The issue of energy replenishment for new energy vehicles (NEVs) has always been one of the obstacles hindering their development. After all, the charging time for many NEVs often takes 30 minutes or more. During emergencies or holidays, queuing for charging remains a common sight. The reasons for these queues are twofold: insufficient charging infrastructure and excessively slow charging speeds!
Recently, BYD unveiled its ultra e-Platform technology, achieving a charging power of 1 megawatt (1,000 kW)—the highest peak charging speed in mass-produced vehicles worldwide at 2 km per second. This sets a global benchmark for mass-produced EVs: a 5-minute flash charge delivers 400 km of range.
Achieving “charging at gas-pump speed” requires simultaneous ultra-high voltage and ultra-high current charging.
The newly unveiled ultra e-Platform represents the world’s first mass-produced passenger vehicle “Full-Domain 1000V High-Voltage Architecture,” upgrading battery, motor, power electronics, and air conditioning systems to 1000V – truly ushering EVs into the kilovolt era.
BYD has also officially launched its “Flash Charging Battery,” establishing ultra-high-speed ion channels from cathode to anode. This innovation:
- Reduces internal resistance by 50%
- Enables 1000A charging current
- Achieves 10C charging rate
– setting new global benchmarks across all parameters
Powered by ultra-high 1000V voltage and ultra-high 1000A current, the “Flash Charging Battery” achieves a world-leading 1 megawatt (1000kW) charging power for mass-produced vehicles, officially ushering in the “Megawatt Charging Era”.
With megawatt flash charging enabling a world-record peak charging speed of “2 km per second”, it delivers an unparalleled charging experience for users.
Currently, the fastest energy replenishment method for pure electric vehicles is actually battery swapping, which takes approximately 3 minutes to complete. However, the battery swap model has its own limitations.
For example, a single battery swap station typically holds 20–30 batteries. If there’s a queue, the station can only serve 20–30 vehicles before running out of charged batteries, requiring time to recharge them. Thus, each station has a theoretical daily service cap of around 400 swaps. In contrast, flash charging faces no such limitation—it can charge vehicles indefinitely without battery inventory constraints.
Additionally, battery-swappable vehicles require standardized battery packs and chassis designs, meaning only a handful of brands currently support this model. Most automakers do not adopt battery swapping, limiting its widespread adoption.
