Test specification
T2
Thermal test
(UN38.3-2)
2-1. Packs are stored for 6 hours at 72℃±2℃, followed by storage for
6 hours at -40℃±2℃. The maximum time interval between test
temperature extremes is 30 minutes.
2-2. Repeat 2-1 for 10 times. Then store the packs at ambient for 24
hours. All packs weight are measured. The charged battery
voltage are measured and recorded.
T3
Vibration test
(UN38.3-3)
3-1. Packs are firmly secured to the platform of the vibration machine
without distorting the packs in such a manner as to faithfully
transmit the vibration. The vibration shall be a sinusoidal
waveform with a logarithmic sweep between 7 and 200 Hz and
back to 7 Hz traversed in 15 minutes. This cycle shall be repeated
12 times for a total of 3 hours for each of 3 mutually perpendicular
to the terminal face.
3-2. The logarithmic frequency sweep is as follows:
7-18 Hz  1gn
18-50 Hz  0.8mm amplitude
50-200 Hz  8gn
3-3. All packs weight are measured. The charged packs voltage are
measured and recorded.
T4
Shock test
(UN38.3-4)
4-1. Packs shall be secured to the testing machine by means of a rigid
mount, which will support all mounting surfaces.
4-2. Packs shall be subjected to a half-sine shock of peak acceleration
150gn and pulse duration of 6 milliseconds. Each pack shall be
subjected to 3 shocks in the positive direction followed by three
shocks in the negative direction of three mutually perpendicularly
mounting positions of the pack for a total of 18 shocks.
4-3. All batteries weight are measured. The charged cell voltage are
measured and recorded.
T5
Short Circuit
Test
(UN38.3-5,
5-1. Packs are placed in to a 57℃±4℃ oven, and exterior packs
temperature are monitored
5-2. When packs exterior reach 57℃±4℃, they are shorted by
connecting terminals with a copper wire of resistance less than
100 mOhm.
5-3. The short was continued for more than 1hour or the cell
temperature return to 57℃. The packs are observed for a further 6
hours.
T6
Impact test
(UN38.3-6)
6-1. Cell’s diameter ≧ 18mm, Execution impact test. (A 9.1 Kg mass is
to be dropped from a height of 61±2.5cm onto the sample.)
6-2. Cell’s diameter ＜ 18mm, Execution crush test (The cells are
crushed with a 13 KN with the crush tester. Once the force is
obtained it is to be released.)
T7
Overcharge test
(UN38.3-7)
7-1. The charge current shall be twice the SPEC’s recommended
maximum continuous charge current.
7-2. The minimum voltage of the test shall be as follows:
(a) When the SPEC’s recommended charge voltage is not more
than 18V, the minimum voltage of the test shall be the lesser of
two times the maximum charge voltage of the battery or 22V.
(b) When the SPEC’s recommended charge voltage is more than
18V, the minimum voltage of the test shall be 1.2 times the
maximum charge voltage.
7-3. Tests are to be conducted at ambient temperature. The duration
of the test shall be 24 hours.
