Copenhagen Way Ahead Of Official Plans — Electric Buses To Enter Operation 6 Years Early | CleanTechnica
Now those zero-emission new buses will start being put into operation 6 years earlier, and that is actually amazing. It’s not unusual for tests like these to go on for years and years, but I suspect this has a lot to do with the fact that if you replace an old worn out bus with a new diesel bus, it would not make sense to have it in operation for less than 10 years or so, and that is simply to long.
In comparison to diesel buses, it’s reasonable to assume that electric buses are far simpler to service, because the drivetrains are expected to last much longer. Battery lifetimes do not seem to be much to worry about, and why should they? In the worst case, batteries are much easier to replace than worn out internal combustion based drivetrains.
