To advance the use of battery electric drives and especially megawatt charging for heavy commercial vehicles, high-performance charging points are indispensable.

A new collaborative re­search proj­ect on the topic of electric heavy goods transport was launched at the end of Sep­tem­ber with a total of 13 partners from industry and re­search. Under the title “High-Per­for­mance Charging for Long-distance Trucks” (HoLa), two high-performance charging points will be set up at each of four sites and operated as well as tested in real logistics operations. Pro­fes­sor Christian Rehtanz and his team at TU Dort­mund Uni­ver­sity are responsible for the accompanying re­search.

“After electric cars, in the interest of climate protection we now have to tackle heavy goods transport and show that this can also function well with electricity,” says Pro­fes­sor Christian Rehtanz, explaining the task that the con­sor­tium will be tackling from now on. This development requires a massive expansion of infra­structure, especially in the area of megawatt charging. The HoLa proj­ect aims to contribute the necessary know-how by building and operating prototype high-performance charging points for trucks. It is one of three innovation clusters for climate-friendly truck drive technologies launched by the Federal Ministry of Transport and Digital Infrastructure (BMVI).

High-performance charging points are indispensable

To advance the use of battery electric drives and especially megawatt charging for heavy commercial vehicles, high-performance charging points are indispensable. Currently, however, there are still a lot of unanswered questions and above all a lack of experience in the setting up and operation of such charging points. This is precisely where HoLa comes in: Under the aegis of the German Association of the Automotive Industry (VDA) and led by the Fraun­ho­fer In­sti­tute for Sys­tems and In­no­va­ti­on Research ISI, the con­sor­tium will set up and operate a total of eight high-performance charging points at four sites.

First of all, CCS (Combined Charging System) charging points will be planned and put into practice in a first phase, followed by high-performance charging points using MCS (Megawatt Charging System) technology.

The sites are located along the A2 highway between the Ruhr region and Berlin – in addition to highway rest areas, they also include logistics centers so that different applications can be taken into consideration.

In the frame­work of the proj­ect, the In­sti­tute for Energy Sys­tems, Energy Efficiency and Energy Economics (ie3) at TU Dort­mund Uni­ver­sity, headed by Pro­fes­sor Christian Rehtanz, is dealing with the integration of high-performance charging infra­structure into the electrical energy system and especially into power grids. They are examining whether grid connection is possible at the demonstration sites, but also across the whole of Germany, and which technical and economic aspects need to be considered.

Partners from industry and re­search

The proj­ect has an overall budget of € 27 million, funding of € 12 million and will run until the end of 2024. A total of 13 partners from industry and re­search are involved: Fraun­ho­fer ISI is con­sor­tium leader, and P3 Automotive GmbH is responsible for proj­ect management. Other partners are EnBW mobility+ as operators of the charging stations as well as charging infra­structure suppliers ABB, Heliox and Siemens. Daimler Truck, TRATON, MAN, Scania and Volvo are responsible for the vehicles. In addition to Fraun­ho­fer ISI and TU Dort­mund Uni­ver­sity, the Fraun­ho­fer In­sti­tute for Industrial Engineering IAO, the Uni­ver­sity of Stuttgart, Bauhaus-Uni­ver­si­tät Weimar and TU Berlin are accompanying the demonstration proj­ect.

Location & approach

The campus of TU Dort­mund Uni­ver­sity is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dort­mund-Eichlinghofen” (closer to South Cam­pus), and from B 1 / A 40 “Dort­mund-Dorstfeld” (closer to North Cam­pus). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from North Cam­pus to South Cam­pus by car, there is the connection via Vo­gel­pothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Cam­pus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

TU Dort­mund Uni­ver­sity has its own train station (“Dort­mund Uni­ver­si­tät”). From there, suburban trains (S-Bahn) leave for Dort­mund main station (“Dort­mund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 15 or 30 minutes). The uni­ver­si­ty is easily reached from Bo­chum, Essen, Mülheim an der Ruhr and Duis­burg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dort­mund Uni­ver­sity leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop “Dort­mund Kampstraße”. From there, take U43 or U44 to the stop “Dort­mund Wittener Straße”. Switch to bus line 447 and get off at “Dort­mund Uni­ver­si­tät S”.

The AirportExpress is a fast and convenient means of transport from Dort­mund Airport (DTM) to Dort­mund Central Station, taking you there in little more than 20 minutes. From Dort­mund Central Station, you can continue to the uni­ver­si­ty campus by interurban railway (S-Bahn). A larger range of in­ter­na­tio­nal flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the uni­ver­si­ty station.

The H-Bahn is one of the hallmarks of TU Dort­mund Uni­ver­sity. There are two stations on North Cam­pus. One (“Dort­mund Uni­ver­si­tät S”) is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Cam­pus) Eichlinghofen. The other station is located at the dining hall at North Cam­pus and offers a direct connection to South Cam­pus every five minutes.

The facilities of TU Dort­mund Uni­ver­sity are spread over two campuses, the larger Cam­pus North and the smaller Cam­pus South. Additionally, some areas of the uni­ver­si­ty are located in the adjacent “Technologiepark”.
