Frequently asked questions
How much does it cost to charge an EV?
- It depends on your car's battery size and your electricity rate. For example, charging a Tesla Model 3 (RWD) from 20% to 80% costs about $10.33 at a typical residential rate.
How long does it take to charge an electric car?
- Charging time depends on the charger's power and how much energy you need. A home charger is slower than public DC fast charging, so a full top-up can range from under an hour on a fast charger to several hours at home in Singapore.
How is the charging cost calculated?
- We multiply the energy needed — your battery size times the difference between your target and current charge level — by your electricity rate per kWh. Charging time is that energy divided by the charger's power in kW.
