In the evolving world of transportation, Electric Vehicles (EV) have become a superior choice for consumers, resulting in a rising demand for automobile manufactures to produce safe, reliable, and efficient EV’s. Along with the higher production volume comes rigorous standards for testing, specifically when it comes to the crucial components, such as battery packs. Vibration testing of EV batteries ensures they are safe under various road conditions, optimized for performance in regards energy efficiency, power delivery, and lifespan, and reliable when subject to real-world conditions.
Crystal Instruments Vibration Controller Systems can be configured from 8 to 512 input channels and a 160 dB dynamic range. Crystal Instruments have dedicated experts to assist with testing and system setup, along with precision VCS software to customize various vibration test types (Sine, Random, Shock, Sine on Random, Random on Random, and many more) and robust Post Analyzer software for post-testing data analysis.
Special features of Crystal Instruments systems for EV battery testing:
High Frequency Range (256 kHz sampling)
High Dynamic Range (160 dB) from our patented dual ADC design.
CAN bus with alarm/abort limits for measuring internal temperature and humidity.
Variable Sampling Rate for high channel count systems with different input measurements (Acceleration, Temperature, Strain, etc.)
Multi-Spectrum Resolution with varying spectral resolution from low to high frequencies.
With Crystal Instruments systems, engineers can be confident that their EV batteries are tested to meet safety, performance, and reliability standards.
Recently, Crystal Instruments provided two high-channel count systems to an automotive manufacturer, each equipped with 96 input channels from ten Spider-80Hi front end cards (80 Voltage/IEPE inputs sampled simultaneously at 204.8 kHz) and two Spider-80Ti front end cards (16 temperature measurement inputs with a temperature range from -200ᵒ C to 850ᵒ C).
Crystal Instruments provides all profiles required for single axis and multiple axis vibration tests. In this installation, the control software provided control for single axis shakers and two comprehensive Gold software packages for single axis vibration testing.
The Gold software package includes:
Non-acceleration control
In addition to the Gold package, the system included FFT spectral analysis software and time recording data acquisition for 128 inputs.
