Kubijyanye no guhitamo no gukoresha sisitemu yo gukonjesha bateri, nyamuneka reba ibyatanzwe mbere.

Igishushanyo mbonera cyumutekano

Imiterere yumubiri nubumashini bigena ko ibikoresho bidashobora kugabanya umuriro nogusohora voltage. Iyo umuriro nogusohora voltage birenze igipimo cyagenwe, bizatera kwangirika bidasubirwaho bateri ya lithium. Niyo mpamvu, birakenewe kongeramo umuzenguruko wo kurinda kugirango ukomeze voltage numuyoboro wa selile yimbere muburyo busanzwe mugihe bateri ya lithium ikora. Kuri BMS ya bateri, imirimo ikurikira irakenewe:

  • Kwishyuza kurinda voltage: kwishyuza birenze imwe mumpamvu nyamukuru zitera guhunga ubushyuhe. Nyuma yo kwishyurwa birenze urugero, ibikoresho bya cathode bizasenyuka kubera irekurwa rya lithium ikabije, kandi electrode mbi nayo izagira imvura igwa, ibyo bigatuma igabanuka ryumuriro ndetse nubwiyongere bwibisubizo byuruhande, bifite ibyago byo guhunga ubushyuhe. Niyo mpamvu, ni ngombwa cyane guca ikigezweho mugihe nyuma yo kwishyuza bigeze kumupaka wo hejuru wa voltage ya selile. Ibi birasaba BMS kugira imikorere yo kwishyuza hejuru ya voltage ikingira, kugirango voltage ya selile ihore ibitswe mumurimo. Byaba byiza ko voltage yo gukingira itari agaciro kangana kandi igahinduka cyane, kuko ishobora gutera bateri kunanirwa guca amashanyarazi mugihe yuzuye, bikavamo amafaranga arenze. Umuvuduko wo gukingira wa BMS mubusanzwe wagenewe kuba umwe cyangwa munsi gato ya voltage yo hejuru ya selile.
  • Kwishyuza hejuru yuburinzi: Kwishyuza bateri ifite amashanyarazi arenze ayo kwishyuza cyangwa kurenza urugero bishobora gutera ubushyuhe. Iyo ubushyuhe bwegeranije bihagije kugirango ushonge diafragma, birashobora gutera umuzenguruko mugufi. Kubwibyo kwishyuza mugihe cyo kurinda kurubu nabyo ni ngombwa. Tugomba kwitondera ko kurinda kurubu bidashobora kuba hejuru kurenza kwihanganira ingirabuzimafatizo mugushushanya.
  • Gusezererwa kurinda voltage: Umuvuduko munini cyane cyangwa muto cyane byangiza imikorere ya bateri. Gukomeza gusohora munsi ya voltage bizatera umuringa kugwa hamwe na electrode mbi isenyuka, mubisanzwe rero bateri izaba isohotse mumikorere yo gukingira voltage.
  • Gusohora hejuru yuburinzi bugezweho: Byinshi muri PCB yishyuza no gusohora binyuze mumurongo umwe, muriki gihe amafaranga yo gukingira no gusohora ibintu birahoraho. Ariko bateri zimwe, cyane cyane bateri kubikoresho byamashanyarazi, kwishyuza byihuse nubundi bwoko bwa bateri zigomba gukoresha imiyoboro minini isohoka cyangwa ikarishye, ikigezweho ntigihuye muriki gihe, nibyiza rero kwishyuza no gusohora muburyo bubiri bwo kugenzura.
  • Kurinda umuzunguruko mugufi: Inzira ya bateri nayo nimwe mumakosa akunze kugaragara. Kugongana, gukoresha nabi, gukanda, inshinge, kwinjiza amazi, nibindi, biroroshye gutera inzira ngufi. Umuzunguruko mugufi uzahita ubyara amashanyarazi manini, bikavamo kuzamuka gukabije kwubushyuhe bwa bateri. Muri icyo gihe, urukurikirane rw'amashanyarazi rusanzwe rubera mu kagari nyuma y'umuzunguruko mugufi wo hanze, biganisha ku ruhererekane rw'imyitwarire idasanzwe. Kurinda umuzunguruko mugufi nabyo ni ubwoko bwokwirinda kurubu. Ariko imiyoboro ngufi yumuzingi izaba itagira iherezo, kandi ubushyuhe nibibi nabyo ntibigira iherezo, kurinda rero bigomba kuba byoroshye kandi birashobora guhita bikururwa. Ingamba zisanzwe zo kurinda imiyoboro zirimo abahuza, fuse, mos, nibindi
  • Kurenza ubushyuhe: Bateri yunvikana nubushyuhe bwibidukikije. Ubushyuhe bukabije cyangwa buke cyane bizagira ingaruka kumikorere. Kubwibyo, ni ngombwa gukomeza bateri ikora mubushyuhe ntarengwa. BMS igomba kugira imikorere yo kurinda ubushyuhe kugirango ihagarike bateri mugihe ubushyuhe buri hejuru cyangwa hasi cyane. Irashobora no kugabanywa muburyo bwo kurinda ubushyuhe no gusohora ubushyuhe, nibindi.
  • Kuringaniza imikorere: Kuri ikaye hamwe nizindi bateri nyinshi zikurikirana, hariho ukudahuza hagati ya selile bitewe nuburyo butandukanye mubikorwa byo gukora. Kurugero, selile zimwe zirwanya imbere nini kuruta izindi. Uku kudahuza bizagenda byiyongera buhoro buhoro bitewe n’ibidukikije byo hanze. Kubwibyo, birakenewe kugira imikorere yimicungire yimikorere kugirango ishyire mubikorwa uburinganire bwakagari. Muri rusange hari ubwoko bubiri buringaniye:

1.Kuringaniza neza: Koresha ibyuma, nka voltage igereranya, hanyuma ukoreshe ubushyuhe bwo kurwanya ubushyuhe kugirango urekure imbaraga zirenze za bateri ifite imbaraga nyinshi. Ariko gukoresha ingufu nini, umuvuduko wo kuringaniza uratinda, kandi imikorere ni mike.

2.Kuringaniza bifatika: koresha ubushobozi bwo kubika imbaraga za selile zifite ingufu nyinshi hanyuma ukayirekura muri selile hamwe na voltage yo hasi. Ariko, mugihe itandukaniro ryumuvuduko hagati ya selile yegeranye ari rito, igihe cyo kunganya ni kirekire, kandi kuringaniza voltage irashobora gushyirwaho byoroshye.
