Question 1

How much does it cost to charge an EV in Singapore?

Accepted Answer

Charging an EV at home in Singapore costs approximately S$0.30/kWh. A Tesla Model 3 with a 60 kWh battery costs ~S$18 for a full charge, giving ~500km of range. Public AC charging costs ~S$0.55/kWh and DC fast charging ~S$0.70/kWh. For an average driver doing 1,500km/month, home charging costs around S$60/month.

Question 2

Is home charging cheaper than public charging in Singapore?

Accepted Answer

Yes, significantly. Home charging via SP Group at S$0.30/kWh is roughly half the cost of public AC charging (S$0.55/kWh) and less than half the cost of DC fast charging (S$0.70/kWh). Over a year, home charging for 1,500km/month saves around S$450 compared to public charging.

Question 3

How many kWh does a Tesla Model 3 use per 100km?

Accepted Answer

The Tesla Model 3 RWD uses approximately 12.2 kWh per 100km (60 kWh battery / 491 km WLTP range). The Long Range variant uses around 12.4 kWh/100km. Real-world efficiency varies with driving style, air-con use, and traffic conditions — expect 13–15 kWh/100km in typical Singapore driving.

Question 4

How much can I save driving an EV vs petrol car in Singapore?

Accepted Answer

A typical driver covering 1,500km/month saves around S$380/month with an EV compared to a petrol car. Home charging costs ~S$60/month vs ~S$444 for petrol at S$2.96/L with 10L/100km efficiency. Over a year, that's over S$4,500 in fuel savings alone — before considering lower servicing and road tax.
