BYD Blade 2.0 battery reveals significant inefficiency
15 articles · Updated · The Information · May 7
At the Beijing Auto Show, the battery was reported to deliver 3.8 miles per kilowatt-hour, versus 4.1 for Tesla's Model 3 and 5.0 for Lucid Air Pure.
That implies about 266 miles from a 70kWh pack, compared with 287 for Tesla and 350 for Lucid, meaning BYD needs larger, costlier batteries for similar range.
The weakness could give Western carmakers an opening on price and efficiency, with Ford's planned $30,000 electric midsize pickup cited as one model aiming to challenge Chinese rivals.
China’s EVs are cheap and feature-rich, but is their poor battery efficiency a fatal flaw for global dominance?
With the U.S. market blocked, can China’s EV push into Europe and MENA redefine the global auto industry?
As cars become smart devices, can Western automakers compete with China's integrated 'car-to-home' tech ecosystems?
Scaling Ultra-Fast Charging: BYD’s 1,500 kW FLASH Stations and the Real-World Limits of Blade Battery 2.0
Overview
BYD is rapidly expanding its FLASH charging network in China, with over 4,200 stations installed by early 2026 and a goal of 20,000+ by year-end. These stations deliver ultra-fast charging at up to 1,500 kW, enabling the Blade Battery 2.0 to charge from 10% to 70% in just 5 minutes, even performing well in extreme cold. However, the battery's passive cooling system requires the Battery Management System to throttle charging speeds during consecutive fast charges, causing slower charging on long trips. BYD's shift to LMFP chemistry boosts energy density and range but introduces manganese-related degradation risks, which the company mitigates through advanced material engineering. Meanwhile, competitors like Geely use active cooling to maintain consistent fast charging, highlighting a trade-off between safety, cost, and sustained performance.
