China’s EV Industry Accelerates Fast-Charging Race to be under 10 minutes

• Chinese EV makers are racing to deliver ultra-fast charging (10%–97% in under 10 minutes), intensifying competition.

• Safety, durability, and battery lifespan remain critical concerns despite speed gains.

• Rising consumer demand is pushing fast charging toward industry standardization.

• Cost control is crucial as advanced technology increases expenses.

• Slumping domestic EV sales heighten pressure to innovate while maintaining affordability.

  
  

China’s electric vehicle (EV) industry is intensifying competition in fast-charging battery technology, with major players unveiling systems capable of charging from 10 per cent to as high as 97 per cent in under 10 minutes. However, industry leaders caution that the pursuit of ultra-fast charging must not compromise battery safety, durability, or cost efficiency. The technology race comes at a time when China’s domestic EV market faces a notable slowdown, adding further pressure on manufacturers to innovate while maintaining affordability.

Rapid Technological Advances in Fast Charging

The latest developments in China’s EV sector were highlighted at a major auto show, where leading battery and vehicle manufacturers showcased new-generation technologies.

BYD, China’s EV market leader, presented its comprehensive ecosystem approach by setting up booths dedicated to its vehicles, batteries, and autonomous driving systems. Earlier in March, the company unveiled its upgraded Blade Battery 2.0 alongside its Flash Charging technology. The innovations claim to increase an EV’s charge from 10 per cent to 97 per cent in less than 10 minutes—marking a significant leap in charging efficiency.

Just days before the auto show, Contemporary Amperex Technology Co. Limited (CATL), the world’s largest EV battery producer, introduced upgraded battery technologies featuring lighter battery packs and faster charging modes. These advancements position CATL squarely in the intensifying race for charging speed leadership.

By comparison, foreign EV brands reportedly still require around 20 minutes to charge from 10 per cent to 80 per cent, underscoring the rapid pace of advancement among Chinese manufacturers.

Balancing Speed with Safety and Durability

Despite the technological momentum, industry executives have emphasized caution.

During CATL’s launch event, Chief Technology Officer Gao Huan expressed confidence in the company’s ability to balance charging speed with battery durability. However, he reiterated earlier remarks made in March 2025, warning against sacrificing reliability, lifespan, and safety in pursuit of excessively fast charging.

Similarly, Markus Fallbohmer, head of high-voltage battery and energy module production at BMW, stated in early April that the company would not compromise key battery performance factors merely to accelerate charging times.

At EV start-up Xpeng, Vice-President for Powertrain Jacky Gu Jie highlighted the chemical limitations inherent in battery materials. He noted that frequent fast charging could damage batteries due to the nature of certain metals used in battery chemistry. Nevertheless, Gu emphasized that fast-charging-enabled batteries would be “over-designed” to ensure that drivers would not encounter problems during normal use.

“The competitive landscape isn’t very friendly these days,” Gu observed. “If you don’t keep improving, others will.”

Rising Demand for Speed

Market demand appears to be reinforcing the industry’s rapid push toward faster charging.

A sales representative from battery maker CALB, surnamed Liu, reported that between 60 and 70 per cent of customers have already requested faster charging solutions. This growing consumer expectation is influencing product development strategies across the sector.

Ethan Zhang, an equity research analyst at Nomura, predicted that fast charging would soon become a standard feature in EVs. However, he cautioned that marginal improvements may yield diminishing returns once consumers become accustomed to fast-charging capabilities.

Yale Zhang, managing director at Shanghai-based consultancy Automotive Foresight, argued that charging times of five to 10 minutes would need to become an industry norm if EV manufacturers hope to persuade petrol car drivers to switch to electric vehicles. Achieving parity with conventional refuelling times is widely seen as critical to accelerating EV adoption.

Cost Pressures and Competitive Realities

While performance enhancements dominate headlines, cost remains a decisive factor.

Xpeng’s Gu stressed that advanced technology inevitably increases production costs. “Cost is still the most important factor in all kinds of competition, rather than performance,” he said. He added that while companies must demonstrate technological strength, they cannot afford to ignore expense management.

This balancing act between innovation and affordability is particularly important given current market conditions.

Market Headwinds

China’s domestic EV sales fell sharply in the first quarter, declining 23.8 per cent year on year to approximately 2 million units, according to data from the China Association of Automobile Manufacturers. The slowdown reflects growing consumer caution following the halving of the 10 per cent sales tax exemption on vehicle purchases.

The downturn has intensified pressure on manufacturers to differentiate themselves through technological breakthroughs such as ultra-fast charging, even as they grapple with cost constraints and softer demand.

China’s EV industry is entering a phase where charging speed is becoming a central battleground. Companies are racing to deliver five- to ten-minute charging solutions that could rival the convenience of petrol refuelling. However, executives across the sector acknowledge that technological ambition must be balanced with safety, durability, and affordability.

As the market adjusts to policy changes and softer sales, the firms that successfully align innovation with cost discipline are likely to emerge strongest in the next phase of competition.
