Mobile energy storage vehicle battery vibration test

What are the different EV battery test standards?

This post focuses on the vibration and temperature aspects of four well-known EV battery test standards: SAE J2380, SAE J2464, IEC 62660-2, and UN 38.3. Crystal Instruments Spider systems can provide solutions for random, sine, and shock vibration test, as well as temperature control.

How long does the random vibration test last?

The random vibration test profiles are executed in three axes for a duration ranging from 9 minutes to 38 hours. The battery depth of discharge is varied during testing. SAE J2380 (2021): Provides a test procedure for characterizing the effect of long-term, road-induced vibration on the performance and service life of electric vehicle batteries.

What is the duration of the vibration test for lithium-ion batteries?

The vibration test consists of a 3-hour sine sweep in three axes. 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.

What do electric vehicle batteries experience during their lifespan?

During their lifespan, these batteries undergo a variety of vibrations and temperature changes. Lithium-ion batteries are gaining popularity as the most common battery type used for electric vehicles.

What is a test battery?

In the context of electric vehicle testing, a test battery is an instrumented battery designed to detect resonances, loss of electrical isolation, abnormal battery voltages, and abnormal temperature conditions. This is in accordance with UN 38.3 (2021) standards for safe transportation of lithium metal and lithium-ion batteries.

What kind of vibrations can Spider systems provide solutions for?

Crystal Instruments Spider systems can provide solutions for random, sine, and shock vibration test, as well as temperature control. Of the many test standards for EV batteries, this post will specifically focus on the vibration and temperature aspects of four well-known standards: SAE J2380, SAE J2464, IEC 62660-2, and UN 38.3.
