UV Accelerated Aging Chamber Selection Guide

UV accelerated aging chamber: core equipment for power battery durability verification

In the field of power battery manufacturing, material weather resistance is directly related to the reliability of the product throughout its life cycle. The AS series of ultraviolet accelerated aging chambers can reproduce the aging process of materials outdoors for months or even years in a laboratory environment through precise UVA/UVB spectrum simulation and thermal environment control. Taking the aluminum-plastic film of lithium batteries as an example, a 3-hour 70°C ultraviolet irradiation test can obtain molecular chain fracture data equivalent to 2 months of natural exposure, providing a key decision-making basis for material selection.

Demand-oriented selection strategy

Typical scenarios for choosing AS-UV-640

（1） Verify the pure UV aging resistance of battery encapsulation materials in arid regions such as the Middle East

（2） Test 12 sets of 18650 battery shells at the same time (600mm width space is required)

（3） Implementation of ASTM G154 standard single factor aging verification

Necessary conditions for choosing AS-UVIP-2W

（1） Evaluate the comprehensive attenuation of energy storage battery boxes in tropical rainforest environments (ultraviolet rays + high humidity + sudden rain)

（2） Need to simulate the condensation effect caused by the temperature difference between day and night (automatic sprinkler + dark cycle control)

（3） Complies with ISO 4892-3 multi-factor aging test standard

Comparison of key decision points

Redefining the value of equipment

UV accelerated aging chambers are reshaping the quality control system of battery manufacturing:

（1） Risk Prediction : Predict material outdoor failure risk 120 days in advance

（2） Cost control : The cost of a single test is only 1/17 of that of outdoor testing

（3） Standard unification : Establishing a quantifiable weather resistance evaluation benchmark
