Izinzuzo Zomkhiqizo
- ukuphathwa okushisayo nokuvikelwa kwe-overvoltage
Ukuphatha okushisayo kungenye inselelo enkulu kubaklami beshaja yebhethri.Yonke i-chip yeshaja yehla ugesi phakathi nenqubo yokushaja ngenxa yokukhishwa kokushisa.Ukuze ugweme ukulimala kwebhethri noma ukucisha kwesistimu, amashaja amaningi ahlanganisa indlela ethile yokulawula ukulawula ukunqwabelana kokushisa.Amadivayisi amasha asebenzisa amasu empendulo athuthuke kakhulu ukuze ahlole ngokuqhubekayo izinga lokushisa lokufa futhi alungise inkokhiso yamanje ngokushintshashintsha noma ngokubala ngesilinganiso esilinganiselwe noshintsho kuzinga lokushisa elizungezile.Lobu buhlakani obakhelwe ngaphakathi buvumela i-chip yeshaja yamanje ukuthi yehlise kancane kancane amandla amanje okushaja kuze kube yilapho kufinyelelwa khona ukulingana nezinga lokushisa elishisayo liyeka ukunyuka.Lobu buchwepheshe buvumela ishaja ukuthi iqhubeke nokushaja ibhethri ngobuningi obunokwenzeka bamanje ngaphandle kokubangela ukuthi uhlelo luvaleke, ngaleyo ndlela kunciphe isikhathi sokushajwa kwebhethri.Amadivayisi amaningi amasha namuhla nawo azongeza indlela yokuvikela i-overvoltage.
Ishaja i-BQ25616JRTWRihlinzeka ngezici ezihlukahlukene zokuphepha zokushajwa kwebhethri nokusebenza kwesistimu, okuhlanganisa ukuqapha kwe-thermistor ye-thermistor engalungile yebhethri, ukushaja isibali-sikhathi sokuphepha kanye nokugcwala ngokweqile nokuvikelwa kwamanje.Ukulawula okushisayo kunciphisa amandla amanje lapho izinga lokushisa lokuhlangana lingaphezu kuka-110°C.Okukhiphayo kwe-STAT kubika isimo sokushaja nanoma yiziphi izimo zephutha.
Izimo zohlelo lokusebenza
I-chip yeshaja yebhethri ingeyohlobo lwe-chip yokuphatha amandla, uhla lohlelo lokusebenza lubanzi kakhulu.Ukuthuthukiswa kwama-chips okuphatha amandla kubalulekile ekuthuthukiseni ukusebenza komshini wonke, ukukhethwa kwama-chips okuphatha amandla kuhlobene ngokuqondile nezidingo zesistimu, kuyilapho ukuthuthukiswa kwama-chips okuphatha amandla edijithali kusadingeka ukuwela umgoqo wezindleko.
I-BQ25616/616J ididiyelwe kakhulu lokuphathwa kwebhethri yemodi yokushintsha engu-3-A kanye nedivayisi yokulawula indlela yamandla esistimu yebhethri ye-Li-Ion eyodwa kanye ne-Li-polymer.Isixazululo sihlanganiswe kakhulu ne-FET (RBFET, Q1), i-FET eshintshayo ohlangothini oluphezulu (HSFET, Q2), i-FET ehlangothini oluphansi (LSFET, Q3), kanye ne-FET yebhethri (BATFET, Q4) phakathi kwesistimu ne ibhethri.Indlela yamandla e-impedance ephansi ilungiselela ukusebenza kahle kwemodi yokushintsha, inciphisa isikhathi sokushajwa kwebhethri futhi inwebe isikhathi sokusebenza kwebhethri phakathi nesigaba sokushajwa.
