Chinese company unveils new tech that could revolutionize electric vehicles: 'Truly amazing'
New electric vehicle battery technology that could put an end to range anxiety has been unveiled at the 2025 Shenzhen International Battery Fair in China.
Among Chinese battery manufacturer SEVB's announcements was its Star Chaser 2.0 battery system that delivers over 93 miles of range from just one minute of charging, according to a report by Interesting Engineering.
Electric vehicles are a major component in shifting the world away from dirty fuels and adopting clean energy alternatives. These machines don't produce any tailpipe emissions and can run on electricity generated by sustainable sources.
Unfortunately, charging an EV takes significantly longer than filling a tank with gasoline. DC fast chargers, which are some of the fastest, still take between 20 minutes and an hour to get a battery up to 80%.
Battery charging speeds are graded with a "C" rating. SEVB's original Star Chaser, which was launched in 2022, was groundbreaking at the time with 4C charging rates.
The company's new Star Chaser 2.0 uses a combination of liquid cooling, flexible printed circuits, and added safety features to achieve the incredible feat of charging at 12C, the report explained.
The Xinxingchi 2.0 Kiloamp Extreme Charging Edition is essential to the technology, allowing the battery to be charged with a record 1400 A current when paired with a vehicle that has a 1,000-volt system.
The resulting 1.4 megawatt flash-charging succeeds in making EV charging as fast as refueling a traditional vehicle, which could tilt the scales in favor of EVs for consumers who have been on the fence about upgrading.
The company also announced the Xinxingchi 2.0 Long Range Edition, which charges at 6C but offers over 500 miles of range.
Being able to charge quickly can make electric vehicles far more appealing, but there are already inherent benefits to the technology that make them better than more typical cars powered by internal combustion engines.

EVs are extremely energy efficient, converting up to 91% of the energy from the battery and regenerative braking system into forward motion. Gasoline-powered vehicles only get about 25% energy efficiency from burning dirty fuels.
That efficiency also means that the annual costs to fuel an electric car will be significantly lower. A 2018 study from the University of Michigan found that EVs cost around $485 to fuel every year, compared to $1,117 in annual fuel costs for a gasoline vehicle.
Plus, homes with a solar panel system and battery storage allow EV owners to charge their vehicles with clean energy and reduce those costs even further. EnergySage offers expert advice and quote comparisons to help consumers who are interested in upgrading.
Interesting Engineering added that SEVB is also trying to keep their products at a competitive price, so that the three-year cost of EV ownership will be lower than that of a gasoline-powered car.
Commenters on the Interesting Engineering report seemed hopeful for the future of this technology.
"Sounds like truly amazing technology," one person said. "Let's hope this battery can be manufactured at scale."

Federal Transportation Minister Freeland 'dismayed' about choice of Chinese shipyard
VICTORIA — Federal Transportation Minister Chrystia Freeland says she is "dismayed" that BC Ferries has contracted a Chinese state-owned shipyard to build four new vessels in the current geopolitical context that includes "unjustified" tariffs on Canada. Freeland says in a letter sent to provincial Transport Minister Mike Farnworth that she expects BC Ferries to inform her about all measures that it plans to take to "mitigate any security risks," including cybersecurity problems that might arise from the decision. BC Ferries announced earlier this month that it has contracted China Merchants Industry Weihai Shipyards to build four new major vessels following a five-year-long procurement process that did not include a Canadian bid. Freeland adds she is "surprised" that BC Ferries does not have a mandate for an "appropriate level" of Canadian content in the procurement given the value of the contract, although the dollar figure hasn't been made public. Farnworth says in a statement that the ministry is reviewing the letter, adding that he has spoken with Freeland about the need to bolster B.C.'s shipbuilding industry. BC Ferries says in a statement that the Chinese bid was "the strongest bid by a significant margin" and that security is a "top priority," adding that all sensitive systems will be sourced separately and independently certified before the vessels enter service.

Why India's Budding EV Sector Has Opened Its Doors To China
For decades, China has driven the lion's share of oil demand growth thanks to its remarkable economic boom and large population. However, China is now losing its prominence in global oil markets due to a dramatic slowdown in its economy coupled with the country's ongoing electric vehicle revolution. Last year, nearly half of all new cars sold in China were electric vehicles, including both battery-electric and plug-in hybrid electric vehicles. Indeed, China's rapid adoption of EVs, as well as rapid growth of high-speed rail and natural gas trucks, is displacing traditional fossil fuel demand, with the International Energy Agency (IEA) predicting that China's oil demand will peak as early as 2027. Ironically, the country that is taking over China's mantle in world oil markets is also aspiring to follow in its EV footsteps: India. Unlike China, India's EV sector is still at its infancy, with electric vehicles accounting for just 2.5% of all cars sold in the country in 2024. However, India has big EV ambitions, with the Indian government having set a target for EVs to make up 30% of total passenger vehicle sales by 2030. To accomplish this, India's EV sector is forging close ties with Chinese EV manufacturers at a time when Washington has been keeping Chinese EV giants at bay. India is relying on Chinese EV tech to bridge the gap until the domestic sector is ready to compete on the global stage. Industry analysts note that without access to Chinese technologies—including batteries, drivetrain components, and EV software—India would likely face slower product rollouts, limited model variety, and higher costs during its growth phase. This marks a clear pivot from just a few years ago, when India restricted the operations of firms like BYD and banned popular Chinese apps such as TikTok and Shein after deadly clashes at the New Delhi appears to be taking a more calculated stance. In March, the government reduced tariffs on over 35 EV components, many of which are imported from China, making it easier for automakers to source critical parts. A few weeks later, India's Ministry of Heavy Industries unveiled a new EV policy slashing import duties on fully built EVs from 110% to 15%, provided manufacturers invest and set up local production. This dual-pronged approach aims to attract international players while building out domestic supply chains. Experts view these shifts as pragmatic. Leading Indian EV makers—such as Tata Motors, Ola Electric, and Mahindra & Mahindra—continue to depend on Chinese vendors for components like battery cells, power control units, and electric motors, even though assembly is carried out in India. 'The aim is to build a resilient domestic ecosystem, not to isolate it, unlike the more aggressive decoupling seen in the U.S. with China,' said Shubham Munde, senior analyst at intelligence firm Market Research Future. Yet this growing alignment between Indian and Chinese EV sectors is creating both opportunity and competition. MG Motor—a joint venture between India's JSW Group and China's state-owned automaker SAIC—has managed to double its market share over the past year, putting pressure on homegrown giants like Tata Motors. Its model, the MG Windsor, is now India's top-selling electric car, highlighting how joint ventures are gaining traction. At the same time, India's EV landscape remains deeply fragmented. According to Bernstein Research, just four legacy automakers dominate 80% of the electric mobility market, leaving over 150 EV startups struggling to establish a foothold in an increasingly competitive space. Government policy appears to be playing an outsized role in the EV trajectories of different countries. In its 2025 Electric Vehicles Outlook, Bloomberg New Energy Finance (BNEF) cut both its near-term and long-term passenger EV adoption outlook in the United States for the first time ever, citing key policy changes including rollback of national fuel-economy targets as well as the removal of supportive elements of the Inflation Reduction Act (IRA) by the Trump administration. In contrast, S&P Global Mobility has forecast strong growth for India's nascent EV sector, projecting that production of battery-electric passenger vehicles will increase by 140% year-over-year in 2025 to roughly 301,400 units. That would represent about 6% of the estimated 5.16 million passenger vehicles expected to be built in India that year. Still, the road to India's 2030 goal may be steep. According to S&P, India would need to boost EV adoption by approximately 380 basis points annually to reach 30% market share—nearly double the current growth rate of around 200 basis points per year since 2021. Compounding the challenge is the lack of a unified long-term roadmap and the pending expiration of several state-level EV incentive programs.
