Design & development of hyper vessel charger (WP3)

Deliverable 3.1 addresses the need for standardized charging solutions in the electric vessel market. As discussed in previous deliverables, these solutions should be flexible, adaptable, and have a standardized communication interface. Within this study we discuss the architecture, communication, and power conversion topology of the proposed multi-MW charger in order to meet these requirements.

To ensure standardization, an alternative EVSE-EV communication protocol is proposed, combining the Mega-Watt Charging System (MCS) with wireless communication for an infrastructure-mounted Auto-connect Charging Device (ACD). In this context, the system architecture is defined, the functions of the individual components are described and their interfaces are explained.

Safety and security aspects will be addressed in detail, taking into account the results of the previous work packages. Special attention is given to the identification and treatment of corrosion risks. Thus, a method for measuring and compensating for these effects can be given. It also tackles the challenges of insulation monitoring and suggests a distributed solution for handling increasing complexity and system capacitance.

The report recognizes that the number of contact pins of the ACD is limited compared to the MCS connector definition. It proposes an alternative communication method that uses wireless communication in conjunction with MCS.

Finally the modularity of the EVSE and its components is discussed, with a focus on the power conversion topology and the necessary level of granularity in the modules. The report emphasizes the need for more detailed component information and explains the dependencies for electro-thermal modeling.
