Revolutionising Marine Battery Safety: PowerStack Achieves DNV Certification with Dukosi Technology
In a significant development for the electric vessel sector, Nordic Marine Power (NMP) has officially announced that its PowerStack battery system has received DNV type approval. This prestigious certification, a global benchmark for maritime and industrial safety, was made possible by integrating Dukosi’s advanced Cell Monitoring System (DKCMS).
The DNV type approval is a crucial endorsement, confirming that the PowerStack system meets the rigorous safety and environmental standards required for installation on all vessels classified by DNV. This achievement marks a pivotal moment for both companies and sets a new precedent for marine battery systems.
The Critical Role of DNV Type Approval in Marine Applications
DNV type approval stands as a globally recognised third-party certification. It serves as an unequivocal confirmation of compliance with the most demanding maritime, offshore, and industrial safety and environmental standards. For battery systems intended for marine use, this certification is not merely a formality but a fundamental necessity.
The operational environment for marine battery systems presents unique and elevated safety requirements compared to those found in typical electric vehicle (EV) or stationary energy storage applications. Vessels operate in confined spaces, often far from immediate assistance, necessitating exceptional fire suppression capabilities and robust reliability under remote operating conditions.
Achieving DNV certification demonstrates that a marine battery system has undergone exhaustive testing and evaluation, proving its resilience and safety against potential hazards like thermal runaway, structural integrity issues, and environmental stressors inherent in maritime operations. This stringent vetting process assures vessel operators, regulators, and insurance providers of the system’s trustworthiness.
Dukosi’s Innovative Cell Monitoring System (DKCMS)
At the heart of Nordic Marine Power’s certified PowerStack lies the Dukosi Cell Monitoring System (DKCMS), a technological breakthrough in battery management. Unlike traditional battery architectures that typically employ only a few temperature sensors per module, the DKCMS adopts a sophisticated chip-on-cell approach.
This innovative design places a dedicated cell monitor chip directly onto each individual battery cell. This allows for the simultaneous measurement of both temperature and voltage on every single cell within the battery system. This granular level of data acquisition offers unparalleled insights into the real-time health and performance of the battery pack.
The data collected synchronously from each cell is then relayed to the battery management system (BMS) with deterministic latency, ensuring timely and accurate information flow. This capability is vital for proactive safety management and optimising battery performance over its lifespan.
Advanced Thermal and Voltage Monitoring
One of the most significant advantages of the DKCMS is its enhanced ability to detect overtemperature events much earlier than legacy systems. With a sensor on every cell, localised hotspots or potential thermal issues can be identified almost instantaneously. This early detection mechanism is critical in preventing cascading failures or thermal runaway events, which can have catastrophic consequences, especially in marine environments.
Furthermore, the system is designed to alert the BMS processor even when it is operating in a deep sleep mode, ensuring that critical safety warnings are never missed. This persistent monitoring capability significantly bolsters the overall safety profile of the battery system.
Contactless Communication with C-SynQ Protocol
Communication between the individual cell monitors and the central BMS is facilitated by Dukosi’s proprietary C-SynQ contactless protocol. This advanced communication method simplifies integration into complex battery systems, reducing wiring complexity and potential points of failure. The contactless nature also contributes to improved design flexibility, allowing manufacturers like Nordic Marine Power to streamline their production processes and meet challenging project deadlines with greater confidence.
Nordic Marine Power’s Strategic Advantage with PowerStack
For Nordic Marine Power, the integration of Dukosi’s novel contactless battery architecture into their PowerStack system has provided a distinct competitive edge. Jonas Roald Nordstrand, CEO of NMP, highlighted the direct impact of this technology on their certification journey.
“Dukosi’s novel contactless battery architecture uniquely provides per-cell temperature sensing that improves safety compared to legacy systems,” stated Mr. Nordstrand. He further elaborated, “Having a Dukosi Cell Monitor chip on each cell gives us greater real-time insights into every cell’s behavior, which has allowed us to accelerate achieving DNV certification. Their chip-on-cell technology with C-SynQ simplifies integration into our battery systems, while also providing valuable design flexibility, allowing us to streamline production to meet tight deadlines with confidence.”
This strategic collaboration has not only accelerated NMP’s path to DNV approval but also enhanced the inherent safety and reliability of their PowerStack battery solutions, making them a preferred choice for the burgeoning electric marine industry.
