Amabhatari we-lead-acid abayebhekene ngezikhathi eziningi njengokuchaza kwezindawo zokusebenza ngokwesibonelo phakathi kweminyaka eminingi. Kodwa, ngokuphakama kwezimali zokusebenza nokuguqula kwezintechinoloji, amabhatari we-lithium ayaphakamisa kushona amabhatari asezingeni lelo. Uma ubhekene nezindlela zokusebenza ku- I-UPS systems , ukugcina imithwalo noma izimpilo zokusebenza, ukuthenga kweprodukthi akuyiyo indlela esodwa yokubona ngayo ngabaprofeshinali. Kuyinto yokubona ukuthenga kwezinye izinto, ukuphatha kahle kwezinye izinto, nokubaluleka kwezinye izinto ngeminyaka eyadlula. Ngoba ngu-“high tech enterprise” oyathengisa izinkampani zokuthenga kwezinye izinto, u-WTHD uyazi ukuthi kufanele yiziphi izindlela zokuzinikela lezi zinkinga, futhi unazo amatekhnoloji amabili okukhetha ngokulinganayo. Kodwa lapho kufanele sibuye sithintele?
Ukuchazela i-Lithium ne-Batteries ye-Lead-Acid bakuze kusetshenziswa kwezinhlangano
Kungasemva kwe-batteries ye-lead acid, i-batteries ye-lithium zinamahlukahluka amabili okukhetha ngokulinganayo okuhambisana nezinye izinto zokusebenza kwezinhlangano. Kulezi zinhlangano njenge-UPS, i-solar inverter, noma i-energy storage system, lezi zinhlangano ziyisodwa.
Ukukhulu kwe-Energy noma isikhundla: Ibatteri yase-lithium zinamandla okuphakathi phakathi kwe-150 kuya kwe-250Wh/kg, ngakolunye uhlangothi ibatteri yase-lead acid inamandla okuphakathi kuphela phakathi kwe-30 kuya kwe-50Wh/kg. Lokhu kuzosiba kubatteri yase-lithium ukuthumela umandla othile ngemibala emincane kanye nemithubi emincane, okuyisibonelo esikhulu kwezindawo ezingaphakathi kwezindawo ezizimele.
Ukuphakama kweecycle: Ibatteri yase-lithium zinamandla okuphakathi phakathi kwe-3,000 kuya kwe-10,000 cycles, okuphakathi kakhulu kwe-300 kuya kwe-500 cycles yebatteri yase-lead acid. Ukuphakama kwe-Round-Trip: Ibatteri yase-lithium zinamandla okuphakathi phakathi kwe-95 kuya kwe-98%, ngakolunye uhlangothi izinamandla okuphakathi phakathi kwe-80 kuya kwe-85% yebatteri yase-lead acid, okuyisibonelo esikhulu kwebhizinisi ezenza amandla amaningi.
Ukugcina kwe-Depth of Discharge (DoD): Ibatteri yase-lithium ingagcina ku-80-100%. Ukuphakama kwebatteri yase-lead acid kungahleli uma ayigcinanga nge-50%. Lokhu kuzosiba kubatteri yase-lithium ukuthumela amandla amaningi okusebenza ngokufanayo kwezibhalo zebatteri zokubhalwa.
Ukuchaza ukuphakama kwebatteri, ukulondoloza, nokuthengiswa kwesikhundla sokuthengisa
Kweli kule okukhombisa ukuthi kukhona umthwalo wokufuna i-Lithium. Noma ukuthi i-lead-acid ina mali amancane kusukela, isikhundla sokubuyisela ngeminyaka emashumi (TCO) singafanana.
Usuku lwemvume: I-battery yase-Lithium enobunzulu ingathola amaqhina angu-3,000 ku-10,000 futhi ingasebenza ngeminyaka eyi-8 ku-15. Umkhathi wokusebenza kwe-battery yase-lead acid ngu-3 ku-5 iminyaka futhi ina amaqhina angu-300 ku-500. I-system yase-lead-acid ingasebenza ngeminyaka eyi-15 futhi ingadinga ukubuyiselwa kabusha kuma-2 ku-4, ngakho-ke i-system yase-Lithium ingasebenza ngokuphelele.
Ukungena: I-battery yase-lead-acid kufanele ibuyiselwe ngokuphatha ngokuphelele ngokuphatha kwe-voltage, ukuchitha amaphuzu, nokufaka amasimbi. Kufanele kube nesikhumbuzo sokuhlanza ukuze kubhekwe ukuproducwa kwe-hydrogen gas. I-Intelligent Battery Management System (BMS) isinika ubukhulu ukuthi i-battery yase-Lithium ayikho nolwazi lokubuyisela. Kuyasebenza ngokwakho futhi kungakhathalisi ukubuyisela kahle noma ukubuyisela kahle kakhulu, kungavunyelwa izinkampani zokubuyisela ngokuphelele, ngokuphatha ngokuzenzakalelayo ngokusebenzisa i-BMS.
I-Total Cost of Ownership (TCO): Izindleko zokusebenzisa izinhlaka zomkhosi zika-lithium ngemva kwezinsuku eziningi ziyakhula kakhulu uma sibheka izindleko zokubuyisela, umsebenzi wokufaka, izindleko zokususa kanye nezinsuku zokungasebenzi (okuthiwa ngokuvamile ngokuthi Yindleko Yokuqala Yokusebenza (TCO)). Kuma-system ephakanyisiweyo apho kunezinhlaka eziningi, izindleko zokubuyisela izinhlaka zomkhosi zika-lead zingaba ezikhulu. Ngokuphakade kwakho, izindleko zokubuyisela izinhlaka zika-lithium zihlukunyezwa futhi zihlanganiswa ngemva kwezinsuku eziningi, okwenza ukuthi izinhlaka zika-lithium ziyinkululeko engeyona yezindleko ngaphandle kokuphakade kweprodukthi.
Ukukhetha Izinhlaka Zika-lithium BesebaKu-UPS Nezindlela Zokugcina Enerji
Ngaphezu kwezindlela zokubuyisa amandla, izinhlaka zika-lithium zingahambisana nenzuzo eyodwa emisebenzini yokuphatha amandla ngokuphakade, njengokubuyisa amandla ngalokhu kungabikho amandla.
Imisebenzi Yama-UPS: Ngaphezu Kwesindlela Yokubuyisa Amadla Ku-Grid: Kusuka kwe-Backup kuya kumaqondiselo we-Grid: Izinhlayiya ze-Lithium zezindiza ziyabecala izinhlayiya zokusebenza kwemisebenzi yomkhakha. Ngokufanana nezindiza ezingaphezulu, izinhlayiya ze-Lithium zezindiza zingasebenzisa lezi mikhakha kumkhakha njenge-peak shaving nokulungisa ifrekhwensi, okungaba yindlela yokubhukuda imali noma ukunciphisa izindleko zomkhakha. Izinhlayiya ze-Lithium zingasebenziswa njenge-sistema yokuqina okusebenzayo, ngaphandle kwezinhlayiya zokuphatha okungasebenzayo ezisebenzisa i-lead-acid.
Izinhlayiya Zokugcina Imisebenzi Yomkhakha (ESS): I-Lithium yilokho kuphela okuyimfundo esebenzisa kuzo kwezinhlayiya zokugcina imisebenzi yomkhakha (ESS), futhi ziyagcinwa kulezi zinhlayiya zokugcina imisebenzi yomkhakha. Kusiza amakhaya ukugcina imisebenzi yomkhakha eyenziwa ngamandla wezulu futhi abayisebenzisele kumakhakha apho imisebenzi yomkhakha iyadingeka kakhulu, okusiza ukunciphisa izindleko zomkhakha. Ukusebenza kahle kanye nokusebenza kahle kokugcina kanye nokugcina kahle kuyisidingo esibalasekile ukusiza i-Lithium ukwenza lezi zikhathi zokugcina nokugcina ngosuku, okungaba yizinhlayiya zokugcina zokugcina kahle kwe-lead acid.
Lapha Kufanele Ushintele: Isimo Sokuziphatha
Kwakhona, ngabani isikhathi esihle sokuguqula umsebenzi wakho? Uma ubhalisile ukuthola ibhayithari yase-Lithium, kube:
Indawo yakho iyasebenza emizulwini emhlophe , ngoba i-Lithium iyasebenza kahle emizulwini emide.
Udinga isikhathi eside sokusebenzisa (ngeminyaka engu-10 noma ngaphezu kwalokho) futhi awukufuna ukubhekana nezindlela zokusolwa.
Isikhundla nesivinini siyisigaba esiphambili , njengokuthi kumsebenzi omncane, noma emaphoyinti amanqaku.
Ufuna ukunciphisa ukuphatha nokugcina izinkinga zokusebenza.
Isistimu sakho se-UPS sinezindlela zokusebenza ezide fakha ukuthi ibe yisifundo sokusebenza ngokulingana.
Kwesinye isikhathi, kuma-locations engaphansi kwezinye, noma kuma-locations apho izikhathi zokubuyisela zingaphezulu kwezinsitha ezintathu ukuze zintathu nezinsitha ezinhlanu, futhi apho kufanele kwenziwe ukulawula kwamandla, amaphutha e-lead-acid angaba yisifundo esihle kuma-locations apho imali yokuqala ayiphansi kakhulu.
I-WTHD inikeza izinkulungwane zama-lead acid ne-lithium, ngakho-ke unakwakha ukuguqula ngokulingana lapho isikhathi sivame. Kusukela ekubeni kwezinto kuya kuzo zokugcina, i-WTHD inakukusiza ngokufaka kwezinto zokufaka kwezinto (OEM/ODM), futhi inezinkinga zezinto zokusebenza njenge-UPS systems nezinkinga zokugcina amandla. Ukuguqula kuma-lead acid kuma-lithium akuyiyo kuphela ukuguqula kwezinto, kodwa yilokuvakashela okuphambili okukhomba ukuthi ubonakale kakhulu futhi ukuthi ubuyise imali yakho yezinsuku eziningi.
