I'm not going to dispute your numbers with diesel versus EV reliability, but I have to think the simplicity of an EV drivetrain will win that battle in the next version or two.
> The BEB fleet operated at 66% availability with more than half of the total days related to retrofit of the charger cabling and programming by the OEM.
I guess you could say this is due to immature technology but honestly I don't see 75% of HPC chargers being offline for maintenance at any given time. This is probably just bad luck with a vendor.
If you look at the road calls the BEB is by far the most reliable one, causing one road call out of 45. It was also the cheapest per mile by a long stretch.
Certainly wind power was viable as soon as fiberglass was invented.
The mass engineering should have also been directed at that which would have saved us a billion tons of carbon.
Or more precisely put, batteries are a sort of black box they ether work or they don't work but either way you are not going to be able to open one up and find out why. that is, they are a high cost unrepairable item on the vehicle and this is a huge liability.
So a battery pack should actually be heavily redundant ... assuming the pack has enough modules for a loss of vehicle to get to some charging station.
