I-Multifunctional power bank design yemishini encane yochwepheshe yangaphandle

Ngokusekelwe ekuntulekeni kwamanje kwamandla kagesi weselula wemishini yobuchwepheshe yangaphandle, kwaklanywa ugesi omncane ophathwayo wemishini yangaphandle yochwepheshe. Lokhu kunikezwa kwamandla kamakhalekhukhwini kunemisebenzi eminingi futhi kunganikeza amandla kagesi ukusuka ku-3.3 V kuya ku-12 V. Phakathi nenqubo yokuklama, ukwakheka kwesakhiwo nemisebenzi eminingi yokuphakelwa kwamandla kamakhalekhukhwini kwathuthukiswa, futhi izindlela ezimbili zokuphakela ugesi zathuthukiswa ngendlela entsha. Okokufaka kwamandla kagesi weselula kungenziwa ngokusekelwe kumaphaneli elanga, futhi iamplifier ye-common-emitter isetshenziselwa ukulawula ukuqhutshwa nokunqanyulwa kwe-diode yokulungisa. I-voltage iyancipha ibe ngu-5 V DC; amandla amakhulu angu-220 V angabuye aguqulwe ngokuqondile abe yi-5 V DC ngokusebenzisa ibhuloho le-transformer ne-rectifier, futhi agcinwe ebhethri. Ngaphezu kwalokho, umsebenzi wokulawula ugesi wokuphakelwa kwamandla kagesi wacutshungulwa ngokujula, futhi isekethe ye-amplifier eyisisekelo kanye nesekethe yokuya phansi yomugqa wamatheminali amathathu we-AMS1117 kwasetshenziswa ukuze kuzuzwe ukulawulwa kwamandla kagesi okungaguquki, futhi umgomo we-PWM wasetshenziswa ukulawula amandla kagesi ophumayo. Ngaphansi kokulawula okusizayo kwe-microcontroller, yafinyelelwa ku-3.3 V okukhipha amandla kagesi alungiseka ngokukhululekile phakathi kuka-~12 V. Ekugcineni, isifunda sokuvikela ukuphepha kokunikezwa kwamandla weselula saklanywa, futhi ukuhlolwa kwesekethe kagesi okulungisekayo nokulungisa kabusha kwalingiswa. Imiphumela yokuhlola etholiwe yayihambisana nemigomo elindelekile ngenani lama-99.95%, okubonisa ukuthi ukunikezwa kwamandla kamakhalekhukhwini okuklanyiwe kuyenzeka futhi kunengqondo.

Inkampani njengamanje inamalungelo obunikazi amaningi kanye namalungelo okushicilela esoftware, isikwazi kahle ubuchwepheshe obuphambili obuphambili emkhakheni wezobuchwepheshe bebhethri ye-lithium yokugcina amandla, futhi inamalungelo empahla yobuhlakani azimele ngokuphelele. Ayikwazi ukwenza ngokwezifiso izixazululo nemikhiqizo ehlukahlukene yebhethri ye-lithium yokugcina amandla kanye nemikhiqizo yamakhasimende, kodwa futhi izimisele ukuthi i-Yu ibambisane nabalingani bomhlaba wonke ukuze kwakhiwe isiteji sokubambisana senani le-lithium yebhethri yokugcina amandla kagesi.
