Charging time, 10 → 80%
Modelled using the MG 4's actual charging curve, not a flat headline rate.
| Charger | Time (10→80%) | Avg delivered |
|---|---|---|
| 7kW home | 6h 10m | 7.0kW |
| 22kW destination | 3h 56m | 11.0kW |
| 50kW rapid | 52m | 49.7kW |
| 150kW ultra-rapid | 30m | 85.7kW |
| 250kW peak | 30m | 85.7kW |
| 350kW | 30m | 85.7kW |
Charging curve
Maximum power the 4 accepts at each state of charge. The curve drops sharply above 80%, which is why most rapid-charging sessions end there.

About this battery
The MG 4's charging behaviour above is derived from its cell chemistry and pack architecture using our own model — not copied from a third-party test database. Here's what's inside the pack and why it produces the curve you see.
