Umbhali: Isihleli Sesihleli Sendawo Shicilela: 2024-10-25 ORORGIGA: Isizango
Kubuchwepheshe besimanje sebhethri, sivame ukuhlangana nethemu 'Battery Balancing. ' Kepha kusho ukuthini? Impande imbangela ilele kwinqubo yokukhiqiza kanye nezinto zokwakha ezisetshenziswe kumabhethri, okuholela ekutheni umehluko phakathi kwamaseli ngamanye angena kwiphakethe lebhethri. Lo mehluko uthonywe yimvelo lapho amabhethri asebenza khona, njengokushisa kanye nomswakama. Lokhu kuhlukahluka kuvame ukubonakala njengomehluko ku-Battery Voltage. Ngokwengeziwe, amabhethri ngokwemvelo ahlangabezana nokuzenzela ngenxa yokuvela kwezinto ezisebenzayo ezivela ku-electrodes kanye nomehluko ongaba khona phakathi kwamapuleti. Amanani wokuzikhulula angahluka phakathi kwamabhethri ngenxa yokwehluka kwezinqubo zokukhiqiza.
Masibonise lokhu ngesibonelo: Ake sithi epakethe lebhethri, iseli elilodwa linesimo esiphakeme semali ekhokhwayo (SOC) kunabanye. Ngesikhathi senqubo yokushaja, leli seli lizofinyelela ngokugcwele kuqala, okwenza amanye amaseli awakakhokhiswa ngokuphelele ukuyeka ukushaja ngaphambi kwesikhathi. Ngakolunye uhlangothi, uma iseli elilodwa line-soc ephansi, lizofinyelela i-voltage yalo yokucisha kuqala ngesikhathi sokuphuma, ukuvimbela amanye amaseli ukuthi adedele amandla abo agcinwe.
Lokhu kukhombisa ukuthi umehluko phakathi kwamaseli ebhethri awunakwa. Ngokusekelwe kulokhu kuqonda, isidingo sokulinganisa ibhethri kuphakama. Ubuchwepheshe bebhethri bebhethri buhlose ukunciphisa noma ukuqeda umehluko phakathi kwamaseli ngamanye ngokungenelela kwezobuchwepheshe ukwenza kahle ukusebenza kwebhethri futhi kunwebe isikhathi sayo sokuphila. Hhayi nje kuphela ukulinganisa kwebhethri kuthuthukisa ukusebenza kahle kwephakethe lebhethri, kepha futhi kwandise kakhulu impilo yebhethri. Ngakho-ke, ukuqonda umongo kanye nokubaluleka kokulinganisa kwebhethri kubalulekile ukwenza kahle ukusetshenziswa kwamandla.
Incazelo: Ukulinganisa kwebhethri kubhekisele ekusebenziseni amasu athile nezindlela zokuqinisekisa ukuthi iseli ngalinye ephaketheni lebhethri ligcina ama-voltage, umthamo, kanye nezimo zokusebenza. Le nqubo ihlose ukulungiselela ukusebenza kwebhethri futhi yandise isikhathi sayo sokuphila ngokungenela kwezobuchwepheshe.
Ukubaluleka: Okokuqala, ukulinganisa kwebhethri kungathuthukisa kakhulu ukusebenza kwephakethe lebhethri lonke. Ngokulinganisa, ukucekelwa phansi kokusebenza okubangelwa ukuwohloka kwamaseli ngamanye kungagwenywa. Okwesibili, ukulinganisa kuyasiza ukunweba isikhathi sokuphila kwebhethri ngokunciphisa umehluko wamandla kagesi kanye namakhono phakathi kwamaseli nokwehlisa ukumelana kwangaphakathi, okwandisa ngempumelelo impilo yebhethri, eyandisa ngempumelelo impilo yebhethri. Okokugcina, ekubukeni kwebhethri, ukusebenzisa i-Battery Balancing kungavimbela ukwedlula ngokweqile noma ukukhipha amaseli ngakunye, kunciphisa ubungozi bokuphepha obufana nokubaleka okushisayo.
Idizayini yebhethri: Ukubhekana nokungahambisani nokusebenza phakathi kwamaseli ngamanye, abakhiqizi bebhethri amakhulu ngokuqhubekayo basungula futhi basebenzise izindawo ezifana ne-Battery Design, umhlangano, Ukulungiswa Kwezinqubo Zokukhiqiza, kanye nokulawula inqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nokulawulwa kwenqubo yokukhiqiza, kanye nesondlo. Le mizamo ifaka phakathi ukuthuthukisa ukwakhiwa kwamaselula, ukulungiselela ukwakhiwa kwamaphakethe, ukuthuthukisa inqubo inqubo, ukunquma ngokuqinile izinto ezingavuthiwe, ukuqinisa ukukhiqiza, kanye nokwenza ngcono ukukhiqiza.
I-BMS (uhlelo lokuqapha ibhethri) Umsebenzi wokulinganisa: Ngokushintsha ukusatshalaliswa kwamandla phakathi kwamaseli ngamanye, i-BMS inciphisa ukungahambisani futhi ikhulisa umthamo ongasebenziseka kanye nesikhathi sokuphila sephakethe lebhethri. Kunezindlela ezimbili eziphambili zokufinyelela ukulinganisa ku-BMS: Ukulinganisa nje nokulinganisa okusebenzayo.
Ukulinganisa nje, owaziwa nangokuthi ukulinganisa kokuhlanzeka kwamandla, kusebenza ngokukhulula amandla ngokweqile kusuka kumaseli anamandla kagesi aphezulu noma umthamo ngendlela yokushisa, ngaleyo ndlela kunciphisa amanye amaseli. Le nqubo incike kakhulu ekulweni okuhambisanayo okuxhunywe kumaseli ngamunye ukuze anikeze amandla ngokweqile.
Lapho iseli linecala eliphakeme kunabanye, amandla amaningi ahlakazwa ngokuphikiswa okufanayo, ukufeza ukulinganisela namanye amaseli. Ngenxa yokulula kwayo kanye nezindleko eziphansi, ukulinganisa nje kusetshenziswa kabanzi ezinhlelweni zebhethri ezahlukahlukene. Kodwa-ke, inokubuyisa ukulahleka kwamandla okuphambili, njengoba amandla ehlakazekile njengokushisa kunokuba asetshenziswe ngempumelelo. Onjiniyela bavame ukukhawulela ukulinganisa kwamanje kuya ezingeni eliphansi (ezungeze i-100mA). Ukwenza lula ukwakheka, inqubo yokulinganisa yabelana ngehhanisi elifanayo le-wiring nenqubo yokuqoqa, kanti nobabili zisebenza ngokuhlukile. Ngenkathi lo mklamo unciphisa ubunzima obuyinkimbinkimbi futhi kubiza, futhi kuphumela ekusebenzeni kahle kokulinganisa kanye nesikhathi eside ukufeza imiphumela ebonakalayo. Kunezinhlobo ezimbili eziphambili zokulinganisa nje: Ukumelana kwama-shunt okulungisiwe kanye nokushisekela okushintshiwe. Lowo owayekade uxhuma i-shunt ehleliwe ukuvikela ukweqile ngokweqile, kanti owokugcina ulawula ngokunembile ukushintshela ukuqeda amandla ngokweqile.
Ukulinganisa okusebenzayo, ngakolunye uhlangothi, kuyindlela esebenza kahle yokuphathwa kwamandla. Esikhundleni sokuqeda amandla ngokweqile, idlulisela amandla avela kumaseli anamandla aphezulu kulabo abanamandla aphansi abasebenzisa amaseli ahlelwe ngokukhethekile afaka izingxenye ezifana nezinto ezifana nezakhi. Lokhu akugcini nje ngokulinganisa amagesi phakathi kwamaseli kepha futhi kwandisa izinga lokusetshenziswa kwamandla.
Isibonelo, ngesikhathi sokushaja, lapho iseli lifinyelela umkhawulo walo ongenhla lomkhawulo, ama-BMs asebenze ngendlela esebenzayo yokulinganisa. Ikhomba amaseli anamandla aphansi futhi adlulisela amandla avela kwiseli eliphakeme lamandla ashukumisayo kulawa maseli aphansi aqukethe ngokucophelela umjikelezo weBalancer. Le nqubo iqondile futhi isebenza kahle, ithuthukisa kakhulu ukusebenza kwephakethe lebhethri.
Womabili la maqondana nokulinganisa okusebenzayo adlala izindima ezibucayi ekwandiseni umthamo osetshenziswayo wephakethe lebhethri, unwebe isikhathi sayo sokuphila, kanye nokwenza ngcono ukusebenza kahle kohlelo.
Uma uqhathanisa ubuchwepheshe obungenakulinganisa nowokulinganisa obusebenzayo, kuyacaca ukuthi bahluke kakhulu kwifilosofi yabo yokuqamba kanye nokubulawa kwabo. Ukulinganisa okusebenzayo kuvame ukufaka ama-algorithms ayinkimbinkimbi ukubala inani eliqondile lamandla okudlulisa, ngenkathi ukulinganisa nje kuncike kakhulu ekuzinikeleni isikhathi ngokunembe isikhathi sokusebenza kwemisebenzi yokushintsha.
Kuyo yonke inqubo yokulinganisa, uhlelo luqhubeka ngokushintsha izinguquko kumapharamitha weseli ngalinye ukuqinisekisa ukuthi imisebenzi yokulinganisa ayisebenzi kuphela kodwa futhi iphephile. Lapho umehluko phakathi kwamaseli ewa ngaphakathi kwebanga elamukelekayo elichaziwe, uhlelo luzophela ukusebenza kokulinganisa.
Ngokukhetha ngokucophelela indlela efanelekile yokulinganisa, elawula ngokuqinile ijubane lokulinganisa kanye neziqu, futhi ukuphatha ngokushisa ngokushisa ngesikhathi senqubo yokulinganisa, ukusebenza kanye nesikhathi sokuphila sephakethe lebhethri kungathuthukiswa kakhulu.
