Standard for marine lithium batteries

　　The marking of marine batteries is also an important aspect of this standard. The name, specifications, capacity, working voltage, polarity, manufacturer, production date, and other information of the battery should be clearly marked in a prominent position. Valve controlled batteries should be labeled with the opening and closing pressures of pressure valves and safety valves, while self flowing batteries should be labeled with the position of the electrolyte addition port. Adequate labeling information not only facilitates manufacturers to trace quality, but also facilitates users to monitor and manage batteries.

　　To fully utilize batteries, this standard also specifies requirements for packaging, transportation, and storage of batteries. The packaging of batteries should comply with national and industry standards to ensure that they will not be damaged during transportation. The transportation of batteries should comply with relevant regulations and standards. Battery storage should be carried out in a cool, dry, ventilated, non corrosive gas, and direct sunlight environment to avoid damage and premature aging of the battery.

　　This standard provides comprehensive and detailed specifications for the design, manufacturing, use, management, and maintenance of marine batteries, and can provide safer and more reliable battery products for the shipbuilding industry. In the process of formulation and implementation, it is necessary to combine practical requirements and the latest technological development trends to ensure that standards are closely related to market demand and provide more valuable driving effects for the industry. With the increasing awareness of environmental protection, marine batteries are also facing higher requirements for green environmental protection. Therefore, this standard combines green environmental protection requirements with technical standards, providing strong support for the green development of marine batteries.

　　Specifically, this standard imposes strict environmental requirements on the materials, processes, and usage of batteries. The materials inside the battery should comply with national environmental regulations and standards, and materials containing harmful substances such as heavy metals and hexavalent chromium should not be used. The manufacturing process of batteries should use environmentally friendly materials and processes as much as possible to avoid adverse effects on the environment. In the use and management of batteries, environmental protection concepts should also be emphasized, and discarded batteries should be fully utilized and recycled.

　　In addition to environmental requirements, this standard also specifies the testing methods and inspection rules for batteries. The inspection of the working voltage and capacity of the battery can be carried out using discharge testing methods to verify whether the performance of the battery meets the requirements. The firmness and contact of the terminals, wiring, and connectors of the battery need to be inspected using visual inspection and electrical testing methods to ensure that the battery can be connected to the circuit normally. The additional testing content for valve controlled sealed batteries and self flowing sealed batteries needs to be verified according to specific requirements.

　　It should be noted that sufficient protection and safety measures must be taken for the battery during use and testing. Professional testing equipment should be used when testing batteries, and safety measures should be taken according to the actual situation to avoid battery safety accidents.
