This is where EVs win most clearly:
| Type | Cost per km (approx.) |
|---|---|
| Petrol | ~2–3 THB/km |
| EV (overnight home charge) | ~0.5–0.9 THB/km |
| EV (fast public charging) | ~1.5–2.5 THB/km |
Example: driving 1,500 km/month — petrol costs ~3,000–4,500 THB, while a home-charged EV costs ~750–1,350 THB.
Overall comparison
| Topic | Petrol | EV |
|---|---|---|
| Fuel cost | Higher | Much lower |
| Maintenance | Fluids/filters/oil | Less (fewer moving parts) |
| Purchase price | Varied | Some pricier, but incentives exist |
| Long trips | Quick refuel, many stations | Plan charging stops |

Verdict
If you drive in the city and can charge at home, an EV is usually cheaper long term thanks to lower fuel and maintenance. For frequent long trips without home charging, petrol still wins on convenience.
Figures are approximate — they depend on the model, fuel/electricity prices and driving habits.

Frequently asked questions
- Can I charge an EV at home?
- Yes, with a wall charger and a suitable meter. Overnight home charging is cheapest; fast public charging is convenient but costs more per unit.

- Modern batteries are built to last years; most makers warrant the battery for around 8 years or a set distance. Degradation is gradual, not sudden.
