III/ safety performance testing
1. High-low temperature pressure:
Change the temperature between 80±5 and 0, and simulate the pressure of 5 ~ 7T while the battery is molded under extreme temperature and pressure conditions.
2. Temperature cycle:
The battery should be placed separately at least 6h at the temperature of (75±2) and (-40±2) with a 30min free temperature adjustment. Put the testing battery in (20±5) after thermal shock ten times and evaluate the sealing integrity and internal electric connection under a rapidly changing temperature condition.
3. Extrusion:
A round bar weighting around 9.1kgs with a diameter of 15.8 mm is placed to fall on the battery surface from 61±2.5cm of height. An evaluation is done to assess situations that may cause internal short circuits, such as possible impacts or crushing during shipping.
4. Needle test:
Using a press machine with a steel needle of 3-3.5mm diameter, the battery is punched at 10-40mm/s speed and there should be no smoke, no fire, and no explosion after pulling it out. This test helps evaluate an
internal short circuit condition in the battery
5. Vibration test:
The battery is fixed on a vibrating table, within 15min from 7Hz ~ 200Hz ~ 7Hz to complete a logarithmic frequency sweep sinusoidal vibration, 3h within three-dimensional direction to complete 12 vibrations, no leakage, no exhaust, no disintegration, no rupture, no fire should be observed. The vibration simulation is to evaluate the risks during transportation.
6. Drop test:
The battery is dropped from a falling height of 1.5m free fall on the concrete, the battery should not catch fire, nor be short-circuited & no leakage should be observed;
Usage of extreme safety is required while testing all batteries.
Packaging: Only the qualified batteries will be packaged for delivery.
