Last week, BYD announced a breakthrough feature enabling its new Seal Ultra model to recharge from 10% to 80% state‑of‑charge in under five minutes—a feat that sent BYD’s share price up nearly 12%. “We’ve effectively halved charging times compared to today’s best EVs,” said BYD Chief Engineer He Fei, underscoring the significance of this leap for electric mobility.
BYD’s ultra‑fast charging capability stems from its proprietary 800‑volt electrical architecture combined with the Blade Battery cell‑to‑pack design and an advanced liquid thermal management system. Together, these innovations minimize internal resistance and heat buildup, allowing sustained high charging currents without accelerating battery degradation—key factors in safely achieving sub‑5‑minute top‑ups.
While that sub‑5‑minute milestone headline sounds fancy, charging speed alone doesn’t tell the whole story. Range, battery health, charging infrastructure compatibility, and cost per kWh are equally critical factors for engineers and enthusiasts weighing their next EV purchase.
How Charging Speed Is Measured
Industry standard benchmarks typically report time to recharge from 10%–80% state‑of‑charge (SoC) using a high‑power DC fast charger. This 20–80% window minimizes slow tapering at high SoC and aligns across manufacturers.

Quick Charging Times for Popular EVs
Beyond the top performers, many popular EVs deliver respectable fast‑charging capabilities; here’s a snapshot of charge times for several widely driven models.
- Tesla Model 3 Standard Range+: 20–80% in 23 minutes (250 kW)
- Chevrolet Bolt EUV: 20–80% in 31 minutes (55 kW)
- Volkswagen ID.4: 20–80% in 30 minutes (125 kW)
- Rivian R1T: 20–80% in 25 minutes (200 kW)
EVs Known for Slower Charging
Despite strong range figures, some models lag in charging speed:
- Mini Cooper SE: 20–80% in 45 minutes
- Hyundai Kona Electric: 20–80% in 40 minutes
- Ford F‑150 Lightning (Standard Range): 20–80% in 38 minutes
Why Charging Speed Isn’t Everything
Rapid top‑up times reduce downtime, but real‑world use demands balancing charging rate with battery longevity, infrastructure availability, and total range. As BYD’s innovation underscores, next‑gen battery chemistry and ultra‑high‑power charging infrastructure are converging to redefine EV refueling. For engineers evaluating EV adoption or infrastructure investments, charging speed remains a headline metric – but total cost of ownership, network resilience, and user experience ultimately drive sustainable electrification.
