Amaphrojekthi ezentengiselwano, ezezimboni, nezinga lensiza aya ngokuya athembela ezinhlelweni zokugcina amandla ebhethri (BESS) ukuze alinganisele isidingo segridi futhi agcine amandla avuselelekayo. Kodwa-ke, ukukhetha isisetshenziswa esifanele sokugcina amandla kuhlanganisa ukuzulazula imininingwane eyinkimbinkimbi yezobuchwepheshe kanye nemithetho eqinile yokuphepha. Ukuhlola isitifiketi se-BESS ngaphambi kokuthengwa kwempahla kubalulekile ukuze kuncishiswe ubungozi bokubaleka, kuqinisekiswe ukuphepha kukagesi, nokwanelisa iziphathimandla zendawo ezinegunya lokulawula (AHJs).

Lo mhlahlandlela uchaza okukhulu Izitifiketi ze-BESS nokuthi yini abathengi okufanele bayiqinisekise ngaphambi kokukhetha isixazululo sokugcina amandla.

Okuthathwayo Okubalulekile

• Qonda Amazinga E-BESS Abalulekile:I-UL 1973 kanye ne-IEC 62619/63056 yekheli lokuphepha kwebhethri, i-UL 9540 ihlanganisa ukuphepha okuhlanganisiwe kwe-ESS, i-NFPA 855 ilawula ukuphepha kokufakwa, futhi i-UN 38.3 ikhuluma ngokuhlolwa kokuthutha kwebhethri ye-lithium.
• Hlukanisa Isitifiketi Ekuhloleni:I-UL 9540A iyindlela yokuhlola yokusabalalisa umlilo oshisayo, hhayi isitifiketi somkhiqizo ozimele. Imibiko yayo isekela ukuhlolwa kwengozi yomlilo kanye nokuhlelwa kokufaka.
• Qinisekisa Ukuthobelana Ngaphambi Kokuthenga:Abathengi kufanele bahlole izitifiketi eziqondene nemodeli ethile, imibiko yokuhlolwa esebenzayo, ububanzi besitifiketi, kanye nezidingo zegridi yesifunda ukuze baqinisekise ukuthi i-BESS ekhethiwe ihlangabezana nezidingo eziqondene zokuphepha nemithetho yephrojekthi ethile.

Kungani Isitifiketi Se-BESS Sibalulekile Kubathengi Besitoreji Samandla?

Isitifiketi se-BESS sisiza abathengi ukuthi bahlole ukuphepha kwemishini, ukuhambisana kokulawula, kanye nokulungela kwephrojekthi. Inikeza ubufakazi obubhaliwe bokuhambisana nezidingo ezichaziwe, okuyenza ibe yingxenye ebalulekile yokuhlolwa kobuchwepheshe nokukhetha abahlinzeki.

1. Ukuqinisekisa Ukuphepha kanye Nokunciphisa Ubungozi

Ukubaleka okushisayo kanye namaphutha kagesi kubangela izingozi ezinkulu ekufakweni kwe-lithium-ion ephezulu umthamo. Izitifiketi ze-BESS ezifanele zinikeza ubufakazi bokuthi izingxenye ezihloliwe noma amasistimu ahlolwe ukuphepha ngaphansi kwezimo ezithile. Kuye ngezinga elisebenzayo, lokhu kuhlola kungase kubhekane nezingozi zikagesi, ukuziphatha okushisayo, ukuphepha kwemishini, nemisebenzi yokuvikela.

2. Ukuthobela Umthetho kanye Nemvume

Iziphathimandla zendawo kanye nezicishamlilo zidinga imibhalo eqinisekisiwe yokuthobela imithetho ngaphambi kokunikeza izimvume zokufaka. Izisetshenziswa ezingahlangabezani nezimfuneko zokuphepha ezisebenzayo zingase zibhekane nobunzima bokuvumela, ukuhlolwa okwengeziwe, noma ukukhathazeka okuhlobene nomshwalense. Ukuqinisekisa izitifiketi ezifanele nemithetho yendawo kusenesikhathi kusiza abathengi ukuthi babone izikhala zokuthobela imithetho ngaphambi kokufakwa kwezinto zokusebenza.

3. Ukuvikelwa Kwezezimali Nokusebenza

Ukuqinisekiswa kusenesikhathi kwamadokhumenti okuphepha kuvikela abathengi ekubambezelekeni okungalindelekile kwephrojekthi nasezinkokhelweni zokuhlola ezingahleliwe. Ukukhetha okokusebenza okunamadokhumenti afanele okuthobela kungasekela ukubuyekezwa kokuxhunywa kwegridi, ukuhlolwa komshwalense, kanye nokuxhasa ngezimali ukukhuthala okufanele, kuyilapho kunciphisa ingcuphe yokubuyekezwa kobuchwepheshe okwengeziwe noma ukubambezeleka kwephrojekthi.

Yiziphi Izitifiketi Namazinga E-BESS Abalulekile?

Izindinganiso zokuphepha zilawula izendlalelo ezihlukene zephrojekthi yokugcina amandla. Ithebula lokuqhathanisa elingezansi ligqamisa ububanzi kanye nomsebenzi oyinhloko wezinga ngalinye elikhulu lamazwe ngamazwe.

1. UL 1973: Ukuphepha Kwebhethri Enganyakazi

I-UL 1973 icacisa izidingo zokuphepha zamabhethri asetshenziswa endaweni yokugcina amandla emile, amandla asizayo emoto, nezinhlelo zokusebenza zesitimela sikagesi esincane. Ibhekana nezingozi ezifanele zikagesi, zemishini, zemvelo, nezinye zokuphepha. Kubathengi be-BESS, isitifiketi se-UL 1973 sinikeza ubufakazi bokuthi umkhiqizo webhethri oshiwo uhloliwe kwaqhathaniswa nezimfuneko zokuphepha ezisebenzayo, kodwa asiqinisekisi isitifiketi sesistimu ephelele yokugcina amandla.

2. I-UL 9540: Qedela Ukuphepha Kwesistimu Yokugcina Amandla

I-UL 9540 iyindinganiso yokuphepha yezinhlelo nemishini yokugcina amandla. Ihlola ukuphepha kwe-ESS edidiyelwe, okuhlanganisa izingxenye zebhethri ezisebenzayo, okokusebenza kokuguqula amandla, amasistimu okulawula, imisebenzi yokuvikela, kanye nokusebenzisana kwakho ngaphakathi kokucushwa kwesistimu okuhloliwe. Akufanele kudidaniswe ne-UL 9540A, ehlinzeka ngendlela emisiwe yokuhlola izingozi zokusakaza umlilo obalekayo esikhundleni sokuqinisekisa i-ESS ephelele.

3. I-UL 9540A: Ukuhlolwa Kokusakazwa Komlilo We-Thermal Runaway

I-UL 9540A iyindlela yokuhlola esezingeni, kunesitifiketi somkhiqizo esizimele. Ihlola ukusakazeka komlilo obalekayo kanye nezingozi ezihlobene kumasistimu okugcina amandla ebhethri kumaleveli ahlukene okuhlola, okuhlanganisa iseli, imojula, iyunithi, namazinga okufaka, njengoba kusebenza.

Ukuhlola kuhlola ukuziphatha kokushisa okushisayo, ukuphuma kokushisa negesi, ukusakazeka komlilo, kanye nezingozi ezingaba khona zokuthungela, ukuwohloka kwefulegi, noma ukuthungela kabusha. Iziphathimandla zokuphepha komlilo nabahleli bephrojekthi basebenzisa imiphumela ukuhlola ubungozi bokufaka, amabanga okuhlukaniswa, kanye nezidingo zokuvikela umlilo.

4. I-IEC 62619 kanye ne-IEC 63056: I-International Lithium Battery Safety

I-IEC 62619:2022 icacisa izidingo zokuphepha nokuhlolwa kwamaseli e-lithium esibili namabhethri asetshenziswa ezinhlelweni zezimboni, okuhlanganisa amasistimu okugcina amandla amile, izinsiza zikagesi ezingaphazamiseki, nezinye izinhlelo zokusebenza zezimboni.

I-IEC 63056:2020 ikhuluma nokuphepha komkhiqizo wamaseli e-lithium yesibili namabhethri asetshenziswa ezinhlelweni zokugcina amandla kagesi ane-voltage ephezulu ye-DC engu-1,500 V.

Lawa mazinga ahlinzeka ngezinkomba zokuphepha ezihambisanayo zamabhethri e-lithium asetshenziswa ezinhlelweni zokugcina amandla kagesi.

5. I-NFPA 855 kanye ne-UN 38.3: Amazinga Wokufaka kanye Nokuhamba

I-NFPA 855 iyindinganiso yokuphepha yokufaka yamasistimu okugcina amandla amile, kunezinga lesitifiketi somkhiqizo. Isungula izidingo zokunciphisa izingozi ezihlobene ne-ESS, okuhlanganisa indawo, ukufakwa, ukuhlukaniswa, ukuvikelwa komlilo, nezinye izinyathelo zokuphepha ezisebenzayo.

I-UN 38.3 isho izimfuneko zokuhlola ezokuthutha kwebhethri le-lithium ngaphansi kwe-United Nations Manual of Tests and Criteria. Ihlanganisa izigaba zokuhlola eziyisishiyagalombili: I-T.1 Altitude Simulation, T.2 Thermal Test, T.3 Vibration, T.4 Shock, T.5 External Short Circuit, T.6 Impact/Crush, T.7 Overcharge, kanye ne-T.8 Forced Discharge. Ukuhlola okusebenzayo kuncike ohlotsheni nasekumisweni kweseli ye-lithium noma ibhethri. Ukuhlolwa kwe-UN 38.3 kusekela ukuthobela ukuphepha kwezokuthutha kodwa akuhlanganisi isitifiketi esijwayelekile sokuphepha komkhiqizo.

Ingabe Izidingo Zokugunyazwa Kwe-BESS Zihluke Kanjani Ngemakethe?

Okulindelekile kwesitifiketi kuyehluka ezindaweni zamazwe ngamazwe. Abathengi kufanele bahlole imithetho yemakethe eqondiwe kusenesikhathi esigabeni sokuthenga ukuze bagweme izithiyo ezibizayo zokuthobela imithetho.
