Mayeso a CellThermal Runaway and Analysis of Gas Production,
Mayeso a Cell,
▍Kodi cTUVus & ETL CERTIFICATION ndi chiyani?
OSHA (Occupational Safety and Health Administration), yogwirizana ndi US DOL (Department of Labor), ikufuna kuti zinthu zonse zogwiritsidwa ntchito kuntchito ziyenera kuyesedwa ndi kutsimikiziridwa ndi NRTL zisanagulitsidwe pamsika. Miyezo yoyezetsa yogwiritsidwa ntchito ikuphatikiza miyezo ya American National Standards Institute (ANSI); Miyezo ya American Society for Testing Material (ASTM), Miyezo ya Underwriter Laboratory (UL), ndi miyezo ya bungwe lozindikiritsa fakitale.
▍OSHA, NRTL, cTUVus, ETL ndi UL matanthauzo ndi ubale
OSHA:Chidule cha Occupational Safety and Health Administration. Ndi mgwirizano wa US DOL (Department of Labor).
Mtengo wa NRTL:Chidule cha Nationally Recognized Testing Laboratory. Ndiwoyang'anira kuvomerezeka kwa labu. Mpaka pano, pali mabungwe oyesa 18 omwe avomerezedwa ndi NRTL, kuphatikiza TUV, ITS, MET ndi zina zotero.
cTUVus:Chizindikiro cha TUVRh ku North America.
Mtengo wa ETL:Chidule cha American Electrical Testing Laboratory. Idakhazikitsidwa mu 1896 ndi Albert Einstein, woyambitsa waku America.
UL:Malingaliro a magawo a Underwriter Laboratories Inc.
▍Kusiyana pakati pa cTUVus, ETL & UL

▍Chifukwa chiyani MCM?
● Thandizo Lofewa kuchokera ku qualification ndi teknoloji:Monga labu yoyesa mboni ya TUVRH ndi ITS ku North America Certification, MCM imatha kuyesa mitundu yonse ndikupereka ntchito zabwinoko posinthana ukadaulo maso ndi maso.
● Thandizo lolimba laukadaulo:MCM ili ndi zida zonse zoyezera mabatire akuluakulu, ang'onoang'ono komanso olondola (mwachitsanzo, galimoto yamagetsi yamagetsi, mphamvu zosungiramo zinthu, ndi zinthu zamagetsi zamagetsi), zomwe zimatha kupereka ntchito zonse zoyezera batire ndi ziphaso ku North America, zomwe zimakwaniritsa miyezo. UL2580, UL1973, UL2271, UL1642, UL2054 ndi zina zotero.
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 kwa kuthawa kwamafuta ndikuti mumvetsetse mawonekedwe a kuthawa kwamafuta pagawo lililonse ndi zida zomwe zili muselo. Gawo 3 ndilo gawo la kuwonongeka kwa ma 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 wopumira, ndipo makina otulutsa mpweya amatseguka (T2). Panthawi imeneyi, mpweya wambiri, electrolytes ndi zinthu zina zimatulutsidwa, zomwe zimachotsa kutentha, ndipo kutentha kumawonjezeka kumakhala koipa.
