Ibhetri ye-lithium ephezuluibhetri yokugcina amandla eqaphela i-high-voltage ye-DC yemveliso yenkqubo ngokudibanisa iibhetri ezininzi kuthotho. Ngokukhula kwemfuno yamandla avuselelekayo, kunye nokugxila kwabantu ekuguquleni okukhuselekileyo kunye nokusebenzayo kweenkqubo zamandla elanga, iibhetri ze-lithium eziphezulu ze-voltage ziye zaba sesinye sezisombululo ezithandwa kakhulu zokugcina amandla kwiimarike.
Ngo-2024, inkqubo yokugcina i-high-voltage yendawo yokugcina iyabonakala, inani labavelisi bebhetri yokugcina amandla kunye neempawu ziye zaqalisa iindidi zeebhetri zelanga ze-lithium eziphezulu, ezi bhetri azikho kuphela kumthamo, ubomi bomjikelezo kunye neminye imiba impumelelo ebalulekileyo, kodwa kukhuseleko kunye nolawulo olukrelekrele luyaqhubeka nokuphucula. Kweli nqaku, siza kukubonelela ngesishwankathelo sezona bhetri ze-lithium zibalaseleyo ngo-2024, ukukunceda ukhethe ngconoibhetri yasekhayainkqubo yogcino olulungele iimfuno zakho.
Umgangatho 1: Umthamo webhetri osebenzayo
Umthamo webhetri osebenzisekayo ubhekiselele kubungakanani bamandla onokuthi uwatshaje kwibhetri ukuze usetyenziswe kamva ekhaya. Kuthelekiso lwethu lwe-2024 yeebhetri ze-lithium eziphezulu ze-voltage, inkqubo yokugcina enikezela ngeyona ndawo iluncedo kakhulu yi-Sungrow SBH ibhetri ene-40kWh, ilandelwa ngokusondeleyoBSLBATTMatshisibhokisi HVSibhetri 37.28kWh.
Umgangatho 2: Amandla
Amandla sisixa sombane esinokuhanjiswa yibhetri yakho yeLi-ion nangaliphi na ixesha; ilinganiswa ngeekilowathi (kW). Ngokwazi amandla, unokwazi inani lezixhobo zombane onokuthi uzifake nangaliphi na ixesha. Kwi-2024 high-voltage high-voltage lithium-ion ibhetri yokuthelekisa, i-BSLBATT MatchBox HVS iphinda ivelele kwi-18.64 kW, ngaphezu kokuphindwe kabini njengeHuawei Luna 2000, kunye ne-BSLBATT MatchBox HVS inokufikelela kumandla aphezulu angama-40 kW kwi-5s. .
Umgangatho 3: Uhambo oluya nokubuya ngokuSebenzayo
Ukusebenza kakuhle kohambo lokuya nokubuya kubhekiselele kumlinganiselo phakathi komthamo wamandla owadingayo ukuze utshaje ibhetri kunye nobungakanani bamandla akhoyo xa uyikhupha. Ngako oko kuthiwa "uhambo olujikelezayo (ukuya kwibhetri) kunye nokubuya (ukusuka kwibhetri) ngokufanelekileyo". Umahluko phakathi kwezi parameters zimbini kungenxa yokuba kusoloko kukho ilahleko yamandla ekuguquleni amandla ukusuka kwi-DC ukuya kwi-AC kunye nokuphendukile; Okukhona ilahleko isezantsi, kokukhona ibhetri ye-Li-ion iya kusebenza kakuhle. Kuthelekiso lwethu lwe-2024 yeebhetri ze-lithium eziphezulu ze-voltage, i-BSLBATT MatchBOX kunye ne-BYD HVS ibekwe kwindawo yokuqala nge-96% esebenzayo, ilandelwa yi-Fox ESS ESC kunye ne-Sungrow SPH kwi-95%.
Umgangatho wesi-4: Ukuxinana kwamandla
Ngokuqhelekileyo, ibhetri ekhaphukhaphu kunye nesithuba esincinci esithathayo, ngcono, ngelixa ugcina umthamo ofanayo. Nangona kunjalo, ezininzi iibhetri ze-LiPoPO4 eziphezulu zihlukaniswe kwiimodyuli ezinobukhulu kunye nobunzima obunokuphathwa ngokulula ngabantu ababini; okanye kwezinye iimeko ngumntu omnye.
Ke apha sithelekisa ubukhulu becala ubunzima bobunzima bomthamo webhetri ye-lithium ye-high-voltage nganye, ubuninzi bebhetri yamandla obunzima bubhekisa kubuchule bebhetri ukugcina amandla (ekwaziwa nje ngokuba ngamandla athile), nto leyo engumlinganiselo wamandla ewonke agcinwe kuyo. ibhetri kubunzima bayo bubonke, okt, Wh/kg, ebonisa ubungakanani bamandla anokunikezelwa ngeyunithi yobunzima bebhetri.Ifomula yokubala: ubuninzi bamandla (wh/Kg) = (umthamo * umbane) / ubunzima = (Ah * V)/kg.
Ubuninzi bamandla busetyenziswa njengeparameter ebalulekileyo yokulinganisa ukusebenza kweebhetri. Ngokuqhelekileyo, ubuninzi beebhetri ze-lithium-voltage zamandla ziyakwazi ukugcina amandla amaninzi phantsi kobunzima obufanayo okanye umthamo, ngaloo ndlela unikezela ixesha elide lokuhamba okanye uluhlu lwezixhobo. Ngokubala kunye nothelekiso, siye safumanisa ukuba i-Sungrow SBH inoxinano lwamandla oluphezulu oluyi-106Wh/kg, ilandelwa yi-BSLBATT MacthBox HVS, ekwanamandla obuninzi be-100.25Wh/kg.
Umgangatho wesi-5: Ukukala
I-scalability yenkqubo yakho yokugcina amandla ikuvumela ukuba ukwandise umthamo webhetri yakho ye-Li-ion ngeemodyuli ezintsha ngaphandle kokuphazamiseka xa imfuno yakho yamandla ikhula. Ke ngoko, kubalulekile ukwazi ukuba yeyiphi umthamo wenkqubo yakho yokugcina inokwandiswa ukuya kuyo kwixesha elizayo.
Xa kuthelekiswa neebhetri ze-lithium eziphezulu ze-voltage kwi-2024, i-BSLBATT MatchBox HVS inikezela ngeyona ndlela ininzi kakhulu ngokubhekiselele kumthamo onobungozi, ukuya kwi-191.4 kWh, ilandelwa yi-Sungrow SBH ene-scalable umthamo we-160kWh.
Oku, kuba siqwalasela iibhetri ezinokudityaniswa kwi-inverter enye. Nangona kunjalo, kubalulekile ukuqaphela ukuba abaninzi abavelisi beebhetri bavumela ii-inverters ezininzi ukuba zifakwe ngokufanayo, ngaloo ndlela zandisa umthamo opheleleyo wokugcinwa kwenkqubo yokugcina amandla.
Umgangatho 6: Ugcino kunye nosetyenziso lwe-Off-grid
Ngamaxesha okungazinzi kwamandla kunye nesisongelo sokumka kombane ehlabathini lonke, abantu abaninzi ngakumbi bafuna izixhobo zabo zikwazi ukumelana neziganeko ezingalindelekanga. Ke ngoko, ukuba nezicelo ezinje ngemveliso yamandla kaxakeka okanye i-backup, okanye ukukwazi ukusebenza ngaphandle kwegridi kwimeko yokucima kombane, yinto ebaluleke kakhulu.
Kwi-2024 yethu uthelekiso lweebhetri ze-lithium eziphezulu ze-voltage, zonke zineziphumo ezingxamisekileyo okanye ze-backup, kwaye Iyakwazi ukuxhasa ukusebenza kwegridi edibeneyo okanye ngaphandle kwegridi.
Umgangatho 7: Inqanaba loKhuselo
Abavelisi beenkqubo zokugcina amandla babonisa iimveliso zabo kuluhlu lweemvavanyo ukubonisa ukukhuselwa kwabo kuluhlu lwezinto ezisingqongileyo.
Ngokomzekelo, kwi-2023 yethu yokuthelekisa iibhetri ze-lithium eziphezulu ze-voltage, ezintathu (i-BYD, i-Sungrow, kunye ne-LG) zinezinga lokukhusela i-IP55, kwaye i-BSLBATT inezinga lokukhusela i-IP54; oku kuthetha ukuba, ngelixa kungenamanzi, uthuli alukwazi ukuphazamisa ukusebenza ngokufanelekileyo kwesixhobo kwaye lukhusela emanzini kuxinzelelo oluthile; oku kuvumela ukuba zifakwe ngaphakathi kwindlu okanye kwigaraji okanye ishedi.
Ibhetri eveleleyo kulo mgaqo yiHuawei Luna 2000, enomlinganiselo wokukhusela we-IP66, okwenza kube nzima uthuli kunye neejethi zamanzi ezinamandla.
Umgangatho 8: Iwaranti
Iwaranti yindlela yokuba umenzi abonise ukuba uyayithemba imveliso yakhe, kwaye inokusinika umkhondo malunga nomgangatho wayo. Kule nkalo, ngaphezu kweminyaka yewaranti, kubalulekile ukuba uqaphele indlela ibhetri eya kusebenza ngayo emva kwaloo minyaka.
Kuthelekiso lwethu lwe-2024 yeebhetri ze-lithium eziphezulu, zonke iimodeli zibonelela ngewaranti yeminyaka eli-10. Kodwa, i-LG ESS Flex, ivelele phakathi kwabanye, inika ukusebenza kwe-70% emva kweminyaka eyi-10; I-10% ngaphezu kwabo bakhuphisana nabo.
I-Fox ESS kunye ne-Sungrow, kwelinye icala, abakakhuphi ixabiso elithile le-EOL kwiimveliso zabo.
