ROYPOW Marine Lithium Battery Systems Achieve Significant DNV Type Approval

On June 25, 2025, ROYPOW unveiled its marine lithium battery systems, which were awarded the esteemed DNV Type Approval at the Electric & Hybrid Marine Expo Europe 2025 in Amsterdam. This accomplishment represents a pivotal development in enhancing safety and compliance within the maritime sector. As one of the few companies globally attaining this certification, ROYPOW sets a new standard for safe, reliable, and certified energy solutions designed for marine applications.

Understanding DNV Type Approval

DNV Type Approval is recognized as a rigorous certification framework, dispensed by DNV, a preeminent maritime classification society. The certification validates that ROYPOW's products fulfill strict international standards regarding safety and operational performance in marine settings through exhaustive testing and evaluation. The process involved detailed scrutiny of the battery system's design, electrical safety, environmental compatibility, electromagnetic compatibility (EMC), and functional safety, in compliance with various standards including DNV0339, DNV0418, IEC 62619, and IEC 61000.

Furthermore, DNV assessed ROYPOW’s overall capabilities, including research and development robustness, manufacturing capacity, process control, and quality management systems, solidifying the credibility of ROYPOW’s offerings.

Implications for the Maritime Industry

For stakeholders in the maritime industry—including shipowners, operators, and system integrators—systems with DNV certification carry significant weight. This certification is recognized by global regulatory bodies, enabling streamlined deployment processes, enhanced compliance, and reduced regulatory expenditures, particularly in areas with stringent carbon regulations. Achieving DNV Type Approval not only guarantees reliability but also lowers maintenance costs, thus fostering more secure and economical long-term investments.

Designed to optimize operational expenses, ROYPOW’s marine battery systems support fuel savings and align with environmental objectives critical for maritime operations. The modular structure, consisting of LiFePO4 battery modules, Power Distribution Units (PDU), and Battery Control Boards (DCB), allows for expandable solutions, accommodating voltages up to 1000V and reaching a capacity of 2785kWh per system, potentially scaling to 100MWh when interconnected.

Commitment to Safety and Sustainability

Safety remains a central tenet of ROYPOW’s design philosophy. Advanced Battery Management Systems (BMS) featuring a tri-level architecture prioritize safety and reliability. Each battery unit is equipped with independent hardware protection, integrated fire suppression systems, and a gas extraction mechanism, ensuring dependable functionality even in severe marine conditions. The systems also exhibit extensive compatibility, making them suitable for diverse vessels and offshore platforms, from hybrid to fully electric applications—including ferries, tugs, luxury yachts, LNG carriers, and offshore support vessels (OSVs).

As the industry continues to evolve, ROYPOW is dedicated to delivering high-performance, safe, and sustainable energy solutions that meet the changing demands of maritime operations. Their recent DNV Type Approval is not merely a milestone, but a testament to their commitment to innovation and excellence in marine energy technology.
