameras analyze the road ahead and feed data to Huawei’s ADS road perception system, which is constantly adjusting torque distribution, suspension compression and rebound, and front and rear steering to deliver a tech-driven chauffeur experience that Huawei insists is second to none.
That digital chauffeur is also pretty handy when the weather goes sideways, too. Huawei says the Maextro’s sensor array can help it to increase the detection distance in rain, fog, and dust by 60% compared to the benchmark, while delay was reduced by 40%.
In the event a collision is unavoidable, the car can adjust its stance, seating position, raise the windows, and unlock the central control lock to enable outside help to open the doors. Following the collision, the Maextro S800 switches the redundant power supply and calls for help, as well.
Finally, reports indicate that the Maextro S800 supports the 800V high-voltage system in some trims, suitable for 6C charging, which means it can be energized with up to 390 kW of charging power, taking just 10.5 minutes to charge the 66 kWh battery in the EREV version (523 hp) from 10% to 80%.
The Maextro S800 will enter the Chinese in May this year with a price range of 1 – 1.5 million yuan (about $135–205,000 US).
Volvo Penta will debut its latest modular and scalable battery energy storage system (BESS) platform for the off-grid construction and mining industries at the bauma equipment show – here’s what you can expect.
Best-known for its marine engines and gensets, Volvo Penta is the power production arm of the Volvo Group, specializing in putting energy to work. Operating under the tagline, ‘Made to Move You’, Volvo Penta is headed to bauma 2025 with a plan to keep construction, port shipping, and mining operations moving productively and competitively throughout their transitions to battery and (in theory, at least) hydrogen power.
To that end, the company will show off a job site ready version of the scalable and modular BESS subsystem concept shown last year.
Volvo says its new, modular BESS subsystem will enable other OEMs and third party system integrators to seamlessly deploy electric power to meet the ever-exceeding energy needs in construction and mining.

“Our modular and scalable battery-electric platform is designed to support the electrification ecosystem—combining high-performance drivelines with the crucial energy storage subsystems for efficient charging and operation in construction and mining,” says Hannes Norrgren, President of Volvo Penta Industrial. “We want to meaningfully collaborate with our customers on value-added customization that will enable them to stay productive, efficient, and future-ready.”
The Penta substation at bauma will be built around the company’s “Cube” battery pack, an energy-dense solution with a favorable C-rate designed to make it easy for BESS manufacturers to offer more compact job site solutions capable of charging and discharging energy with high levels of speed and efficiency, enabling both stationary and mobile BESS configurations that can change and grow to meet the evolving needs of a given asset fleet or project.
A Volvo Penta-developed DC/DC unit converts the voltage from the Cube battery packs (600 V) into lower voltage (24 V) for powering auxiliaries and portable offices.
Electrek’s Take

Volvo Penta has always provided power. Historically that’s been from combustion, but the company is looking ahead, developing products that will bring energy to job sites, tractors, and more long after the last ICE engine shuts down.
Just days after Rivian announced that it would be making its iconic electric delivery vans available to anyone willing to pay for one, the company launched the new Rivian Upfit Program, offering a “one-stop shop” to help fleet managers put its EVs to work.
Launched in partnership with commercial vehicle heavyweights Ranger Design, Sortimo of North America, Bush Specialty Vehicles, Holman, LEGEND, and EV Sportline, the Rivian Upfit Program helps fleet buyers make the switch to electric by simplifying the ordering process and delivering an experience that more closely reflects the experience fleet managers get at dealerships.
Despite partnering with leading brands and launching into a well-establish market, however, the program’s web page seems largely aimed at people outside the space – even kicking off with an explanation of what upfitting is:
Upfitting is the process of customizing a vehicle in order to meet fleet, business, or individual consumer needs to tackle the job at hand. This work is done after the vehicle has been built and released from the factory, and can include everything from shelving modifications, flooring options, to sirens and flashers and much more.
The program was announced on LinkedIn with a number of photos indicating upfit options for Rivian’s R1T and R1S vehicles focused on lifeguard and roadside assistance duty, and Rivian’s van upfit with a HVAC/telecom style toolbox arrangement.
That same competitiveness has led to talented fleet managers at those franchise dealers putting in the effort to get to know the needs of the businesses and buyers in their regions, to understand what upfit options makes sense for their local markets, and – crucially – what to stock for quick turnaround when their customers need it.
Rivian is hoping its upfit partners will do a lot of that heavy lifting for them, but my two cents is that if building cars is hard, building relationships is harder, and Rivian isn’t going to make a good first impression by talking down to its customers. If you think differently, let me know how I got it wrong in the comments.
