D2.4 : Requirements and Specification of the Operational Fleet Management Support Tools

The Charging Energy Hub (CEH) project aims to accelerate the electrification of logistics transport by addressing financial, legal, and organizational barriers. The project integrates charging infrastructure, battery storage, and renewable energy into existing electricity networks, and the project use cases include both public and private charging locations. This report is part of Work Package (WP) 2 and outlines the requirements and interfaces for digital assets later developed in WP3. This report, Deliverable 2.4, defines the initial requirements and interfaces for two tools: the Fleet Planning Tool (FPT) and the Digital Twin of the Vehicle (DTV). These tools aim to predict and plan fleet charging activities, supporting flexible charging sessions and dynamic vehicle scheduling thereby attributing to CEH’s overarching objectives to provide more sustainable and cost-effective solutions to charge electric vehicles. The document serves as input for subsequent tasks in the project, including the development of: vehicle digital twins (T3.2), dynamic congestion-aware charger control (T3.3) and AI-based optimization of fleet and charge planning (T3.4). Firstly, functional requirements are defined. The functional requirements are linked to the general functional requirements as defined in WP1 and are further refined based on conversations with project partners and end-users. This way, specific requirements are defined for the FPT and the DTV. Additionally, in case of the public-charging UC, requirements for a charge-time estimation digital twin (DTC) are defined. Next, context diagrams are presented for the operational tools, indicating how the tools connect to one another and to other systems such as the Energy Management System (EMS) and the Charge Station Management System (CSMS). These interfaces are further detailed by listing protocols, messages and signals per interface. Lastly, a protocol is presented that will be used in the communication of power-profiles.
