Charging in 5 Minutes: The Tech Behind BYD's 1,000kW Ultra-Fast System

January 12, 2025 • 10 min read • Charging Technology

The biggest barrier to EV adoption has always been charging time. While a petrol car refuels in 3 minutes, even "fast" EV charging typically requires 30+ minutes for 80% capacity. BYD's ultra-fast charging technology aims to close this gap entirely—delivering 400km of range in just 5 minutes.

The Physics of Ultra-Fast Charging

Charging power (in kW) equals voltage × current. To dramatically increase charging speed, you can either increase voltage, current, or both. Higher current generates more heat, which degrades batteries. The solution? Higher voltage.

The 1,000V Architecture Advantage

BYD's next-gen platform uses 1,000V architecture (vs. the industry-standard 400V). This allows the same power with half the current, reducing heat generation and enabling faster charging without battery degradation.
