Hyundai Kona Electric Home Charging UK: Cost per Charge, Time & Best Chargers
Vehicle guide
The 65 kWh Kona Electric fills in about 9 hours on a 7 kW wallbox and costs under £5 on an off-peak tariff. No Intelligent Go through the car, so the charger does the work; here's which one.

Charging time estimates
Approximate AC charging times
| Charge window | 3-pin (~2.3kW) | 7kW | 11kW max |
|---|---|---|---|
| 20–80% | 18h 25m | 6h 5m | 3h 50m |
| 0–100% | 30h 45m | 10h 5m | 6h 25m |
Assumes 8% charging losses and rounded 5-minute estimates. 3-pin assumes about 2.3kW; 7kW uses up to 7kW; three-phase only appears when the vehicle can accept more than 7.4kW AC.
Vehicle-specific tariff cost
Hyundai Kona Electric (65 kWh) charging cost at 10,000 miles.
EV electricity only, using 3.7 miles per kWh and assuming every charging kWh reaches the listed lower rate. Household electricity and the postcode-dependent standing charge sit outside these figures.

The hardware
The second-generation Kona Electric (2023 on) has its Type 2 inlet in the nose, centre-left, under a flap in the front panel. Park nose-in and almost any tethered cable reaches; nose-out, you need the cable to run the length of the car. The on-board charger is 11 kW (Hyundai quotes 10.8 kW on recent spec sheets), so a UK single-phase wallbox gives the full 7.4 kW. A Type 2 cable is supplied.
DC peaks at 105 kW on the 65 kWh car.
Variants (2026)
| Variant | Battery (usable) | Max AC | Max DC | WLTP range |
|---|---|---|---|---|
| Kona Electric 48 kWh (156 PS) | 48 kWh | 11 kW | 75 kW | 234 miles |
| Kona Electric 65 kWh (218 PS; Advance, N Line, Ultimate) | 65 kWh | 11 kW | 105 kW | 282–319 miles |
Usable capacities (51 and 68.5 kWh gross). Hyundai UK currently sells the 65 kWh car from about £35,000; the 48 kWh version appears to have been withdrawn from new UK sales in late 2025, so treat it as a used-car option. Real-world range is about 180 and 240 miles.
How long it takes to charge the Kona Electric
The figures below are for the 65 kWh, the version most people buy, with its 65.4kWh usable battery.
20% to 80%, the everyday window
| Supply | Charge time (20–80%) | Range added |
|---|---|---|
| 3-pin socket (~2.3 kW) | ~17 hours | ~145 miles |
| 7 kW wallbox | ~5½ hours | ~145 miles |
| 11 kW three-phase | ~3.6 hours | ~145 miles |
Overnight on single-phase; the 11 kW figure needs a three-phase supply most homes do not have.
0% to 100%
| Supply | Charge time (0–100%) | Notes |
|---|---|---|
| 3-pin socket (~2.3 kW) | ~28½ hours | Emergency use only |
| 7 kW wallbox (single-phase) | ~9 hours | The standard overnight charge |
| 11 kW wallbox (three-phase) | ~6 hours | Only if the house has a three-phase supply |
Costs
The tariff does most of the work. The Kona Electric returns about 3.7 mi/kWh in real-world UK driving.
Cost per full charge (65.4kWh)
| Tariff | Rate | 0–100% | 20–80% |
|---|---|---|---|
| EDF GoElectric | 6.66p/kWh | £4.36 | £2.61 |
| Octopus Intelligent Go | 7.6p/kWh | £4.97 | £2.98 |
| Octopus Go | 9.5p/kWh | £6.21 | £3.73 |
| British Gas EV Power | 9.5p/kWh | £6.21 | £3.73 |
| Standard variable (Ofgem cap) | 26.32p/kWh | £17.21 | £10.33 |
| Public rapid charger | 79p/kWh | £51.67 | £31.00 |
Annual charging cost at 10,000 miles
| Tariff | Cost per mile | Annual cost |
|---|---|---|
| Octopus Intelligent Go | 2.1p/mile | £205 |
| Octopus Go | 2.6p/mile | £257 |
| Standard variable | 7.1p/mile | £711 |
| Public rapid only | 21.4p/mile | £2,135 |
| Petrol equivalent | ~19p | ~£1,900 |
Petrol assumes 40 mpg at £1.45 a litre. The electricity figures are charging only: no standing charge, and no allowance for the 5–10% lost between the wall and the battery.
The gap between the standard rate and a good EV tariff is several hundred pounds a year on typical mileage, and it costs nothing to close. The interactive savings calculator runs the numbers for your mileage; the UK EV Charging Cost Index compares every tariff per mile.
NMC battery and Bluelink's early-start habit
The Kona's NMC pack wants the usual 80% daily limit, set in the car or in Bluelink, with 100% for long trips.
Bluelink's scheduler has an oddity owners describe: the car sometimes starts charging well before the scheduled time, by half an hour to several hours (Kona forums). On a fixed-window tariff that can put part of the charge on the peak rate. If you see it, let the charger hold the schedule instead and leave the car's off.
Smart tariffs and the Kona Electric
Intelligent Octopus Go has no integration with the car, so the scheduling has to come from the charger. That rules in the Ohme Home Pro, Ohme ePod, myenergi zappi, Hypervolt Home 3 Pro, Indra, Andersen and Octopus's own Octopus Charge, and rules out a basic wallbox if you want the 7.6p rate with no manual timers. Hyundai changed its API in 2025 and Octopus told owners the Kona would no longer connect car-side (Kona forums). OVO Charge Anytime lists Hyundai as a beta integration that OVO staff themselves call unreliable (OVO forum). For this car, a smart charger with its own supplier links is not optional if you want the managed rates.
Choosing a charger
Every home charger on this site works with the Kona Electric: Type 2 is universal for UK AC charging. The charger has to carry the tariff, which narrows the choice to the units with supplier integrations.
- Ohme Home Pro at £559: Octopus, OVO and E.ON links; the simplest route to 7.6p/kWh.
- Ohme ePod at £949 installed: the same links in a smaller untethered unit, sold as a fitted package.
- Hypervolt Home 3 Pro at £624: supplier links plus a 7.5 m cable option, which matters for a nose-mounted socket when you park nose-out.
Full head-to-heads are on the charger comparison page, and the smart-tariff chargers guide covers which units talk to which supplier.
Common questions
Can I charge a Kona Electric from a 3-pin plug?
Yes, with a portable charger (not supplied in the UK), at about 2.3 kW; a full 65 kWh charge takes over a day. 3-pin guide.
Does the Kona Electric work with Intelligent Octopus Go?
Not through the car since Hyundai's 2025 API change. A compatible smart charger (Ohme, zappi, Hypervolt and others) makes it work normally.
Does the Kona Electric have Vehicle-to-Load?
Yes, 3.6 kW through an interior socket and an exterior adapter. No vehicle-to-grid.
Is 7 kW enough for the Kona?
Yes. A full charge is about 9 hours and a typical night's top-up under two. Three-phase only helps if the house already has it.
