Charging infrastructure at rest areas for battery long-haul trucks

For the market ramp-up of battery electric trucks, the public infrastructure construction is one of the most important elements and the installation must take place timely. In the future, break and rest periods at rest areas will be used to charge the vehicle battery of long-haul trucks. In order to identify the site-specific charging and energy demands at rest areas, a load modelling approach was developed and transferred into a simulation model that is based on the parking behaviour of long-haul truck traffic. The focus of the approach is the transferability to other sites. The forecast for site-specific parking occupancy is based on a combination of dynamic parking data and counting point data on road utilisation and is supplemented by the derivation of parking behaviour from synthetic trip chains. Depending on the duration of the break or rest period, a charging strategy is assigned to the arriving battery electric truck, megawatt charging for intermediate charging during short breaks and combined charging system for overnight charging during longer rest. As a result, the load modelling approach provides forecasts of site-specific parking occupancy, energy demand and charging profiles of battery electric trucks.
