Retrofitting boats with lithium-ion batteries is becoming increasingly popular. The advantages are obvious: higher energy density, lower weight and longer service life compared to conventional lead-acid batteries. But what many people don’t realize is that retrofitting also runs the risk of losing the boat’s CE certification – with very serious consequences!
The role of the Recreational Craft Sectoral Group (RSG)
The Recreational Craft Sectoral Group (RSG) is an important authority in the field of recreational craft. It coordinates cooperation between authorized certification providers (Notified Bodies) and ensures a uniform interpretation of the Recreational Craft Directive (RCD). This EU directive defines the basic safety and environmental requirements for recreational craft sold or put into service in the European Union.
The pitfall: RSG recommendation no. 199
The RSG has dealt intensively with the topic of lithium-ion batteries in boats. In its RECOMMENDATION FOR USE No. 199, it comes to the conclusion that the replacement of conventional batteries with lithium-ion batteries constitutes a “major craft conversion” within the meaning of RCD Article 3 (7).
What does this mean for boat owners?
This conclusion of the RSG has far-reaching consequences for boat owners who are planning to retrofit lithium-ion batteries or have already done so:
- Loss of CE certification: The RSG argues that a significant change to the boat can lead to the original CE certification becoming invalid. The boat may then no longer comply with the applicable safety and environmental requirements.
- Liability risks: A boat without valid CE certification can lead to considerable liability risks for the owner in the event of damage. Insurance companies may refuse to pay benefits and there may be legal consequences in the event of an accident.
- Reassessment required: In order to restore CE conformity after retrofitting, it is usually necessary to have the boat reassessed by an authorized body. This can involve considerable effort and costs.
Why this strict interpretation?
The RSG justifies its strict interpretation with the potential risks associated with lithium-ion batteries. Improper installation, faulty battery systems or a lack of protective measures can lead to fires, explosions or other dangerous situations.
What should boat owners do?
If you are planning to retrofit your boat with lithium-ion batteries or have already done so, you should take the following steps:
- Avoid any DIY work: Electrical systems are not a playground for experimentation. Leave the planning and installation of lithium-ion systems exclusively to specialized companies.
- Consult the manufacturer: Consult the manufacturer of the boat and clarify to what extent such a conversion affects or jeopardizes the existing CE certification.
- Select certified components: Only use marine-certified battery systems and components.
Conclusion
Retrofitting boats with lithium-ion batteries is a complex matter that requires careful planning and implementation. The RSG recommendation makes it clear that CE certification can be jeopardized if the retrofitting is not carried out professionally. Boat owners should therefore obtain comprehensive information and seek professional support in order to minimize risks and ensure the safety of their boat.
