ROYPOW's Maritime Lithium Battery Systems Achieve DNV Type Approval

On June 25th, 2025, ROYPOW proudly announced that its maritime lithium battery systems received the highly sought-after DNV type approval at the Electric & Hybrid Marine Expo 2025 held in Amsterdam. This certification marks a significant milestone in maritime safety and compliance, placing ROYPOW among the few companies worldwide that have successfully achieved such rigorous certification.

Understanding DNV Type Approval

DNV (Det Norske Veritas) is recognized globally as one of the leading maritime classification authorities, and its type approval signifies a product has met stringent international safety and performance standards in maritime applications. The process involves extensive testing to evaluate crucial factors such as system design, electrical safety, environmental adaptability, and compliance with environmental and operational regulations.

For ROYPOW, this approval was a culmination of rigorous assessments conducted by DNV, which comprehensively reviewed the company's capabilities in research and development, production capacity, process management, and quality control systems. This approval enhances ROYPOW's credibility among ship owners, operators, and system integrators, as DNV-certified systems are recognized by global regulators, facilitating speedier implementation and reducing compliance costs.

the Benefits of DNV-Type Certified Systems

The certification not only confirms the reliability of ROYPOW's systems but also translates into lower maintenance costs and safer long-term investments. ROYPOW's maritime battery systems are engineered to reduce operational costs, improve fuel efficiency, and meet environmental sustainability goals. The modular design consists of LiFePO4 battery modules, a Power Distribution Unit (PDU), and a Battery Communication Board (DCB), providing flexible scalability and supporting up to 1000 V/2785 kWh per system. Multiple systems can be connected in parallel to achieve power levels up to 100 MWh.

Safety is prioritized through an advanced Battery Management System (BMS) featuring a robust three-level architecture, independent hardware protection, built-in fire suppression systems within each battery, and a Gas Extraction System (GES) designed to ensure reliable performance even in harsh marine conditions.

The system's broad compatibility makes it suitable for various marine applications, including hybrid or fully electric vessels and offshore platforms such as ferries, workboats, passenger vessels, tugboats, luxury yachts, LNG tankers, Offshore Supply Vessels (OSVs), and aquaculture farms.

Future Commitments

Looking ahead, ROYPOW is committed to delivering high-performance, safe, and sustainable solutions that cater to the evolving demands of the maritime industry. The achievement of DNV type approval is not just a milestone but a stepping stone towards a cleaner, more efficient future for maritime operations.
