Li-betri tsa LiFePO4(Lithium Iron Phosphate Batteries) li tumme ka polokeho ea tsona, bophelo bo bolelele, le botsoalle ba tikoloho, e leng se etsang hore e be tse loketseng lisebelisoa tsa letsatsi, li-EV, le tse ling. Ho khetha tlhophiso e nepahetseng ea letoto ke senotlolo sa ho ntlafatsa motlakase le ts'ebetso. Tataiso ena e hlalosa LiFePO4 lithium battery series mme e u thusa ho khetha setup se setle ka ho fetisisa bakeng sa litlhoko tsa hau.
1. Betri ea LiFePO4 ke Eng?
Betri ea LiFePO4, kapa betri ea Lithium Iron Phosphate, ke mofuta oa betri ea lithium-ion e tsejoang ka polokeho ea eona e ikhethang, nako e telele ea bophelo, le botsoalle ba tikoloho. Ho fapana le setso sa lead-acid kapa lik'hemik'hale tse ling tsa lithium-ion,LiFePO4 libeteri tsa lithiumli hanyetsana le mocheso o feteletseng, li fana ka tlhahiso ea matla e tsitsitseng, 'me li hloka tlhokomelo e fokolang.
Li sebelisoa haholo ho:
- ⭐ Lisebelisoa tsa betri tsa polokelo ea letsatsi;
- ⭐ Likoloi tsa motlakase (EVs);
- ⭐ Kopo ea metsing;
- ⭐ Liteishene tsa motlakase tse nkehang.
Ka moralo oa bona o bobebe le matla a phahameng a matla, libeteri tsa letsatsi tsa LiFePO4 li fetoha khetho ea mantlha bakeng sa polokelo ea matla e tsitsitseng le e sebetsang hantle.
2. Ho utloisisa LiFePO4 Battery Series Configurations
Battery ea LFPLitlhophiso tsa letoto li bohlokoa bakeng sa ho eketsa voltage ea betri lits'ebetsong tsa matla.
Ka setupong sa letoto, lisele tse ngata tsa betri tsa LiFePO4 li hokahane, ka terminal e ntle ea e 'ngoe e hokahaneng le terminal e mpe ea e latelang. Tokisetso ena e kopanya motlakase oa lisele tsohle tse hokahaneng ha o ntse o boloka matla (Ah) a sa fetohe.
- Ka mohlala, ho kopanya lisele tse 'nè tsa 3.2V LiFePO4 letotong ho hlahisa betri ea 12.8V.
Litlhophiso tsa Series li bohlokoa bakeng sa lits'ebetso tse hlokang motlakase o phahameng, joalo ka lisebelisoa tsa matla a letsatsi, likoloi tsa motlakase, le tharollo ea matla a backup. Li etsa hore litsamaiso li sebetse hantle ka ho fokotsa phallo ea hona joale, ho fokotsa tahlehelo ea mocheso, le ho etsa bonnete ba ho lumellana le lisebelisoa tse phahameng tsa motlakase.
Leha ho le joalo, li-setups tsa letoto li hloka taolo e nepahetseng, joalo ka ho sebelisa sistimi ea taolo ea betri (BMS), ho boloka botsitso le ho thibela ho tjhaja kapa ho tjhaja. Ka ho utloisisa hore na litlhophiso tsa letoto li sebetsa joang, o ka ntlafatsa ts'ebetso le nako ea bophelo ea betri ea hau ea LiFePO4.
