Hyundai Kona Electric

Charging curve · consumption · motorway range

We model 2 versions of the Hyundai Kona Electric. The Kona Electric 65 kWh (2024 on) has 65.4 kWh of usable battery and peaks at 105 kW on a DC charger. In this app's model it uses about 180 Wh/km at a steady 100 km/h and 265 Wh/km at 130, so 47% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 40-minute 10-80% charging stop and you have the whole question of how fast to drive.

Which version you have matters

These share a name and not much else that a trip planner cares about. Pack size sets how far you go between stops, and the curve sets how long each one takes.

DC charging curve

Charging power against state of charge, on a charger fast enough not to be the limit. Peak power is 105 kW, but it has halved by about 69% state of charge. That is why a short stop low down the curve usually beats a long one near the top.

Consumption and range by cruise speed

Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 57 + 0.0123 · v² for the Kona Electric 65 kWh (2024 on). The “usable range” column is the honest one for trip planning: it is 100% down to 10%, because nobody arrives on empty.

What the model does not include

• Elevation. The trip planner does account for climbs and descents; the range figures on this page are flat-road, so an alpine route will come out worse than the table.
• Temperature. These are mild-weather numbers. Cold raises consumption and cuts the charging curve. The planner models both. The numbers on this page do not.
• Wind, rain, roof boxes, payload and tyre choice, all of which move real consumption more than most people expect.
• Charger-side limits. The charging times above assume the site can deliver whatever the car asks for. A 150 kW cabinet shared with the car next to you will not.

Where these numbers come from

Hyundai Kona Electric, first generation (2018-2023): the same name as the 2024 car and a different one to plan around: 77 kW peak against 105, so 10-80% takes forty-six minutes instead of thirty-seven, and a long day out needs one more stop or one longer one. Marginally the more efficient of the two at a cruise. Charging hardware did not change across MY19, MY21 and MY22 facelifts, so one curve covers the generation; fitted to EV Database's published figures. Charge curve measured, not drawn: digitized from published Fastned and InsideEVs plots by Morin et al., figshare doi:10.1184/R1/30570653 (CC BY 4.0), then reduced to anchor points that reproduce its charge times to within 2%.

Hyundai Kona Electric, second generation (MY24-25): a 400 V car on its own platform, not E-GMP, and the slowest charger of the Koreans here at 105 kW. Thirty-seven minutes for 10-80% is the number that decides its long trips, not the pack size. Curve fitted to EV Database's published figures.
