|---|---|---|---|---|
| 3-pin domestic (UK) | 2.3 kW | AC | 0–100% | 29h 48m |
| Home wallbox 7 kW | 7.4 kW | AC | 0–100% | 9h 16m |
| Three-phase home 11 kW | 11 kW | AC | 0–100% | 6h 14m |
| Three-phase home 22 kW | 22 kW | AC | 0–100% | 6h 14m |
| Public AC destination 22 kW | 22 kW | AC | 0–100% | 6h 14m |
| Rapid DC 50 kW | 50 kW | DC fast | 10–80% | 1h 01m |
| Rapid DC 100 kW | 100 kW | DC fast | 10–80% | 30 minutes |
| Fast DC 150 kW | 150 kW | DC fast | 10–80% | 22 minutes |
| Tesla Supercharger V3 | 250 kW | DC fast | 10–80% | 22 minutes |

The Specs
About the MG MG4 Long Range
-
Battery
61.7 kWh
Usable battery capacity. The number that matters for charging-time maths.
-
DC Peak
140 kW
Pairs perfectly with a typical 150 kW motorway rapid.
-
AC Max
11 kW
Standard 11 kW three-phase. Most home wallboxes will charge at full pace.
-
Range gain (estimate)
≈ 151 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
MG MG4 — frequently asked
How long does it take to charge a MG MG4 Long Range?
From 10% to 80% in approximately 22 minutes on a 150 kW DC fast charger. From empty to full in around 9h 16m 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 MG MG4’s maximum charging speed?
The MG MG4 Long Range accepts up to 140 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 MG MG4 use a 350 kW ultra-rapid charger?
It will work but the car only draws up to 140 kW. A 140 kW or 150 kW charger gives the same speed at lower cost.
How long to charge a MG MG4 at home?
On a typical 7.4 kW home wallbox the MG MG4 fills from empty in around 9h 16m. Plug in overnight and the charge time stops mattering.
Is it bad to charge the MG MG4 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.
