Huawei unveils EV battery tech with 3,000 km range, 5 minute full charge claim
Huawei has filed a patent for a battery tech that can enable EVs for a single charge range of 3000 km Notify me Huawei has joined the debate about future-generation electric cars with a pretty radical suggestion: a battery system that might charge an EV for more than 3,000 kilometres. The work comes in the guise of a just-filed Chinese patent, which emphasizes a solid-state battery design with high energy density and speed charging. The technical description centres around a nitrogen-doped sulfide electrode configuration, aimed at curbing degradation over time. Huawei claims these cells can deliver 400–500 Wh/kg, which is about three times the energy density of current lithium-ion cells used in most EVs today. In theoretical terms, that kind of density could push a mid-sized electric car to cover roughly 3,000 km before needing a recharge. Interestingly, the required time to recharge the battery from 0-100 percent is claimed to be 5 minutes.

When adjusted to more conservative standards, like the EPA cycle, the estimate drops to around 2,000 km—still far ahead of what most EVs offer. Practicality vs Possibility Building a car to accommodate that level of battery performance involves more than just cramming in tech. This would need a considerably bigger and heavier battery pack, which adds complexity and cost to production and ownership as well. To be clear, Huawei's hypothetical EV would need a battery weighing as much as a small hatchback. That essentially defeats the expense efficiency achieved in previous generations of cars, which EVs are supposed to improve upon. More likely is that manufacturers might apply this technology to build smaller, lighter batteries that still offer respectable range—perhaps 800 to 1,000 km—while improving vehicle dynamics and cost-efficiency. That direction aligns more with the needs of typical users and keeps vehicles within realistic performance and pricing brackets.

Still, even if we can clear technical hurdles, practical adoption ultimately depends on whether the technology can become scalable and affordable, and also be integrated in a way that doesn't compromise usability. Automakers are likely to favour balanced applications of such innovations—improving range and charging times without inflating vehicle size or price. Huawei's patent points to a fascinating future where EVs could, in theory, match or exceed the convenience of internal combustion vehicles. But the usefulness of a 3,000-kilometre EV is debatable when infrastructure, affordability, and real-world habits remain key challenges.

China's BYD launches new hybrid SUV with 800+ mile range, autonomous driving tech
China's largest electric vehicle manufacturer BYD has introduced its most expensive Denza model to compete with BMW and Mercedes-Benz within the luxury segment amid growing competition in the world's largest auto market. Priced between $54,000 and $62,000, the Denza N9 is available in both plug-in hybrid and pure-electric versions. The N9 is powered by an e3 three-electric-motor system, which includes a front AC motor, and two rear permanent magnet motors. The front motor delivers 200 kW (268 hp) and 315 Nm, while the rear motors produce 240 kW (322 hp) and 360 Nm. The official moose test speed is 53.2mi/h. The advanced driving system is equipped with a 128-line lidar, five millimeter-wave radars, 12 ultrasonic radars, and 14 cameras. It offers features like automatic parking in various spaces, remote control parking, emergency lane keep assist, and blind spot monitoring. Under the hood, the N9 boasts of a 2.0T engine producing 152 kW (204 hp) and 325 Nm, along with 46.9 kWh blade battery packs, offering a pure electric range of 125.5 miles (202 km) and a comprehensive range of 809 miles (1,302 km) as per China Light-Duty Vehicle Test Cycle (CLTC) standards. The vehicle accelerates from 0 to 62mi/h in 3.9 seconds, has a minimum turning radius of 4.65 meters, and an NEDC fuel consumption of 6.3L/62mi. The SUV will also come equipped with BYD's self-developed God's Eye autonomous driving system and support on-vehicle drone systems, both introduced in February, as reported by the South China Morning Post. The car enables fast charging, boosting the battery from 30% to 80% in just 19 minutes. BYD chairman and founder Wang Chuanfu emphasized China's ambitions in the luxury EV segment, stating that the country seeks to showcase its ability in not only producing quality vehicles but also in establishing a strong foothold in the high-end market. Last year, the automaker sold approximately 3.84 million plug-in hybrids and pure EVs, securing a 20% share of the global EV market and solidifying its leadership in the segment. Most electric vehicles in China have largely replaced internal-combustion cars, thanks to high-performance batteries, early-stage self-driving technology, and advanced digital cockpits. Global brands once dominated China's premium car market, but local automakers like Li Auto and Xpeng gained ground last year with their intelligent EVs. As a result, Mercedes-Benz saw a 6.7% drop in sales, BMW declined by 13.4%, and Audi's deliveries fell by 9%, according to industry data. Experts have noted that Chinese EV makers are entering the premium segment to move up the value chain and capture higher margins, posing a growing threat to luxury brands like Porsche, Mercedes-Benz, and BMW. BYD is also looking to rival Tesla in the electric vehicle market with the launch of its groundbreaking battery electric vehicle (BEV) platform and ultra-fast charging technology, reportedly capable of delivering an impressive 1,000 kW of power. The 'BYD Super e-Platform' is aiming to showcase charging capabilities that far exceed current industry standards, including Tesla's Supercharger.
