So has anyone done the math on what the EVGo charging prices translate to in comparison to traditional MPG cost?
Living in Illinois and a north Chicago suburb, public EV spots are few and far between but we charge exclusively at home. We have done a comparison to our current ICE car which at the time (before the extreme cost) was granting us about 26mpg.
So we did a fun little test.
After driving 80 miles, our Spark EV costs us about $2 in electricity to recharge.
After driving 80 miles in our ICE car, it cost us $7.50 to refuel.
So how does the EVGo public station price compare?
Every Friday I drive on the freeway from my home in Manteca, CA to Oakland, CA. The round trip mileage is 134 miles and I stop at an EVgo DCFC station in Pleasanton, CA going and at another EVgo DCFC station in Livermore, CA returning. The weather yesterday was in the low 50s in the afternoon when I left and in the low to mid 40s in the late evening when I returned. I used 8.64 kWh [17 minutes / $1.70] from home to the EVgo station in Pleasanton and 12.3 kWh [18 minutes / $1.80] from Pleasanton to my destination and back to the EVgo station in Livermore. I charged to 95% at both locations.
My current EVgo subscription [ $14.95 / mo + $0.10 per kwh] extends through May 2020 at which time it will go up to $19.95 / mo + $0.20 per kWh. Without going through all of the math, here are my cost estimates based on 4 trips [8 charging sessions] per month @ 4.5 mi / kWh [winter]:
Current EVgo subscription: $0.077 per mile or $0.35 per kWh
New EVgo subscription: $0.127 per mile or $0.57 per kWh.
My electric charging cost at home, including charging losses, is $0.053 per mile or $0.24 per kWh.
You reported you drove the ICE 80 miles at a cost of $7.50. This equals $0.094 per mile.
My EVgo subscription is my ticket to venturing out beyond the single-charge range of my Spark EV. I call it "travel insurance". I almost exclusively use EVgo but I also have accounts with ChargePoint and Greenlots.
