UN38 3 Vibration test is an important safety certification that must be undertaken during the transportation of lithium batteries and their components. The purpose of this test is to simulate the vibration shock that the battery may encounter during actual transportation and evaluate its safety performance to ensure safety during transportation. Lithium products are classified as Class 9 dangerous goods and can pose a risk of explosion, fire and loss of life if not designed or handled properly.
Perform an extensive lithium battery vibration test procedure according to UN 38.3. Our state-of-the-art electro dynamic shaker simulates common transport frequencies to predict how the battery will respond to real-world conditions.
During the vibration test, we placed the battery in a logarithmic scan between 7 Hz and 200 Hz for a period of 15 minutes, over 3 hours. We can repeat the test in all three perpendicular installation locations.
The battery and battery are firmly fixed on the platform of the electro dynamic shaker, and will not deform the battery, thus faithfully transmitting the vibration. The vibration should be a sinusoidal waveform, scanned logarithmically between 7 Hertz and 200 Hertz, and traversed to 7 Hertz in 15 minutes. Repeat this cycle 12 times at each of the three vertical battery mounting locations for a total of 3 hours. One of the vibration directions must be perpendicular to the end face. Logarithmic frequency scanning should be different for batteries and batteries with a total mass of up to 12l kg (batteries and small batteries), and for batteries with a total mass of more than 12kg (large batteries). For batteries and small batteries: Start at 7hz and maintain a peak acceleration of 1g until you reach 18hz. The amplitude is then maintained at 0.8 mm(with a total offset of 1.6 mm) and the frequency is increased until a peak acceleration of 8 gn(about 50 Hz) occurs. The peak acceleration of 8gn is then maintained until the frequency increases to 200hz. For large batteries: the peak acceleration from 7hz to 1gn is maintained at 18hz, the amplitude then remains at 0.8mm (with a total shift of 1.6 mm), the frequency increases until a peak acceleration of 2gn (about 25 Hz) occurs, and then the peak acceleration of 2gn is maintained until the frequency increases to 200hz.
Our experts measure the battery’s mass and voltage before and after testing to identify signs of mechanical failure or impaired function, using a range of non-destructive testing and inspection methods such as computed tomography (CT) to identify microscopic faults and damage. Whether the battery passes the vibration test or not, our experts provide a thorough and comprehensive analysis to help the customer take the next step.
