Interim assessment of the practical use of electric trucks:
As part of this project, five e-trucks are on the road. Further three e-trucks are also operated by CNL member companies, which are not part of the project consortium.
In total, almost 250 tons of greenhouse gas emissions have already been saved compared to operating these vehicles as diesel trucks.
The graphic below shows the total savings in greenhouse gas emissions from operating all CNL electric trucks since the project started in October 2018 to January 2020.
Within the practical use of the electric trucks, in addition to the technical parameters, the suitability for the respective logistical applications is recorded. The feedback from the dispatchers and logistics planners as well as the truck drivers are essential. The most important statements and findings are presented below.
Economic prospects and opportunities for e-trucks:
Of course, the cost situation of the required components plays a decisive role in establishing electric trucks in transport logistics. As part of the project, the cost development of the most important technical components for future e-logistics will be continuously evaluated and forecasts adjusted and refined:
- Battery systems
- Electric trucks
- Charging infrastructure
The following graphic shows a forecast of the cost development of charging infrastructure with different charging capacities in the period 2020-2030.
The development of costs for battery systems also plays a crucial role. A cost forecast including fluctuation ranges up to 2050 can be seen in the figure below.
The most important and largest cost factor is of course the electric truck itself. The following graphic shows two scenarios for the cost development for electric trucks with a battery storage capacity of 200kWh by 2030.
Preliminary interim results:
Two essential parameters have a significant impact on the implementation or conversion to electric truck fleets.
- The required energy and power consumption at the charging locations and the required technical framework
- The total cost (TCO - Total Cost of Ownership) of possible electric truck fleets
The following figure shows an exemplary load profile of an investigated logistics HUB. The current power and energy consumption is shown in green. The yellow lines show the power and energy consumption through a 100% conversion of the existing fleet to electric trucks. It was shown here that over 98% of the charging energy could be charged at the HUB.
Finally, the resulting power and energy consumption for this exemplary HUB is shown in gray.
Based on initial simulation results, a preliminary TCO comparison between diesel trucks and electric trucks was determined. The following figure shows the TCO parity between diesel and electric trucks depending on the year of purchase. Each point stands for a truck - the different colours for the respective years of purchase. For points below the blue cost parity line, it would be cheaper to buy a new electric truck than a diesel truck.
Further optimizations as part of the MEGAWATT project are intended to help further reduce the planning costs in order to make the use of electric trucks economically interesting on a large scale in just a few years.
