Idatha Yokuhlola Ye-Cell Thermal Runaway kanye Nokuhlaziywa Kokukhiqizwa Kwegesi
Ukuhlola Idatha YeseliI-Thermal Runaway kanye nokuhlaziywa kokukhiqizwa kwegesi,
Ukuhlola Idatha Yeseli,
▍Iyini i-cTUVus & ne-ETL CERTIFICATION?
I-OSHA (Occupational Safety and Health Administration), exhumene ne-US DOL (Umnyango Wezabasebenzi), ifuna ukuthi yonke imikhiqizo ezosetshenziswa emsebenzini kufanele ihlolwe futhi iqinisekiswe yi-NRTL ngaphambi kokuba idayiswe emakethe. Amazinga okuhlola asebenzayo ahlanganisa amazinga e-American National Standards Institute (ANSI); Amazinga e-American Society for Testing Material (ASTM), amazinga e-Underwriter Laboratory (UL), kanye namazinga enhlangano yokuqaphela mutual yefekthri.
▍OSHA, NRTL, cTUVus, ETL kanye nencazelo yamagama e-UL kanye nobudlelwano
OSHA:Isifinyezo Sokuphepha Kwasemsebenzini Nokuphathwa Kwezempilo. Kuyinhlangano ehlangene ye-US DOL (Umnyango Wezabasebenzi).
I-NRTL:Isifinyezo Selabhorethri Yokuhlola Eyaziwa Kuzwelonke. Iphethe ukugunyazwa kwelebhu. Kuze kube manje, kunezikhungo zokuhlola ezivela eceleni eziyi-18 ezigunyazwe yi-NRTL, okuhlanganisa i-TUV, ITS, MET njalonjalo.
cTUVus:Uphawu lwesitifiketi se-TUVRh eNyakatho Melika.

▍Kungani i-MCM?
● Ukusekelwa Okuthambile okuvela kuziqu nobuchwepheshe:Njengelebhu yokuhlola yofakazi ye-TUVRH kanye ne-ITS kusitifiketi saseNyakatho Melika, i-MCM iyakwazi ukwenza zonke izinhlobo zokuhlola futhi inikeze isevisi engcono ngokushintshisana ngobuchwepheshe ubuso nobuso.
● Usekelo oluqinile oluvela kubuchwepheshe:I-MCM ifakwe zonke izinto zokuhlola amabhethri amaphrojekthi amakhulu, amancane futhi anembayo (okungukuthi imoto ephathwayo esebenza ngogesi, amandla okugcina, kanye nemikhiqizo yedijithali), ekwazi ukuhlinzeka ngezinsizakalo zokuhlola ibhethri kanye nezitifiketi eNyakatho Melika, ezihlanganisa izindinganiso. UL2580, UL1973, UL2271, UL1642, UL2054 njalonjalo.
Ukuphepha kwesistimu yokugcina amandla kuyinto evamile. Njengenye yezingxenye ezibalulekile zesistimu yokugcina amandla, ukuphepha kwebhethri ye-lithium-ion kubaluleke kakhulu. Njengoba ukuhlolwa kokubaleka okushisayo kungahlola ngokuqondile ingozi yomlilo oyenzeka kusistimu yokugcina amandla, amazwe amaningi asungule izindlela zokuhlola ezihambisanayo kumazinga awo ukuze kuhlolwe ingozi yokubaleka okushisayo. Isibonelo, i-IEC 62619 ekhishwe yi-International Electrotechnical Commission (IEC) ibeka indlela yokusabalalisa yokuhlola umthelela wokubaleka okushisayo kweseli; Izinga lezwe laseShayina le-GB/T 36276 lidinga ukuhlolwa kokushisa okushisayo kweseli nokuhlolwa kokushisa okushisayo kwemojuli yebhethri; I-US Underwriters Laboratories (UL) ishicilela amazinga amabili, i-UL 1973 kanye ne-UL 9540A, womabili ahlola imiphumela yokushisa okushisayo. I-UL 9540A yakhelwe ngokukhethekile ukuhlola kusuka kumazinga amane: iseli, imojula, ikhabethe, nokusabalalisa ukushisa ezingeni lokufaka. Imiphumela yokuhlolwa kwe-thermal runnaway ayikwazi nje ukuhlola ukuphepha kukonke kwebhethri, kodwa futhi isivumela ukuthi siqonde ngokushesha ukugijima kwamaseli, futhi inikeze imingcele eqhathanisekayo yomklamo wokuphepha wamaseli anamakhemikhali afanayo. Iqembu elilandelayo lokuhlola idatha yokubaleka okushisayo elokuthi uqonde izici zokubaleka okushisayo esigabeni ngasinye kanye nezinto ezikuseli.Isigaba sesi-3 isigaba sokubola kwe-electrolyte (T1~ T2). Lapho izinga lokushisa lifinyelela ku-110 ℃, i-electrolyte kanye ne-electrode engalungile, kanye ne-electrolyte ngokwayo kuzokwenzeka uchungechunge lokusabela kokubola, okukhiqiza inani elikhulu legesi. Igesi eqhubekayo yenza ukucindezela ngaphakathi kweseli kukhuphuke kakhulu, kufinyelele inani lokukhululeka kwengcindezi, futhi kuvuleke indlela yokukhipha igesi (T2). Ngalesi sikhathi, igesi eningi, ama-electrolyte nezinye izinto zikhulula, zisuse ingxenye yokushisa, futhi izinga lokushisa elikhulayo liba libi.
