6 FAQs about [The role of vibration test for new energy batteries]

What is battery vibration testing?

The focus of this blog is to address battery vibration testing. Vibration testing is pivotal for an effective battery pack or module design, therefore, several independent standards for vibration testing have been developed by various governing bodies. Here is a list of some of the standards for vibration testing

What is a test battery?

The test battery is instrumented to detect resonances as well as a loss of electrical isolation, abnormal battery voltages, and abnormal temperature conditions. UN 38.3 (2021): Requirements for the safe transportation of lithium metal and lithium-ion batteries, including altitude, temperature, vibration, shock, and impact/crash testing.

How does a vibration test work?

The vibration test simulates the typical vibrations with transporting batteries with a swept sine test over 3 hours for each of the three possible perpendicular mounting positions. The shock test applies 3 positive and 3 negative direction half-sine shocks in each of the three perpendicular mounting positions (totaling to 18 shocks).

What are the different types of vibration tests for batteries?

Here is a list of some of the standards for vibration testing Random vibration, shock, and sinusoidal or sine sweep tests are the most common vibration tests for batteries. The main differences between the standards are the type of excitation, the vibration profiles, and the frequency range.

What are the different EV battery test standards?

What is a shock vibration test?
