BYD has introduced the second-generation Blade Battery and Flash Charging technology to the Indonesian market. The company claims a new world record for charging speed through the integration of these systems, which allow a vehicle battery to reach full charge in 9 minutes. This addresses a common user frustration with electric vehicles: the time required for charging.
Engineering the Speed
Developed over six years of intensive research, the new battery combines energy density, ion transfer efficiency, and thermal management into a single design. The goal is faster charging, longer range, and increased safety. BYD created the ‘FlashPass’ Ion Transport System to go beyond the capabilities of standard lithium iron phosphate (LFP) batteries.
The technology rests on three main breakthroughs. The ‘Flash-Release’ cathode allows for high density and rapid intercalation. The ‘Flash-Flow’ electrolyte produces high ionic conductivity and fast ion mobility. The ‘Flash-Intercalate’ anode enables high-speed 3D lithium ion intercalation. Together, these elements significantly reduce internal resistance, minimizing heat generated directly from the source.

The new generation incorporates a Solid Electrolyte Interphase (SEI) layer. BYD used molecular engineering and macroscopic structural optimization to create a very thin layer. This provides higher ionic conductivity while remaining very dense to guarantee chemical stability. The battery also features a dynamic self-repairing capability to balance the properties of being thin yet strong.
Blade Battery gen 2 has passed a series of safety tests. Tests included simultaneous Flash Charging and Nail Penetration. Results showed no thermal runaway, smoke, or fire, even after 500 cycles of Flash Charging. The battery also survived a forced short circuit on four cells simultaneously at temperatures exceeding 700°C without igniting.
Flash Charging System
Flash Charging is designed to provide ultra-fast power. The system offers charging power up to 1,500 kW through a single connector. It features a unique overhead T-shaped design. The system can charge from 10% to 70% in about 5 minutes, and reach full capacity or 97% in approximately 9 minutes under normal temperature conditions.
- Plug-and-Charge: For compatible vehicles, users simply connect the connector to start. Authentication happens automatically without needing an app or card.
- T-Shaped Pulley: The overhead rail and pulley system keep the charging cable suspended. This prevents contact with dirty or wet surfaces and keeps the area tidy.
- ‘Zero-Gravity’ Ergonomics: The support system holds the cable weight, making it feel lighter to pull and aim. Paired with a lightweight connector operable with one hand, the process becomes easier.
- Suspended Charging Connector: The connector moves along the overhead rail, making it easier to reach different charging ports on the vehicle.
