I have sometimes daydreamed of a "Push - Pull - Click - Click" (Eversharp Schick razor) concept. Truck pulls up, Robot attches on and removes the battery(s), indexes to the full pod and inserts the fully charged battery and off the truck goes.
Battery recharging is done off line at cheap rates. This does not eliminate any of the other excellent negative points you have outlined. If nothing else I suspect the weight of the batteries exceed the weight of the diesel engine it is replacing.
