eHighway – Electrification of road freight transport

Road freight transport powered by electricity: Siemens’ eHighway system combines the efficiency of electrified railroads with the flexibility of trucks into an innovative freight traffic solution that is efficient, economical, and environmentally friendly.

eHighway

Reduce truck operating costs and emissions

Implementing eHighway on the core highways creates a backbone solution for energy efficient, low cost, zero emission trucking that is complementary with other drive trains, fuels and transportation technology trends (e.g. automated or high-capacity vehicles). The eHighway system is applicable for various use cases.
Siemens’ eHighway: a contribution to a transport sector independent of fossil fuels.
eHighway for high frequency shuttle transport

Shuttle transport

Heavily-used truck routes, for example from ports to freight and distribution centres, are often a burden on the environment. In these situations, the eHighway system produces a significant reduction in pollutant and CO2 emissions. At the same time, the economic benefits of the system are felt particularly quickly on these high-use routes.

  • Solution for high frequency shuttle transport over short and medium distances (< 50 km), i.e. in ports or industrial areas
  • Lower fuel consumption and longer lifetime
  • Reduction of air and noise pollution
eHighway for electrified mine transport

Electrified freight transport in mines

The eHighway is an ideal way to connect pits and mines with warehouses, transshipment points or processing plants. The economic benefits of the eHighway system can be easily calculated on the basis of transport volumes. At the same time, the eHighway system significantly reduces environmental pollution and dependence on fossil fuels.

  • Connection of pits and mines to storage or transit locations
  • Minimization of harmful emissions
  • Sustainable, clean and economical mine operation
eHighway for electrified long-haul traffic

Electrified long-haul traffic

The eHighway system is based on a safe and proven infrastructure to provide a continuous energy supply to heavy commercial vehicles. It can be integrated and operated within the existing road infrastructure without significant effort and combines the efficiency of electrified railroads with the flexibility of trucks, halving energy consumption while maintaining full mobility. The eHighway system enables trucks to use renewable energy and can contribute significantly to reducing CO2 emissions. Both the ecological and economic advantages of the eHighway system grow with increased use of the route.

  • Economical and sustainable alternative for road freight transport
  • Significant reduction of CO2 emissions
  • Substantial cost savings for freight carriers

How eHighway works

Energy supply

The energy supply system is based on proven technology from the world of railroad electrification. The two-pole catenary system ensures a reliable energy supply for the eHighway truck. The catenary system leads to a level contact wire that enables stable current transmission, even at high speeds. The overhead contact lines are supplied with energy from substations equipped with:

  • Medium voltage switchgear
  • Power transformers
  • Rectifiers

Controlled inverters (for feedback of the electric energy generated by the vehicles’ regenerative braking).

Pantograph

The active pantograph transmits the energy from the overhead contact lines to the electric motor of the eHighway truck. The pantograph can be easily connected to and disconnected from the contact wire at speeds  ranging from 0 to 90 km/h. This is done either automatically or manually at the push of a button. Steering an eHighway truck connected to the overhead contact lines is no different to driving a diesel truck, as the active pantograph compensates for any shifts in position within the lane. The pantograph automatically disconnects in the event of evasive maneuvers or if the  indicators are used.

Hybrid drive

On electrified routes, the electric motors in eHighway trucks are powered via the overhead contact lines and the active pantograph. For remaining sections of road, the eHighway truck has a hybrid drive. There are no restrictions on the type of hybrid drive: depending on the application and customer requirements, serial and parallel concepts with internal combustion engines, battery solutions, fuel cells etc. can all be implemented. The electric motors of the eHighway trucks also enable recovery of the vehicle’s braking energy.

First eHighway in Germany

  • Installation of an overhead contact line system for electrified freight transport on a ten-kilometer stretch of autobahn for the customer Hessen Mobil
  • eHighway is built on the public A5 federal autobahn between Weiterstadt and Langen/Mörfelden
  • Field testing of the eHighway system up to 2022, together with research partner TU Darmstadt and provider entega
  • Scania supplying five overhead line hybrid trucks for this project, with a total of 15 being provided for German field testing
