I'm curious how much range it gets before needing a charge, and how long it takes to charge during that break. Running 12 hours a day doesn't tell us anything about distance covered.
As for charging speed, this truck has 0.6 megawatt hour of battery on board. Mercedes used 600 kw chargers. So, that's about 1 hour. There are a few companies working on megawatt chargers for trucks, so that's a number that might come down.
More battery in the truck is possible but also more expensive. And at least in Europe breaks are mandatory every four and half hours anyway. So, the driver might as well plug in while they rest. The battery wouldn't be completely empty by then so it tops up faster.
So the implication is that it's not being used for that distance yet.
70km is really not very far. Great if you can take some short haul diesels off the road I guess, but that's not even a 1-hr drive on most roads.
But short haul and heavy duty like in a mine, this would be very handy.
Of course, they're also shuttering nuclear plants and reopening coal plants, so you might call it a step forward and a half-step backward...
