ROYPOW Marine Lithium Battery Systems Achieve DNV Type Approval

On June 25, 2025, during the prestigious Electric & Hybrid Marine Expo Europe held in Amsterdam, ROYPOW proudly announced that its marine lithium battery systems have successfully obtained DNV Type Approval. This achievement signifies a pivotal advancement in ensuring the safety and regulatory compliance of maritime operations, setting new benchmarks in the industry for reliability and efficiency.

What is DNV Type Approval?

DNV Type Approval is a highly esteemed and rigorous certification granted by DNV, one of the world's leading classification societies in the maritime sector. This certification evaluates whether a product meets strict international safety and performance standards within the maritime domain, undergoing exhaustive testing to establish its credibility.

The Comprehensive Evaluation

As part of the evaluation process, DNV conducted an extensive review of the ROYPOW marine battery systems, assessing various critical factors such as system design, electrical safety, battery durability, adaptability to environmental conditions, electromagnetic compatibility (EMC), functional safety, and compliance with environmental demands. The evaluation adhered to the standards set forth by DNV0339, DNV0418, DNV Pt.6 Ch.2 Sec.1 Non-Propagation Test, IEC 62619, and IEC 61000. Furthermore, DNV evaluated ROYPOW's capabilities, including its research and development strength, manufacturing capacity, process control, and overall quality management system.

Benefits for Maritime Stakeholders

For ship owners, operators, and system integrators, DNV-certified systems are widely recognized by global regulatory authorities, facilitating faster adoption and simpler regulatory compliance. These advancements lead to cost reductions, particularly in regions with stringent carbon regulations. The DNV certification also assures proven reliability, significantly lowering maintenance costs while securing long-term investment viability. ROYPOW’s marine battery systems are designed to reduce operational costs, save fuel, and help achieve environmental targets within the shipping industry.

Technical Features and Scalability

The innovative battery systems showcase a modular design comprising LiFePO4 battery modules, Power Distribution Units (PDU), and Distribution Control Blocks (DCB). This structure allows for flexible scalability, supporting configurations up to 1000V and 2785kWh per system. By connecting multiple systems in parallel, users can achieve capacities of over 100MWh.

Each battery system features an advanced Battery Management System (BMS) with a robust three-tier architecture, independent hardware protection, integrated fire suppression features, a High Voltage Interface Loop (HVIL) design for all electrical connections, and a gas venting system. These features ensure optimal performance even in challenging marine environments.

Wide Compatibility Across Marine Applications

Versatility is a hallmark of the ROYPOW system, making it compatible with a wide array of vessels. From hybrid and fully electric ships to offshore platforms, the systems are ideal for ferries, workboats, passenger ships, tugs, luxury yachts, LNG tankers, offshore supply vessels (OSVs), and aquaculture applications.

Commitment to Future Developments

Looking ahead, ROYPOW remains committed to delivering high-performance, safe, and sustainable energy solutions that meet the evolving demands of the marine industry. The acquisition of the DNV Type Approval is not just a milestone; it is a stepping stone towards enhancing maritime safety, sustainability, and technological advancement.
