The electrification of heavy-duty vehicles demands very high charging capacities, which in turn require large-scale grid connections. Securing such connections, especially those above 10 MW, typically involves long planning and construction times, creating a major bottleneck for the rapid deployment of public truck charging infrastructure. To address this challenge, intermediate solutions are needed that can accelerate the rollout while ensuring reliable charging operations. One promising approach is the combination of smaller, more readily available grid connections with stationary battery storage systems. By temporarily compensating for insufficient grid capacity, these systems could provide high-power charging services until a full grid connection is established. This contribution examines the technical and operational conditions under which battery storage can effectively serve as a bridging technology for heavy-duty vehicle charging infrastructure. Particular attention is given to the interplay between grid availability, charging demand profiles, and storage system sizing, with the aim of identifying scenarios in which such hybrid solutions offer both economic and practical benefits for stakeholders.
