Challenge and objective

  • The upcoming heavy-duty electric vehicles (HDEVs) are expected to have a charging power between 100-1600 kW.
  • A transition to HDEVs can cause challenges to the power grid.
  • We aim to create load profiles of a high-power charging station for HDEVs in power flow analysis.

Work performed

  • Developed load model for HDEVs.
  • Constructed a case study for a relevant Norwegian areas.
  • Evaluated impacts on increasing mandatory breaks for HDEV drivers.

Significant results

  • HDEV charging causes overloading issues when share of EVs is in the range 25-50 %.
  • Increasing mandatory breaks for HDEV drivers reduces charging peaks significantly.

Impact for distribution system innovation

  • Crucial to understand the grid impact of new types of EVs with very with power demands.
