Electric bus

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.

Load profile

The current or power a battery must deliver as a function of time in its application — a drive cycle for a car, a daily charge–discharge pattern for storage. Aging tests built on a realistic profile predict life better than constant-current cycling.

Range

How far an electric vehicle travels on a full charge: usable energy divided by consumption per kilometre. Cold weather, speed and heating cut it, and the gap between official and real range is usually consumption, not battery capacity.

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.
