UL 9540 2023 New Version Kusintha
Mtengo wa UL95402023 New Version Amendment,
Mtengo wa UL9540,
▍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.

▍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.
Pa Juni 28, 2023, muyezo wamabatire osungira mphamvu ANSI/CAN/Mtengo wa UL9540:2023:Standard for Energy Storage Systems and Equipment ikupereka kukonzanso kwachitatu. Tidzasanthula kusiyana kwa tanthawuzo, kapangidwe ndi kuyesa.Kwa Battery Energy Storage System (BESS), malo otsekedwa ayenera kukumana ndi UL 9540A Unit Level test.Gasket ndi zisindikizo zimatha kutsatira UL 50E / CSA C22.2 No. 94.2 kapena kutsatira UL 157 kapena ASTM D412.Ngati BESS imagwiritsa ntchito mpanda wachitsulo, mpandawo uyenera kukhala zinthu zosapsa kapena zigwirizane ndi UL 9540A unit.ESS mpanda uyenera kukhala wolimba komanso wosasunthika. Izi zitha kutsimikiziridwa ndikupambana mayeso a UL 50, UL 1741, IEC 62477-1, UL 2755, ISO 1496-1 kapena milingo ina. Koma kwa ESS yochepera 50kWh, kulimba kwa mpanda kungawunikidwe kudzera mu standard.Software yomwe imatha kukwezedwa patali iyenera kutsatira UL 1998 kapena UL60730-1/CSA E60730-1 (Mapulogalamu a Gulu B) ESS yokhala ndi mabatire a lithiamu-ion ya 500 kWh kapena kupitilira apo iyenera kuperekedwa ndi njira yolumikizirana ndi machenjezo akunja (EWCS) kuti adziwitse ogwiritsa ntchito za vuto lomwe lingakhale lotetezeka. Alamu yamawu iyenera kukhala yogwirizana ndi UL 464/ ULC525. Kuchuluka kwa mawu kwa ma alarm alamu sayenera kupitirira 100 Dba.ESS yokhala ndi zamadzimadzi, kuphatikiza ESS yokhala ndi zoziziritsa zomwe zili ndi zoziziritsa zamadzimadzi, ziyenera kuperekedwa ndi njira zina zodziwira kutayikira kuti ziwone kutayika kwa choziziritsa. Kutulutsa koziziritsa komwe kwazindikirika kumapangitsa kuti pakhale chizindikiro chochenjeza ku ESS yowunikira ndi kuwongolera dongosolo ndipo adzayambitsa alamu ngati aperekedwa.
