I did some calculations.
I used $2.25 a gallon for gasoline.
$0.15 a kilowatt hour for electricity.
From the article 687 wh/mi for one leg of the trip while towing.
Divide the 2.25 by the .15 to get a gallon of gas equate to to kWh.
I got about 15 kWh.
Divide the 15 kWh by the 687 wh/mi I got about 22.
Thus the mi/ gallon of gas equivalent is about 22 mpg.
The best that the article mentioned was 500 wh/mi without the trailer.
Thus about 30 mpg gas equivalent.
Yah I don't know. Might be something off there. Using our own real life numbers for our vehicle it takes about 3.30 to fill our battery from almost dead. (We pay 11 cents per KWH) We go about 180 to 200 km on that depending on what kind of driving we are doing. I haven't figured that out in mileage but its a lot cheaper than the old days when we were using gas or diesel. I would imagine towing would be pretty hard on power consumption though. Then again, towing is pretty hard on mileage too though.
I found it interesting where one of the challenges EV drivers pulling trailers are facing is finding pull through fast chargers. I can attest to this as most I have seen are not in easy to access places while towing something. Some are in bigger parking lots like this.
But many are in spots like this which would be tricky with a trailer. Thats Angela beside her leaf.
I suppose there will be an evolution of DC fast charger accessibility as well. I think using the service station approach or even old service stations as they are in some European countries would work. It will be interesting to see how this evolves over the next couple decades.
