How AI could change EV charging

Published

[ad_1]

New AI tools could give utilities real-time data to make the power grid and EV charging more reliable, a very small study by the University of Michigan Transportation Research Institute (UMTRI) and startup Utilidata suggests.

The researchers are using AI to analyze EV charging behavior, hoping those insights might improve the experience for drivers and help utilities prepare for the spike in electricity demand. So far, they’ve found that EV charging can draw power inconsistently and lower power quality, which can wear out charging equipment.

Those underlying problems waste energy and could lead to busted EV chargers that have become a bane for drivers. So the ability to immediately spot and even predict those issues with AI could be a game changer. AI models could give utilities a heads up on how charging might impact the power grid, the authors write. And they can also advise drivers on where and when to charge and help EV charging companies better maintain their equipment.

UMTRI initially reached out to Utilidata for this pilot study, which is meant to inform the design of a larger research project investigating the same issues. UMTRI says it’s already working with the North American Electric Reliability Council to address their initial findings.

For this study, the researchers installed electric meter adapters outfitted with Utilidata’s AI platform Karman at six EV charging stations at the University of Michigan. Karman analyzed voltage, current, power, and other dynamics between March and June of last year. The study authors also installed devices on the vehicles of 10 drivers who frequent the college campus to monitor their charging habits.

While this project is still in an early stage, researchers are hopeful it can help people prepare for the challenges that come with electrifying vehicle fleets. In the US, aging power grids are already straining to accommodate rising electricity demand from AI data centers, crypto mining, and clean energy technologies. But compared to a data center, utilities have a harder time anticipating when and where EVs will plug in to the grid.

Utilities have to cope with that unpredictability without real-time data to help them adjust. Those blind spots are becoming a bigger issue at the “grid edge,” where customers are increasingly connecting their own devices to the grid like batteries for EVs and solar panels.

“There’s a big role for AI to play at the grid edge,” says Siobhan Powell, a postdoctoral researcher at ETH Zürich who was not involved in the study. “It didn’t used to be the case, right? There wasn’t a lot interesting going on and now that we have a chance to do control, there’s more opportunity and more value in knowing what’s going on.”

One issue the researchers spotted with this study was short-cycling, inconsistent power draw from vehicles that would stop and start charging even after the battery was juiced up fully. Not only does that burn through energy inefficiently, but it can also overheat wires and transformers. They also found that EV charging lowers power quality, when electricity deviates from ideal voltage and frequency ranges. Flickering is a telltale sign of low power quality, which can also cause more wear and tear on equipment.

“The biggest takeaway, I think, is that we confirmed that there’s a lot of behaviors from electric vehicles that are not known to anyone — not known to car owners, not known to grid operators, not known to charger OEMs,” Utilidata’s vice president of product solutions, Yingchen Zhang, says. “So there’s a great need to really open up all this data.”

The study authors cautiously make the case that places with a lot of unmanaged EV charging could see larger impacts on the power grid. In a worst-case scenario, they say that could impact power supply to other customers. But Zhang is quick to say that the chance of a power outage as a result is very low.

“It’s good to know exactly how these new charges affect voltage, power quality issues locally, but I wouldn’t jump to outages,” Powell says, because there are a lot of steps utilities can take to prevent outages. And again, this is a very small study about unpredictable charging behavior, so it’s still too early to make sweeping statements about broader grid impacts from these early findings.

Both Powell and Zhang want to avoid causing undue alarm over the impact EV charging can have on the grid — particularly as EV adoption faces partisan attacks. “A lot of the fears are because people don’t know the actual EV behavior,” Zhang says. “So actually revealing this information will diminish a lot of those fears.”

The rise of AI has also raised concerns about increasingly energy-hungry data centers stressing the grid. Zhang says his company is thinking about that, too, using custom-designed chips from Nvidia to consume less energy than more generic AI chips. And using machine learning in this way to analyze data is generally much less energy-intensive than generative AI models that spit out text and images.

It comes down to preparation as the key to shoring up the power grid against new technologies that change the way we live, work, and get around. Fleets of EV batteries could even help bolster the grid by acting as virtual power plants that feed power into the grid when it’s needed. Automakers are already testing this out, in part to make EVs more affordable for customers. “We need EVs. We need this transition to happen. And there are things that we have to do to prepare the grid, but we can do them,” Powell says.

Starlink Mini brings space internet to backpackers

Published

[ad_1]

SpaceX’s Starlink internet-from-space service is already available for boatsplanes, vanlifersAmazonian villages, and rural homes in over 75 countries — now it’s coming to backpackers.

The new compact DC-powered Starlink Mini is about the size of a thick laptop and integrates the Wi-Fi router right inside the dish. And despite using less power than other Starlink terminals, it can still deliver speeds over 100Mbps.

“This product will change the world,” claimed SpaceX CEO Elon Musk on X, saying it took less than five minutes to setup.

Notably, the Mini kit consumes an average of just 20-40W compared to the 33-62W we measured just two years ago with a Standard Actuated dish and separate AC-powered Wi-Fi router. That means you can power the Mini dish for two to three hours from something like an Anker Prime 27,650mAh (99.54Wh) power bank, or a little over an hour with smaller 10,000mAh (40Wh) portable batteries you probably already have laying about. It requires a USB-C PD power source with a minimum rating of 100W (20V/5A). 

The Mini dish measures 11.75 x 10.2 x 1.45 inches (298.5 x 259 x 38.5mm) and weighs just 2.43 pounds (1.1kg), or 3.37 pounds (1.53kg) with the 49.2 foot (15m) DC power cable and kickstand. It has an IP67 rating meaning it’s protected from dust and rain, including short periods of water immersion.

In the US, Starlink Mini is an add-on to Residential plans — at least for now. The Mini kit costs $599 which is $100 more than the standard dish, and will cost an extra $30 per month to add the Mini Roam service to existing $120 Residential plans. That gives Starlink Mini users up to 50GB of mobile data each month, with the option to purchase more for $1 per GB, according to early-access invitations sent to some exiting US Starlink customers. 

While Starlink Mini is new to the US, a Starlink support page says it’s already available in Colombia, El Salvador, Guatemala, and Panama where it can be purchased with Mini Service or Mobile – Regional Service plans. In those countries, there’s no data or speed caps to use Mini, and in-motion and ocean use is not allowed. SpaceX says it’ll expand to more markets over time.

“Our goal is to reduce the price of Starlink, especially for those around the world where connectivity has been unaffordable or completely unavailable,” reads the Starlink support page. “In regions with high usage, like the US, where Starlink Mini places additional demand on the satellite network, we are offering a limited number of the Starlink Mini Kits to start at a higher price point.”

As a standalone service, Starlink Mini could be transformative for anyone in need of an inexpensive and sharable internet service that efficiently sips DC battery power. This includes families that depend upon a cobbled together solar generator for power, a squad of soldiers trying to fight back an invasion, or just bikepackers and overlanders taking the road less traveled.

Elon Musk has another secret child with exec at his brain implant company

Elon Musk, who has long touted claims about the world’s supposed depopulation crisis, had another child with an executive at his brain implant company Neuralink, according to a report from Bloomberg. Neuralink director Shivon Zilis reportedly had the child with Musk earlier this year.

As noted by Bloomberg, Musk has repeated that line several times in the past, including during a 2022 interview with Tucker Carlson and again during an interview at the Milken Institute conference in May. He told Carlson “a collapsing birth rate is the biggest danger civilization faces, by far.” In 2021, Musk’s nonprofit organization donated $10 million to the University of Austin to fund the Population Wellbeing Initiative, a research group that studies the human population.

The revelation also follows multiple reports alleging inappropriate conduct from Musk in the workplace and with subordinates. A recent report from The Wall Street Journal said Musk had a sexual relationship with a former SpaceX intern who later became one of the company’s executives. Another employee says she refused Musk’s requests to have children with him several times, according to the Journal.

Youth plaintiffs in Hawaii reach historic climate deal

Published

A group of young plaintiffs reached a historic climate settlement with the state of Hawaii and Hawaii Department of Transportation in a deal that will push the state to clean up tailpipe pollution.

The 13 youth plaintiffs filed suit in 2022 when they were all between the ages of 9 and 18. In the suit, Navahine F. v. Hawaii Department of Transportation (HDOT), they alleged that the state and HDOT had violated their right to “a clean and healthful environment,” which is enshrined in Hawaii’s constitution.

“We got what we came for, and we got it faster than we expected.”

The settlement, reached on Thursday, affirms that right and commits the DOT to creating a plan to reach zero greenhouse gas emissions from transportation by 2045. To hit that goal, the state will have to dedicate at least $40 million to building out its EV charging network by the end of the decade and complete new pedestrian, bicycle, and transit networks over the next five years. The settlement also creates a new unit within HDOT tasked with coordinating CO2 emission reductions and a volunteer youth council to advise HDOT.

“I am so proud of all the hard work to get us to this historic moment. We got what we came for, and we got it faster than we expected,” the lead plaintiff, Navahine F., said in an emailed statement.

Back in 2018, Hawaii committed to reaching net-zero carbon dioxide emissions by 2045 — in line with what climate research determined was necessary to meet the Paris climate accord goal of stopping global warming. But the state wasn’t doing enough to reach that goal, the plaintiffs alleged. Transportation makes up the biggest chunk of the state’s greenhouse gas pollution.

“Climate change is indisputable,” Ed Sniffen, HDOT director of transportation, said in a press release. “Burying our heads in the sand and making it the next generation’s problem is not pono.”

Youth in Montana scored another historic legal win last year after the first climate case of its kind to go to trial. A state court found that a Montana policy that barred officials from considering the consequences of climate change when permitting new energy projects violated the rights of the plaintiffs to a “clean and healthful environment.” The lawsuit in Hawaii was expected to be the next landmark youth climate case to go to trial in the US. Several other state and federal youth climate suits are still pending in the US.
