The EPA has done this work for you. The car is rated at 79 MPGe.My ChargePoint arrived in the mail yesterday (7/26/2021). Looking forward to getting it installed which should be by the end of the week. The slow Level 1 charging is starting to become a bit of a negative, so I’m excited to be able to charge it to 90% faster. I want to primarily charge at home.
I did get two electric bills since purchasing the car, and even though I have solar panels, I was surprised at how much the increase was since I haven’t been charging it every night. My bill was over double what it usually is. 😕 How has everyone else’s electric bills been?
Determine the cost of a gallon of gas. If it is currently about 4 dollars per gallon, the electric cost of going 79 miles will be about 4 gallons.
This is not an exact calculation as there are many variable in arriving at this calculation. It doesn't include different gas and electric pricing variable,. But is is an easy number to obtain. It is based on national averages.
Other than that, go to your electric bill and find out the cost per kilowatt hour. Then, how many miles you drive and the average kilowatt usage.. .
Since EV charging demands a high electric flow, your solar setup may not equipped for full solar charging, thus the added costs.
Without knowing your typical bill, double the cost is an unknown amount.
