To ensure the safe transportation of energy storage containers, the following lithium battery testing requirements are outlined in the guidelines:
The battery packs in energy storage containers must pass the eight tests (T1-T8) specified in Section 38.3 of the United Nations "Manual of Tests and Criteria."
Energy storage containers must implement measures to prevent thermal runaway propagation between batteries and hold a recognized test report. Common prevention methods include:
Using thermal insulation materials (e.g., ceramic fiber, silicone) to reduce heat transfer.
Installing temperature monitoring devices to promptly control battery pack temperatures.
The battery packs must undergo salt spray and insulation performance tests according to the "Lithium-ion Batteries for Power Storage" (GB/T 36276) standard, with recognized test reports to ensure corrosion resistance and operational stability in marine climates.
According to Section 2.3 of the guidelines, the battery enclosures in energy storage containers must meet the following requirements:
The protection rating is expressed using the IP rating system, where the first digit represents the protection level against solid objects (0-6), and the second digit represents the protection level against liquids (0-9).
Energy storage containers are classified as Class 9 dangerous goods (UN Number 3536) under the International Maritime Dangerous Goods (IMDG) Code and must meet the following requirements for sea transport:
The container must have Class 9 dangerous goods labels and the United Nations number affixed on all four sides.
The container body must meet the requirements of container inspection standards and hold a Certificate of Inspection issued by a ship inspection body recognized by the national maritime authority. The safety approval plate in compliance with the 1972 International Convention for Safe Containers (CSC Convention) must be displayed.
To ensure the safety and reliability of energy storage containers during transportation, the packing process must meet the following requirements:
The battery packs must be securely fixed inside the container, with appropriate control and fire suppression systems. The rigid support structures or cabinets securing the battery packs must be strong enough to withstand the load and inertial forces during transportation without causing safety-related deformation or damage.
The initial state of charge (SoC) of the energy storage container must be 30% or below, ensuring the batteries remain in a low charge state during transport to reduce the risk of fire or other safety issues.
The packing process must be inspected, and a "Container Packing Certificate" must be issued and signed by the packing inspector. Due to the special nature of energy storage containers, which serve as both transportation components and product enclosures, it is not possible to supervise the packing process during containerization.
