[M3WC]

This isn't rocket science. Using Model 3 SR(LFP) for example.

60kwh battery pack size(nominal). We will ignore the actual usable kwh, for sake of easy math. Lets say your utility charges $0.10/kwh. That is $6 to charge to 100% from 0%.

Using a conservative avg range per full charge of 200miles(city/highway combined). $30 for every 1,000 miles. This will also very due to climate.

It all comes down to what your utility charges. Some have lower rates at night, rather that peak hours.
