Home vs public charging in South Korea — the 5 cheapest EVs to charge
Public and DC fast charging in South Korea is billed per session by each network and varies widely, so we model it the way the kernel does on every cost page: 2.5× the home rate — about ₩313/kWh against ₩125/kWh at home. That is a planning estimate, not any network's tariff. Here is what it does to the 5 cheapest-to-charge models we price in South Korea:
| Electric model | Per 100 km at home | Public (≈2.5× home) | Extra per year if all-public |
|---|---|---|---|
| Hyundai Casper Electric (Inster) Premium Long Range | ₩2,216 | ₩5,540 | +₩432,102 |
| Hyundai IONIQ 6 Standard E-VALUE+ | ₩2,287 | ₩5,717 | +₩445,952 |
| Tesla Model 3 Standard RWD | ₩2,372 | ₩5,930 | +₩462,571 |
| Kia EV4 Standard Air | ₩2,486 | ₩6,214 | +₩484,730 |
| Hyundai Kona Electric Standard E-VALUE+ | ₩2,543 | ₩6,357 | +₩495,810 |
- Hyundai Casper Electric (Inster) Premium Long Range is the cheapest EV to charge in South Korea — ₩2,216 per 100 km at home — and at the public estimate (₩5,540) it still beats the ₩14,077 of petrol a 7 L/100 km car burns over the same distance.
- A Hyundai IONIQ 6 Standard E-VALUE+ draws 16.1 kWh per 100 km, so home charging runs ₩2,287; at the public estimate (₩5,717) it still beats the ₩14,077 of petrol a 7 L/100 km car burns over the same distance.
- For the Tesla Model 3 Standard RWD, public-only charging would add about ₩462,571 a year at 13,000 km/year over charging at home (₩2,372 vs ₩5,930 per 100 km); even then it stays under the ₩14,077 a 7 L/100 km petrol car needs.
- A Kia EV4 Standard Air draws 17.5 kWh per 100 km, so home charging runs ₩2,486; at the public estimate (₩6,214) it still beats the ₩14,077 of petrol a 7 L/100 km car burns over the same distance.
- For the Hyundai Kona Electric Standard E-VALUE+, public-only charging would add about ₩495,810 a year at 13,000 km/year over charging at home (₩2,543 vs ₩6,357 per 100 km); even then it stays under the ₩14,077 a 7 L/100 km petrol car needs.
Even at the 2.5× public estimate, all 5 of these models still undercut the ₩14,077 of petrol a typical 7 L/100 km car burns per 100 km — in South Korea the charging case survives without a driveway. Our 5-year totals on each model page assume 80% home / 20% public charging at this same multiple — these two columns are the ends of that range.
