Izindinganiso Zokuphepha Eziphelele Zezinhlelo Ze-EV Ezihlanganisiwe ze-BESS

Impendulo Esheshayo:Uhlelo lokushaja lwe-EV oluhlanganisiwe ne-BESS kumele luhlangabezane nezindinganiso zokuphepha ezihlanganisa ibhethri, uhlelo, kanye nezindinganiso zokushaja: i-UL 9540A (ukuhlolwa komlilo oshisayo), i-UL 1973 / IEC 62619 (ukuphepha kwebhethri), i-IEC 63056 / NFPA 855 (ukufakwa kwesitoreji esingashintshi), kanye ne-UL 2202 / UL 2231 noma i-IEC 61851 (ukuvikelwa kweshaja kanye nabasebenzi), kanye ne-ISO 15118 yokuxhumana okuphephile. Abathengi kufanele baqinisekise isitifiketi emazingeni amathathu: amaseli namamojula aqinisekisiwe, uhlelo lokugcina amandla ebhethri oluqinisekisiwe, kanye nemishini yokushaja eqinisekisiwe enezimpawu zesifunda ezifanele (i-CE, i-UKCA, i-ETL, i-TÜV, noma i-GB/T equivalents). Iziteshi ezakhiwe kulokhu kuhlanganiswa kwe-stack pair yokuphathwa kokushisa okupholile okumanzi, ukuvikelwa kwe-BMS okunezingqimba eziningi, kanye nezindawo zokuvala ezilinganiselwe nge-IP65 ezinokucindezela umlilo, zinciphisa ingozi yokusabalala kokushisa okushisayo ngama-oda amakhulu uma kuqhathaniswa nemiklamo engaqinisekisiwe.

Izinto Ezibalulekile Okufanele Uzicabangele:

• Isitifiketi manje sesiyimfuneko yokuthenga kusengaphambili: izinkampani zomshuwalense, izinsiza zikagesi, kanye nabaqhubi begridi baya ngokuya benqaba izindawo ezingaqinisekisiwe ezihlanganisiwe ne-BESS.
• Ukuphepha kwezinga lebhethri kuncike kumakhemikhali weseli (okuthandwayo yi-LFP), ukwakheka kwemodyuli, kanye nemisebenzi ye-BMS ehlanganiswe yi-UL 1973, IEC 62619, kanye ne-IEC 63056.
• Ukuphepha kwezinga lesistimu — izindawo zokuvala, ukucima umlilo, ukupholisa uketshezi, kanye nokufakwa kwe-NFPA 855 — kunquma ukuthi isehlakalo sokushisa sihlala sivikelwe yini.
• Ukuphepha kwe-charging-interface (UL 2231, IEC 61851, ISO 15118) kuvikela abantu futhi kuvimbela ukulawulwa okunonya kwesiteshi.
• Imephu yesitifiketi enezingqimba ezintathu — ibhethri, uhlelo, kanye nesixhumi esibonakalayo — ivumela opharetha ukuthi baqhathanise abahlinzeki ngobufakazi obungaqinisekiswa esikhundleni sezimangalo zokumaketha.

Kungani Izindinganiso Zokuphepha Ziyisidingo Sokuthenga Esisha

Umqhubi wezindawo zokushaja eNingizimu Yurophu uthenge uhlelo lokushaja lwe-solar-plus-storage "olushintshashintshayo" kumhlinzeki ongabhalisiwe ngesaphulelo esingu-35%. Ezinyangeni eziyisithupha kamuva, i-short-level module circuit yabangela ukukhukhuleka kokushisa okwalimaza amakhabethe amathathu ebhethri aseduze, kwavala indawo amasonto ayisishiyagalolunye, futhi kwabangela isimangalo somshuwalense sokuthi umshayeli wesitoreji sepholisi - owayedinga imibhalo ye-UL 9540A - wenqaba ukukhokha. Indawo yakhiwa kabusha ngemishini eqinisekisiwe cishe kabili kunesabelomali sokuqala.

Le ndaba iphindaphindwa ezimakethe ngoba izinhlelo ze-EV ezihlanganisiwe ze-BESS zigxila amaphrofayili amabili engozi abalawuli ababewaphatha ngokwehlukana: ingozi yomlilo webhethri le-lithium-ion kanye nengozi yokushaja ye-DC enamandla aphezulu. Lokhu kuhlangana yingakho isimo sesitifiketi sihlanganiswe saba uhlaka oluhambisanayo nolunokuhlolwa. Ukulandelela izingozi zomlilo ze-International Energy Agency kanye nemibhalo eminingi yesiqondiso somshwalense manje kuphatha imibiko yokuhlola ye-UL 9540A, uhlu lokuphepha olusezingeni lebhethri, kanye namamaki okuphepha kweshaja njengobufakazi obuncane bokungakwazi umshuwalense. Kumqhubi, umphumela osebenzayo ulula: uma umhlinzeki engakwazi ukukhiqiza izitifiketi zebhethri, uhlelo, kanye neshaja, iphrojekthi ayinakukwazi umshuwalense futhi, ezindaweni eziningana, ayivunyelwe.

Imephu Yezindinganiso Zezinhlelo Ze-EV Ezihlanganisiwe ze-BESS

Izindinganiso ezisebenzayo zihlukaniswe ngokuphelele zibe izikophu ezintathu: ibhethri, uhlelo oluhlanganisiwe, kanye nesixhumi sokushaja. Ithebula elingezansi libonisa amadokhumenti alawula izincazelo zokuthengwa ngo-2026.

Izimakethe zokulethwa kwesifunda zibeka amamaki kazwelonke phezu kwalawa: i-CE ne-UKCA yaseYurophu, i-ETL/UL yaseNyakatho Melika, i-TÜV yezimakethe eziningi zokuthumela kwamanye amazwe, kanye ne-GB/T/CCC yaseShayina. Umhlinzeki othengisa ezifundeni eziningi kufanele akwazi ukukhombisa indinganiso yebhethri esebenzayo (UL 1973 noma i-IEC 62619), indinganiso yokufaka (NFPA 855 yase-US), kanye nendinganiso yokushaja (UL 2202/2231 noma i-IEC 61851-23) yemakethe ngayinye eqondiwe.

Ukuphepha Kwezinga Lebhethri: Amaseli, Amamojula, Namaphakethe

Isitifiketi sezinga lebhethri yilapho kuklanywa khona ingozi yokubaleka kokushisa. Izinqumo ezintathu zokuklama zibusa umphumela.

Ikhemistri.Amaseli e-lithium iron phosphate (LFP) — ikhemistri esetshenziswa yi-MIDA kuyo yonke [umugqa womkhiqizo wokugcina amandla] (https://www.midapower.com/energy-storage-charging-station) — anokushisa kokuqala kokushisa okucishe kube ngu-270 °C, cishe angu-70 °C aphezulu kune-NMC chemistryries, futhi akhipha umoya-mpilo omncane kakhulu ngesikhathi sokubola, okunciphisa ukusabalala komlilo. Yingakho i-LFP isibe ikhemistri ezenzakalelayo yezinhlelo zokusebenza zokushaja ezihlanganisiwe ze-BESS, lapho ibhethri lihlala eduze kwabantu nezimoto.

Ukwakhiwa kwemojuli kanye nephakethe.Ukuhlolwa kokusetshenziswa kabi kwe-UL 1973 kanye ne-IEC 62619 kuhlanganisa ukushaja ngokweqile, i-external short circuit, ukuchoboza, ukushaya, kanye nokushisa okuphezulu. Imojuli idlula kuphela uma i-BMS ibona iphutha, amadivayisi okuvikela aphazamisa i-circuit, futhi ukungenisa umoya kweseli kungangeni kumaseli aseduze. Umbiko oyinhloko wokuhlola abathengi okufanele bawucele umbiko we-UL 9540A, okhombisa ukuthi uma iseli lingena endaweni eshisayo, ukusabalala kuyama ngaphakathi kwemojuli noma endaweni echaziwe kunokuba kusabalaliswe ikhabhinethi kukhabhinethi.

Imisebenzi ye-BMS.Uhlelo lokuphatha ibhethri luyisilawuli sokuphepha: luqapha amandla kagesi, izinga lokushisa, amandla kagesi, kanye nokumelana nokushisa, futhi kumele lusebenze ngaphakathi kwama-milliseconds kusukela ekutholakaleni kwamaphutha. I-IEC 62619 idinga ngokusobala imisebenzi yokuvikela i-BMS okuhlanganisa amandla kagesi angaphezu kwamandla, amandla kagesi angaphansi kwamandla, amandla kagesi angaphezu kwamandla, kanye nokuvala amandla kagesi ngokweqile ngokuziphatha okuphephile. I-BMS eqinisekisiwe iphinde iqophe izehlakalo zamaphutha ukuze kuhlaziywe ngokomthetho ngemva kwezigameko.

Ukuvikelwa Kwezinga Lesistimu: Izindawo Ezivalekile, Ukucindezela Umlilo, kanye Nokuphathwa Kokushisa

Isitifiketi sebhethri singqimba olulodwa kuphela. Uhlelo oluhlanganisiwe — indlela amakhabethe akhiwa ngayo, apholiswa ngayo, futhi abekwa ngayo — lunquma ukuthi umcimbi weseli elilodwa uba yini umlilo omkhulu.

Ukuphathwa kokushisa kuyindlela yokuqala yokuzivikela.Ukupholisa umoya ongasebenzi kahle kwanele ngaphansi kwamandla ebhethri aqhubekayo angaba ngu-30 kW, kodwa umjikelezo womsebenzi wokushaja (ukushaja okuphindaphindwayo kanye nokukhishwa) uqhuba ukukhiqizwa kokushisa okuqhubekayo. Ukupholisa okusebenzayo koketshezi — lapho i-coolant ijikeleza khona ngamapuleti abandayo ngaphansi kwamamojula — kugcina izinga lokushisa kusuka kuseli kuya kuseli lingaphansi kuka-3–5 °C, okuyifasitela lokusebenza elivimbela ukuguga okusheshayo kanye nokwakheka kwezindawo ezishisayo. Izinhlelo ezipholile ngoketshezi nazo zigcina amazinga okushisa aphephile ezimweni ezizungezile ezingama-45 °C+ ngaphandle kokuchitha isikhathi, okubalulekile ezindaweni zokushaja zangaphandle.

Ukuvikelwa kokufakwa kanye nokungena.Amakhabethe e-BESS angaphandle kufanele alinganiswe nge-IP65 endaweni evalekile kagesi (engangeni uthuli futhi evikelwe kumajethi amanzi) kanye negumbi lebhethri elinomoya ongenisa umoya ngokwe-NFPA 855. Ukwakhiwa okumelana nokugqwala (insimbi noma i-aluminium embozwe ngophuphu) kanye nokuphathwa kwekhebula elizinzile le-UV kwandisa impilo yesevisi ezindaweni ezisogwini kanye nezindawo ezisogwadule.

Ukutholwa nokususwa komlilo.I-NFPA 855 inquma ukutholwa kwentuthu, izinga lokushisa, kanye negesi nge-alamu, kanye nesu lokucindezela elihambisana nekhemistri. Kuzinhlelo ze-LFP, ukucindezela i-aerosol kanye ne-clean-agent kuhlanganiswe nokutholwa kwegesi kusenesikhathi kuyindlela engcono kakhulu yamanje; ukukhukhula okusekelwe emanzini kuchazwe lapho amakhodi edinga khona. I-BESS kumele futhi ibe nebanga lokuhlukaniswa kwezakhiwo kanye nemigqa yempahla ngokwe-NFPA 855, noma ngezivimbelo ezilinganiselwe umlilo phakathi kwamakhabethe.

Ukuvikelwa ohlangothini lwegridi.Uhlelo luhlanganisa ukunqanyulwa kwe-DC ne-AC, ukuvikelwa kokukhuphuka, amadivayisi wamanje asele, kanye nokuvikelwa kwamaphutha e-arc endaweni yokuxhuma. Ukuthobela ikhodi yegridi (njenge-IEEE 1547 eNyakatho Melika noma i-EN 50549 eYurophu) kulawula ukuziphatha okulwa nokukhuphuka kweziqhingi kanye nokukhuphuka kwamaphutha okuvikela abasebenzi bomugqa ngesikhathi sokungasebenzi.

Ukuphepha Kokushaja-Isixhumi Esibonakalayo: Ukuvikela Abantu Nedatha

I-interface yokushaja ingeza isizinda sesibili esihlukile sokuphepha: ama-conductor e-DC abukhoma afinyelela ku-1000 V, ugesi ophezulu (kufika ku-500 A+ ezinhlelweni ezipholile ngoketshezi), kanye nokulawula okunenethiwekhi. I-UL 2231 kanye ne-IEC 61851-23 zombili ziqapha ukufakelwa komoya — ishaja iqhubeka nokulinganisa ukumelana nokufakelwa komoya phakathi kwebhasi le-DC nomhlaba futhi ikhubaza ukuphuma ngaphakathi kwama-millisecond uma iwela ngaphansi komkhawulo. Ukutholwa kwephutha lomhlaba, ukukhiya kwesixhumi (i-contactor ayikwazi ukuvala ngaphandle kokuthi ipulaki ihlezi kahle futhi ikhiyiwe), kanye nokuma okuphuthumayo okuphazamisa zombili izindlela zamandla konke kuyimisebenzi ephoqelekile.

Ukuphepha kwe-inthanethi kuyisici sokuphepha esivelayo. I-ISO 15118 Plug & Charge iqinisekisa imoto nge-cryptographic, ivimbela ukuntshontshwa kweseshini; I-OCPP 2.0.1 ingeza ukubethela kwe-TLS, ukuphathwa kwesitifiketi, kanye nezibuyekezo ze-firmware ezisayiniwe, ivala indawo yokuhlasela eyadalula amashaja axhunywe kunethiwekhi ekuqaleni ekulawulweni okukude. Isiteshi esiqinisekisiwe yilesi lapho ukwehluleka kokuxhumana kungeke kuguqule kube ukwehluleka kokulawula amandla.

Imephu Yesitifiketi Esinezingqimba Ezintathu Yabathengi

Amaqembu okuthenga angakwazi ukusebenzisa i-standard stack ngenqubo yokuqinisekisa enezinyathelo ezintathu:

1. Qinisekisa ibhethri.Cela umbiko wokuhlolwa kwe-UL 9540A (hhayi nje isifinyezo), isitifiketi se-UL 1973 noma se-IEC 62619, kanye nemibhalo yokuphepha yokusebenza kwe-BMS yomkhiqizi webhethri. Qinisekisa ikhemistri ye-LFP kanye nokupholisa uketshezi kwezinhlelo ezingaphezu kuka-100 kWh. 2.Qinisekisa uhlelo oluhlanganisiwe.Qinisekisa ukufakwa ohlwini noma isimemezelo sezinga lesistimu esihlanganisa ukuthobela imithetho ye-NFPA 855 (US), i-IEC 63056, ukutholwa/ukucindezela umlilo, isilinganiso se-IP, kanye nokuhambisana nekhodi yokuxhumeka kwegridi emakethe okuqondiwe kuyo. 3.Qinisekisa isikhombikubona sokushaja.Qinisekisa isitifiketi se-UL 2202/2231 noma se-IEC 61851-23, ukwesekwa kwe-ISO 15118 Plug & Charge, izici zokuphepha ze-OCPP 2.0.1, kanye nezimpawu zesifunda (CE/UKCA/ETL/TÜV) ezihambisana nezwe lokuthunyelwa.
