You’ve seen the signs: 50 kW rapid chargers, 150 kW+ ultra‑rapid hubs. But is faster actually better? For UK drivers in 2025, speed needs to justify cost, convenience and battery wear. Here’s a deep dive to help you decide.
What’s the Difference?
Rapid charging ranges from 50 kW to 149 kW, adding roughly 80% battery in 30–40 minutes. Ultra‑rapid starts at 150 kW and now reaches 350 kW, capable of 10–15 minute top-ups if your EV supports it.
For example, the Nyobolt prototype hit 10–80% in under 5 minutes using 350 kW tech (cam.ac.uk), though consumer cars take longer.
How Much Are You Paying?
According to the AA’s June 2025 EV report, typical rapid sessions cost around 74p/kWh, while ultra‑rapid is 78p/kWh on average (fleetnews.co.uk).
Here’s a quick cost breakdown per 60 kWh charge:
- Rapid (74p/kWh): ~£44
- Ultra‑rapid (78p/kWh): ~£47
Is It Worth It?
Save 15–20 minutes? For long drives or business users, ultra‑rapid is game‑changing. But for daily journeys, the speed doesn’t justify the cost. Slow charging overnight costs around 27p/kWh—about 8p/mile (gov.uk).
Battery Impact: Myth vs Reality
Yes, rapid and ultra‑rapid charging stress batteries. Studies show it can accelerate degradation by about 3–10% after 300 cycles (Oxford University). But modern EVs with smart battery management systems reduce that risk.
Tips to protect your battery:
- Charge mostly to 80%
- Use fast or rapid when convenience matters
- Avoid charging when battery is very hot
When Ultra‑Rapid Makes Sense
- Long-distance trips: Fewer stops, faster progress
- Fleet drivers: Higher uptime and productivity
- Emergencies: Low battery and tight schedules
Where to Find Them in the UK
Ultra‑rapid hubs are expanding nationwide at Gridserve, InstaVolt Super Hubs, and BP Pulse stations. Tesla, Fastned, and Ionity also offer 350 kW charging at select locations (bppulse.com).
Use the ONEEV app to compare prices and availability in real-time.
Stay Secure While Charging
Scammers sometimes target chargers with fake QR codes or tampered readers. For secure transactions, stick to the ONEEV app.
Final Word
Ultra‑rapid is impressive, but not always necessary. For most UK drivers, mastering the mix of home, rapid, and occasional ultra‑rapid charging is the sweet spot. Stay charged, drive smart, and save both time and money.
