Since a truck hauling 20 tons of freight needs a lot of energy to move, it has to stop fairly frequently to charge; the T-pod can make it 124 miles before it has to plug in again. For other electric semis, charging time is a bigger deterrent, because it’s also wasting a driver’s time.

“If you have to stand still maybe one-third of the time to actually charge, that makes the business case for having a truck driver in a battery-powered truck not that good,” says Robert Falck, CEO of Einride, the Sweden-based startup making the T-pod. “But if you remove them and create a system where the truck driver drives it remotely and controls a fleet, you overcome that problem.”
