Electricity Cheaper Than Diesel for Heavy Goods Vehicles

The transition from a fossil-fuelled to an electric vehicle fleet has so far been most visible in lighter vehicles, such as private cars and delivery vans. In the case of heavy goods vehicles (HGVs) travelling long distances, the transition has been slow because the prevailing view is that such vehicles would need large batteries, which take up so much load capacity that electric operation is not profitable. But now researchers at Chalmers University of Technology have found that electricity can indeed be a cheaper alternative to diesel - even for heavy goods vehicles.
"We have looked at a scenario where heavy goods vehicles drive the 553 kilometres between Helsingborg and Stockholm in Sweden. We have compared two different battery sizes and two possible prices for fast charging. Our conclusion is that it seems possible to electrify this type of vehicle in a cost-effective way," says Johannes Karlsson.
In the study, the researchers created a model based on data from a real haulage company in the town of Helsingborg, which was chosen because it can be considered to have typical tasks and operating conditions for a haulage company in that part of Sweden covering long distances. The large battery did not need to be recharged on the road, only at the company's own depots, but it did take up more load capacity. The smaller battery needed quick charging on the road but did not restrict the load capacity as much. The results showed that running on electricity was profitable for the haulage company in the study.
