Ho na le haholo-holo mekhoa e latelang ea holithium betriho eketsa motlakase:
Mokhoa oa ho matlafatsa:
Ho sebelisa boost chip:ena ke mokhoa o atileng haholo oa ho matlafatsa. Boost chip e ka phahamisa voltage e tlase ea betri ea lithium ho ea ho matla a holimo a hlokahalang. Ka mohlala, haeba u batla ho phahamisa le3.7V lithium betrimotlakase ho 5V ho fana ka matla ho sesebelisoa, o ka sebelisa chip e loketseng ea boost, joalo ka KF2185 joalo-joalo. Li-chips tsena li na le ts'ebetso e phahameng ea phetoho, li ka tsitsisoa molemong oa liphetoho tsa motlakase oa ho kenya tlhahiso ea sete ea boost voltage, potoloho ea peripheral e bonolo, e bonolo ho e qapa le ho e sebelisa.
Ho amohela li-circuits le li-circuits tse amanang le tsona:Boost voltage e bonoa ka molao-motheo oa motlakase oa motlakase oa transformer. Phallo ea DC ea betri ea lithium e qala ho fetoloa ho AC, ebe motlakase o eketsoa ke transformer, 'me qetellong AC e lokisoa ho khutlela ho DC. Mokhoa ona o ka sebelisoa ka linako tse ling ka litlhoko tse phahameng tsa motlakase le matla, empa moralo oa potoloho o batla o rarahane, o moholo ebile o theko e boima.
Ho sebelisa pompo ea motlakase:pompo ea charger ke potoloho e sebelisang li-capacitor joalo ka likarolo tsa polokelo ea matla ho lemoha phetoho ea motlakase. E ka atisa le ho phahamisa matla a betri ea lithium, mohlala, ho phahamisa matla a 3.7V ho ea ho matla a makhetlo a mabeli kapa a mangata a phahameng. Potoloho ea pompo ea ho tjhaja e na le melemo ea ts'ebetso e phahameng, boholo bo nyane, litšenyehelo tse tlase, tse loketseng tse ling tsa sebaka se phahameng le litlhoko tse sebetsang tsa lisebelisoa tse nyane tsa elektroniki.
Mekhoa ea ho bucking:
Sebelisa buck chip:Buck chip ke potoloho e khethehileng e kopantsoeng e fetolang voltage e phahameng ho ea tlase. Bakeng salibeteri tsa lithium, motlakase o pota-potileng 3.7V hangata o fokotsehile ho ea ho matla a tlaase a kang 3.3V, 1.8V ho finyella litlhoko tsa phepelo ea matla a likarolo tse fapaneng tsa elektronike. Li-chips tse tloaelehileng tsa buck li kenyelletsa AMS1117, XC6206 joalo-joalo. Ha u khetha chip ea buck, u lokela ho khetha ho ea ka tlhahiso ea hona joale, phapang ea voltage, botsitso le litekanyetso tse ling.
Series resistance voltage divider:mokhoa ona ke ho hokela resistor letoto la lihlooho tse ka potoloho, e le hore karolo ea gagamalo marotholi ka resistor, kahoo hlokomela phokotso ea lithium betri gagamalo. Leha ho le joalo, phello ea ho fokotsa matla a mokhoa ona ha e tsitsitse haholo 'me e tla angoa ke liphetoho tsa moroalo oa hona joale,' me mohanyetsi o tla sebelisa matla a itseng, e leng se etsang hore ho be le litšila tsa matla. Ka hona, mokhoa ona hangata o loketse feela liketsahalong tse sa hlokeng ho nepahala ha motlakase o phahameng le moroalo o monyane oa hona joale.
Linear voltage regulator:Linear voltage regulator ke sesebelisoa se hlokomelang tlhahiso e tsitsitseng ea motlakase ka ho fetola boemo ba conduction ba transistor. E ka tsitsisa voltage ea betri ea lithium ho ea ho boleng ba voltage e hlokahalang, ka matla a tsitsitseng a tsoang, lerata le tlase le melemo e meng. Leha ho le joalo, ts'ebetso ea li-linear regulator e tlase, 'me ha phapang pakeng tsa li-voltages tsa ho kenya le ho tsoa e le khōlō, ho tla ba le tahlehelo e eketsehileng ea matla, e leng se etsang hore ho be le mocheso o moholo oa mocheso.
