This doesn't always make sense. In Zürich Switzerland the calculation was done between placing charging systems at end terminals or at the central garage (where busses park over night). It was determined that a central garage charging setup is better because the time the bus spends at the end station may get shortened significantly in order to keep the bus on schedule. So charging time would be very irregular. Also to get the power infrastructure to those locations is very costly compared to a central location. The new battery bus fleet in Zürich can run for about half a day and then return to the central garage. Future buses are expected to become more efficient and have larger batteries so the central charging setup makes sense. The central garage has a fast charging setup for 74 busses underground. It is a very impressive setup.
