The annual mileage of a vehicle can have a big impact on the TCO comparison between ICE and BEV.
As BEVs generally have a higher upfront cost but lower running cost than ICE vehicles, the amount of mileage the car makes can have a big impact on the TCO comparison. The following graphs show the TCO per mile based on the number of miles the vehicle runs per year. The higher the annual mileage, the lower the cost per mile for ICE and BEVs, but the BEV cost reduces more significantly. This means that at higher annual mileage, the BEV TCO can be lower than the ICE TCO.
In these graphs we have also included the costs for BEVs based on an average, off-peak, and public costs of charging. We would recommend a majority of depot-based charging to avoid the higher costs of public charging.
