7 seconds to be precise: << battery powered UPS delivery vans in cities makes the most sense. They go back to the same place all the time and they could change out the batteries and put the vans back on the street pretty quickly. >> Eric isn't much on economics. UPS can do arithmetic though, so they can compare the cost of bigger heavier vans with 1 ton batteries that take half an hour to get a part charge, and smaller lighter vans with 100 kg 7SSS batteries that are back on the route in 7 seconds instead of half an hour. UPS can also understand that the running cost of a van with an extra ton of battery is more than one that is NOT carrying those extra hundreds of kilograms. When moving freight around, weight matters. Road designers limit maximum weights because roads are also sensitive to the tons passing by. UPS does not want to buy more electricity than they have to do to deliver a parcel. They want low operating costs. Less weight = less cost to push it along the road. It also means less cost to support it = smaller tyres, lighter wheels, smaller electric motors that also mean less weight which means less tyre and wheel and suspension weight and less body mass needed. With less vehicle weight, iEric thinks of electric cars as a fun thing to swoop around in doing virtue signalling. Regular humans see them as a better way to get things done cheaper. To Eric, who has big piles of money, spending it is for fun. So a Tesla money burner is fun. Elon Musk thanked the early Tesla buyers for funding the development of what he really wants to do. UPS on the other hand does NOT see spending money as fun. They spend only as much as they have to do to get the job done. If they can deliver a parcel with less electricity needed, they'll do it if other aspects of the business are not harmed. If they can use less electricity AND save on battery cost, AND save on time recharging [half an hour], AND save on vehicle cost, AND save on peak electricity prices by batteries being recharged when the sun's out and lower electricity prices are available, then they will do it. They won't choose the big heavy expensive van with a huge battery that requires an hour in a recharging queue. Mqurice
