Limits the volume of flammable gases emitted by lithium ion cells propagated in a thermal runaway. • Results in a less energetic thermal runaway event if one should occur. • Reduces the likelihood of thermal propagation from cell to cell. • Harmonization facilitates international trade by minimizing the burden of complying with multiple or inconsistent safety requirements (although currently domestic shippers and carriers have the option to voluntarily comply with ICAO requirements). Consistency between regulations reduces compliance costs and helps to avoid costly frustrations of international shipments.
• Potential changes in manufacturing procedures to ensure compliance with state of charge provision. • Reevaluation of management practices and potentially instituting changes to avoid or lessen supply chain impacts such as reduced shelf life of batteries and battery quality issues. • Additional time for end users needed to charge the batteries from 30 percent state of charge or less instead of the typical levels of 40 percent or 50 percent at which manufacturers currently set the state of charge.
These estimates include only the cost for entities to apply for permission to ship batteries at higher charge levels.
