VDV 238
The VDV recommendation on measuring the energy consumption of buses, including electric ones, by defined drive cycles. Together with the UITP SORT cycles it is how a tender states and checks the consumption, and therefore the range, of an electric bus.

Example
Vehicle and transport standards: an example situation
Shipping tests and vehicle battery approval tests address different uses; passing one does not automatically satisfy another.
Read VDV 238 alongside Electric bus in this context. A battery-electric city or coach bus, with packs of 300–700 kWh on the roof and at the rear, LFP or NMC, charged overnight in the depot or at the terminus by pantograph. Its duty cycle — long hours, deep daily cycles, a twelve-year life — makes battery aging the central engineering question.
