Charging time, 10 → 80%
Modelled using the Hyundai Kona Electric's actual charging curve, not a flat headline rate.
| Charger | Time (10→80%) | Avg delivered |
|---|---|---|
| 7kW home (single-phase) | 6h 29m | 7.0kW |
| 22kW destination (three-phase) | 4h 22m | 10.4kW |
| 50kW rapid | 57m | 47.8kW |
| 150kW ultra-rapid | 42m | 65.5kW |
| 250kW peak | 42m | 65.5kW |
| 350kW | 42m | 65.5kW |
Why the AC numbers look low at home
The Kona Electric is rated at 10.4kW, but that figure needs a three-phase supply — which almost no UK home has. British houses are single-phase (230V, typically 32A), so a home charger delivers around 7.4kW and the car can't exceed it. The 10.4kW rating only matters at 11kW and 22kW destination chargers.
None of this affects rapid charging: DC bypasses the onboard charger entirely, which is why the 100kW figure above is unaffected.
Charging curve
Maximum power the Kona Electric accepts at each state of charge. The curve drops sharply above 80%, which is why most rapid-charging sessions end there.

Second-generation Kona Electric. Although Hyundai-Kia's flagship EVs use SK On 800V cells, the Kona uses a 400V pack with LG NMC 622 pouch cells and a deliberately conservative BMS calibration that caps peak DC at 100kW. Optimised for range and durability rather than rapid charging.
