BYD, a leading electric vehicle (EV) manufacturer, has announced a breakthrough in battery and charging technology designed to eliminate a major consumer concern: long recharge times. The company’s new second-generation blade battery, coupled with its flash charging system, promises to deliver speeds comparable to filling a gasoline car.
Ultra-Fast Charging Capabilities
The core of this advancement is the ability to charge an EV from 10% to 70% capacity in just five minutes. Further, a full charge from 10% to 97% can be achieved in nine minutes – a speed BYD claims is a “world record” for mass-produced charging systems.
The performance is maintained even in extreme weather, with vehicles able to reach 97% charge from 20% in just 12 minutes at temperatures as low as -22°F (-30°C). This addresses a common issue with EV charging, where cold weather often reduces efficiency and increases recharge times.
Battery Specifications and Range
While details remain limited, BYD indicates the new battery will offer a maximum range of up to 644 miles (1,036 km). The flash chargers operate at an impressive 1,500 kW capacity, significantly exceeding the 1,000 kW output of conventional chargers.
Deployment and Warranty Improvements
BYD plans to deploy 20,000 flash chargers across China by year-end, with over 4,200 already operational. The company has also improved the battery’s longevity and warranty coverage. The new battery is guaranteed to retain at least 87.5% of its capacity after two years or 31,069 miles (50,000 km). Over six years or 93,206 miles (150,000 km), the capacity should remain above 77.5%, and at eight years, it will still hold at least 72.5%. These retention rates are 2.5% higher at each stage compared to the first-generation battery.
This technology directly confronts a key barrier to EV adoption: the inconvenience of slow charging. BYD’s solution could make EVs more appealing to a broader range of consumers, particularly those who remain hesitant due to range anxiety and long recharge times.
