Scope
1.1 The purpose of this guide is to provide standard methods for the safe use of Li-ion batteries onboard vessels. The guidelines in this document were developed primarily for larger Li-ion marine battery installations, such as for propulsion or ships service electrical power. The guidelines may not be appropriate for smaller battery packages such as those for computers, packaged uninterruptible power supply (UPS) units, and tools.
1.2 Advances in energy storage technology have enabled new possibilities in shipboard power systems. Currently, lead acid batteries comprise the vast majority of shipboard power storage installations due to their low cost and predictable performance. Li-ion batteries are very energy dense, are becoming less expensive and make all-electric or hybrid-electric power systems possible on some types of vessels. There are many unique safety concerns related to Li-ion battery installations which are addressed here. Battery technology is rapidly developing and users should be aware of additional safety practices unique to each particular battery chemistry.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
