What is the ICAO SoC limit for lithium ion batteries?

Recently, ICAO took a decision to extend that 30% SOC restriction to air shipments of lithium ion batteries packed with equipment. This SOC limit will become effective January 1, 2026, but it is recommended that these batteries are held to a SOC not exceeding 30% of their rated capacity beginning January 1, 2025.

How accurate is SOC in Li-ion batteries?

It has been recognized that the reduction of SOC from 100% to 30% SOC reduces significantly the hazards of Li-ion batteries. Although no accuracy for the SOC has been specified in the regulation, it can be admitted that an accuracy in the range of a few percent is fulfilling the requirement of the control regulation.

What is SOC in a battery?

The SOC is the available capacity stored in a battery, expressed as a percentage of the rated capacity (see definitions in annex 2). The graph below shows the relation between the battery voltage curve, the rated capacity, and the SOC. How to know the Rated capacity?

Does a battery export for NEM credit?

ensure that a battery does not export for NEM credit.Since PCS are control devices, as opposed to a signaling device which trips a circuit breaker at a definite time delay (like a relay does), their response times are characterized in terms of open loop response time (OLRT), which reflects the time for the outpu

Are sodium ion batteries safe to ship?

One such chemistry, sodium-ion batteries, has recently been introduced into the dangerous goods regulations with the creation of new UN numbers. For now, the shipping requirements for sodium ion batteries will mirror the lithium-ion rules.

What are battery rules in CAISO vs ERCOT?

Battery rules in CAISO differ from ERCOT in numerous ways. Regarding battery SOC during the provision of ancillary services, CAISO requires a battery to maintain 50% of the energy required to deliver a nameplate ancillary award in the upcoming hour (vs 100% in the case of the new ERCOT BPM SOC expectations).
