Daniel Hamilton comments on the charging cost of Tesla Model 3 vs Chevy Volt in the GM Electric Vehicle Owners group on Facebook.

I have owned and driven both a Volt AND a Model 3. Here is how much it costs to charge an electric car at home and at a public station.

My lifetime average is 4.5 miles per kWh in the Model 3. Here in Illinois the Supercharger rates are $0.24/kWh.

Assuming I charge the Model 3 at home at a price of $0.13 per kWh before leaving on a "long trip", that works out to $0.029 per mile for the first 210 miles followed by $0.053 per mile for the remaining miles.

I tracked my average as 4.2 miles per kWh in the Chevy Volt, and then I got 41 MPG on the gasoline engine after that.

Premium gasoline in Illinois is currently approximately $3.399 per gallon.

Assuming I charge the Volt at home at a price of $0.13 per kWh before leaving on a "long trip", that works out to $0.031 for the first 53 miles followed by $0.083 per mile for the remaining miles.

Lets look at a 1000 mile trip:

Telsa Model 3: $6.09 for the first 210 miles plus $41.87 for the remaining 790 miles = $47.96.

Chevy Volt: $1.64 for the first 53 miles plus $78.60 for the remaining 947 miles = $80.24.

That's an extra $32.28 in the Chevy Volt.

Which vehicle will bite your wallet if you decide to take a long distance trip with it and have to use commercial stations?
