Use Case definition, specs and Requirements (WP1)

This work package focuses on the specifications and requirements with the goal of defining the specific HYPOBATT use case. By analysing the current and future hyper power charger technologies a complete set of specifications and requirements applicable for all relevant ships and ports is to be established.

The following reports are, or will be, available. If the reports are classified as confidential, you will receive a comprehensive overview here.

Port integration and grid interface requirements

This study addresses requirements for the design, installation, and operation of a hyper-power charger for electric vessels in a realistic port environment. Based on the results of the market study in D1.2, it was determined that most electric vessels operate in Europe; therefore, the requirements are mainly defined for European port locations. The ports of Valencia in Spain and Norddeich and Norderney in northern Germany are specifically studied as use cases for the HYPOBATT project. 

Although there are no specific requirements for the installation and operation of hyper-power chargers, a major conclusion is that requirements from similar (electrical) applications can be used for many aspects. These requirements are usually specific to the site, but are often based on underlying international standards and regulations (as defined in D1.1). 

The power requirements for hyper-power chargers are high and are not always met by the port's electrical grid. A connection to the main distribution grid is required, or alternatively, local power generation and energy storage in the form of a smart microgrid may be a solution. This means that power availability and other aspects of the power grid must be assessed for each facility. 

The maritime environment and a variety of other weather and air pollution conditions must be considered to protect the facilities. In addition, ports can be located in an industrial environment with heavy transport equipment and industrial air pollution, as well as in an urban environment (e.g., city ferries) with additional requirements for noise emission levels. 

For port battery system security and cybersecurity requirements, design and installation can be based in part on standards and regulations, but a risk-based approach is still required.

Modular multi-MW charger, connector, and ship interface requirements

Based on the results of the previous studies D1.1, D1.2 and D1.3, this Report describes the planned battery charging system in terms of its main functions and main components, with the associated interfaces and performance requirements. In doing so, the report summarizes all relevant information and integrates it with other charging system requirements. 

Since this type of system is relatively new to the marine industry, there are few applications and no path to standardization yet. Through the results of the previous studies a list of categorized specifications, requirements and proposals for the charging system could be created and weighted in relation to the HYPOBATT project objectives and KPIs.  

The identified requirements cover the necessary aspects to create a realistic and manufacturable system with modularity and interoperability capabilities. 

To facilitate the design phases, the requirements were detailed and identified according to a specific description to allow easy and effective referencing. 

The results also address conformance and the lack of standardization in maritime charging systems to enable safe application of the system.
