The Specs
About the BYD Dolphin Surf 43.2 kWh Boost
-
Battery
43.2 kWh
Usable battery capacity. The number that matters for charging-time maths.
-
DC Peak
85 kW
Limited to slower DC sites — pick a 50 kW rapid, anything faster is wasted.
-
AC Max
11 kW
Standard 11 kW three-phase. Most home wallboxes will charge at full pace.
-
Range gain (estimate)
≈ 106 mi
Rough miles added by a 10–80% fast-charging session (assuming ~3.5 mi/kWh).
How we calculate
The formula, in the open
Charging time is energy needed divided by effective power. We model the typical, warm, healthy case so the number is honest, not optimistic. Read the full methodology for the curve assumptions and sources.
Common Questions
BYD Dolphin Surf — frequently asked
How long does it take to charge a BYD Dolphin Surf 43.2 kWh Boost?
From 10% to 80% in approximately 32 minutes on a 150 kW DC fast charger. From empty to full in around 6h 29m on a 7.4 kW home wallbox. Times above are for a warm, healthy battery — cold packs and busy charger sites can extend them by 10–20%.
What is the BYD Dolphin Surf’s maximum charging speed?
The BYD Dolphin Surf 43.2 kWh Boost accepts up to 85 kW on a DC fast charger and up to 11 kW on AC. Power tapers above 80% state of charge to protect the battery cells.
Can the BYD Dolphin Surf use a 350 kW ultra-rapid charger?
It will work but the car only draws up to 85 kW. A 85 kW or 150 kW charger gives the same speed at lower cost.
How long to charge a BYD Dolphin Surf at home?
On a typical 7.4 kW home wallbox the BYD Dolphin Surf fills from empty in around 6h 29m. Plug in overnight and the charge time stops mattering.
Is it bad to charge the BYD Dolphin Surf to 100%?
For day-to-day driving most manufacturers recommend an 80% ceiling on lithium-ion (NCM/NCA) chemistries, and 100% on LFP. Charge to 100% before a long trip and use the full range that day.
