Ku-1500V, imboni ihlukaniswe ngokusobala yaba abantu abanethemba lokuhle kanye nama-conservatives.Ama-optimist ngokuvamile avela kuma-electronics amandla futhi avame ukubheka izinkinga ngombono wesistimu yamandla;ama-Conservatives amaningi azi okwengeziwe ngamabhethri futhi akholelwa ukuthi ukuphepha kwebhethri ye-lithium kufanele kube okuhamba phambili.
E-China, i-Sungrow iyinkampani yokuqala ukusebenzisa i-1500V ukugcina amandla.Okwenza i-Sungrow Power Supply ingabi namandla ukuthi i-1500V isetshenziswe kabanzi emazweni angaphandle, kodwa ubuchwepheshe obuvuthiwe buye bagxekwa eChina.
Uma sibheka izinhlelo zokugcina amandla ezingu-1500V ezethulwe manje e-China, imiklamo eminingi yasekhaya isekelwe ku-280Ah amabhethri e-lithium iron phosphate square, kodwa amaqembu ephakethe ahlukile komunye nomunye.Basebenzisa i-1P10S, 1P16S, ne-1P20S ngokulandelana.Amandla ephakethe angu-8.96KWh, 14.34KWh, 17.92KWh.
Kuhlale kunezingxabano ezinkulu mayelana nokuthi amaseli ebhethri ohlelo lokugcina amandla abe mkhulu noma abe mancane, futhi izinzuzo kanye nokubi kwakho kokubili kusobala.Ngokungafani nasekhaya, amabhethri e-Samsung SDI kanye ne-LG Chem amabhethri amakhulu aweqili i-120Ah, futhi uTesla ikakhulukazi uthathe izinzuzo zamabhethri amancane ngokwedlulele.
Ngokuvamile, kuba nzima nakakhulu kumabhethri amakhulu ukuze akhiphe ukushisa, futhi kunzima kakhulu ukulawula ukuhambisana kwesistimu yokugcina amandla;lapho amabhethri amancane edinga ukuxhunywa ochungechungeni noma ngokuhambisana ngesikhathi senqubo yokuhlanganisa uhlelo, akunakwenzeka ukuthi i-BMS ne-EMS isampula yonke i-node.Idatha yeseli ngayinye iyaqoqwa, ngakho ukuphathwa kweseli kuba nzima kakhulu futhi izindleko zokuhlanganisa ziphezulu.Ngokuvamile, ukwakhiwa kwamazinga amathathu okuqala ngedatha yemojula kuyamukelwa, futhi idatha eqoqwe yinhlanganisela emibili-kune yidatha yamabhethri amane noma amabhethri amabili, angakwazi ukubonisa idatha yamanje.
”Ngokombono wesakhiwo sezinkampani eziholayo, isisombululo samanje sesistimu yokugcina amandla sisasikhulu kuneseli elilodwa.Ibhethri lamandla enkathi ye-Ningde ngokuyinhloko lingu-280Ah, kanti i-BYD 302Ah izotholakala maduze.”Umholi wezobuchwepheshe wesihlanganisi sesistimu yokugcina amandla engu-1500V Ithi.
Umkhiqizi omkhulu webhethri uthe i-65Ah iwumkhawulo oyisisekelo wemboni yamanje yebhethri.Kubakhiqizi abaningi bebhethri abancane, ulayini womkhiqizo usuqediwe futhi ungakhuphula amandla amanje kuphela ngoxhumo oluhambisanayo lwamaqoqo ebhethri, kodwa lokhu akusewona umzila ojwayelekile.Ngokombono wakhe, inzuzo yamabhethri amakhulu ukuthi awaxhunyiwe ochungechungeni futhi idatha ethengiwe yidatha eyodwa.Ekuphathweni kwe-EMS ne-BMS, ukwethembeka kwedatha kuzoba phezulu.Endabeni yochungechunge olumbalwa noxhumo oluhambisanayo, isistimu izinzile.Ucansi kufanele lube phezulu.
Wasebenzisa "okuphezulu" futhi "okukhulu" ukuze afingqe isiqondiso sokuthuthukiswa kokugcinwa kwamandla, lapho "okuphezulu" kubhekisela kuzinhlelo ze-voltage ephezulu.Ubuchwepheshe bamanje be-1500V buvuthiwe futhi bunamandla okuphromotha ngobuningi;“amakhulu” kubhekiselwa kumabhethri amakhulu amanje embonini, akwaziukwandisa kakhulu umthamo wokugcina.Ukuminyana kwamandla ohlelo lwamandla kuwumkhuba ongenakugwemeka ekukhetheni ukuthuthukiswa kwesistimu.
Kodwa yilokhu kanye izinkampani eziningi ze-BMS ezikhathazeka ngakho.Ngokombono wabo, amabhethri amancane anezinzuzo ezincane futhi i-granularity yesistimu incane, ngaleyo ndlela inciphisa umthelela "womphumela wombhobho" webhethri elilodwa kuqoqo lebhethri kanye nesistimu yonke yokugcina amandla.amathonya.Okubaluleke nakakhulu, ibhethri iyisistimu eyinkimbinkimbi.Ukuthengiswa kwamabhethri amakhulu ane-voltage ephezulu kudinga isikhathi esithile sokuqinisekisa.Akekho umkhiqizi webhethri onikeze idatha efanele okwamanje.Phakathi kwazo, njengoba isikhathi sihamba, kuzoba nochungechunge lwezinkinga eziye zatholakala nezingakatholakali.
U-Li Guohong, umqondisi womugqa womkhiqizo wesikhungo somkhiqizo wesistimu yokugcina amandla ka-Sungrow, ukholelwa ukuthi umzimba webhethri uyisisekelo.I-1500V idinga ukungaguquguquki okuphezulu kwebhethri, kodwa idizayini yesakhiwo sesistimu yokugcina amandla ehlobene nempilo yesevisi yesistimu nayo ibaluleke kakhulu.Ithinta ngokuqondile ukuzinza kwesistimu kanye nembuyiselo ekutshalweni kwesitoreji samandla ngasohlangothini olusha lwamandla.“Uma iseli lingu-50Ah, kuzoba namaseli ambalwa ochungechungeni nokuhambisana.Ubuchwepheshe obuyisisekelo bokusebenzisa amangqamuzana amakhulu bulele ekwakhiweni kwephakethe, okuhlanganisa ukuvumelana kokukhipha ukushisa namaseli, okumele kuqinisekiswe ngokuphindaphindiwe ngokuhlolwa kwesistimu.”
U-Li Guohong wethule ukuthi uma kuqhathaniswa nohlelo lwe-1000V, i-Sungrow yamukela imiqondo emisha nezindlela zokuqinisekisa ukuphepha kohlelo lokugcina amandla angu-1500V:Ukuvikelwa kwesifunda segatsha le-BCP, ukufana kwezinga lokushisa kweseli kulo lonke uhlelo, i-fuse + contactor esikhundleni se-circuit breaker , Ukutholwa kwegesi evuthayo, idizayini yokuvikela ukuphepha, njll.

Uma sibheka ngemuva kwabenzi be-1500V, iningi lalezi zinkampani zinesizinda se-photovoltaic namandla kagesi, futhi zingamakholwa athembekile e-1500V.
Embonini ye-photovoltaic, kusukela ngo-2015, i-voltage engu-1500V isithandwa kakhulu e-China.Kulezi zinsuku, uhlelo lwe-photovoltaic ngokuyisisekelo lubone konke ukushintsha kusuka ku-1000V kuya ku-1500V.Izindleko zesistimu yonke zingasindiswa ngo-0.2 yuan/Wp, oye waba negalelo ekukhuthazeni ukulingana kwe-photovoltaic ku-inthanethi, futhi iyithuluzi lezinkampani ezihamba phambili ze-photovoltaic ukuze ziguqule kabusha.
Ukuthuthukiswa kwe-voltage yama-photovoltaics kuye kwabeka isisekelo esihle sokugcina amandla ezingxenyeni ze-elekthronikhi.Ngo-2017, u-Sungrow wahola ekuqaliseni uhlelo lokugcina amandla angu-1500V futhi waqala ukuthutha ubuchwepheshe be-voltage ephezulu busuka ku-photovoltaics buyiswa endaweni yokugcina amandla.Kusukela lapho, ngaphezu kuka-80% wamaphrojekthi amakhulu okugcina amandla e-Sungrow aqala ukusebenza ezimakethe zaphesheya njenge-United States, i-United Kingdom, neJalimane amukele amasistimu angu-1500V.
Embukisweni we-SNEC ka-2019, u-Kehua Hengsheng wethule isizukulwane esisha sohlelo lokugcina amandla ohlobo lwebhokisi lwe-1500V 1MW/2MWh kanye nomshini ohlanganisiwe we-photovoltaic inverter booster ongu-1500V 3.4MW emhlabeni.
Kusukela ngo-2020, i-Ningde Times, i-Kelu, i-NARI Protection, i-Shuangyili, i-TBEA, ne-Shangneng Electric zikhiphe ngokulandelana imikhiqizo ehlobene yokugcina amandla engu-1500V, futhi lo mkhuba kungenzeka usheshe.
Kumnikazi, into kuphela okudingeka ibhekweisiphi isixazululo esingabizi kakhulu ngaphansi kwesisekelo sokuphepha.
Amabhizinisi aphakathi nendawo okuphehla ugesi okuhlanganisa i-SPIC ne-Huaneng asevele akhombisa futhi aqinisekisa ukuthi kungenzeka yini uhlelo lokugcina amandla angu-1500V.Ngo-2018, i-Yellow River Hydropower ithathe isistimu yokugcina amandla engu-1500V njengohlelo olubalulekile lokuhlolwa endaweni yokubonisa isitoreji samandla, futhi kuzoba ngo-2020. Uhlelo lokugcina amandla angu-1500V lusetshenziswa ngamaqoqo esiteshini samandla okugcina amandla Iphrojekthi ye-UHV.Iphrojekthi ka-Huaneng ye-Mendi e-United Kingdom nayo isebenzisa uhlelo lwe-1500V.
Umhlaziyi we-Bloomberg New Energy Finance ukholelwa ukuthi ukuthi umkhiqizo muhle noma cha udinga ukuqinisekiswa kwemakethe.Uma i-1500V ingadla ingxenye enkulu yemakethe, ingabonisa ukuthi umkhiqizo noma intengo inenzuzo.
Njengezingxabano ze-ternary ne-iron-lithium, ngemuva kwezinkampani eziningi, ikakhulukazi lezo ezinesizinda se-photovoltaic, zibheja kakhulu ku-1500V, kulwela ilungelo lokukhuluma kwezobuchwepheshe.Emehlweni odokotela abaningi be-photovoltaic, ukufaka isitoreji samandla ohlangothini lwe-DC kanye nokwabelana ngama-inverters aneziteshi zamandla we-photovoltaic yizinhloso zabo zokuthuthukiswa kwesikhathi esizayo.
Yiqiniso, imboni enempilo akufanele neze ibe nezwi elilodwa kuphela.Imboni yanamuhla yokugcina amandla isenkathini lapho izindlela eziningi zobuchwepheshe zihlala khona kanye nezimbali eziyikhulu ziqhakaza, futhi iyinkathi egcwele izingxabano.
Futhi lolu hlobo lwengxabano ngokuvamile luwuphawu lwenqubekelaphambili.Bonke ubuchwepheshe abuphelele, futhi izinkampani zidinga ukugcina izinga elithile lokuvuleka.Uma ukuncika endleleni kwakhiwe, lapho abantu behlangabezana nesixazululo esisha sobuchwepheshe, bavame ukusiqhathanisa ngokwemvelo nesimo sabo sengqondo esimisiwe, bese benza isinqumo ngokushesha.
Eminyakeni embalwa edlule, lapho ubuchwepheshe be-photovoltaic monocrystalline busanda kuvela, izinkampani ze-polycrystalline azikwazanga ukuguqula imibono yazo yemvelo, zikholelwa ukuthi i-monocrystalline inezindleko eziphakeme, ukuncipha okuphezulu, futhi "ukusebenza kahle" kwayo kuyidumela eliyize.Ekugcineni, ngaphansi kobuholi buka-Li Zhenguo, uLongi wathatha indlela ehlukile futhi wathatha insimu enkulu endaweni ye-photovoltaic monocrystalline.
Njengoba "ukugcina amandla amasha + amandla" kancane kancane kuba yinjwayelo, ukuvela kwezinhlelo zokugcina amandla kumthamo omkhulu ayikayeki.Ikakhulukazi lapho ingekho indlela yokulawula izindleko, ukumenyezelwa kwenqubomgomo yokufaka isitoreji samandla engeziwe ohlangothini olusha lwamandla kuye kwafaka ingcindezi enkulu emalini engenayo yokutshalwa kwezimali kubathuthukisi bamandla abasha.Indlela yokunciphisa ngempumelelo izindleko zesistimu yokugcina amandla futhi uthuthukise ukusebenza kahleukukhiqizwa kwamandla kuseyikusasa lokugcina.Isihloko esiwumgogodla wokuthuthukiswa kwemboni yamandla.
Abanye abahlaziyi bakholelwa ukuthi ukuze kuxazululwe lezi zinkinga ezimbili ezinkulu, “i-cryptography” isesekusha kwezobuchwepheshe.Amandla kagesi aphezulu angenye yezixhumanisi ezibalulekile zokuqanjwa kabusha kwezobuchwepheshe.Ukuthi i-1500V ingathuthukiswa kabanzi esikhathini esifushane kuncike ekutheni imboni ingafinyelela yini isihlukanisi esivamile kakhulu ngokusebenza kobuchwepheshe, ukuphepha, impilo kanye nezindleko.
