▍Kodi PSE Certification ndi chiyani?

PSE (Product Safety of Electrical Appliance & Material) ndi njira yovomerezeka yotsimikizira ku Japan. Imatchedwanso 'Compliance Inspection' yomwe ndi njira yovomerezeka yofikira pamsika ya zida zamagetsi. Chitsimikizo cha PSE chimapangidwa ndi magawo awiri: EMC ndi chitetezo chazinthu komanso ndi lamulo lofunikira lalamulo lachitetezo ku Japan pazida zamagetsi.

▍ Certification Standard ya mabatire a lithiamu

Kutanthauzira kwa METI Ordinance for Technical Requirements(H25.07.01), Appendix 9, Lithium ion secondary mabatire

▍Chifukwa chiyani MCM?

● Malo oyenerera: MCM ili ndi malo oyenerera omwe angakhale ndi miyezo yonse yoyezetsa ya PSE ndi kuyesa kuyesa kuphatikizapo kukakamiza mkati mwafupifupi dera ndi zina. Imatithandiza kupereka malipoti osiyanasiyana oyesera mosiyanasiyana mumtundu wa JET, TUVRH, ndi MCM etc. .

● Thandizo laukadaulo: MCM ili ndi gulu la akatswiri 11 akatswiri aukadaulo okhazikika pamiyezo ndi malamulo oyezetsa a PSE, ndipo amatha kupereka malamulo atsopano a PSE ndi nkhani kwa makasitomala mwatsatanetsatane, mwatsatanetsatane komanso mwachangu.

● Ntchito zosiyanasiyana: MCM ikhoza kupereka malipoti mu Chingerezi kapena Chijapani kuti ikwaniritse zosowa za makasitomala. Pakadali pano, MCM yamaliza ntchito zopitilira 5000 za PSE zamakasitomala onse.

Chitetezo cha njira yosungiramo mphamvu ndizovuta kwambiri. Monga chimodzi mwazinthu zofunika kwambiri zosungira mphamvu zamagetsi, chitetezo cha batri la lithiamu-ion ndikofunikira kwambiri. Monga kuyesa kwamphamvu kwa kutentha kumatha kuwunika mwachindunji kuopsa kwa moto wopezeka m'makina osungiramo mphamvu, mayiko ambiri apanga njira zoyeserera zofananira pamiyezo yawo kuti awone chiwopsezo cha kuthawa kwamafuta. Mwachitsanzo, IEC 62619 yoperekedwa ndi International Electrotechnical Commission (IEC) imafotokoza njira yofalitsira kuti iwunikire chikoka cha kuthawa kwa cell; Chinese national standard GB/T 36276 amafuna matenthedwe akuthawa kuwunika kwa selo ndi matenthedwe kuthawa mayeso a batire gawo; US Underwriters Laboratories (UL) imasindikiza miyezo iwiri, UL 1973 ndi UL 9540A, zonse zomwe zimayesa kuthawa kwa kutentha. UL 9540A idapangidwa mwapadera kuti iwunike kuchokera pamiyezo inayi: cell, module, cabinet, ndi kufalitsa kutentha pamlingo woika. Zotsatira za mayeso othamangitsidwa ndi kutentha sizingangoyang'ana chitetezo chonse cha batri, komanso kutilola kuti timvetsetse msanga kuthawa kwa maselo, ndikupereka magawo ofanana ndi mapangidwe a chitetezo cha maselo omwe ali ndi chemistry yofanana. Gulu lotsatira la kuyesa kwazomwe mukuthawa kutentha ndikuti mumvetsetse mawonekedwe a kuthawa kwamafuta pagawo lililonse ndi zida zomwe zili muselo.
Gawo 3 ndi gawo la kuwonongeka kwa electrolyte (T1 ~ T2). Kutentha kukafika 110 ℃, electrolyte ndi electrode negative, komanso electrolyte palokha zidzachitika angapo kuwola anachita, kubala kuchuluka kwa mpweya. Mpweya womwe umatulutsa mosalekeza umapangitsa kuti kukakamiza mkati mwa selo kuchuluke kwambiri, kufika pamtengo wotsitsimula, ndipo makina otulutsa mpweya amatseguka (T2). Panthawi imeneyi, mpweya wambiri, electrolytes ndi zinthu zina zimatulutsidwa, zomwe zimachotsa kutentha, ndipo kutentha kumawonjezeka kumakhala koipa.
