Quick math tells me gas is cheaper than public electric chargers?

Recommended Posts

I'm currently researching whether or not I should buy an EV.  I'm currently considering the Hyundai Kona Electric.

A Better Route Planner was extremely helpful in looking into the implications of long distance travel.  I checked the route from Louisville, Kentucky to Dallas, Texas.

Waiting for charges would extend a traditionally 12.5 hour trip to 17.5 hours--a trip longer by 40%, or 5 hours.  At 30mpg and $2 per gallon, this trip would cost $55.73 with a gas vehicle.  This all begs the question: how much is your time (5 hours of waiting) really worth?  If you ignore charging costs, waiting 5 hours to save $55.73 would "earn" you just $11.15 per hour (decent pay for just twiddling your thumbs, but still not great).

But the real kicker is this: these electric charges are not free.  Every stop along the way is at Electrify America, who charges $1 per session and 35¢ per minute.  That would total to $80.10 for a very long electric road trip, versus a much quicker gas trip totaling $55.73.

Were my assumptions preposterous, or is this the reality of long-distance travel in a Hyundai Kona Electric?

I charged my Chevy Bolt once at Electrify America to “baseline” planning for a 650 mile trip. My average cost per kilowatt was $0.70 with a charge rate of 34.5 kWh in 60 minutes of charging. At home, where I charge 95% or more my rate is $0.12-$0.10 per kWh. On the other hand, there is a ChargePoint DCFC 20 miles north of the EA Charger were I pull the same charge for about $7

Absolutely depends on who you charge with.  EA is very much priced assuming faster charging (Like all the Audis / VWs / Porsches that are coming to market in the near future that charge at 120kW+).  It's specifically designed to disincentivize people with current-gen <50kW charging cars from hogging a stall for hours at a time when they don't have to.  Kona Electric is still a pretty slow charging car, even though it can hit 70kW or so:

Other charge networks are quite a lot more reasonable price-wise.  I charged pretty much exclusively with EVGo on a recent road trip in a Bolt EV.  I made one stop at an EA station, which was admittedly fairly expensive, but I didn't take much charge (only what I absolutely had to).  The rest of the ~1000 mile trip was with EVGo and free destination charging at hotels / family homes etc, and it only cost me $41.  Compared to making the same trip in a 40mpg car in a similar class (which is optimistic), that would use ~25 gallons of gas, and even at Texas prices, would cost around $50.

It really depends who you charge with.

To work around that, since we don't have costs implemented for these networks yet, I would suggest finding the cheaper networks you're seeing around you and click on one of their chargers on the map.  If you select "Prefer {this network} Chargers" we'll try to use those chargers more than others when possible.

One other component you commented on is the extra time.

I can only speak for myself, but with two adults and 3 boys in the car a Bio Break, takes a minimum of 30 minutes, and with decisions over snacks etc. can easily take 45 min.  We are probably slower than average, and certainly if it is just me on a long hard drive, I take much faster breaks, but... wit the EV you do these things while you charge, vs the ICE process of take care of the people, then take care of the car.

Depending on your situation, the "extra" time to charge is not nearly as bad as it seems.

If you time for the trip already included these stops, then some of the charge time will just be those breaks.  If the time was just pure drive time, then you would need to add some time for gas and Bio anyway, so again the charge time is not as bad as it first appears.

AS for the price, well see the other posts, but even at the EA chargers you still need to consider you mix of long high way trips vs. urban driving.

If you are buying an EV for primarily long distance trips you might want to be looking to spend the cash on a Tesla.... Just saying.

But if it is mostly for commuting with the occasional LD trip, well even at EA rates you will be saving vs. ICE (over the year)

 

Cheers,
