BYD has emerged as one of the largest global EV makers and entered the UK market with the Atto 3, Dolphin, Seal and Sealion. All use Type 2 AC + CCS DC. V2L is standard across the line at 3.6kW. UK volume is growing fast in 2025-2026.
Connector spec by model
- Atto 3 (2023+): Type 2 + CCS. 11kW AC. V2L 3.6kW. 89kW DC peak.
- Atto 2 (2025+): Type 2 + CCS. 11kW AC. V2L. 88kW DC.
- Dolphin (2023+): Type 2 + CCS. 11kW AC. V2L. 88kW DC.
- Seal (2024+): Type 2 + CCS. 11kW AC. V2L. 150kW DC.
- Sealion 7 (2025+): Type 2 + CCS. 11kW AC. V2L. 150kW DC.
V2L across the BYD line
BYD includes V2L (3.6kW from the Type 2 port) as standard on every UK EV in their range, unusual for a value-positioned brand. Compatible with our V2L adapter range. Useful for camping, power tools, holiday-let backup, kettle and fridge during outages.
The Sealion 7 and Seal also support DC V2H (vehicle-to-home) on selected markets, though UK availability of DC V2H wallboxes is still limited as of 2026.
AC charging speed at home
Every BYD EV caps at 11kW AC.
- 11kW three-phase: ~45 miles/hour. 60kWh Atto 3 battery in ~5.5 hours.
- 7.4kW single-phase: ~25-30 miles/hour. Same battery in 8-9 hours.
Battery technology: Blade
BYD's Blade battery is LFP (lithium iron phosphate): different chemistry from typical NMC lithium-ion. Practical implications:
- You CAN charge to 100% routinely without long-term degradation (NMC packs prefer 80% daily limit; LFP doesn't).
- DC peak speed is slightly lower (typically 88-150kW) but the curve is flatter, sustained higher power above 30% state-of-charge.
- Cold-weather performance is somewhat worse: LFP loses more range at -5°C than NMC.
Length recommendations
BYD charge ports are typically at the rear-right (Atto 3, Seal, Sealion) or front-right (Dolphin). UK driveways: 7.5-10m Type 2 cable.
Smart-tariff integration
BYD app integration is improving but not yet at the level of Tesla/Hyundai apps. For Octopus Intelligent integration, pair with Ohme; for solar-PV pair with MyEnergi Zappi.
