Ialgorithm yokutshaja ibhetri ibona ukutshaja okuncinci, ukutshaja ngokukhawuleza kunye nokutshaja okuzinzileyo

Ngokweemfuno zamandla zesicelo sokugqibela, ipakethe yebhetri inokufikelela kwii-4 iziqwenga okanye i-lithium, enokuthi iguqulwe yi-adapters yamandla aqhelekileyo: i-adapters ngqo, i-USB port okanye iishaja zemoto. Kungakhathaliseki ukuba inani leebhetri, uhlobo lwezixhobo zebhetri okanye i-adapter yamandla, ezi zixhobo zebhetri zineempawu ezifanayo zokutshaja. Ke i-algorithm yokutshaja iyafana. I-algorithm efanelekileyo yokutshaja iibhetri ze-lithium kunye neebhetri ze-lithium ze-polymer zinokwahlulwa zibe ngamanqanaba amathathu: ukutshaja okucothayo, ukutshaja ngokukhawuleza kunye nokutshaja okuzinzile.

* Ukutshaja okuphantsi ngoku. Isetyenziselwa ukutshaja ibhetri ephuma nzulu. Xa i-voltage yebhetri yehla malunga ne-2.8V, ihlawuliswa ngokuzinzileyo kwe-0.1C.

*ukutshaja ngokukhawuleza. Xa amandla ombane ebhetri engaphaya komda wokutshaja, umsinga wokutshaja uyenyuka ukuze kufikelelwe ukutshaja ngokukhawuleza. Umbane wokutshaja ngokukhawuleza kufuneka ube ngaphantsi kwe-1.0C.

* Umbane wokhuseleko. Ngethuba lenkqubo yokutshaja ngokukhawuleza, xa i-voltage yebhethri ifikelela kwi-4.2V, iqala ukungena kwisigaba sokuzinzisa i-voltage. Kule meko, ukutshaja kunokumiswa ngokutshaja okuncinci okwangoku okanye isibali-xesha okanye indibaniselwano yazo zombini. Ukutshaja kunokumiswa xa ubuncinci bangoku bungaphantsi kwe-0.07C. Isibali-xesha siqaliswa sisibali-xesha esisetwe kwangaphambili.

Iitshaja zebhetri ezikumgangatho ophezulu zihlala zineempawu ezongezelelweyo zokhuseleko. Umzekelo, ukuba ubushushu bebhetri budlula ifestile enikiweyo, ngokuqhelekileyo ngu-0°C ukuya kuma-45°C, ukutshaja kuya kunqunyanyiswa.

Ngokupheliswa kwezixhobo ezikumgangatho ophantsi kakhulu, iindlela zangoku zokutshaja iibhetri ze-lithium-ion/lithium polymer kwimarike zisekwe ekudityanisweni kweempawu zokutshaja okanye iinxalenye zangaphandle zokutshaja, kungekuphela nje ukwenza ngcono ukutshaja, kodwa nakwindlela yokutshaja. ukhuseleko.

*I-Li-ion/i-polymer ibhetri yokutshaja umzekelo-igalelo eliphindwe kabini 1.2a itshaja yebhetri ye-lithium LTC4097

I-LTC4097 ingasetyenziswa njenge-adapter yonxibelelwano okanye umthombo wamandla we-USB ukutshaja i-lithium ion ion/polymer ibhetri. Umzobo we-1 ngumzobo we-skim ye-LTC4097 i-double-input 1.2a ishaja yebhethri ye-lithium, esebenzisa i-algorithm yangoku kunye ne-voltage stabilization algorithm yokutshaja. Xa utshaja umbane we-adapter yonxibelelwano, ukutshaja okucwangcisiweyo kwangoku ukuya kuthi ga kwi-1.2A, ngelixa unikezelo lwamandla e-USB lufikelela kwi-1A, kwaye lubona ngenkuthalo ubukho bombane ngamnye. Isixhobo sikwabonelela ngomda wangoku we-USB. Izicelo ziquka iipdas, iiMP3 player, iikhamera zedijithali, izixhobo eziphathwayo zonyango kunye novavanyo, kunye neeselfowuni ezinezikrini ezinkulu zemibala. Iimpawu zokusebenza: Akukho microcontroller yangaphandle yokuyeka ukutshaja, ukufumanisa okusebenzayo kunye nokukhetha amandla okufakwayo; ukutshaja okucwangcisiweyo ngoku iadaptha yonxibelelwano lwegalelo ngokumelana 1.2; Ukutshaja okucwangcisiweyo kwe-USB yangoku ngokuxhathisa 1; I-100% okanye i-20% ye-USB yokutshaja isethingi yangoku, Ukunikezelwa kwamandla okufakwayo kunemveliso kunye ne-NTC bias (VNTC) iphini ye-120mA yokuqhuba, i-NTC ye-thermistor input (NTC) i-pin ihlawuliswa kwiqondo lokushisa elichaziweyo, ukuchaneka kwe-voltage ye-battery yi-± 0.6%, I-LTC4097 ingasetyenziswa njenge-adapter yonxibelelwano okanye unikezelo lwamandla e-USB kwi-lithium enye I-ion / ibhetri yepolymer. Ukutshaja kwamkela ialgorithm yombane ekhuselekileyo yangoku/ekhuselekileyo. Xa utshaja ngonikezelo lwamandla lwe-adaptha yonxibelelwano, ukutshaja okucwangcisiweyo kwangoku ukuya kuthi ga kwi-1.2A, kwaye umbane we-USB ufikelele kwi-1A. Kwaye nokuba kukho ukubonwa okusebenzayo kombane we-terminal nganye yokufaka. Isixhobo sikwabonelela ngomda wangoku we-USB. Izicelo ziquka iipdas, iiMP3 player, iikhamera zedijithali, izixhobo eziphathwayo zonyango kunye novavanyo, kunye neeselfowuni ezinezikrini ezinkulu zemibala.
