KC 62619 Comes Into Force & The Portable Outdoor Energy Storage Supply Into Control

On March 20, 2023, the Korean Academy of Technology and Standards (KATS) issued a new bulletin 2023-0027 to implement the new standard KC 62619 for energy storage batteries, which is effective immediately, while the old KC 62619 standard will be abolished one year after the bulletin’s effective date.

 Compared to the 2019 edition of KC 62619, the main changes in the new edition of the standard are:

  • 1. Alignment of the definition of terms with international standards;
  • 2. The scope of application is expanded to include mobile energy storage equipment in the control, and it is more clearly stated that portable outdoor energy storage power sources are also in scope; the scope of application is revised to more than 500Wh and less than 300kWh;
  • 3. Chapter 5.6.2 supplementing the requirements for battery system design;
  • 4. Addition of the requirement for system lock;
  • 5. Addition of EMC requirements;
  • 6. Addition of a thermal spread test procedure for thermal runaway triggered by laser.

Compared with the international standard IEC 62619:2022, the main changes in the new edition of the standard are:

  • 1. Scope of coverage
  1. In the international standard, the scope of application is industrial batteries;
  2. KC 62619:2022 clarifies that its scope applies to energy storage batteries and specifies that mobile/fixed energy storage batteries, power supplies for camping and mobile electric vehicle chargers are within the scope of the standard.
  • 2. Sample quantity requirements
  1. In clause 6.2, the IEC standard requires R for the number of samples (R is 1 or more);
  2. In the new version of KC 62619, 3 samples are required for each test of electric cells and 1 sample is required for battery systems.
  • 3. The new version of KC 62619 has added the content of Appendix E, which refines the assessment method for battery systems below 5kWh.
  • 4. The old version of KC 62619 will be abolished one year after the effective date of the announcement.
