Wigeze wibaza uburyo aBMSirashobora kumenya ikigezweho cya batiri ya lithium? Harimo multimeter yubatswe muriyo?
Ubwa mbere, hari ubwoko bubiri bwa sisitemu yo gucunga bateri (BMS): verisiyo yubwenge nibikoresho. Gusa BMS ifite ubwenge ifite ubushobozi bwo kohereza amakuru agezweho, mugihe verisiyo yibikoresho ntabwo.
Ubusanzwe BMS igizwe no kugenzura imiyoboro ihuriweho (IC), guhinduranya MOSFET, imiyoboro ikurikirana, hamwe no kugenzura ubushyuhe. Ikintu cyingenzi kigize verisiyo yubwenge ni igenzura IC, ikora nkubwonko bwa sisitemu yo kurinda. Irashinzwe gukurikirana-igihe nyacyo cyo kugenzura amashanyarazi. Muguhuza numuyoboro ukurikirana, igenzura IC irashobora kubona neza amakuru ajyanye na bateri. Iyo ikigezweho kirenze imipaka yumutekano wateganijwe, igenzura IC ryihutira guca urubanza kandi bigatera ibikorwa byo kurinda.
None, ubu bumenyekana gute?
Mubisanzwe, sensor ya sensor ikoreshwa mugukurikirana ibigezweho. Iyi sensor ikoresha isano iri hagati ya magnetique hamwe nubu. Iyo umuyaga unyuze, umurima wa magneti ubyara hafi ya sensor. Rukuruzi rusohora ibimenyetso bya voltage bihuye nimbaraga zumurima wa magneti. Igenzura IC imaze kwakira iki kimenyetso cya voltage, ibara ingano nyayo ikoresheje algorithms y'imbere.
Niba ikigezweho kirenze agaciro kateganijwe mbere yumutekano, nkibisanzwe cyangwa bigufi byumuzunguruko, igenzura IC izahita igenzura byihuse MOSFET kugirango ihagarike inzira igezweho, irinde bateri na sisitemu yose yumuzunguruko.
Byongeye kandi, BMS irashobora gukoresha résistoriste hamwe nibindi bice kugirango ifashe mugukurikirana ubu. Mugupima imbaraga za voltage hejuru yumurwanya, ingano yubu irashobora kubarwa.
Uru ruhererekane rwibintu bigoye kandi bisobanutse byubushakashatsi hamwe nuburyo bwo kugenzura byose bigamije gukurikirana imigendekere ya batiri mugihe irinze ibintu bikabije. Bafite uruhare runini mugukoresha neza bateri ya lithium, kongera igihe cya bateri, no kongera ubwizerwe bwa sisitemu yose ya batiri, cyane cyane muri porogaramu za LiFePO4 hamwe nizindi sisitemu za BMS.
