1. What is IEC62133 certification?

At present, according to the relevant regulations of IATA's "Dangerous Goods Regulations", airlines are not limited to mobile phone batteries, laptop batteries, walkie-talkie batteries, camera batteries that are rechargeable lithium batteries, including but not limited to transported separately or together with equipment. , remote control toy batteries and other products have made relevant testing regulations, of which IEC62133 is an international standard for batteries.

2. What items are tested in IEC62133 certification?

1. High simulation test

Under the conditions of pressure≤11.6kPa and temperature of 20±5℃.

2. Thermal test

Under the conditions of 75±2℃ and -40±2℃, the high and low temperature impact test is carried out, the storage time at the extreme temperature is more than 6h, the high and low temperature conversion time is less than or equal to 30min, the impact is 10 times, and the room temperature (20±5℃) is stored for 24h, The total duration of the trial is at least one week.

3. Vibration test

Complete a reciprocating logarithmic sweep sinusoidal vibration from 7Hz to 200Hz within 15min, and complete 12 vibrations in three-dimensional direction within 3h;

4. Impact test

150g, 6ms or 50g, 11ms half-sine shock, 3 times for each installation direction, 18 times in total;

5. External short circuit test

Short-circuit at 55±2°C and external resistance <0.1Ω, and the short-circuit time lasts for 1h after the battery temperature returns to 55±2°C.

6. Crash test

A 9.1kg weight is dropped on the battery with a 15.8mm round rod from a height of 61±2.5cm, and the surface temperature of the battery is detected.

7. Overcharge test

Under the condition of twice the maximum continuous charging current and twice the maximum charging voltage, overcharge the battery for 24h.

8. Forced discharge test

The battery is connected in series with a 12V DC power supply, and is forced to discharge at the maximum discharge current.
