78 kWh is approx 5 charge cycles. If you have 100ish miles on electric showing, then youre not far off 22 miles of range per charge.
When looking at your electric rates, are you combining the generation and the delivery rates? $.06 per kWh is very, very cheap.
Also, ignore the mpg read out in the dash. It’s useless and inaccurate. Unless you have actually divided miles traveled by the gas you put in, you dont have any useful information as to what mpg you’ve been getting.
