Example of testing an EV car battery using a small 6-degree-of-freedom vibration system

  • Automotive parts
  • Vibration test case study

Test overview

■ Purpose

This test system is a small 6-degree-of-freedom vibration test system newly constructed at the Advanced Technology Centre for Environmental Testing (Uenohara).
Testing will be possible at two locations, including the existing equipment already located at Osaka Test Lab.
We use tests in Osaka and Uenohara depending on the type of product being tested, offering a wide range of options in terms of delivery time and cost.

■ EUT

EV battery: approx. W 1500 x L 2100 x H 300 mm/approx. 600 kg

Test condition

Test method: Actual waveform reproduction test
Excitation direction: Simultaneous excitation in 3 directions (6DOF)
Exam time: about 100 hours

Feature

6-degree-of-freedom vibration testing system allows for more reproducible testing of real environmental loads.
