Charging infrastructure is “one of the largest unknowns and sources of anxiety for fleets considering near-term adoption of this technology,” according to a May, 2019, report the North American Council on Freight Efficiency.
Battery technology, too, still has a way to go before long-distance heavy hauling is reliable, affordable but – perhaps most importantly – light enough. A 2017 study by Carnegie Mellon University found that a battery powerful enough to drive a Class 8 semi-truck (i.e. a truck capable of hauling 18,000 kilograms, or 40 tons) over a distance of 1,000 kilometres would require a battery that weighs more than the cargo. That puts these vehicles at a distinct disadvantage compared with internal combustion engines (ICE), and it will likely remain that way for years, auto analyst Dennis DesRosiers said.
