Lithium Ion battery costs have improved tremendously over the past few decades, but energy density has not improved at nearly the same rate. Energy density is the primary problem with electric trucking, because it significantly reduces the payload a truck can provide for a given range. I would be skeptical of electric heavy trucks without a real breakthrough in energy density.
