The conceptual design for a battery system for retrofitting and powering various vessel
sizes addresses safety, mechanical, electrical, and thermal challenges. The system will
be analysed and designed for modularity, eco-design principles, and safety, aiming to
reduce costs and weight, enhance safety, and increase energy density.
The design process involves three steps: considering vessel application requirements
(WP1), creating a rough battery module geometry using optimization techniques, and
performing a rough thermo-mechanical design of the battery pack.
The project’s BESS conceptual design will start with a detailed set of boundaries and
requirements, ensuring functionality and adaptability for two distinct vessels. Key aspects
include defining energy capacity, power output, voltage range, discharge/charge rates,
weight, size limitations, and mounting options. It also involves ensuring seamless
integration with existing vessel architecture, considering spatial constraints, ventilation,
and access compatibility. Strict safety protocols will be incorporated, addressing battery
chemistry, thermal management, fire suppression, and electrical isolation. Additionally, a
strategy will be established to maintain optimal battery temperatures for longevity and
safety.
The design will cater to multi-vessel application by creating a core set of requirements for
interchangeability and maximum utility across both vessels. Flexibility will be included for
potential variations, such as modular battery packs or adjustable mounting systems.
Information from D1.2, D2.1 and D2.4 will guide these requirements, ensuring alignment
with project objectives and vessel characteristics. This comprehensive approach will yield
a robust, effective, and adaptable BESS design for both vessels.
This analysis involved creating multiple design options at both the module and system
levels by varying the series and parallel configurations of battery cells. Each architecture
was evaluated based on ease of use, cost, weight, safety, and modularity. This comparison helped identify the optimal design that balances performance, costeffectiveness, and safety for each vessel.
The design process considered several key factors for selecting battery cells, including
operating voltage, voltage range, energy capacity, weight, physical footprint, and cost.
These factors ensured the chosen cells met the specific requirements and operational
constraints of the vessels.
Both vessels require a BESS with a voltage between 700V and 1000V, so the series
configuration of cells will be the same for both. However, their energy storage capacities differ, with the Gunnerus needing 1 MWh and the Atatürk needing 3 MWh. This necessitates different parallel configurations, highlighting the need for a scalable design. The BESS design prioritizes a modular configuration that allows for scalability in parallel connections to meet the varying capacity demands. This ensures the system can be tailored to the specific needs of both the Gunnerus and Atatürk vessels by adjusting the number of parallel modules. The resulting BESS design will effectively accommodate the
desired voltage and capacity requirements for each vessel.
