NEK NSPEK 411:2020
Maritime electrical installations
For the preparation of this document it is considered that the IEC 62619:2017 contains the necessary basic requirements for lithium ion battery systems and that supplementary requirements for marine application are necessary.
NEK encourage stake holders to contribute to this document by providing input to improvements.
This document has been developed to meet the demand from the Norwegian maritime industry. Standards developed by IEC TC 18 in general covers this industry, however the technology for batteries currently moves faster than the development of international standards. At the time of publishing this document the revision work on batteries within IEC TC 18 is in the early stages of the revision process, which takes 33 months on an average. IEC 60092-305 and IEC 60092-401 are relevant standards that may include requirements to battery rooms as well as battery system requirements. IEC TC 18 may also develop standalone standards separate of the main maritime standard series for the purpose of specifying requirements to batteries.
The intention of this document is to provide a solution that contributes to the steps necessary to comply with the authority requirements. In that sense, this document alone may not be enough. Depending on a situation, other requirements may also be necessary, for example classification society rules or contractual requirements.
For the preparation of this document it is considered that the IEC 62619:2017 contains the necessary basic requirements for lithium ion battery systems and that supplementary requirements for marine application are necessary. Also, IEC 60092-302-2 is considered to contain relevant requirements.
This document constitutes an assessment of IEC 62619 to whether each requirement is suitable for maritime applications. Where IEC 62619:2017 is found insufficient, this document suggests additional or modified requirements.
