Constant temperature and humidity test chamber for constant humidity and heat test of lithium battery of cellular phone
Constant temperature and humidity test chamber for constant humidity and heat test of lithium battery of cellular phone. In 2021, the global cellular phone market sales will reach US$ 100 million, and it is expected to reach US$ 100 million in 2028. Therefore, the future development potential of lithium-ion batteries for cellular phones is great. However, the development of lithium batteries is inseparable from relevant tests. Below, the editor will briefly introduce the constant damp heat test of lithium batteries for cellular phones.
Damp heat test for cellular phone lithium batteries:
1. Test sample: cellular phone lithium battery
2. Test equipment: constant temperature and humidity test chamber
3. Equipment model: Huanyi Instrument HYH series
4. Reference standard: GB/T 18287 General specification for lithium-ion batteries and battery packs for cellular phones
experiment method:
1. Charge the battery pack according to regulations, put the battery pack in a constant temperature and humidity chamber with a temperature of 40℃±2℃ and a relative humidity of 90%~95% for 48 hours.
2. Take out the battery pack and put it aside for 2 hours at an ambient temperature of 23℃±2℃, and visually inspect the appearance of the battery pack. And discharge with 0.2IA current to the termination voltage, the discharge time should not be less than 3 h.
3. The appearance of the battery pack should be free from deformation, corrosion, leakage, deflation, rupture, fire and explosion.
