The E-Mobility Group of Daimler Trucks & Buses is launching a worldwide initiative to establish a charging infrastructure for battery-electric trucks. The initial focus is on charging stations installed at the depots of truck customers.
Within the framework of the initiative, the E-Mobility Group is bringing together the main players—e-truck customers, power grid operators, energy suppliers, charging hardware manufacturers and charging software providers—thus promoting shared infrastructure solutions for truck customers within the network.
The focus of activities is currently on the United States and Europe. Japan is the next market to follow. The first workshops have been taking place for some time now. The first joint pilot projects for setting up charging infrastructure at truck depots have also already been implemented or are in preparation.
The initiative is called “eTruck Charging Initiative” and is part of the E-Mobility Group’s holistic approach to provide truck customers with the best possible entry into e-mobility. The close dialog between the main players is also intended to speed up previously lengthy and complex planning and application processes for network connections. In addition, the participants are also concerned with aspects such as optimized load management of the electricity grid and sustainable electricity supply.
The sooner and more exactly the energy suppliers and power grid operators know what customers’ infrastructure requirements will be, the faster and more efficiently they can build them up. The initiative’s measures therefore include the development of standard concepts that cover common charging profiles. Different energy suppliers can use these concepts, significantly reducing their planning time. So far, infrastructure projects have mostly been treated as individual cases.
In addition, standardized and optimized forms accelerate the approval procedures for the network operators. Fast processes mean reduced costs for all involved. Other approaches, such as the best possible design of the interfaces between charging infrastructure, vehicle and grid, as well as the possibilities of controlling the grid load and thus ensuring the—as sustainable as possible—supply of electricity, are also addressed within the initiative.
In rural areas and when there is a high demand for electricity, it is also important to ensure charging reliability, which is another of the initiative’s subject areas.
From our point of view, depot charging at the truck customers’ depots represents the first and most important step towards entering the world of e-mobility. This means that the current fields of application for electric trucks in connection with urban distribution traffic can already be covered and the infrastructure can be ideally adapted to the logistics provider’s processes, resulting in the lowest possible charging costs. Depending on how the trucks are used, opportunity charging is also an option for extending their range, for example at the unloading or loading point where the electric trucks stop anyway. In the future, public charging at publicly accessible stations along central transport routes will also be an important aspect—a comprehensive charging infrastructure maximizes the operating range of battery-electric trucks.—Gesa Reimelt, Head of E-Mobility Group Daimler Trucks & Buses
In the case of depot charging, the infrastructure is individually tailored to the needs and processes of the respective logistics provider. The use of their own infrastructure usually offers advantages in terms of total cost of ownership (TCO), as no additional operator is involved. There is also no need for time-consuming billing and authentication of authorized vehicles, and a charging possibility can always be guaranteed. The charging procedures are subject to the company’s specifications and the energy costs can be calculated in advance.
Among other things, depot charging is suitable for applications with electric trucks in urban areas, which travel on routes that can be planned and which can be charged overnight or during regular downtimes. In most cases, there is therefore little or no change to the operating procedure. Battery-electric drive has the highest efficiency among the alternative drive systems, which is particularly useful in this application scenario due to the lowest energy costs. The development of further charging possibilities through opportunity charging and public charging will successively open up further applications with a larger radius of action for logistics companies.
Launched last year by the E-Mobility Group, the ecosystem for easy entry into e-mobility consists of three areas: Together with the customer, the key question is first clarified for which application profiles and routes electric trucks are already suitable today. For this purpose, the E-Mobility Group is rolling out the free “eTruck Ready” app, which uses existing driving routes to determine a realistic and meaningful usage profile of electric trucks for customers.
The charging processes of electric fleet vehicles are another key that must be integrated into the operating process. For this reason, a further focus of the consulting is on the analysis of the depots and the corresponding conception of the suitable infrastructure including intelligent charging solutions.
The third area deals with the optimization of the total cost of ownership (TCO). The experts of the E-Mobility Group will discuss, among other things, the possibilities of public funding for the infrastructure.
Since 2018, the E-Mobility Group has bundled Daimler Trucks & Buses’ global know-how in the field of e-mobility and now defines the strategy for electric components and products across brands and segments. As is the case with the global platform strategy for conventional vehicles, the E-Mobility Group develops an integrated electric architecture, maximizing the use of synergies and optimizing the application of investments.
At the same time, the E-Mobility Group offers comprehensive consulting for customers and focuses on the entire ecosystem with the goal to make e-mobility economically feasible also in terms of TCO. The E-Mobility Group is set up globally with employees working in various locations throughout the company's worldwide development network, i.e. in Portland (US), Stuttgart (Germany) and Kawasaki (Japan).
Global electric truck portfolio at Daimler Trucks. The heavy-duty electric truck Mercedes-Benz eActros with a range of around 200 km is being tested by customers in Germany and Switzerland as part of the eActros “innovation fleet”. The first customer handover took place in 2018, and series production is planned for the coming year.
In the US, the medium-duty Freightliner eM2 and the heavy-duty Freightliner eCascadia are also currently undergoing practical tests with customers—series production is planned for 2021 as well. As part of a small series, more than 150 electric FUSO eCanter light-duty trucks are already in use with numerous customers in Japan, the USA and Europe.
Daimler Trucks & Buses, one of the world’s largest commercial vehicle manufacturers, aims to offer only new vehicles that are CO2-neutral in driving operation (“tank-to-wheel”) in the triad markets of Europe, Japan and NAFTA by 2039. By 2022, Daimler Trucks & Buses plans to include series-produced vehicles with battery-electric drive in its vehicle portfolio in its main sales regions Europe, USA and Japan. In the second half of the decade, Daimler Trucks & Buses will extend its range of vehicles with hydrogen-powered series production vehicles.
