A young battery startup in China claims its latest cell technology is able to alleviate a major issue for EV owners today – the loss of charging performance and range in inclement weather, especially cold climates during winter. By utilizing superconducting materials, Greater Bay Technology says its new cells can charge and function as normal within six minutes, no matter the temperature outside.

Guangzhou Juwan Technology Research Co., Ltd. – better known as Greater Bay Technology is a battery startup spun out of GAC Motor as recently as 2020. In that short time, the company has already delivered what it calls an eXtreme Fast Charging (XFC) cell that can fully charge in 15 minutes.

GAC Aion has already implemented this technology into its EVs in China, beginning with its V Plus SUV. Its early success has helped the young startup become a unicorn or sorts, gathering over RMB 1 billion (~$155M) in Series A funding.

Not to be outdone, the Greater Bay is now touting a new cell it calls the Phoenix EV battery – promising a range of 1,000 km (621 mi) on a single charge and a level of performance fidelity that is unaffected by the temperature outside, even in winter.

GBT’s new EV battery can fast charge in winter or summer

The startup recently shared impressive details of its new Phoenix battery cells in a video on its WeChat page, which can rapidly heat from -20℃ (-4℉) to 25℃ (77℉) in just five minutes.

This advanced thermal management helps stabilize the EV battery no matter if it’s the peak of summer, or the dead of winter, providing rates from 10-80% SOC in just six minutes (8C) on platforms ranging from 300V to 1,000V. Per the video:

Based on essence of battery heat exchange, GBT’s Phoenix battery takes full advantage of its original lightweight and ultra high-thermal conductivity low-dimensional materials, making best use of the cell’s heat exchange area, building up a 3-D thermal management system. Its heat exchange is increased by 18 times traditional solutions, realizes extreme fast cooling and heating, with a temperature control rate raised by three times.

Additionally, the EV battery cells combine for what Greater Bay calls a “magazine clip” style structure that not only enables the optimized heat exchange, but better protects against damage from collisions or cell penetrations.

Like many of these breakthroughs we often see, the Phoenix EV batteries have not reached mass production, but could be here by next winter. Greater Bay Technology states the Phoenix cells will be implemented in GAC Aion EVs next year, and it is currently in talks with other automakers as well.

Electrek’s Take

I don’t want to get my hopes up just yet for two reasons. For one, these battery breakthroughs appear to happening more and more often, and rarely involve the words “mass production” or “cost parity.”

To counter my own insecurities, Greater Bay has been innovating quite quickly and already has fast charging cells in EVs overseas. Remember, it’s only been in business for three years. Not to mention it’s financially backed by one of the largest automotive conglomerates in China.

Which brings me to my next question: When (if at all) will we see this tech implemented outside of China? If Greater Bay can in fact deliver an EV battery that charges the same rate as other cells in freezing winter weather, it could significantly expedite a global rate of EV adoption that is already snowballing.

I know my family and friends in the Midwest would be much more inclined to go all-electric knowing they won’t risk losing any range during the winter months. Still feels like a pipe dream at this point, but if it can scale, it could be a game changer for the entire industry.

GM's interesting electric motorcycle patent fuels two-wheeler speculation

General Motors may be better known for its lineup of full-size trucks and SUVs, but a recently published patent shows the legacy automaker has at least considered something much smaller and nimbler: an electric motorcycle.

The patent, which surfaced earlier this year in a report by Visordown, outlines a lightweight, scrambler-style electric two-wheeler that has set off a fresh wave of speculation about GM’s potential interest in electric motorcycles or micromobility.

The design in the patent filing shows a slim electric motorcycle with a flat bench seat, upright handlebars, and dual-sport tires, suggesting a utility-forward ride meant for light off-road or potentially even mixed urban use (if it were homologated for street use).

The rear hub motor and what appears to be a central battery housing point to a simple, low-maintenance drivetrain, potentially aimed at the commuter or recreational rider market.

The overall look is somewhere between a moped and a small electric dirt bike, reminiscent of models like the Sur Ron Light Bee or Talaria Sting, though slightly more street-looking with less of a focus on pure dirt.

While the patent doesn’t include performance specs or firm production plans, it’s the clearest signal yet that GM is at least experimenting with the idea of higher-powered two-wheeled EVs. And there is some precedent. GM previously dipped a toe into the micromobility waters with the Ariv electric bicycle project, and more recently partnered with Recon Power Bikes to release a Hummer-branded fat tire e-bike.

Both efforts showed that GM sees value in offering electric alternatives beyond the traditional four-wheel format, even if the Ariv program quietly ended after a short run.

Whether this patent leads to a full-fledged GM electric motorcycle remains to be seen. It’s entirely possible the design is a concept or technology demo with no intention of hitting the market. But there are other possibilities too. GM could develop a motorcycle under one of its existing sub-brands, create a new division specifically for electric powersports, or partner with an existing two-wheeler manufacturer to license or co-develop the platform.

The timing wouldn’t be far-fetched. Despite bumpy roads in the larger flagship electric motorcycle market, lightweight electric motorcycles are booming, with companies like Ryvid targeting urban riders looking for clean, compact alternatives to traditional gasoline-powered bikes.

At the same time, a growing number of younger consumers are bypassing car ownership entirely, instead looking toward e-bikes, scooters, and low-speed electric motorcycles for daily transport. A small, stylish, and affordable GM electric motorcycle could hit that sweet spot.

Of course, turning a patent drawing into a real-world vehicle is a big leap, and GM’s own e-bike history is a reminder that two-wheeled projects can be short-lived. Still, it’s hard to ignore the symbolism of this move: even one of America’s largest automakers is exploring what personal electric transportation looks like when you cut the vehicle in half. GM might not be ready to ditch its trucks, but it clearly hasn’t ruled out hopping on a bike.

Current Classics: Rolls-Royce Phantom V gets even smoother and quieter

The electric restomod experts at Lunaz have turned their talents towards the classic Rolls-Royce Phantom V limousine – and the result is exactly the kind of smooth, quiet, and luxurious ride RR’s founders would have built.

Rolls-Royce’ founders dedicated their engineering talents to developing cars that were smooth, quiet, and adequately powerful – and they spared no expense. The company Charles Rolls and Henry Royce founded would eventually go on to develop some of the most powerful and celebrated combustion engines of the twentieth century … but the car they wanted to build? It was electric.

“The electric car is perfectly noiseless and clean,” Charles Rolls told The Motor-Car Journal, all the way back in April of 1900. (!) “There is no smell or vibration, and they should become very useful when fixed charging stations can be arranged. But for now, I do not anticipate that they will be very serviceable – at least for many years to come.”

Well, 125 years seems like “many” to – and the talented craftspeople and engineers at Lunaz seem to agree. Meet the Lunaz Rolls-Royce Phantom V limousine.

Lunaz says it’s true to Rolls’ vision “down to the smallest, most indulgent detail.” To that end, the company re-trims the modern heated and ventilated seats in fine leathers, hand-cut and stitched to the buyers’ specifications. In the rear, the center console can be ordered with a built-in cigar humidor, a cocktail bar, or some other custom-spec, lockable storage lined in suede and polished walnut (translation: guns and drugs, probably).

When reimagining the Rolls-Royce Phantom V, (we) started by understanding the essence of its original design. Every component and dynamic was scrutinized to identify where thoughtful innovation could truly elevate the experience. The result is a harmonious blend of modern advancements and original mastery, unlocking new levels of performance, reliability and refinement while honoring Rolls-Royce’ classic soul.

LUNAZ

Like the classic Bentley S2 Continental the company revealed in 2023, the big electric Roller is equipped with an 80 kWh battery pack sending electrons to a proprietary Lunaz drivetrain featuring 400 hp worth of electric motors delivering a silky-smooth 530 lb-ft of torque, good for a 0-100 km/h (62 mph) swoosh in about seven seconds. Of course, why you’d ever ask your driver to perform such plebian stunts is simply beyond me.

The transformation and restoration took more than 5,500 man-hours to complete, and involve more than 11,000 new or reconditioned components at a cost of more than £1 million (about $1.35 million US). If you place your order today, you should get yours in 18-24 months.

Fortescue Infinity Train electric locomotive never needs fuel or charging

Fortescue has taken the wraps off a prototype of its proposed “Infinity Train” electric locomotive, making the 1,100 km (about 685 miles) trip from Perth to the Pilbara and marking a major milestone in the decarbonization of the company’s heavy haul operations.

Co-developed with the locomotive experts at Downer Group, Fortescue revealed its concept for a battery electric “Infinity Train” back in March of 2022. At the time, the company promised a “world’s first” iron ore train capable of fully charging its batteries through regenerative braking. The two companies claimed the clever technology would create a self-sustaining, zero-emission rail system powered entirely by the force of gravity during the train’s loaded downhill travels.

This week, the concept went from the drawing board to the real world, completing an 1,100 km trip across Australia and proving itself to be up to the task of handling the grueling demands of Fortescue’s massive mining operations.

“We’re thrilled to see our battery electric locomotive prototype arrive in the Pilbara,” said Ellie Coates, CEO of Fortescue Zero. She added that the achievement, using zero fossil fuels, “represent(s) a major step in Fortescue’s journey to Real Zero.”

The Fortescue Infinity Train uses the energy produced by slowing the loaded train on downhill sections of the company’s 385 mile private, heavy-haul rail network to recharge its battery systems. That energy is enough to bring the unloaded train back to the mine, eliminating the need for external charging infrastructure or additional renewable energy sources, making the train almost entirely self-sufficient.

Fortescue says the deployment of the Infinity Train concept at its mines will eliminate more than 82 million liters of diesel fuel consumption (about 21 million gallons, which ChatGPT tells me amounts to about 235,200 tons of CO₂ emissions).

That change alone would eliminate about 11% of Scope 1 emissions annually for Fortescue all on its own, putting it well on its way to its stated goal of achieving “Real Zero” emissions-free operations.

Electrek’s Take

Using gravity to charge up heavily-laden mining vehicles on downhill runs is an idea that’s been put into practice for years, with great success wherever the topography allows (since 2017, at least). Combining that clever use of gravity, traction braking, and battery storage for use on a rail system like this just seems smart, and it makes me think we’re just scratching the surface of all the clever ways electrification and battery storage will eventually get put to use.

I wonder what would happen if you threw some battery electric rail cars into the mix, as well!? You guys are smart, head down to the comments and let me know (and, while you’re there, help me check ChatGPT’s math on those carbon emissions).
