UL 9540 2023 Isichibiyelo Senguqulo Entsha
I-UL95402023 New Version Amendment,
I-UL9540,
▍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.
I-ETL:Isifinyezo se-American Electrical Testing Laboratory. Yasungulwa ngo-1896 ngu-Albert Einstein, umsunguli waseMelika.
UL:Ukulinganisa kwenkampani Underwriter Laboratories Inc.
▍Umehluko phakathi kwe-cTUVus, i-ETL ne-UL

▍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.
Ngomhla zingama-28 kuJuni 2023, indinganiso yesistimu yebhethri yesitoreji samandla ANSI/CAN/I-UL9540:2023:I-Standard for Energy Storage Systems kanye Nezisetshenziswa zikhipha isibuyekezo sesithathu. Sizohlaziya umehluko wencazelo, ukwakheka kanye nokuhlola.Ngohlelo Lwesitoreji Samandla Ebhethri (i-BES), indawo evalekile kufanele ihlangabezane nokuhlolwa kwe-UL 9540A Unit Level.I-Gasket nama-seals angahambisana ne-UL 50E/CSA C22.2 No. 94.2 noma athobele I-UL 157 noma i-ASTM D412.Uma i-BESS isebenzisa indawo ebiyelwe ngensimbi, leyo ndawo evalekile kufanele ibe izinto ezingashi noma ithobelane ne-UL 9540A unit.ESS Indawo ebiyelwe kufanele ibe nokuqina okuthile nokuba lukhuni. Lokhu kungafakazelwa ngokuphumelela ukuhlolwa kwe-UL 50, UL 1741, IEC 62477-1, UL 2755, ISO 1496-1 noma amanye amazinga afanayo. Kodwa nge-ESS engaphansi kuka-50kWh, ukuqina kwendawo ebiyelwe kungahlolwa ngaleli zinga.Isofthiwe engathuthukiswa ukude kufanele ihambisane ne-UL 1998 noma UL60730-1/CSA E60730-1 (Isofthiwe Yekilasi B)ESS enamandla wamabhethri e-lithium-ion. okungama-500 kWh noma ngaphezulu kufanele kuhlinzekwe ngohlelo lokuxhumana oluyisixwayiso lwangaphandle (EWCS) ukuze kunikezwe isaziso kusengaphambili kubasebenzisi mayelana nenkinga yokuphepha engaba khona.Ukufakwa kwe-EWCS kufanele kubhekise ku-NFPA 72. I-alamu ebonakalayo kufanele ihambisane ne-UL 1638. I-alamu yomsindo kufanele ihambisane ne-UL 464/ ULC525. Izinga eliphezulu lomsindo lama-alamu omsindo akufanele lidlule ku-100 Dba.ESS equkethe uketshezi, okuhlanganisa i-ESS enamasistimu okupholisa aqukethe okokupholisa uketshezi, izohlinzekwa ngezindlela ezithile zokutholwa kokuvuza ukuze kuqashwe ukulahleka kokupholisa. Ukuvuza okupholile okutholiwe kuzoholela esignali eyisixwayiso kusistimu yokuqapha nokulawula ye-ESS futhi kuzoqalisa i-alamu uma ihlinzekiwe.
