Uhlobo lwebhethri olungcono kakhulu lokugcina amandla elanga
Ukugcina amandla kuyinhliziyo yesistimu yamandla elanga, ikakhulukazi uma ufuna ukugcina amandla ebusuku, ngesikhathi sezulu esinamafu, noma ngesikhathi sokuphela kukagesi. Amaphaneli elanga akhiqiza ugesi emini, kodwa izidingo zamandla zasekhaya noma zebhizinisi zivame ukusebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto. Yilapho amabhethri engena khona: ukugcina ugesi owengeziwe ukuze uphinde usetshenziswe uma kudingeka. Kodwa-ke, ukukhetha ibhethri akulula njengokuthola umthamo omkhulu kunayo yonke. Udinga ukucabangela isikhathi sokuphila, ukusebenza kahle, ukuphepha, izindleko, kanye nokuhambisana ne-inverter yakho kanye namaphethini okusebenzisa amandla. Lesi sihloko sixoxa ngezinhlobo ezinhle kakhulu zamabhethri okugcina amandla elanga, kanye nezinzuzo zawo, ukungalungi kwawo, kanye nokusetshenziswa okunconywayo.
1) Amabhethri e-Lithium Iron Phosphate (LiFePO4/LFP) – ukukhetha okulinganiselayo kakhulu
Eminyakeni yamuva nje, i-LiFePO4 (evame ukufushaniswa ngokuthi i-LFP) ibe ngenye yezinketho ezithandwa kakhulu zezinhlelo zamandla elanga, kokubili zokuhlala kanye nezentengiso ezilula. Uma kuqhathaniswa namabhethri esizukulwane sangaphambilini “e-lithium-ion” avame ukusetshenziswa kumadivayisi eselula, i-LFP inikeza ukuphepha okuthuthukisiwe kokushisa, ukuzinza okuphezulu kwamakhemikhali, kanye nokuphila komjikelezo omude.
Izinzuzo ze-LFP:
– Impilo yomjikelezo omude: ingafinyelela izinkulungwane zemijikelezo yokushaja nokukhipha ishaja (kuye ngokuthi ukujula kokukhipha/i-DoD kanye nekhwalithi ye-BMS kujule kangakanani).
