IiNzuzo zeMveliso
- ulawulo lwe-thermal kunye nokukhuselwa kwe-overvoltage
Ulawulo lobushushu ngomnye umngeni omkhulu kubayili betshaja yebhetri.Yonke itshiphu yetshaja ifumana ukuhla kwamandla ombane ngexesha lenkqubo yokutshaja ngenxa yokutshatyalaliswa kobushushu.Ukunqanda ukonakala kwebhetri okanye ukuvalwa kwenkqubo, uninzi lweetshaja zisebenzisa indlela yokulawula ubushushu.Izixhobo ezitsha zisebenzisa iindlela ezintsonkothileyo zokuphendula ukujonga ngokuqhubekayo ubushushu bokufa kunye nokulungelelanisa intlawulo yangoku ngokuguquguqukayo okanye ngokubala ngomlinganiselo ohambelana notshintsho kwiqondo lobushushu elingqongileyo.Ubukrelekrele bakhelwe ngaphakathi buvumela itshiphu yetshaja yangoku ukuba icuthe kancinci umsinga wokutshaja de kufike ukulingana kwe-thermal kunye nobushushu bokufa buyeke ukunyuka.Obu buchwepheshe buvumela itshaja ukuba iqhubeke ukutshaja ibhetri ngowona mlinganiselo uphezulu ukhoyo ngoku ngaphandle kokubangela ukuba isixokelelwano sivale, nto leyo inciphisa ixesha lokutshaja kwebhetri.Uninzi lwezixhobo ezitsha namhlanje ziya kongeza indlela yokukhusela i-overvoltage.
Itshaja ye-BQ25616JRTWRIbonelela ngeempawu zokhuseleko ezahlukeneyo zokutshaja ibhetri kunye nokusebenza kwenkqubo, kubandakanywa ujongo lwe-thermistor engafanelekanga yebhetri, ukutshaja isibali-xesha sokhuseleko kunye nokugqithisa kunye nokhuseleko lwangoku.Ulawulo lwe-Thermal lunciphisa intlawulo yangoku xa ubushushu besiphambuka budlula i-110°C.Isiphumo se-STAT sibika imeko yokutshaja kunye naziphi na iimeko eziphosakeleyo.
Iimeko zeSicelo
Itshiphu yetshaja yebhetri yeyohlobo lwetshiphu yolawulo lwamandla, uluhlu lwesicelo lubanzi kakhulu.Ukuphuhliswa kweetshiphusi zolawulo lwamandla kubalulekile ekuphuculeni ukusebenza komatshini wonke, ukukhethwa kweetshiphusi zolawulo lwamandla kuhambelana ngokuthe ngqo neemfuno zenkqubo, ngelixa ukuphuhliswa kweetshiphusi zolawulo lwamandla edijithali kusafuneka ukuwela umqobo weendleko.
I-BQ25616/616J idityaniswe kakhulu i-3-A yokutshintsha-imowudi yolawulo lwentlawulo yebhetri kunye nesixhobo sokulawula indlela yamandla esixhobo kwiseli enye i-Li-Ion kunye ne-Li-polymer ibhetri.Isisombululo sidityaniswe kakhulu ne-FET (RBFET, Q1), i-high-side switching FET (HSFET, Q2), iFET (LSFET, Q3), kunye ne-FET yebhetri (BATFET, Q4) phakathi kwenkqubo kunye ibhetri.Indlela yombane ephantsi yombane iphucula ukusebenza kwemowudi yokutshintsha, inciphisa ixesha lokutshaja ibhetri kwaye yandise ixesha lokuqhuba kwebhetri ngexesha lesigaba sokukhupha.
I-BQ25616/616J idityaniswe kakhulu i-3-A yokutshintsha-imowudi yolawulo lwentlawulo yebhetri kunye nenkqubo yolawulo lweNdlela yoMbane yesixhobo kwi-Li-ion kunye ne-Li-polymer iibhetri.Ifaka ukutshaja okukhawulezayo kunye nenkxaso yombane ophezulu wokufakwa kuluhlu olubanzi lwezicelo ezibandakanya izithethi, ishishini, kunye nezixhobo eziphathwayo zonyango.Indlela yayo yamandla ephantsi yokuthintela iphucula ukusebenza kwemowudi yokutshintsha, inciphisa ixesha lokutshaja ibhetri, kwaye yandisa ixesha lokubaleka kwebhetri ngexesha lesigaba sokukhupha.Igalelo layo lombane kunye nommiselo wangoku uhambisa amandla aphezulu okutshaja kwibhetri.
Isisombululo sidityaniswe kakhulu ne-FET (RBFET, Q1), i-high-side switching FET (HSFET, Q2), iFET (LSFET, Q3), kunye ne-FET yebhetri (BATFET, Q4) phakathi kwenkqubo kunye ibhetri.Ikwadibanisa i-bootstrap diode ye-high-side gate drive yoyilo lwenkqubo olulula.Ukusetwa kwehardware kunye nengxelo yobume kunika uqwalaselo olulula ukuseta isisombululo sokutshaja.
