About 15 years ago I rebuilt an old golf cart. What I learned was in the late 90's better motor controls lead to a resurgence of electric golf carts especially for fleets. In most use cases electric is better logistically. The electric ones just run and run and they don't require handling gasoline and oil. It's really quick for an employee to plug the golf carts in at night. Pain in the ass to run around with gas cans. Not to mention having to store fuel on site.
Reason conversion to electric happened earlier for golf carts was electric golf carts only have about 4-5kwh worth of batteries. Interestingly historically lead acid batteries are about $100-150 per kwr. Which is close to where automotive grade lion batteries are now.
So no surprise that delivery trucks are converting to electric. They have the exact some scenario going on.
A friend of mine runs a business servicing fork-lifts and similar vehicles. Mostly old propane or diesel powered fork lifts. When people ask him for recommendations about replacing a dead machine, he recommends they go electric due to reliability. It's a bit counter to his self-interests because they do require a fraction of the maintenance.
He also owns several electric golf-carts he's tunes up for speed and light 4WD.
When the Prius came out I looked at the drive train and it seemed obvious that the transmission on those things should and appears to be very reliable. It's a planetary gear set and two electric motors.
Fixed gears and electric motors life spans are between 25,000 and 50,000 hours. Vs less than 10,000 hours for a piston engine.
Everything about cars is designed around that fact that the engine is shot after 200-250,000 miles. Would not surprise me if eventually the expected life of an EV will end up being 2 to 3 times longer.
