DNV issues type-approval for ROYPOW marine lithium battery systems

Class society DNV has awarded type-approval certification to ROYPOW marine lithium battery systems, signifying they meet strict international standards for safety and performance in marine applications through rigorous testing. The achievement was announced at the Electric & Hybrid Marine Expo Europe 2025 in Amsterdam.

DNV conducted a comprehensive, strict evaluation of the ROYPOW marine battery system, covering system design, electrical and battery safety, environmental adaptability, EMC, functional safety, and environmental requirements under the standards such as DNV0339, DNV0418, DNV Pt.6 Ch.2 Sec.1 Non-Propagation Test, IEC 62619, and IEC 61000. As part of the type-approval process, DNV assessed ROYPOW’s overall capabilities, including R&D strength, manufacturing capacity, process control and quality management system.

ROYPOW Technology said its marine battery systems are designed with LiFePO4 battery modules, PDU and DCB, offering flexible scalability, supporting up to 1,000 V/2,785 kWh per system and reaching up to 100 MWh when multiple systems are connected in parallel.

Safety is prioritised for harsh marine environments through an advanced battery management system with a stable three-level architecture, independent hardware protection, an integrated fire extinguishing system in each battery, an HVIL design for all power connectors, and a gas extraction system. Additionally, the system is well suited for hybrid or fully electric vessel applications and offshore platforms.
