Frequently asked questions
- How much cheaper is an EV to run than petrol?
- At typical Thai prices — ~16 kWh/100 km at ฿4.5/kWh vs a petrol car at 13 km/litre and ฿40/litre — an EV costs about ฿0.72/km against ฿3.08/km, roughly a quarter of the fuel cost.
- Does this include the car price or maintenance?
- No — this compares energy/fuel running cost only. EVs also tend to have lower servicing costs, but the purchase price and battery are separate considerations.
- What consumption should I use?
- Most EVs use 15–18 kWh/100 km; heavier SUVs more. Check your car's trip computer for a real figure.
