I-algorithm yokushaja ibhethri ibona ukushaja okuncane, ukushaja okusheshayo nokushaja okuzinzile

Ngokwezidingo zamandla zohlelo lokugcina, ibhethri ingaqukatha izingcezu ezi-4 noma i-lithium, engashintshwa ngama-adaptha wamandla ajwayelekile: ama-adaptha aqondile, izimbobo ze-USB noma amashaja emoto. Ngaphandle kwenani lamabhethri, uhlobo lwempahla yebhethri noma i-adaptha yamandla, lawa maphakethe ebhethri anezici zokushaja ezifanayo. Ngakho-ke i-algorithm yokushaja iyafana. I-algorithm yokushaja efanelekile yamabhethri e-lithium namabhethri e-lithium polymer angahlukaniswa ngezigaba ezintathu: ukushaja okunensayo, ukushaja okusheshayo nokushaja okuzinzile.

* Ukushaja kwamanje okuphansi. Isetshenziselwa ukushaja ibhethri lokuphuma okujulile. Lapho i-voltage yebhethri yehla cishe ngo-2.8V, ishajwa ngomsinga ozinzile ongu-0.1C.

*ukushaja okusheshayo. Uma i-voltage yebhethri idlula umkhawulo wokushaja okuconsisayo, amandla okushaja ayakhuphuka ukuze kutholakale ukushajwa okusheshayo. Ukushaja kwamanje kufanele kube ngaphansi kuka-1.0C.

*I-voltage yokuphepha. Phakathi nenqubo yokushaja okusheshayo, lapho i-voltage yebhethri ifinyelela ku-4.2V, iqala ukungena esigabeni sokuzinzisa i-voltage. Kulesi simo, ukushaja kungamiswa ubuncane bamanje bokushaja noma isibali sikhathi noma inhlanganisela yakho kokubili. Ukushaja kungamiswa uma ubuncane bamanje bungaphansi kuka-0.07C. Isibali sikhathi sicushwa isibali-sikhathi esisethiwe.

Amashaja amabhethri aphezulu ngokuvamile anezici ezengeziwe zokuphepha. Isibonelo, uma izinga lokushisa lebhethri lidlula iwindi elinikeziwe, ngokuvamile elingu-0°C ukuya ku-45°C, ukushaja kuzomiswa.

Ngokuqedwa kwamanye amadivaysi asezingeni eliphansi kakhulu, izindlela zamanje zokushaja zamabhethri e-lithium-ion/lithium polymer emakethe zisekelwe ekuhlanganisweni kwezimpawu zokushaja noma izingxenye zangaphandle zokushaja, hhayi kuphela ekusebenzeni okungcono kokushaja, kodwa futhi nokushaja. ukuphepha.

*I-Li-ion/polymer ukushaja ibhethri isibonelo okokufaka okukabili 1.2a ishaja yebhethri ye-lithium LTC4097

I-LTC4097 ingasetshenziswa njenge-adaptha yokuxhumana noma umthombo wamandla we-USB ukushaja ibhethri ye-lithium ion/polymer eyodwa. Umfanekiso 1 uwumdwebo wohlelo lweshaja yebhethri ye-lithium ye-LTC4097 ye-dual-input 1.2a, esebenzisa i-algorithm yokuqina yamanje kanye ne-voltage ukuze ishaje. Lapho ishaja kusukela kumandla we-adaptha yezokuxhumana, amandla okushaja ahlelekayo afika ku-1.2A, kuyilapho amandla kagesi e-USB afika ku-1A, futhi ibona ngokugcwele ukuba khona kwe-voltage ngayinye yokokufaka. Idivayisi iphinde inikeze umkhawulo wamanje we-USB. Izicelo zifaka ama-pda, izidlali zeMP3, amakhamera edijithali, izinto eziphathwayo zezokwelapha nezokuhlola, nomakhalekhukhwini abanezikrini ezinkulu ezinemibala. Izici zokusebenza: Asikho isilawuli esincane sangaphandle sokumisa ukushaja, ukutholwa okusebenzayo nokukhetha amandla okokufaka; ukushaja okuhlelekayo kwamanje i-adaptha yokuxhumana yokokufaka ngokumelana 1.2; ehlelekayo USB ukushaja samanje ngokusebenzisa ukumelana 1; 100% noma 20% isilungiselelo samanje sokushaja kwe-USB, Ukufakwa kwamandla okufakwayo kunomphumela kanye nephinikhodi ye-NTC bias (VNTC) engu-120mA, iphinikhodi ye-NTC thermistor input (NTC) ishajwa ngezinga lokushisa elishiwo, ukunemba kwe-voltage yebhethri engu-±0.6%, I-LTC4097 ingasetshenziswa njenge-adaptha yokuxhumana noma ukunikezwa kwamandla kwe-USB kwebhethri ye-lithium Charge ion/polymer. Ukushaja kusebenzisa i-algorithm ye-voltage ephephile yamanje/ephephile. Uma ishaja ngomphakeli wamandla we-adaptha yokuxhumana, amandla okushaja ahlelekayo afika ku-1.2A, kanti amandla kagesi e-USB afika ku-1A. Futhi ukuthi ingabe kukhona ukutholwa okusebenzayo kwe-voltage yetheminali ngayinye yokokufaka. Idivayisi iphinde inikeze umkhawulo wamanje we-USB. Izicelo zifaka ama-pda, izidlali zeMP3, amakhamera edijithali, izinto eziphathwayo zezokwelapha nezokuhlola, nomakhalekhukhwini abanezikrini ezinkulu ezinemibala.
