Remember that the reason a supercharger takes an hour to charge is due to the limits of battery chemistry. If you quadruple the size of a battery, it will still take only an hour to charge. Presumably Tesla has a super-duper charger in mind which will be able to charge a truck in an hour just like normal super chargers can charge several vehicles simultaneously. Creating a high voltage/amperage charging system would be easier than swapping batteries. Truckers often prefer driving many hours at a time, but most would be willing to pay more for a rig that needs to stop every 4-5 hours to recharge the truck if the fuel costs are much lower. Owner-operators can only drive around 13 hours a day anyway. Maintenance costs should also be lower. Electric trucks should win a few years after you can find super-duper chargers everywhere. I look forward to the day we never have to hear another Jake brake.
