Are Electric Delivery Vehicles cheaper to run than Diesel?

Previously, electrifying long-haul cargo-carrying trucks was deemed financially unviable. However, recent findings from Swedish researchers at Chalmers University of Technology demonstrate that operating electric heavy goods vehicles can be more cost-effective than using diesel.

Johannes Karlsson, a Doctoral student in Automatic Control Engineering at Chalmers, expresses his own astonishment at the outcomes and expresses optimism that additional transport companies and manufacturers of heavy goods vehicles will be encouraged to invest in electrification. This follows the demonstration of its cost-effectiveness.

The shift from fossil fuel-powered to electric vehicle fleets has primarily been noticeable in lighter vehicles like private cars and delivery vans. However, the adoption of electric technology in long-distance heavy goods vehicles (HGVs) has been sluggish due to the belief that these vehicles would require bulky batteries, compromising load capacity and rendering electric operation unprofitable. Nevertheless, Chalmers University of Technology researchers have now discovered that electricity can serve as a more economical alternative to diesel, even for heavy goods vehicles.

Johannes Karlsson reports on their examination of a specific scenario involving heavy goods vehicles traveling a distance of 553 kilometres between Helsingborg and Stockholm in Sweden. The study compared two distinct battery sizes and considered two potential prices for fast charging. Based on their findings, Karlsson states that it appears feasible to electrify this vehicle category in a financially efficient manner.

Study based on real-world data

In their study, the researchers developed a model utilizing data obtained from an actual haulage company located in Helsingborg. This choice was made due to the company’s representation of typical tasks and operational circumstances encountered by haulage companies in that particular region of Sweden, particularly when it comes to covering long distances. The larger battery employed in the study did not require roadside recharging; instead, it was replenished at the company’s own depots. However, it did occupy a greater portion of the load capacity. Conversely, the smaller battery necessitated quick charging during the journey but had a lesser impact on the load capacity. The study’s results indicated that the haulage company achieved profitability by utilizing electric power for its operations.

Johannes Karlsson highlights that by employing an appropriate battery size, it is feasible to electrify heavy goods vehicles in numerous instances, resulting in comparable or even lower costs than those associated with diesel-powered counterparts. The optimal battery size depends on the nature of the transported goods, whether they are light loads like parcels or vegetables, or heavy loads such as beverages or timber. Factors such as driving patterns and the cost of fast charging also play significant roles in determining the ideal battery size. Karlsson envisions a plausible future scenario wherein heavy goods vehicles will be equipped with varying battery sizes to accommodate these diverse considerations.

The investment required for batteries and charging equipment carries its own costs. However, previous research has demonstrated that in order to justify this investment, the battery of an electric heavy goods vehicle should be charged and discharged at least 1,400 times. It is worth noting that most commercial vehicles surpass this threshold over their operational lifespan, thereby validating the economic viability of the investment.

Hoping to accelerate transition

The studies conducted by Johannes Karlsson and his colleague Anders Grauers are regarded as exceptional in their field. Traditionally, investigations into the electrification of heavy goods vehicles have primarily focused on scenarios where the vehicles operate and charge within limited areas, such as harbours. The ground-breaking research conducted by the Chalmers University of Technology researchers now has the potential to expedite the shift from diesel-powered to electric heavy goods vehicle transportation. Their findings are anticipated to act as a catalyst for accelerating the adoption of electricity as a viable alternative in this sector.

Anders Grauers, an Associate Professor at the Department of Electrical Engineering at Chalmers, affirms that their research has successfully demonstrated the cost-effective electrification of heavy goods vehicle fleets. As a result, companies should be motivated to invest in this transition. Grauers further emphasizes that financial incentives typically facilitate rapid changes, and their study presents a realistic and applicable solution for numerous transportation operations.

More about the study:

The price of diesel was set at €1.20 per litre and the price of fast charging at €0.17 per kilowatt hour or, alternativley, €0.40 per kilowatt hour. The prices are stated excluding VAT. Otherwise, the researchers assumed that costs such as maintenance were the same for the HGVs regardless of whether they ran on electricity or diesel.

The model used in the study is based on data from a haulage company with realistic conditions and tasks. Although the researchers had assumed a low diesel price, the study concluded that it is profitable for a haulage company to electrify its fleet of HGVs, with the exception of vehicles that mostly load up to their maximum allowed weight.

The study, ‘Case Study of Cost-Effective Electrification of Long-Distance Line-Haul Trucks’, was published in the journal Energies and was written by Johannes Karlsson and Anders Grauers. The researchers work at Chalmers University of Technology.

The research was carried out in collaboration with the Swedish Transport Administration and Volvo Trucks and was financed by the Swedish Transport Administration.
