NgoJuni 28^th2023, indinganiso yesistimu yebhethri yesitoreji samandlaANSI/CAN/UL 9540:2023:Okujwayelekile Kwezinhlelo Nezisetshenziswa Zokugcina Amandla ikhipha isibuyekezo sesithathu. Sizohlaziya umehluko wencazelo, ukwakheka nokuhlolwa.

Izincazelo ezingeziwe

• Engeza incazelo ye-AC ESS
• Engeza incazelo ye-DC ESS
• Engeza incazelo Yeyunithi Yendawo yokuhlala
• Engeza incazelo Yesistimu Yokulawula Isitoreji Samandla (ESMS)
• Engeza incazelo Yesistimu Yokuxhumana Yesexwayiso Sangaphandle (EWCS)
• Engeza incazelo ye-Flywheel
• Engeza incazelo Yendawo Engahlalwa kuyo
• Engeza incazelo Yesibuyekezo Sesofthiwe Esikude

Isidingo Esisha esakhiweni

• Ngohlelo Lwesitoreji Samandla Ebhethri (BESS), indawo evalekile kufanele ihlangabezane nokuhlolwa Kweleveli Yeyunithi ye-UL 9540A.
• I-Gasket nama-seals angathobela i-UL 50E/CSA C22.2 No. 94.2 noma ahambisane ne-UL 157 noma i-ASTM D412
• Uma i-BESS isebenzisa indawo evalekile yensimbi, leyo ndawo evalekile kufanele ibe izinto ezingashi noma ithobelane neyunithi ye-UL 9540A.
• Indawo evalekile ye-ESS kufanele ibe nokuqiniswa okuthile kanye nokuqina. 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.
• Iyunithi ye-ESS yokungena enokuvikelwa kokuqhuma nokukhipha umoya.
• Isofthiwe engathuthukiswa ukude kufanele ihambisane ne-UL 1998 noma UL60730-1/CSA E60730-1 (Isofthiwe Yekilasi B)
• I-ESS enamandla wamabhethri e-lithium-ion angu-500 kWh noma ngaphezulu kufanele ihlinzekwe ngohlelo lokuxhumana oluyisixwayiso lwangaphandle (EWCS) ukuze kunikezwe isaziso kusenesikhathi kuma-opharetha ngenkinga 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 i-100 Dba.
• I-ESS equkethe uketshezi, okuhlanganisa i-ESS enamasistimu okupholisa aqukethe okokupholisa uketshezi, izohlinzekwa ngezindlela ezithile zokutholwa ukuvuza ukuze kuqashwe ukulahleka kwesipholisa. Ukuvuza okupholile okutholiwe kuzoholela esignali eyisixwayiso kusistimu yokuqapha nokulawula ye-ESS futhi kuzoqalisa i-alamu uma ihlinzekiwe.
• Izinga lomsindo elisuka ku-ESS phakathi nokusebenza kufanele likhawulelwe esisindweni sesikhathi samahora angu-8 esingu-85 Dba. Ingahlolwa nge-29 CFR 1910.95 noma indlela efanayo. Uhlelo olunamazinga omsindo angaphezu kwalo mkhawulo luzonikezwa amalebula neziyalezo eziyisixwayiso. (Lokhu kusayeqa imikhawulo yomyalelo wemishini we-EU, ongu-80 Dba)
• I-Electrochemical ESS enezindawo ezivalekile ezihlanganisayo lapho kunethuba lokuhlangana kwegesi evuthayo ngaphakathi kwendawo ebiyelwe kusukela esimweni esingavamile njengokubaleka kokushisa nokusabalalisa, izohlinzekwa ngokuwohloka noma ukuvikela ukuqhuma ngokuvumelana ne-NFPA 68 noma i-NFPA 69. Ukuvikelwa akukona okudingekayo uma ukuhlolwa okuhambisana ne-UL 9540A ngokuhlaziywa kwengozi yokudemeka kukhombisa ukuthi ukugcwala kwegesi evuthayo elinganiswa phakathi nokuhlolwa kuhlala kungaphansi kuka-25 % LFL. Kumakhabhinethi/izindawo ezivalekile ze-ESS, ukuvikela ngaphandle kwalokho okuphawuliwe kungasetshenziswa uma kunqunywa ukuthi ikhabhinethi/i-enclosure ye-ESS yakhelwe ukuvikela ngempumelelo ezingozini ngenxa yokugxila okuvuthayo lapho i-ESS ihlolwe ngokuhambisana nezinga leyunithi noma Ukuhlolwa Kwezinga Lokufaka le-UL 9540A.
• I-ESS equkethe izinto eziqinile eziyingozi (okungukuthi i-pyrophoric noma izinsimbi ezisebenza emanzini) izoklanywa futhi ifakwe ngokuvumelana ne-NFPA 484.

Izinto ezintsha zokuhlola ezingeziwe

Lukuhlolwa kwe-akage

Ku-ESS esebenzisa isipholile esiwuketshezi noma equkethe uketshezi oluyingozi, uketshezi oluyizikhathi ezingu-1.5 (uma luhlola ngoketshezi) umfutho ophakeme wokusebenza noma izikhathi ezingu-1.1 zokucindezela okukhulu kokusebenza (uma ukuhlolwa komoya womoya) kufanele kufakwe ezingxenyeni eziqukethe uketshezi. Ngeke kube khona ukuvuza ezingxenyeni.

1.Eumthelela wokuvala

Beka indilinga yensimbi enobubanzi obungu-50.8 mm nesisindo esingu-535 g ukusuka ekuphakameni okungu-1.29 m ebusweni besampula.

Misa i-sphere yensimbi ngentambo bese ushwibeka njenge-pendulum, wehle ngobude obuqondile obungu-1.29m ukuze uthinte ubuso obuseceleni.

Ngemuva kwemithelela, i-DUT izohlolwa i-Dielectric Voltage Withstand Test. I-DUT izohlolelwa izimpawu zokuqhekeka noma zokulimala. Ngeke kube khona umonakalo endaweni ebiyelwe ongaholela engozini efana nokuchayeka kwezingxenye eziyingozi noma kubangele ukuwohloka kwe-dielectric.

2.Amandla angaguquki endaweni ebiyelwe

Lokhu kuhlolwa kwenziwa nge-electrochemical ESS eyenzelwe izicelo zokuhlala noma izinhlelo zokusebenza okungezona ezokuhlala ezingaphansi noma ezilingana no-50 kWh. Isampula kufanele imelane namandla angu-250N ± 10N ngethuluzi lokuhlola eliyindilinga elingu-30 mm ububanzi. Ukuhlolwa kufanele kwenziwe ngokushintshana kuye phezulu, phansi nasezinhlangothini kwendawo ebiyelwe. I-DUT izokwenziwa i-Dielectric Voltage Withstand Test. Ngeke kube khona umonakalo noma ukuphuka kwe-dielectric.

3.Ukucindezeleka kwesikhunta

Lokhu kuhlola okokuvikela okubunjiwe kwe-polymeric material. Beka isampula kuhhavini ogcinwe ezingeni lokushisa elifanayo okungenani elingu-10℃ (18 ℉) ngaphezu kwezinga lokushisa eliphezulu lendawo ebiyelwe elinganiswa phakathi nokusebenza okuvamile futhi ugcine amahora angu-7. Ngemuva kokususwa kuhhavini, isampula kufanele ifakwe ngaphansi kokuhlolwa kwe-dielectric voltage ukumelana. Akufanele kube nokuqhekeka kwendawo ebiyelwe noma i-dielectric.

Imvelo yokuzamazama komhlaba

Kukhona okokusebenza okungeke kuhlolwe ngokoqobo ngokuhlola kuphela ngenxa yobukhulu bempahla. Kulezo zimo, kungase kudingeke ukuba kwenziwe inhlanganisela yokuhlaziya nokuhlola izingxenye zesistimu. Le ndlela ichazwe ku-IEEE 344.

Okusha Kwengeziwe ISIHLOMELO

Faka isijobelelo G - CLEAN AGEN Direct MJOVA ABATTERY RACK COOLANT SYSTEM UNITS

I-CLEAN AGEENT – Isicishamlilo esingabambi ngogesi, esingaguquki, noma esinegesi esingashiyi insalela lapho sihwamuka.

I-DIRECT MJOVU I-BATTERY RACK COOLANT SYSTEM UNIT – Izingxenye ezihlonziwe ezihlanganiswa zibe yisistimu yokukhishwa kwe-ejenti ehlanzekile ngokusebenzisa amapayipi angaguquki namabhobho ngenjongo yokupholisa amamojula ebhethri ukuze kukhawulwe ukusakazeka okushisayo ngaphakathi kwendawo yokubeka ibhethri/isistimu yokugcina amandla ebhethri .

Lokhu kungabuye kubhekwe njengohlelo lokucisha umlilo lwe-ESS

Cumyalo:

Ukusebenza

1. Ukuhlolwa kokuhlanganiswa komenzeli ohlanzekile (UL/ULC 2166)
2. Qala ukukhipha ukuhlolwa
3. Ukuhlolwa kwesistimu yokupholisa umjovo oqondile - Ukuhlolwa komlilo ngezikali ezinkulu (Izinga leyunithi noma ukuhlolwa kwezinga lokufaka ku-UL 9540A)
