Imithambo Yemisebenzi Yebhathari Yelithiyamu Kuzindawo Zokugcina Umqondo Wemisebenzi

Kukhona ukuguqula kusheshelayo kwimisebenzi yokugcina umqondo emhlabeni wonke, ngokuthi iibhathari zelithiyamu zihlala zisiza, ukuphakama kwemisebenzi yezindlela zokuphatha umqondo nesikhungo sokuphatha umqondo, njengoko kufuneka kakhulu ukusobala kwemithambo yokuqinisa umqondo. Ichemistri yokuqinisa umqondo eyinkimbinkimbi kakhulu manje iyilithiyamu-iron-phosphate (LiFePO ₄) eyodwa ephendula i-lead-acid futhi nezinye iichemistri zelithiyamu. Izinto ezintathu zokuvamile zilandelayo ziyizindlela ezikhombisa imisebenzi yokugcina umqondo yebhathari yelithiyamu.

1. Ukuphakama Kwemisebenzi YeliFePO₄ Kwizindawo Zokugcina Umqondo Zasekhaya Nasezindawo Zokusebenza Ngokomthetho

LiFePO ₄iibhathari zimanje ziyachoseni kumisebenzi yokugcina umqondo esekhaya nasezindawo zokusebenza ngokomthetho. Iziphumo zabo ngaphandle kwe-lead-acid nasezinye iibhathari zelithiyamu (NMC — nickel-manganese-cobalt) ziyabonakala zingcono:

Ubuciko: LiFePO ₄iyisitabili kakhulu kusukela kuzo zonke izinkinga zokuphakama kwesikhathi, futhi akukho isibonelo sokuphakama kwesikhathi, ngakho ke kusetshenziswa emasimini, emaphoyinti wokuthenga, kanye nemithombo yezindlu zokusebenza.

Isikhathi eside sokusebenza: amaqhina angu-4,000–6,000 ekugcineni kwesikhathi sokugcina ngu-80%, kulandela amaqhina angu-1,000–2,000 ye-NMC kanye namaqhina angu-300–500 we-lead-acid.

Isivinini esikhulu sokusebenza: ukugcina ngu-80–100% kulandela ukugcina ngu-50–60% we-lead-acid.

Kwemithombo yezindlu, abahlali bamasimini bavumelanisa i-LiFePO ₄amabhatteri nesolar ephakathi kwemifula yezindlu ukuze bafanele ngokwezimali kanye nokubhala izinkinga zokungena kwe-grid. Amaphoyinti wokuthenga, amahotela, kanye nemithombo yezindlu zokusebenza emithombo yezindlu yezokusebenza ibhatteri ye-LiFePO4 ukuze zinikeze ukugcina kwe-peak, ukunciphisa ukulwa kwe-demand, kanye nokunika umthelela wokusebenza. Lezi zinhlobo zezinhlobo zazisemthethweni kakhulu ngaphandle kokuthuthukisa ngokwezimali ngoba ubude bezimali be-LiFePO₄ buhlelwe ngaphezu kwe-70% ngeminyaka eyisihlanu edlule.

2. Ukugxilwa kwe-Lithium Batteries nesolar kanye ne- Izinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo zezinhlobo......

Kukhona umthwalo ophakanyiswa kusukela emasimini amadokumenti okuqondisa izithuthi zokugcina ngokupheleleyo. Izinsiza ezintsha zizisebenzisa izinverter ezihlanganisiweyo ozibonakalisa izigaba zezithuthi, izibhanki zemithwalo nezinkampani zokuhlanganisa nge-grid. Lezi zisistimu ziyasebenza ngokupheleleyo nezimithwalo zelithium ngoba zinezinhlobo zokubhala ezinkulu, ukugcina/ukugcina kusheshile futhi zingakhuluma (CAN bus, RS485, Modbus).

Izindlela zokuhlanganisa eziphakeme kuzoba:

Ukupheleka kwe-round-trip okuphakanyisiwe: Izisistimu zelithium ziyasebenza ngokupheleleyo ngokuphakanyisiwe kwe-92-96% ngaphandle kwezilithium zokubhala (futhi ngokubhala kwesilithium) ukupheleka kuyi-80-85%, okusho ukuthi imithwalo engapheleki yingapheleki.

Ukupheleka kwezikhathi zokuphendula: Izimithwalo zelithium zihlanganisa nezilinganiso zokusebenza ngokusheshile kwe-milliseconds okudingekayo kumashini we-UPS nezisistimu zokuvavanya kwe-grid.

Ukuthuthukisa: Izimithwalo zelithium ezihlanganisiweyo zikuvumela abasebenzi bakwakha ukuthuthukisa ukupheleka ngokuphakanyisiwe ngokuphakanyisiwe kwezidingo zabakhasi.

Kukhona ukuthi emisebenzini yezibalo nezindustria, izitringi zemithambo yezinkokhelo ezingaphansi ziyabuyiselwa ngamaphakathi amakhulu we-lithium (400 V futhi kufika ku-800 V), okunquma ukugcina kwamaphakathi nokuthengiswa kwezinto zokufaka. Abalawuli abakhulu abaningi njenge-Shenzhen Weitu Hongda bavalele ukuthenga amaphakathi amashumi amabili angena ngemithambo emibili ye-MPPT futhi abanako ukulayisha izinkokhelo zezinkokhelo zomkhulu.

3. Izinhlelo Zokuzayo: i-BMS esihlukene, Ukujabulisa Kusuka Emuva, Nokudesigna Kwamaphakathi Okuhlanganisa

Igama lokuqala lokugcina kwezinkokhelo zomkhulu liyakubhekana ngezinhlelo ezintathu zokusebenza:

Amaphakathi Esihlukene Sokugcina Kwezinkokhelo (BMS): Amaphakathi esihlukene ashiyela ukubalwa kwezinkokhelo, ukulawula isikhati, ukubala isimo sokulayishwa (SOC) nokubala isimo sokuphelele (SOH) njengoba nokubala iziphetho zokungafani. Amaphakathi okugcina kwezinkokhelo okuzayo kuzobhekwa ngokuvutha kwezinhlelo zokubala ukuthi zilahleke ukuthi zizame ukubala iziphetho zokungafani kabusha, okuyokugcina isikhathi esingaphezulu kwezindawo zezibalo.

Ukukhokha kwezinye izindawo nokusebenzisa i-cloud ukuphatha: Abathengi be-energize yezindawo zokusebenza bazoba bakhuluma ngokuthi bafuna ukufikelela ngokushesha kwezindlela zokusebenza. Izinkampani zokusebenzisa i-cloud zinakukhokha, ukubhala izinguquko zangaphambili, nokuhlela i-firmware ngendlela engaphandle, okunika umsebenzi wokuphatha ngokwemvelo nokuhlela izikhathi zokucharga/nokudischarge, ngokuxhaswa kwezindlela zokusebenza ngokuthi ziyabhalwa ngokuthi ziyasebenza ngokushesha.

Ukubeka kwe-battery ngokweziqu: I-battery eziphakathi (isibonelo, 5kWh, 10kWh) ezinakugcinwa noma zinakubhekana ngokuphakathi zinakunciphisa ukubeka nokubuyisela. Ukubeka kweziqu kusiza futhi ekuphakanyiseni kwesilinganiso, isitolo sesifunda esincane singaqala ngama-30kWh futhi siphakanye ku-100kWh ngaphandle kokubuyisela izinkampani ezengeziwe. Lokhu kunciphisa izimpilo zokubegina yokuhlanganisa abathengi bezindawo zokusebenza.

Isiphetho

Isifundo se-lithium battery energy storage sibuya kuma-LiFePO ₄ukuchemisha ukuhlinzekisa ukuthembeka nokubagqamisa, ukugxilwa kwe-solar ne-hybrid inverters ngaphandle kokuzimela, futhi i-smart BMS ene-remote monitoring nesiqondiso sesihloko. I-Shenzhen Weitu Hongda Industrial Co., Ltd. yisikole sokuphatha amathuba esikhundla, esinokuthembeka kwe-ISO no-CE, ene-line yezinto ezithile (ups, solar inverters, energy storage, kanye nangakho) eyatholakala ku-zibuyelo zonke zokusebenzisa amandla kubantu abasebantwini, abasekomeshali, nabase-industriyeli emhlabeni wonke. Khulisani namu noma usizame ukuxhumana nathi ukuxoxa ngokusebenza kwakho kwe-energy storage.
