I'm not saying BEV long haul trucks are practical right now, but those electricity costs look too high. US Commercial electricity rates are half that. Industrial and transportation electricity rates are even lower. Lower fuel costs is one of the main benefits of electricity vs diesel(Although whether or not they can offset higher capital costs is another question.)vtsnowedin wrote:So P is going to replace 115 gallons of diesel per day with a battery containing 1800 KWHs of electricity? Lets say we can buy the diesel for $2.50 a gallon. That's $287.50 a day which is not cheap if it is coming out of your own pocket. But what does it cost to charge the battery pack. No figures given on the efficiency of charging units but we can presume it is not 100% and it certainly is not free if bought in that large a chunk. So let's guesstimate that commercial electricity through a high speed overnight charger costs a net of $0.20/KWH after efficiency losses are factored in.
1800 X 0.20= $360.00 per day.
Maybe when diesel gets to $10.00 a gallon companies will buy fleets of electric heavy trucks but not now.

These results clearly show that a high utilization of the E-Truck is needed in order to make a compelling business case. By “high” utilization we mean a daily mileage greater than 50 miles. At these high daily utilization rates, a sufficient amount of diesel fuel is displaced by cheaper electricity to make the investment into higher upfront costs E-Trucks worthwhile. However, at lower daily utilization rates (lower than 50 miles), fuel and maintenance savings will not pay for the higher incremental cost that E-Trucks typically show.

Here's a business case for BEVs vs diesel trucks that had a similar conclusion. Although this study is for short delivery and not long haul, the area I am interested in here is the fuel cost analysis:BATTERY ELECTRIC PARCEL DELIVERY TRUCK TESTING AND DEMONSTRATIONTable 6-7: E-Truck fuel cost
