Storage battery requirements
The following is a short summary of the requirements in these codes for stationary storage battery systems. Please note that these two
Recent advances in the development of Li-ion chemistry are facilitating their use for energy storage in applications that were previously the domain of more traditional battery chemistries and have opened the door to new applications. The fundamental element of a lithium-ion battery system is the lithium-ion cell.
• Except for vehicles transported by highway, rail, or vessel with prototype or low production lithium batteries securely installed, each lithium battery must be of a type that has successfully passed the UN 38.3 tests, unless approved by PHMSA's Associate Administrator.
The battery system enclosures installed in a battery space are to have a degree of protection not lower than IP44. For battery system enclosures installed on an open deck an IP67 rating is required. Accessible parts of the battery system are to have no sharp edges, sharp angles or rough surfaces likely to cause injury.
Revised Packing Instructions: More stringent requirements for UN-certified packaging, capable of withstanding specific drop tests. State of Charge (SoC) Emphasis: Increased scrutiny on the SoC for standalone lithium-ion battery shipments, with a general requirement not to exceed 30% of rated capacity.
