Embodiment 1

[0060] Cut the AGM separator samples with a diameter of Φ60mm. The samples with a thickness of less than 1.5mm are grouped with 5 pieces, and the samples with a thickness greater than or equal to 1.5mm are grouped with 4 pieces. Cut 3 groups for use; The AGM separator samples in the first group are perforated first, and the holes are evenly perforated on the end surface of the entire sample. The interval between adjacent holes is not greater than 2mm, and the hole diameter is not greater than 0.2mm. When piercing, the above-mentioned AGM separator can be used to test the wet rebound ability under different compressions, and multiple sets of steel needles are evenly installed on the pressure-applying end, and the lifting assembly is used to complete the piercing operation of the sample. Afterwards, use a drying room to dry at 105±2°C for more than 1 hour. During the drying process, the drying room should maintain a negative pressure state, and finally take it out to the cooling ...

Description

technical field [0001] The invention belongs to the technical field of accumulators, and more specifically relates to a device and method for testing the resilience of AGM separators in wet state under different compression amounts. Background technique [0002] VRLA batteries are widely used in UPS power supply, electric bicycles, energy storage power stations, start-stop cars and other fields due to their poor liquid design, small self-discharge, maintenance-free, and flexible installation positions. [0003] Batteries have different requirements for battery performance due to different uses. The tightness of battery assembly, that is, the compression requirements for AGM separators vary greatly. The compression of separators ranges from 20% to 30%. The performance of controlled sealed batteries, especially the battery life, has a greater impact. [0004] AGM glass fiber separator is an important part of the valve-regulated lead-acid battery, and the performance of the se...
