Dukosi Chip-on-Cell Monitoring System Enables Nordic Marine Power’s PowerStack to Achieve DNV Type Approval

Why It Matters

The approval validates a scalable safety solution for marine batteries, accelerating market adoption and reducing certification costs for shipbuilders. It also showcases the competitive edge of chip‑on‑cell technology in meeting rigorous offshore safety regulations.

Key Takeaways

• Dukosi places a monitor chip on every battery cell.
• Real-time per‑cell temperature and voltage data reduces over‑temperature risk.
• C‑SynQ contactless protocol enables deterministic latency even in deep‑sleep BMS.
• DNV type approval opens PowerStack to all vessels classed by DNV.
• Early fault detection speeds marine battery certification and production timelines.

Pulse Analysis

Marine electrification is gaining momentum, but safety remains the chief barrier to widespread battery adoption on vessels. DNV’s type approval is the gold standard for maritime equipment, confirming compliance with fire‑suppression, environmental, and operational criteria that far exceed those for land‑based electric vehicles. By securing this certification, Nordic Marine Power demonstrates that its PowerStack can meet the rigorous demands of confined shipboard spaces, remote operations, and strict regulatory oversight, positioning the system as a viable alternative to diesel generators for a broad range of commercial and offshore vessels.

The technical edge comes from Dukosi’s chip‑on‑cell architecture. Unlike legacy designs that rely on a handful of temperature sensors per module, DKCMS attaches a miniature monitor to every cell, capturing voltage and temperature in real time. The data is transmitted via the proprietary C‑SynQ contactless protocol, which guarantees deterministic latency even when the battery management system is in a low‑power sleep state. This granular insight enables the BMS to flag overheating conditions instantly, reducing the risk of thermal runaway and simplifying compliance with DNV’s stringent safety thresholds. The contactless design also streamlines wiring, cutting weight and assembly time—critical factors for marine applications where space and weight are at a premium.

The broader market implications are significant. With DNV approval, PowerStack can be specified for any vessel under DNV’s classification, opening doors to cruise ships, ferries, offshore support vessels, and even autonomous marine platforms. The faster certification timeline translates to lower development costs and quicker time‑to‑market, encouraging shipyards and OEMs to consider lithium‑ion solutions over traditional fossil‑fuel systems. Moreover, the demonstrated reliability of per‑cell monitoring may spur adoption in other high‑risk sectors such as offshore wind, mining equipment, and aerospace, where safety and real‑time diagnostics are equally paramount.
