Flash Charging: Technology Changes the World
On March 5, 2026, BYD held the “Flash Charging China, Changing the World” launch conference at the Shenzhen Universiade Center Gymnasium. The company officially unveiled its second-generation Blade Battery and flash charging technology, setting a new global record for the fastest charging speed among mass-produced vehicles. The battery utilizes cell-to-body (CTB) integrated technology, achieving a system energy density of 480Wh/kg. It supports 800V/1000V high-voltage platforms and 8C ultra-fast charging technology, allowing for 400 kilometers of range with just a 5-minute charge. Charging from 10% to 70% takes 5 minutes, and reaching 97% requires 9 minutes, with peak charging power ranging from 480kW to 1000kW. The individual cell energy density is between 160Wh/kg and 210Wh/kg, with a cycle life exceeding 4500 cycles.
After 500 flash charging cycles, the battery successfully passed needle penetration tests at 70% SOC and 96.4% SOC under flash charging conditions, with no smoke, fire, or explosion after a two-hour rest period. It also withstood a bottom impact test at 10 times the new national standard (1500J impact). At -30°C, charging from 20% to 97% takes only 3 minutes longer than at room temperature. This breakthrough effectively addresses the global challenges of “slow charging” and “difficult low-temperature charging” in the first half of electrification, marking a perfect conclusion to that phase.
The most groundbreaking breakthrough of the second-generation Blade Battery lies in its charging speed:
| Charging Scenario | Charging Time | State of Charge Change |
|---|---|---|
| Room Temperature | 5 minutes | 10% → 70% |
| Room Temperature | 9 minutes | 10% → 97% |
| Extreme Cold at -20°C | 12 minutes | 20% → 97% |
| Extreme Cold at -30°C | Approx. 12 minutes | 20% → 97% |
Additionally, BYD announced the “Flash Charging China” strategy, aiming to build 20,000 flash charging stations nationwide by the end of the year, providing users with greater freedom and convenience in charging. With this, the era of flash charging for new energy vehicles has officially begun.
During the initial design phase, consideration was given to the potential impact on the power grid if existing charging stations were replaced with megawatt-level chargers. The standard configuration for flash charging stations includes a 2.1MVA main unit + two ultra-fast discharge energy storage battery cabinets + two charging terminals.
Sliding Rail Suspension T-Type Post Flash Charging Pile: The charging gun and cable are suspended, keeping them in the air at all times. This prevents tangling and ensures they never drag on the ground, maintaining a cleaner environment. Equipped with a zero-gravity charging gun, it can be operated effortlessly with one hand. The sliding rail design allows for smooth left-right movement, enabling flexible charging regardless of which side the drawer opening is on.
High voltage DC contactors play an important role in the field of flash charging. Good quality and long life high-voltage dc contactors with CE and UL approvals are the first choice for fast charging developers. Hotson EVHA series: such as EVHA600, EVHA800, EVHA1000,etc. The load voltage of this series of products is 12-1500Vdc, and there are a variety of current specifications to meet the application requirements of different fast charging.
Hotson is committed to providing efficient, safe high-voltage DC contactors for flash charging solutions. For consultation or more information, please visit our website or contact our sales team directly. We look forward to working with you to promote industry development together!
