BYD Announces Second-Generation Blade Battery and High-Speed Charging Network

BYD has unveiled its second-generation Blade Battery alongside a new charging system it calls FLASH Charging Technology, claiming a new record for electric vehicle charging speed. The announcement was made in Shenzhen, China, on March 6, 2026, and marks what the company describes as its most significant battery development since the original Blade Battery launched in 2020.

The company says the new battery can charge from 10% to 70% state of charge in five minutes, and reaches 97% in nine minutes. In temperatures as low as -30°C, BYD says the time required to charge from 20% to 97% increases by only three minutes compared to charging at room temperature. That cold-weather figure is likely to draw attention in Northern European and North American markets, where low-temperature battery degradation has been a persistent source of consumer dissatisfaction with electric vehicles.

BYD Chairman and President Wang Chuanfu framed the announcement as a direct response to two problems the electric vehicle industry has not fully resolved: slow charging speeds and reduced battery performance in cold weather. Range anxiety and long queues at public charging stations during public holidays have been cited in consumer research across multiple markets as among the most significant barriers to EV adoption. Wang said the industry's failure to adequately address these concerns had imposed both practical and psychological costs on drivers.

Battery Design

BYD says the second-generation Blade Battery is the product of six years of research and development. The central engineering challenge the company sought to resolve was the long-standing trade-off between fast charging and high energy density — in conventional battery design, optimising for one has typically come at the expense of the other. BYD says it has increased energy density by 5% over the first-generation Blade Battery while simultaneously improving charging speed, a combination the company is presenting as a material step forward.

To achieve this, the battery uses a structure BYD calls a "Lithium-Ion High-Speed Channel," which the company says minimises internal heat generation during rapid charging. This is paired with what BYD describes as a "Full-Spectrum Intelligent Thermal Management System," designed to regulate temperature across a wide range of conditions and preserve consistent performance whether in freezing winters or high summer heat.

The company says the battery has passed a series of safety tests that exceed China's national standards, including tests relevant to thermal runaway — the failure mode in which a battery cell overheats uncontrollably, potentially triggering a fire. BYD has made safety a recurring theme in its battery communications, and the first-generation Blade Battery was partly marketed on its resistance to this failure mode.

The second-generation battery will make its commercial debut in the DENZA Z9GT, a model in BYD's premium DENZA vehicle line. The company says the Z9GT, which also features a lightweight body structure, achieves a range of 1,036 km on a single charge — a figure that, if verified under standard testing conditions, would place it among the longest-range production EVs currently available.

Charging Infrastructure

The battery's high charging speeds require infrastructure capable of delivering power at a corresponding rate. To meet this requirement, BYD has developed a charger it says outputs 1,500 kW through a single connector — a figure it describes as a world record for single-connector charging output. For context, most high-speed public chargers currently in operation deliver between 150 kW and 350 kW, and only a small number of proprietary systems exceed 500 kW.

A central design consideration for ultra-fast charging at this scale is its potential impact on local electricity grids. Charging a vehicle at 1,500 kW places a demand on the grid roughly comparable to powering a small residential street simultaneously. BYD says it has addressed this by pairing each FLASH Charger with an on-site battery energy storage system, which absorbs power from the grid at a slower rate and then discharges it rapidly when a vehicle connects. The company says this approach allows the stations to deliver high-speed charging without requiring costly grid upgrades or creating instability in local power networks.

BYD has also redesigned the physical charging connector. The new unit features a T-shaped pulley mechanism the company calls a "Zero-Gravity" design, which is intended to reduce the effort required to lift and position the connector and to keep the cable off the ground. Public charging equipment has drawn user complaints in multiple markets for being cumbersome, poorly maintained, and difficult to authenticate — issues BYD says the new hardware is designed to address.

BYD plans to build 20,000 FLASH Charging Stations across China by the end of 2026, and says a global rollout will begin in the same period. The company says the stations will be open to all electric vehicles, regardless of brand — a policy that, if maintained, would give the network a broader utility than some manufacturer-operated charging networks that restrict access to their own models.

BYD, headquartered in Shenzhen, is currently the world's largest manufacturer of electric vehicles by sales volume. Founded in 1995 as a battery manufacturer, the company entered the automotive sector in 2003 and has since grown into one of the most closely watched players in the global EV market. In recent years, BYD has expanded aggressively into overseas markets, including Europe, Southeast Asia, and Latin America, where it competes with both established automakers and other Chinese EV manufacturers.

The company introduced the first-generation Blade Battery in 2020. Unlike the nickel-manganese-cobalt chemistries used by several competitors, the Blade Battery uses lithium iron phosphate — a chemistry that trades some energy density for greater thermal stability and a longer cycle life. The structural design of the cell, which is thin and flat like a blade, allowed BYD to pack cells directly into the battery pack without intermediate modules, improving space efficiency and reducing manufacturing complexity.

The FLASH Charging announcement sits within a longer-term strategic vision Wang Chuanfu has described publicly since 2006 under the name the "Three Green Dreams" — a framework centred on solar energy, energy storage, and electric vehicles working as an integrated system. Thursday's Solar-Storage-Charging technology, which combines on-site solar generation, battery storage, and the FLASH Charger into a single station, represents what BYD describes as the most complete expression of that vision to date.

The company has not confirmed pricing for the FLASH Charging network, the cost of the DENZA Z9GT equipped with the second-generation battery, or a specific timeline for which international markets will receive infrastructure first.
