Smart charging may be key to saving power grid in world of EVs
As electric vehicle (EV) sales rise, the big question for power grid operators, charging companies and governments is how to run tens of millions of vehicles without crashing local networks or spending billions on grid upgrades.
The answer: smart charging.
Simply put, smart charging software allows EV owners to plug in during expensive peak hours, without the vehicle drawing power until cheap off-peak hours. This eases strain on the electric grid, makes better use of renewable energy and saves drivers money.
Without it, millions of EV owners plugging in after work – auditing firm EY estimates Europe will have 65 million EVs by 2030 and 130 million by 2035 – could overload local grids, causing blackouts.
“The shift to electric will be nigh on impossible without smart charging,” Chris Pateman-Jones, CEO of British EV charger company Connected Kerb, told Reuters while demonstrating a pilot project on public chargers in Hackney, a London borough.
Using Connected Kerb’s smartphone app you can set your charging speed, charge time and exact price down to a low, slow “Eco” rate of 19 pence (26 U.S. cents) per kilowatt.
“It’s so much cheaper and simpler,” said Ged O’Sullivan, a 65-year-old pub owner who cut his plug-in hybrid’s charging bill by 30% with Connected Kerb.
Smart charging for public chargers is a significant challenge because so few are available for people who cannot charge at home because they park on the street.
According to a report from EY and Eurelectric, Europe alone will need 9 million public chargers by 2035, up from 374,000 today.
The near future should also bring “bidirectional” or “vehicle-to-grid” charging, where millions of EV owners could sell their EV batteries’ juice back to grid operators during peak hours.
Even in Britain where smart charging at home is widely available, many EV owners are unaware it exists, according to Britain’s energy regulator, Ofgem. In the United States, only a tiny fraction of utilities offer it, according to utilities group the Smart Electric Power Alliance.
And few cars today beside Renault and Hyundai’s upcoming Ioniq model are capable of bidirectional charging – though more are coming.
“Most cars, at this point, do not support this bidirectional charging yet,” said Robin Berg, CEO of We Drive Solar, which has supplied hundreds of bidirectional chargers for a pilot project in the central Dutch city of Utrecht and worked with Renault SA (RENA.PA) and Hyundai Motor Co (005380.KS) on their vehicles. “Other carmakers will follow.”
Nearly 20% of new cars sold in the Netherlands and almost 12% in Britain in 2021 were fully electric.
State support has put Norway at the forefront of electrification, where EVs made up almost three-quarters of sales in the capital Oslo. Some local substations were built in the 1950s and without smart charging Oslo would need massive, costly grid upgrades.
“To handle this we need smart charging solutions because we don’t want to over-invest in the grid,” said Sture Portvik, who heads Oslo’s charging infrastructure efforts.
‘AWARENESS IS LOW’
Connected Kerb aims to have 190,000 UK on-street chargers by 2030, enabling it to predict consumer charging patterns for grid operators and offer lower rates when the available renewable energy is abundant, said Pateman-Jones.
“Today when there’s too much wind on the grid, wind farms are told to turn the wind turbines off,” he said. “With smart charging we can pull more of that power.”
Some UK energy providers already offer low off-peak rates for home smart charging, but few EV owners use them.
“The perception is smart charging at home is a done deal,” said Charlie Cook, CEO of Rightcharge, a UK firm that helps EV owners find low tariffs. “But the reality is awareness of these tariffs is surprisingly low.”
Rightcharge estimates smart charging could save UK drivers 10 billion pounds ($13.5 billion) by 2030.
British car dealer network Lookers (LOOK.L) guides EV buyers to Rightcharge’s website to check their options.
Lookers’ business development director, Andrew Hall, said “early adopter” EV buyers are “pretty savvy about smart charging.”
“But that is changing as EV sales rise,” he added.
Utilities group the Smart Electric Power Alliance estimates only 50 out of 3,000 U.S. utilities offer smart charging.
EV charging company ChargePoint’s (CHPT.N) U.S. chargers can all smart-charge, but it wants more utilities to offer it.
“We see a lot of positive response from customers when their utility is offering those rates,” said Anthony Harrison, ChargePoint’s North American head of utility partnerships.
Charging provider Blink Charging Co (BLNK.O) has one set rate until smart charging is widely available.
“We decided to keep it simple for our customers,” said Blink CEO Michael Farkas.
‘HORRENDOUSLY EXPENSIVE’
Bidirectional charging may be crucial.
“The whole idea behind bidirectional charging is to balance the grid,” said We Drive Solar’s Berg, who estimates a fully charged EV can power the average home in the Netherlands for a week.
Serge Colle, EY’s global energy resources leader, said smart and bidirectional charging are better than “horrendously expensive” power grid upgrades.
“We can’t possibly open up streets quickly enough to add more copper and do the necessary reinforcement,” Colle said.
Regulator Ofgem estimates that peak power reductions from smart and bidirectional charging by 2050 could match “10 Hinkley Point C Nuclear Plants” – a two-reactor plant under construction in England.
The U.S. market has more than 10 vehicle-to-grid pilot projects using school buses under way.
California-based vehicle-to-grid company Nuvve Holding Corp (NVVE.O) has formed Levo, a joint venture with private equity firm Stonepeak – which chipped in $750 million – to enable EV fleet owners to sell power to utilities.
“Because our customers are able to generate revenue we’re able to reduce the total cost of ownership for those vehicles, at times completely cost-neutral,” said Nuvve CEO Gregory Poilasne.
Charger makers like Brisbane, Australia-based Tritium Dcfc Ltd (DCFC.O) are also developing bidirectional chargers.
CEO Jane Hunter said Tritium will launch a bidirectional, fast-charging wall unit in 2023 for fleets and homeowners.
More automakers are embracing bidirectional charging. Ford Motor Co (F.N) has partnered with solar power company Sunrun Inc (RUN.O) to use its F-150 Lightning pickup truck to power homes.
But Oslo has invested extra money in pilot projects for bidirectional chargers because it believes in the concept. So far, however, it has been disappointed that more carmakers have not yet introduced vehicles that can feed power back into the grid.
“The limitations for bidirectional charging has been the car producers,” infrastructure chief Portvik said. “The big carmakers have to step up.”

Swirling, vortex-like patterns observed on the sun’s surface
The researchers said the observations may provide insight into underlying physical processes that impact the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on Earth.
Astronomers have obtained the highest-resolution images to date of our sun’s visible surface, observing swirling, vortex-like patterns in superheated solar gases reminiscent of the shapes depicted in the nocturnal sky in Vincent van Gogh’s 1889 painting “The Starry Night.”
The researchers made the observations of a portion of the sun’s photosphere, a relatively thin layer — about 60 miles (100 km) in depth compared to the overall solar diameter of roughly 865,000 miles (1.4 million km) — using the U.S. National Science Foundation’s Hawaii-based Daniel K. Inouye Solar Telescope, Reuters reported.
The still images and time-lapse video reveal continuously growing whirls of hot plasma, gas heated to temperatures so high that subatomic particles called electrons break free from atoms and form a broth of charged particles. The observed whirls are large on a human scale but small on the scale of a stellar surface, with diameters ranging from about 12 miles (19 km) — the minimum scale detectable by the world’s most powerful solar telescope — up to roughly 100 miles (170 km).
The researchers said the observations may provide insight into underlying physical processes that impact the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on Earth.
The curly, circular patterns do not represent random shapes, but rather are the first detection of a phenomenon called Kelvin-Helmholtz instability, or KHI, on the surface of a star. KHI, first described in the 19th century, refers to a dynamic process that happens when two parallel streams of fluids or gases interact while moving at different velocities.
“The interface can become unstable and develop wave-like vortices that grow in size until they break apart, not unlike waves out on a lake or out on the ocean in windy conditions,” said astronomer Friedrich Wöger, a senior scientist at the National Science Foundation’s National Solar Observatory in Colorado, the Inouye telescope’s instrument program scientist, and co-lead author of the study published on Wednesday in the journal Nature.
Swirling clouds caused by KHI are a well-known, albeit rare, meteorological occurrence on Earth, and also have been observed in the atmospheres of the giant gas planets Jupiter and Saturn, Wöger said.
“The difference from the waves and clouds we know here on Earth is that the two interacting fluids are hot plasma — about 6,000 degrees Kelvin and 10,000 degrees Fahrenheit (5,540 degrees Celsius) — moving within a magnetic field that helps create the conditions for the instability to develop,” Wöger said.
By twisting the solar magnetic field, KHI creates energy that can suddenly unleash an explosion.
‘A TRUE GAME-CHANGER’
Wöger called the discovery of solar KHI “a true game-changer,” saying it opens up a new framework for understanding how the sun energizes its atmosphere.
“The sun and sun-like stars are extremely dynamic systems, characterized by a whole spectrum of rapid, explosive events within their magnetic elements. How these explosions are triggered is one of the main frontiers in modern solar physics,” National Solar Observatory astronomer and study co-lead author David Kuridze said.
The KHI manifestation might help explain why the sun’s outer atmosphere becomes as hot as it does and why magnetic energy accumulates and moves around on the solar surface.
The constant twisting motions generated by KHI can gradually build the energy required to trigger coronal mass ejections and solar flares, Kuridze said. Coronal mass ejections are huge bubbles of gas threaded with magnetic field lines that are expelled from the sun’s surface. Solar flares are gigantic explosions on the sun that propel light, energy and high-speed particles into space.
Aside from the science, the researchers admired the beauty of the new close-up views of the sun.
“Maybe ‘magnificent’ comes closest to describing the aesthetics in the images for us,” Wöger said.
“Interestingly, artists have long captured this fluid dynamic intuition in their work. A famous example is Van Gogh’s ‘The Starry Night,’ where the sky’s vortex structures closely resemble turbulent KHI structures,” Kuridze said. “A similar parallel appears in Hokusai’s famous woodblock print, ‘The Great Wave off Kanagawa,’ where the curling crests of the wave echo the iconic shape of KHI billows. It shows how the fundamental geometry of nature deeply resonates with human art.”

Afghanistan currently transits internet traffic to Central Asia, says MCIT
Afghanistan is currently serving as a transit route for internet traffic between South Asia and Central Asia, the Ministry of Communications and Information Technology (MCIT) said, highlighting the country’s growing role in regional digital connectivity.
The ministry said fiber-optic traffic from several South Asian countries is routed through Afghanistan to Central Asian nations via the country’s fiber-optic network.
According to the ministry, nearly $3 billion has been invested in Afghanistan’s fiber-optic and telecommunications sector so far, with expansion efforts continuing.
Officials said Afghanistan offers significant investment opportunities in telecommunications and fiber-optic infrastructure. They added that, alongside expanding domestic communications services, the ministry is working to enhance the country’s capacity to provide transit services for regional countries.
The ministry said Afghanistan is already facilitating the transit of internet traffic from parts of South Asia to Central Asia and stressed that the country’s strategic geographic location positions it as an important digital corridor between the two regions.
“We are currently transiting internet traffic through Afghanistan to South Asian and Central Asian countries,” said Enayatullah Alokozai, spokesperson for the Ministry of Communications and Information Technology. “Afghanistan is a suitable geographical corridor for data transmission.”
Economic analysts say Afghanistan has the potential to become a key hub for regional connectivity. They noted that, in addition to serving as a corridor for energy transmission from Central Asia, the country could also facilitate the large-scale transit of fiber-optic connectivity, internet traffic, and commercial goods.
Representatives of the private sector also said Afghanistan has strong potential to attract further investment in telecommunications and fiber-optic infrastructure. They noted that numerous domestic and international companies are active in the sector, creating direct employment opportunities for thousands of Afghans.

New AI tool helps Afghans identify visa pathways
A veteran-led organisation has launched a new artificial intelligence-powered platform designed to help Afghans navigate complex visa and relocation options as thousands remain stranded or at risk nearly five years after the withdrawal of U.S. forces from Afghanistan.
The Visa Pathways and Relocation Information Center (V-PRIC), developed by AfghanEvac, uses artificial intelligence to guide users through possible immigration and protection pathways based on their individual circumstances.
According to AfghanEvac founder and U.S. Navy veteran Shawn VanDiver, the platform attracted more than 30,000 visits during its first week online.
Users begin by answering questions about their current location, whether they worked with the United States, whether they face security risks, and by providing a brief description of their situation. The system then compares that information with a database covering 124 U.S. visa and immigration categories, including 16 relevant to Afghan applicants, as well as relocation options offered by other countries.
VanDiver said the platform is intended to simplify what is often a confusing and constantly changing immigration process. Before using the service, applicants must acknowledge that it does not provide legal advice.
The launch comes as many Afghans who supported the U.S. during its two-decade military presence continue to face uncertainty. AfghanEvac says policy changes have significantly reduced available relocation opportunities, leaving many applicants unable to progress with immigration cases.
According to the organisation, around 1,100 Afghan allies and their family members remain at the Camp As Sayliyah processing facility in Doha, Qatar, despite many having previously received approval to enter the United States. AfghanEvac says travel restrictions have prevented them from completing the process.
VanDiver said the new tool helps users identify obstacles affecting their applications, including whether delays are caused by legal requirements or government policy, while also highlighting possible next steps.
The platform has been trained using legal decisions, executive orders, policy documents and information gathered through AfghanEvac surveys and guidance materials. The organisation says it will continue updating the system as immigration policies evolve.
VanDiver said the tool could also help applicants avoid actions that may complicate future immigration cases, such as pursuing visa interviews when programmes are temporarily suspended.
AfghanEvac recently surveyed more than 1,100 Afghans between January and July this year. Of the 427 respondents still inside Afghanistan, nearly half reported facing direct security threats. Another 427 respondents were in Pakistan awaiting relocation, with many expressing concerns about possible deportation and limited access to healthcare.
The organisation emphasised that the AI platform is intended to complement, rather than replace, professional legal assistance. It encourages applicants to seek legal advice while using the service to better understand the immigration options available to them.
