摘要：

The transport sector is responsible for 20 % of the global CO2 emissions. By transitioning from internal-combustion engine to battery-electric vehicles, there is a big potential in reducing the emissions. 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 to deliver the charging power needed. In this paper, a methodology to model the load profile of a high-power charging station for HDEVs is proposed. Generated load profiles with different future shares of HDEVs are used to study the impact on the power grid in a representative area in Norway. The loading of the regional substation exceeds its rated capacity when the share of HDEV is 25%, and its thermal limit when the share is increased to 50%. Extending the mandatory breaks for the drivers, and a corresponding reduction of the charging power, shows promising results.
