2000Hz Battery Test Equipment UN38.3 EV Battery Vibration Testing

Lithium-ion batteries are the most common battery type used for electric vehicles. During their lifespan, these batteries undergo various vibrations and temperature changes. Several test standards have been developed to simulate long-term environmental effects on these batteries across different size levels (cell, module, pack).

• SAE J2380: Simulates the effect of driving 100,000 miles on battery packs and modules with random vibration profiles.
• SAE J2464: Evaluates abuse tolerance for cells and battery packs, including thermal shock cycling and shock vibration tests.
• IEC 62660-2: Specifies reliability and abuse testing for electric vehicle lithium-ion cells, including random vibration and mechanical shock tests.
• UN 38.3: Simulates vibration loads experienced by lithium batteries during transportation with swept sine tests.

Sine Vibration: Changes according to a sine function over time, used to test resistance to resonance frequency vibration.

Random Vibration: Irregular time-domain waveform that better reflects real-world vibration conditions during transportation and use.

Mixed-mode Vibration: Superposition of sine and random vibrations for comprehensive testing scenarios.
