2026 has seen the publication of a major new update to EN ISO 16315.  With the 2026 version now in place the European marine sector has a modern, technically robust foundation for the next generation of electric and hybrid small craft.

The new standard defines requirements for both fully electric and hybrid propulsion systems, covering:

  • DC systems below 1,500 V
  • Single‑phase AC systems up to 1,000 V
  • Three‑phase AC systems up to 1,000 V

Providing detailed guidance on:

  • System architecture for AC, DC, and hybrid propulsion systems
  • Component requirements, including batteries, inverters, and control systems
  • Environmental and safety considerations, such as hazardous areas, ventilation, and fire protection
  • Electromagnetic compatibility (EMC) requirements
  • Installation rules ensuring proper segregation of AC and DC circuits
  • Testing, inspection, and documentation for compliance verification
 
Why this matters for the industry

This new unified reference for conformity assessment will give manufacturers a clear, harmonized framework for designing compliant electric propulsion systems.  Boatbuilders can more easily integrate hybrid and electric systems with confidence in safety and interoperability. The standard also supports broader EU goals for decarbonization and maritime environmental protection, as electric propulsion becomes increasingly central to sustainable boating.
