Kemgbe afọ 25^thAug., 2008, Korea Ministry of Knowledge Economy (MKE) mara ọkwa na National Standard Committee ga-eduzi ọhụrụ mba n'otu asambodo akara - aha ya bụ KC akara dochie Korean Asambodo n'oge n'etiti Jul. 2009 na Dec. 2010. Electrical Ngwa nchekwa asambodo nchekwa. Atụmatụ (KC Asambodo) bụ iwu amanyere na atụmatụ nchekwa nchekwa nke na-achịkwa onwe ya dịka iwu njikwa nchekwa ngwa eletrik siri dị, atụmatụ nke kwadoro nchekwa nke nrụpụta na ire ere.

Ọdịiche dị n'etiti asambodo amanyere iwu na njikwa onwe(afọ ofufo)nkwenye nchekwa:

Maka nchekwa nchekwa nke ngwa eletriki, a na-ekewa asambodo KC n'ime asambodo nchekwa amanyere na nke onwe ya (nke afọ ofufo) dị ka nhazi nke ihe ize ndụ nke ngwaahịa.A na-etinye isiokwu nke akwụkwọ ikike na ngwa eletriki nke usoro ya na usoro nke ngwa nwere ike ime ka ọ bụrụ ihe dị mkpa. nsonaazụ dị oke egwu ma ọ bụ ihe mgbochi dịka ọkụ, ọkụ eletrik.Ọ bụ ezie na a na-etinye ihe ndị metụtara asambodo nchekwa onwe (nke afọ ofufo) na ngwa eletriki nke usoro ya na usoro ntinye ya enweghị ike ịkpata nsonaazụ dị egwu ma ọ bụ ihe mgbochi dịka ọkụ, ujo eletrik.Na enwere ike igbochi ihe egwu na ihe mgbochi site na ịnwale ngwa eletriki.

▍ KC asambodo maka batrị lithium

1. Ọkọlọtọ asambodo KC maka batrị lithium:KC62133:2019
2. Ogo ngwaahịa nke asambodo KC maka batrị lithium

A. Batrị lithium nke abụọ maka ojiji na ngwa mbugharị ma ọ bụ ngwaọrụ mbughari

B. Cell adịghị n'okpuru akwụkwọ KC ma ọ bụ ọrịre ma ọ bụ gbakọta na batrị.

C. Maka batrị eji na ngwaọrụ nchekwa ike ma ọ bụ UPS (ike na-adịghị akwụsị akwụsị), na ike ha nke karịrị 500Wh karịrị oke.

D. Batrị nke njupụta ike ya dị ala karịa 400Wh/L na-abata n'ogo asambodo kemgbe 1^st, Eprel 2016.
