Have other cities managed to work out how to prevent the need for electric vehicles to be recharged? If so, they should be sharing this useful information to other operators!
Wonder if they've worked out how to stop diesel buses needing fuel too .
I think you've taken
@Stan Drews' post completely out of context
There are many ways to allow for mid-day charging, without increasing the spare capacity drastically
One is the utilisation of peak buses (run-backs, if you're industry minded); for example a bus which would "traditionally" be in service from 06:00 to 08:30, sit spare in the depot all day, then come back out again at 15:30 until 19:00 is instead back out in service at 9am, allowing one of the first buses of the day to receive a charge boost. Once charged that then goes back into service, allowing a different vehicle to come off for charging, and so on, until all buses are required again in the afternoon peak.
Another alternative would be to graph bus allocations so that the last buses out [of the depot] are the last buses in, so to speak. Or, even more simply, have diesels stay out all night.
Increasing spare capacity drastically is like having money sat in the yard all day!
