Question: how many kilowatt hours does it take to fully charge a tesla?
Answer: That will vary, depending on the state-of-charge of the battery when you go to charge it. But as a guide, Tesla batteries range from about 65 kWh to 100 kWh. To fully charge a dead-flat 100 kWh battery will take 100 kWh's of electricity (100 units on your utility bill).
