What is UN38.3 certification and why does the P100 battery pack need it?

UN38.3 is the internationally recognised standard for transport testing of lithium cells and batteries, requiring batteries to pass eight tests (T1–T8) covering altitude simulation, thermal cycling, vibration, shock, external short circuit, impact, overcharge, and forced discharge. The P100 battery pack requires this certification to be legally transported by air (IATA), sea (IMDG), or road (ADR) as a Class 9 dangerous good.

What model and specification is the battery pack covered by report WTH25D04093611B?

Key Details

The P100 battery pack was tested across multiple UN38.3 test sequences (T1 through T8). Samples were evaluated in two charge-cycle states — after the 1st cycle and after the 25th cycle — to ensure consistent safety performance throughout the battery’s operational life. The test environment was maintained at an ambient temperature of 20°C–25°C and relative humidity of 45%–75%.

Test Item	Sample Numbers	Sample State
T1–T5	B01# – B05#	1st charge/discharge cycle, fully charged state
T1–T5	B06# – B10#	After 25 cycles, fully charged state
T6	C01# – C05#	1st cycle, 50% of design rated capacity
T6	C06# – C10#	After 25 cycles, 50% of design rated capacity
