The influence of electricity storage on the economic viability of truck charging infrastructure: an investigation into the challenges and opportunities

The electrification of the mobility sector, particularly in the truck segment, requires a comprehensive charging infrastructure. Significant challenges remain in implementing a nationwide charging network. Key obstacles include the high costs and long implementation times associated with medium- or high-voltage grid connections, compared to low-voltage alternatives. Integrating electricity storage systems can alleviate these challenges by enabling grid connections at lower levels, either temporarily or long-term, thus improving the overall system's economic efficiency. A lower grid connection level can reduce investment and operating costs, lowering grid usage fees by reducing peak loads. Additionally, electricity costs can be minimized by purchasing power during periods of lower prices, and participating in the electricity market can generate additional income. This article examines how electricity storage systems affect the economic feasibility of truck charging infrastructure, focusing on various business models through a case study in Germany. It considers factors like price-controlled charging, storage size, grid connection, and energy demands. The findings provide insights into how storage systems can enhance the economic viability of high-power charging infrastructure.
