I/ Production process

III/ safety performance testing

1. High-low temperature pressure:

Change the temperature between 80±5℃ and 0℃, and simulate 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 adjustement.  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 transportion.

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. 

FAQ

1-Q/ Should a protective plate be added to a lithium-ion battery pack? 

A/ Yes. To prevent an over discharge of the battery

2-Q/ What is the advantage of the protective plate on the battery

A/ To protect the battery through an overcharge and over current process.

3-Q/ Is it possible to have a larger capacity for a battery? 

A/The capacity and size of the battery is proportional to the size, the larger the size, the larger the capacity.

4-Q/ What’s a high rate battery?

A/ If the current of the battery is too large or more than 3 C, it requires another battery.

5-Q/ What is the cut-off voltage of a lithium battery?

A/ Based on your product requirements, the battery can be configured accordingly.
