marine lithium battery systems from ROYPOW gain DNV's type approval, signifying compliance with industry safety and performance standards.
The maritime industry has taken a significant step forward with the recent DNV Type Approval of ROYPOW's marine lithium battery systems. This globally recognised certification, issued by DNV, a leading maritime classification society, signifies that ROYPOW's battery systems meet stringent international standards for safety and performance in marine applications.
The approval process involved a comprehensive evaluation of the ROYPOW marine battery system, covering system design, electrical and battery safety, environmental adaptability, EMC, functional safety, and environmental requirements under various standards. Key features of the system, such as its high voltage interrupting system (HVIL) for safety, advanced BMS with a stable three-level architecture, and integrated fire extinguishing system, were closely scrutinised.
The certification offers enhanced safety assurance, as the battery system complies with rigorous tests designed to reduce risks associated with battery failures. The system was tested against multiple relevant standards, including DNV0339, DNV0418, IEC 62619, and IEC 61000, ensuring its suitability for the harsh and complex marine environment.
ROYPOW's commitment to delivering high-performance, safe, and sustainable solutions for the evolving needs of the maritime industry is evident in their systems' design. The battery system is suitable for various types of vessels, including ferries, work boats, luxury yachts, and offshore platforms, and is compatible with hybrid or fully electric vessels.
The system's modular design, composed of LiFePO4 battery modules, power distribution unit (PDU), and direct current bus (DCB), offers flexible scalability. It can support up to 1000V / 2785kWh per system and can reach up to 100MWh when multiple systems are connected in parallel. A gas extraction system is also included for reliable performance in harsh marine conditions.
The DNV Type Approval offers market and operational advantages. Being one of the few companies worldwide to achieve this certification, ROYPOW raises the bar for certified energy solutions in the marine industry. This approval helps shipowners and operators select battery systems with verified safety and performance, potentially easing regulatory acceptance and insurance processes while supporting the industry’s transition to cleaner, more reliable energy storage solutions.
In summary, ROYPOW's DNV Type Approval enhances confidence in their marine lithium battery systems by guaranteeing compliance with stringent safety, performance, and environmental standards, thereby supporting safer, more efficient, and environmentally sustainable maritime operations. The approval was granted on June 25, 2025, at the Electric & Hybrid Marine Expo Europe 2025 held at RAI Amsterdam. The systems are designed to reduce operational costs, save fuel, and meet environmental targets for maritime operations.
The DNV Type Approval, a recognition granted to ROYPOW's marine lithium battery systems, underscores their compatibility with the stringent safety and performance standards of the finance and energy sectors within the maritime industry. This approval was given after the system underwent rigorous evaluations in data-and-cloud-computing, covering design, safety, adaptability, EMC, functional safety, and environmental requirements. The technological advancements incorporated in the system, such as the high voltage interrupting system, BMS, and fire extinguishing system, have been verified as cutting-edge solutions for the future of business in the maritime industry.
