How to test a battery pack?

The test can be performed in two ways, which refer to ISO 6469-1-2019 . In the first one, water is allowed to enter into the battery pack (which is considering the battery pack applies forced air cooling as thermal management) but no serious harm should be triggered.

Is GB 38031 a standard for battery testing?

Due to the appearance in 2020, the latest standard in China (GB 38031) is not included. Robertson et al. investigate battery testing protocols and corresponding performance parameters (such as capacity, energy resistance or power) from China (QC/T 743) and the U.S. Advanced Battery Consortium (USABC).

What GB standards do battery cells need to meet?

It should be noted that, when there is no GB regulation, the GB/T or QC/T series standards would also be cited by the government regulations as a mandatory requirement. At present, the referred standards that battery cells need to meet include GB/T 31,484 , GB/T 31,486 and GB 38031 .

Are battery testing methods harmonized?

An approach for the comparison of testing methods in standards & regulations is proposed. A deep-dive analysis on safety testing methods regarding harmonization potentials is conducted. Guidelines for the harmonization of battery testing methods and test execution are derived. Lithium-Ion batteries contribute a key technology for electric vehicles.

How many gb38031 tests were conducted in 2020?

According to the research results published on United Nations Electric Vehicle Safety 20th Web Meeting, Chinese researchers conducted 59 tests in 2020 using either heating or nail penetration accordance with the GB38031.
