Question: how much electricity does it take to charge a tesla at home?
Answer: And at home is where most Tesla owners do their charging. In January, Tesla announced that it was raising the charges for electricity at its Superchargers by 20 per cent, from 35c per kWh to 42c per kWh. This means it now costs $5.25 more to fully charge a Model S with a 75kWh battery, at $31.50.
