Summary: Researchers at Chalmers have found that heavy goods trucks powered by electricity can be cheaper to run than diesel trucks. The study was inspired by a real haulage company that runs fixed routes between Helsingborg and Stockholm. The researchers compared two battery sizes with two scenarios for the price of fast charging and found that the smaller battery is the most cost-effective, provided that the price of public fast charging is low. The advantage of the smaller battery is that it can carry heavier loads, while the advantage of the larger battery is that it can charge more cheaply in the company's own depots. The study concludes that driving heavy electric goods trucks can still be cheaper than diesel goods trucks if driven in the right way.
