One of the less obvious features of the Tesla Cybertruck is its vehicle voltage architecture. The Cybertruck is the first EV from the automaker to use a 48-Volt (48V) electrical system implementation throughout the entire vehicle, as compared to the 12V systems that are used in pretty much every other vehicle on the planet. Today, Tesla shared its 48V implementation documentation with other major automakers — including competitors like Ford.

Ford’s own CEO Jim Farley confirmed the news on X, formerly Twitter, last night.

Ford CEO Jim Farley confirms Tesla has shared its 48V architecture documentation

Tesla CEO Elon Musk also chimed in.

The consequences of Tesla’s actions won’t be immediately obvious in any other carmaker’s products, as they will likely take a long time to manifest into any real changes for the industry — if they do at all. But let’s take a step back.

Why does 48V architecture matter?

48V architecture is a huge deal not because it enables any particular feature or capability for any one car, but because it will lead to a step change in how automakers wire, accessorize, and electrically engineer their vehicles.

The first mass-produced vehicles generally used 6V architecture to power things like headlamps, and the industry broadly began to adopt 12V electrics in the 1950s. By the late 1960s, almost every car on sale in the US used 12V electrics — power windows, interior lighting, cigarette lighters, brake lights, ignition spark, batteries, and more all unified around this common voltage standard. This change was a big deal, because it meant that the suppliers who built a lot of these electrically-driven components could easily adapt their products to work with any car. Parts became yet more standardized (plus, more affordable and reliable), and eventually 12V became the universal standard for vehicle electrics.

The problems with 12V architecture, though, have been looming (pun intended) for years. Because of the low voltage of this architecture, delivering sufficient power to all vehicle systems that need electricity became more and more complex. And as cars integrated more and more electrical components over the years, this led to ruinously complicated vehicle wiring layouts. (I want to be clear: I am vastly oversimplifying the nature of the challenges of 12V architecture, and it should be obvious by now I’m not an electrical engineer. I probably shouldn’t be allowed to be too close to a wall outlet, frankly.)

Switching to 48V architecture alleviates a huge number of challenges automakers are facing with 12V. The biggest one, though, is complexity: You need far less complex wiring harnesses to power all your vehicle systems, because each wire can supply far more power and voltage in a 48V system. 48V architecture also potentially improves overall electrical efficiency for reasons that I am not sufficiently qualified to explain beyond a kindergarten level, meaning your car’s accessory systems may require less power overall to operate (quite important for an EV).

12V roadblocks remain despite Tesla’s action

The challenge in adopting 48V architecture primarily lays in the vehicle supplier ecosystem, but that conclusion requires a bit of context setting.

If you cannot convert all of a vehicle’s systems to 48V architecture, the benefits of using such an architecture start to diminish pretty quickly in the form of introducing new complexities (i.e., a hybrid 48V / 12V vehicle architecture). As such, most automakers have clung to 12V because they know it and it works.

If an automaker decides to move to a 48V architecture, whatever car it builds must use 48V-ready accessories. But, suppliers aren’t incentivized to build such accessories without sufficient demand. While carmakers like Ford certainly have the power and scale to commission 48V parts independently, the per-unit cost of those components is likely to be substantially higher than their 12V equivalents — especially if they’re being produced in comparatively low volumes. And, many carmakers would be forced to make such a transition slowly over their entire vehicle lineup (it’s worth noting that ICE vehicles can use and would benefit greatly from 48V systems, too). And so, most carmakers stick with 12V. It’s a chicken-and-egg kind of issue.

Why did Tesla share its 48V architecture?

To be frank, Tesla isn’t sharing its 48V architecture from the Cybertruck for purely altruistic reasons. Once you understand the conundrum around vehicle suppliers in the 12V world and making a transition to 48V, things start to come into greater focus. Tesla knows that transitioning to 48V is going to be incredibly difficult for legacy OEMs, and while there is potentially upside for Tesla in such a change (more on that in a moment), this is something of a PR move.

By publishing its 48V architecture, Tesla is saying “OK, we’ll show you how we did this thing — a thing you say is really complicated and difficult and would take years to replicate. You can just copy us.” But Tesla knows full well that even a powerful and well-resourced company like Ford can’t spin up a 48V accessory supply chain overnight, and that such a change would incur very substantial non-recurring engineering work (NRE, as it’s known in some industries).

For Tesla, though, there are theoretical benefits in the event the wider industry switches to 48V vehicle systems. The biggest one is the supply chain. The more components in the global vehicle supply chain that are designed for 48V vehicle systems, the lower the cost of those components will become over time — through volume, competitive engineering, and increased reliability. The second is a bit more nebulous, but arguably just as important: Engineers and other skilled workers in the industry will coalesce their work and knowledge around 48V systems, reducing the amount of redundant work happening and increasing the number of workers in the hiring pool who can understand and innovate on Tesla’s systems (and who can bring their knowledge to Tesla, barring any intellectual property infringement, of course).

Electrek’s Take

It’s hard to see a downside to this move for anyone — for Tesla, the industry, or for the engineers designing the vehicle systems themselves. And it’s plain that the supplier ecosystem needs a kick in the pants to accelerate the transition to 48V, and that the benefits of such a transition are very substantial.

But it’s much harder to say how much of an impact Tesla’s decision to share its 48V design will actually have. Clearly, automakers are already incentivized to move to 48V, but doing so is challenging for a reason — it’s not just laziness. There are legitimate (if frustratingly financial and logistical) reasons that the 48V transition is moving along slowly.

It’s very possible that providing publicity around this relatively esoteric technical issue will be the greatest factor in instigating more aggressive work to implement 48V vehicle systems, as opposed to any technical know-how gleaned from Tesla’s documentation.

It should also be noted that Tesla has two distinct advantages in transitioning to 48V that legacy automakers do not. The first is being unusually vertically integrated in its approach to building vehicles — Tesla designs almost all of its own vehicle systems, even if they may be procured from third parties who actually manufacture them. The second is that Tesla doesn’t have many legacy vehicle designs to support or consider in deciding to transition electrical architectures. Put another way, Tesla’s focus on independent engineering and low legacy debt are huge reasons it can introduce a 48V vehicle while other auto OEMs continue to stick to 12V and likely will for years from now, even in their EVs. And simply telling other carmakers how it built a 48V system won’t change those realities overnight.

This 3GW Gobi Desert solar farm can power 2 million households

Gobi Desert solar farm

China just connected its largest single-capacity solar farm built on a former coal mining area, which is in the Gobi Desert, to the grid.

The Mengxi Blue Ocean Photovoltaic Power Station, located in Otog Front Banner, Ordos, Inner Mongolia, came online on November 5. With a massive installed capacity of 3 gigawatts (GW) and over 5.9 million solar panels, the plant will generate around 5.7 billion kilowatt-hours of electricity annually – enough to power 2 million households.

This huge project will save about 1.71 million tons of standard coal each year and cut carbon dioxide emissions by roughly 4.7 million tons, which is equivalent to planting 62,700 hectares (around 155,000 acres) of trees.

Built on coal mining subsidence land, Mengxi Blue Ocean is part of China’s national West-East Electricity Transfer Project, which brings investment and development to western China west while supplying the growing need for electricity in the eastern provinces.

The solar farm includes the country’s first large-scale outdoor solar testing base in the Gobi Desert climate, demonstrating the potential for large solar installations in challenging environments.

The power station makes use of new rare earth alloy grounding materials, cutting costs by 40%. It also replaces traditional concrete foundations with steel to minimize impact on the local grassland ecosystem.

Chuang Xihong, deputy director of the Engineering Construction Department of Guodian Power Group, CHN Energy’s parent company, explained that Mengxi Blue Ocean is an agrivoltaic project as well [via PV Tech]:

Fine forage and sand-fixing plants are planted under the PV modules, providing grazing for Australian White Sheep and chickens. A composite ecological development model will be established where PV power generation and breeding will go hand in hand.

Save exclusive ,568 on EcoFlow DELTA Pro Ultra, Velotric Black Friday e-bike additions, Anker SOLIX + Heybike flash sales, more

It should be no surprise that we’re closing out the week with another great lineup of Black Friday Green Deals. Leading the official sales is the exclusive discount our readers are getting on the EcoFlow DELTA Pro Ultra Home-Backup Station at a new $4,230 low. Coming up right behind it we have Velotric’s early Black Friday changeup that is adding two more e-bikes to the savings event while also offering an “add three, get 30% off” promotion for accessories – all starting at $1,099. We’ve also got two weekend flash sales, the first being several Anker SOLIX solar generator and home-backup bundles at new low prices and starting from $1,399. The other is a second chance at Heybike’s Ranger S Folding e-bike for $999, as well as some price reductions. Plus, all the other hangover Green Deals are in the links at the bottom of the page, like yesterday’s long-awaited Rad Power Black Friday sale that has increased savings up to $700 on new and old e-bikes alike, and more.

Head below for other New Green Deals we’ve found today and, of course, Electrek’s best EV buying and leasing deals. Also, check out the new Electrek Tesla Shop for the best deals on Tesla accessories.

Save a 9to5Toys-exclusive $1,568 on EcoFlow’s DELTA Pro Ultra whole-home backup station at new $4,230 low

Wellbots is giving 9to5Toys readers an exclusive chance at savings on EcoFlow’s DELTA Pro Ultra Whole-Home Backup Station for $4,230.59 shipped, after using the promo code 9TO5DPU9 at checkout for an additional 9% off. Normally priced at $5,799 here, with a higher $6,098 MSRP direct from EcoFlow, this unit has never seen discounts this large, with the brand’s current Black Friday sale offering what we considered the best price of the year at $4,649, until today. Taking advantage of this exclusive offer gives you a total of $1,568 off its going rate at Wellbots ($1,867 under its original MSRP) and lands it at the best price we have tracked to date.

EcoFlow’s DELTA Pro Ultra is the hands-down best option from the brand for backup power of your entire home, providing a starting 6.1kWh LiFePO4 battery capacity and 7,200W power output that can be invested in and further expanded up to a massive 90kWh capacity and 21.6kW output. For context, the station alone can keep your essentials running for two days on one full battery and up to 15 days with its fully expanded capabilities – and that’s not even factoring in any solar panel setup you have for it that recharges and replenishes its battery. Aside from just supporting you through blackouts with the auto-switchover, it will analyze your regular power usage to offset peak rates while utilizing solar charging to help lower your energy costs (requires Smart Home Panel 2, sold separately).

There are multiple ways to recharge the Ecoflow DELTA Pro Ultra’s battery outside the expandable 5.6kW to 16.8kW solar input, with a wall outlet able to recharge the battery in just two hours, with other options including EV piles and generators too. As an example, in terms of its solar charging capabilities, if you were to invest in a fully stocked and expanded system (three Ultra Pro stations + expansion batteries), a single hour of solar charging would give you the power needed to run your home for the entire day. It can handle severe temperatures of -4 degrees to 113 degrees and even comes with an IP54 dust-proof and splash-proof rating.

Velotric Go 1 Utility e-bike

Velotric adds two e-bikes to early Black Friday + 30% discounts on three accessories – deals start from $1,099

Velotric is switching its early Black Friday sale into its second gear through November 28, including two more e-bikes to the sales lineup and offering an “add three save 30%” promo on accessories. Aside from those we already saw at the start of the month, the brand includes the Go 1 Utility e-bike for $1,299 shipped and the Packer 1 Cargo e-bike for $1,599 shipped. Normally these models go for $1,699 and $2,199, respectively, we’ve seen most sales drop costs down to $1,399 and $1,699 for most of 2024, though there was one August flash sale that lowered the prices by $50 more and we have also seen the Go 1 Utility e-bike as low as $1,099 in past years back in the pre-tariff marketplace. Still, you’re looking at some of the lowest prices tracked, giving you some solid affordability on reliable e-mobility solutions.

Velotric’s Go 1 Utility e-bike cruises into view at a 20 MPH top speed that you can unlock up to 25 MPH, with the 500W hub motor peaking at 900W and powered by the removable 692Wh battery, which also provides a solid 55 miles of travel on one full charge. There are five pedal assistance models here, and a bunch of great features for the price – especially the inclusion of Apple Find My alongside the usual smartphone app integration. You’ll also enjoy stocked puncture-resistant tires, a removable thumb throttle, a 7-speed Shimano derailleur, an integrated LED headlight, a rear rack that has an integrated taillight with brake lighting, and a 3.5-inch LCD display with a USB port.

With the Packer 1 Cargo e-bike, you’ll be able to haul up to 176 pounds of packages, passengers, both, and more at top speeds of 20 MPH (which also unlocks to 25 MPH) for up to 52 pedal-assisted miles thanks to the pairing of its 750W rear-geared hub motor (peaks at 1,200W) and the removable 692Wh battery. Using just the throttle for pure electric action can surprisingly net you up to 45 miles of travel. Among its features you’ll find Apple Find My and smartphone app integrations, 4-piston hydraulic disc brakes, a hydraulic suspension fork, an 8-speed Shimano derailleur, fenders over its 26-inch front/20-inch rear tires, an LED headlight, a taillight with braking functionality, and an LED display.
