Kedu ihe bụ KC?

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.

▍ Onye nwere ike itinye akwụkwọ maka asambodo KC:

Ndị mmadụ niile ma ọ bụ ndị mmadụ n'otu n'otu ma n'ụlọ na mba ọzọ na-arụ ọrụ n'ichepụta, mgbakọ, nhazi nke ngwa eletriki.

▍ Atụmatụ na usoro nke asambodo nchekwa:

Tinye akwụkwọ maka asambodo KC nwere ụdị ngwaahịa enwere ike kewaa n'ụdị isi na ụdị usoro.

Iji dokwuo anya ụdị ụdị na imewe nke ngwa eletriki, a ga-enye aha ngwaahịa pụrụ iche dịka ọrụ ya dị iche iche si dị.

▍ 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.

▍ Gịnị kpatara MCM?

● MCM na-emekọ ihe ọnụ na ụlọ ọrụ ndị Korea, dị ka KTR (Korea Testing & Research Institute) ma nwee ike ịnye ngwọta kachasị mma na arụmọrụ dị elu na ọnụ ahịa bara uru nye ndị ahịa site n'oge ụzọ, usoro nyocha, asambodo. ọnụ ahịa.

● Enwere ike nweta asambodo KC maka batrị lithium nwere ike ịchaji site n'itinye asambodo CB wee gbanwee ya ka ọ bụrụ asambodo KC. Dịka CBTL n'okpuru TÜV Rheinland, MCM nwere ike ịnye akụkọ na asambodo nke enwere ike itinye maka ntụgharị nke asambodo KC ozugbo. Enwere ike belata oge ndu ma ọ bụrụ na itinye CB na KC n'otu oge. Kedu ihe ọzọ, ọnụahịa metụtara ya ga-adị mma karị.

Nchekwa nke usoro nchekwa nchekwa ike bụ nchegbu nkịtị. Dịka otu akụkụ dị oke mkpa nke sistemu nchekwa ike, nchekwa batrị lithium-ion dị mkpa karịsịa. Dị ka thermal runaway test nwere ike nyochaa ozugbo ihe ize ndụ nke ọkụ na-eme na sistemụ nchekwa ike, ọtụtụ mba emepụtala ụzọ nnwale kwekọrọ na ụkpụrụ ha iji chọpụta ihe ize ndụ nke ịgba ọsọ ọkụ. Dịka ọmụmaatụ, IEC 62619 nke International Electrotechnical Commission (IEC) nyere na-akọwapụta usoro mgbasa ozi iji nyochaa mmetụta nke okpomọkụ na-agba ọsọ nke cell; Ọkọlọtọ mba China GB/T 36276 chọrọ nyocha ịgba ọsọ nke thermal nke cell na thermal runaway module nke batrị; US Underwriters Laboratories (UL) na-ebipụta ụkpụrụ abụọ, UL 1973 na UL 9540A, ha abụọ na-enyocha mmetụta ịgba ọsọ ọkụ. Emebere UL 9540A ka ọ nyochaa site na ọkwa anọ: cell, modul, kabinet, na mgbasa ọkụ na ọkwa nrụnye. Nsonaazụ nke thermal runaway test nwere ike ọ bụghị naanị na-enyocha n'ozuzu nchekwa nke batrị, ma na-ekwe ka anyị ngwa ngwa na-aghọta thermal runaway nke mkpụrụ ndụ, na-enye ndị yiri paramita maka nchekwa imewe nke sel ndị yiri kemistrị. Ndị na-esonụ data ule maka thermal runaway bụ maka gị ịghọta àgwà nke thermal runaway na nke ọ bụla na ihe ndị dị na cell.
