How much electricity does it take to fully charge an electric car?

It all depends on your car's battery capacity. A Tesla Model 3 has a battery capacity of 50 kilowatt-hours (kWh), which means it takes 50kWh to charge the car from 0% to 100%. The models available through our EV Subscription take between 40-70kWh to achieve a full charge.

Compared to home appliances (one charge):

50kWh could:

  • Run a 100W lightbulb for 21 days
  • Run an oven for 25 hours

Compared to home appliances (annual consumption):


Compared to petrol:

The average petrol passenger vehicle

The 2017-2023 Tesla Model 3

  • Energy uage: 14.4 kW/100km 
  • Energy price (estimate): $0.25kW
  • Cost per 100km: $3.60 

Calculating cost:

To calculate how much it will cost to fully charge your EV, simply multiply your electricity rate by the size of your EV battery. Here’s the formula:

EV battery size (kWh) x Electricity rate ($ per kWh) = Total charging cost ($)
