Storage after pritial use

6.2.2.1

An undischarged battery is discharged under an application/service output test condition,with the lowest resistive load test as defined in iec 60086-2 until the service life falls by 50% of the minimum average duration (MAD) value,followed by storage at (45±5)℃ for 30 days.

Requirements:there shall be no leakage,no fire and no explosion during this test.

Transportation-shock

6.2.2.2

An undischarged battery shall be tested as follows.

The shock test shall be carried out under the conditions defined in Table 3 and the

sequence in Table 4.

Shock pulse – The shock pulse applied to the battery shall be as follows:

Table 3 – Shock pulse

Table 4 – Test sequence

Step 1 Record open circuit voltage in accordance with 5.2.

Steps 2 to 4 Apply shock test specified in Table 3 and the sequence in

Step 5 Rest battery for 1 h.

Step 6 Record examination results.

Requirements

There shall be no leakage, no fire and no explosion during this test.

Transportation-vibration

6.2.2.3

An undischarged battery shall be tested as follows.

The vibration test shall be carried out under the following test conditions and the sequence in Table 5.

Vibration – A simple harmonic motion shall be applied to the battery having an amplitude of 0,8 mm, with a total maximum excursion of 1,6 mm. The frequency shall be varied at the rate of 1 Hz/min between the limits of 10 Hz and 55 Hz. The entire range of frequencies (10 Hz to 55 Hz) and return (55 Hz to 10 Hz) shall be traversed in (90 ± 5) min for each mounting position (direction of vibration).

Table 5 – Test sequence

Step 1 Record open circuit voltage in accordance with 5.2.

Steps 2 to 4 Apply the vibration specified in 6.2.2.3 in the sequence in Table 5.

Step 5 Rest battery for 1 h.

Step 6 Record examination results.

Requirements

There shall be no leakage, no fire and no explosion during this test.

Climatic-temperature cycling

6.2.2.4

An undischarged battery shall be tested under the following procedure.

Temperature cycling procedure (see 1) to 7) below and/or Figure 2)

1) Place the batteries in a test chamber and raise the temperature of the chamber to

(70 ± 5) °C within t1 = 30 min.

2) Maintain the chamber at this temperature for t2 = 4 h.

3) Reduce the temperature of the chamber to (20 ± 5) °C within t1 = 30 min and maintain

at this temperature for t3 = 2 h.

4) Reduce the temperature of the chamber to (–20 ± 5) °C within t1 = 30 min and maintain

at this temperature for t2 = 4 h.

5) Raise the temperature of the chamber to (20 ± 5) °C within t1 = 30 min.

6) Repeat the sequence for a further nine cycles.

7) After the 10th cycle, store the batteries for seven days prior to examination.

Requirements：

There shall be no fire and no explosion during this test.

Incorrect installation (four batteries in series)

6.3.2.1

Four undischarged batteries of the same brand, type and origin shall be connected in

series with one reversed (B1) as shown in Figure 3. The circuit shall be completed for 24 h

or until the battery case temperature has returned to ambient.

The resistance of the inter-connecting circuitry shall not exceed 0,1 Ω.

Requirements

There shall be no fire and no explosion during this test (see NOTE 2 of 6.3.2.1b)).

External short circuit

6.3.2.2

An undischarged battery shall be connected as shown in Figure 4. The circuit shall be

completed for 24 h or until the battery case temperature has returned to ambient. The

resistance of the inter-connecting circuitry shall not exceed 0,1 Ω.

Requirements

There shall be no fire and no explosion during this test.

Overdischarge

6.3.2.3

One undischarged battery (C1) is discharged under the application or service output test condition, with the highest MAD value  (expressed in time units), as defined in IEC 60086-2 until the on-load voltage falls to (n x 0,6 V) where n is the number of cells in the battery. Then, three undischarged batteries and one discharged battery (C1) of the same brand, type and origin shall be connected in series as shown in Figure 5. The discharge shall be continued until the total on-load voltage falls to four times (n x 0,6 V).

The value of the resistor (R1) shall be approximately four times the lowest value from the resistive load tests specified for that battery in IEC 60086-2. The final value of the resistor (R1) shall be the nearest value to that prescribed in 6.4 of IEC 60086-1.

Requirements

There shall be no fire and no explosion during this test.

Free fall test

6.3.2.4

Undischarged test batteries shall be dropped from a height of 1 m onto a concrete surface. Each test battery shall be dropped six times, a prismatic battery once on each of its six faces, a round battery twice in each of the three axes shown in Figure 6. The test batteries shall be stored for 1 h afterwards.

Requirements

There shall be no fire and no explosion during this test.
