Isingeniso:
Emkhakheni wokulungiswa kwebhethri, ukuhambisana kwephakethe lebhethri kuyisici esiyinhloko, esithinta ngokuqondile impilo yesevisi yamabhethri e-lithium. Kodwa lokhu kuvumelana kubhekisela kuphi ngempela, futhi kungahlulelwa kanjani ngokunembile? Isibonelo, uma kunomehluko kumthamo phakathi kwamabhethri, ungakanani lo mehluko okufanele ulawulwe ngendlela efanele? Lokhu kubalulekile ngoba kuthinta ukuthi ibhethri lakho le-lithium lingahlala isikhathi esingakanani.
Ukuvumelana kwamabhethri kuwumqondo obaluleke kakhulu emkhakheni wamabhethri. Kalula nje, kungcono ukuvumelana kwephakethe lebhethri, kulapho lingashaja khona noma likhulule, futhi izinga lokusebenzisa lonke iphakethe lebhethri nalo lizothuthukiswa kakhulu. Ngokukhethekile, ukungaguquguquki kwebhethri kuhlanganisa izici eziyisishiyagalombili eziyinhloko, okuyi-voltage, umthamo, ukumelana kwangaphakathi, isilinganiso samanje esiqhubekayo, i-plateau yokukhipha, impilo yomjikelezo, ukushaja kwe-SOC, nezinga lokuzikhiphela ngokwakho. Uma kubhekwa inkimbinkimbi yayo yonke incazelo, sizogxila ekuhlaziyeni izici ezintathu ezibalulekile okulula ukuzilawula nokwahlulela.
Ukuvumelana kwamabhethri
Ukuvumelana kwamabhethri kuwumqondo obaluleke kakhulu emkhakheni wamabhethri. Kalula nje, kungcono ukuvumelana kwephakethe lebhethri, kulapho lingashaja khona noma likhulule, futhi izinga lokusebenzisa lonke iphakethe lebhethri nalo lizothuthukiswa kakhulu. Ngokukhethekile, ukungaguquguquki kwebhethri kuhlanganisa izici eziyisishiyagalombili eziyinhloko, okuyi-voltage, umthamo, ukumelana kwangaphakathi, isilinganiso samanje esiqhubekayo, i-plateau yokukhipha, impilo yomjikelezo, ukushaja kwe-SOC, nezinga lokuzikhiphela ngokwakho. Uma kubhekwa inkimbinkimbi yayo yonke incazelo, sizogxila ekuhlaziyeni izici ezintathu ezibalulekile okulula ukuzilawula nokwahlulela.
Ukuvumelana kwe-voltage
Okokuqala, ukuhambisana kwe-voltage. Ikakhulukazi ngaphambi kokuhlanganisa amabhethri e-lithium, kuyadingeka ukuqinisekisa ukuthi i-voltage phakathi kweseli ngayinye ihambisana ngokuphelele. Emkhakheni wejubane eliphansi noma wokugcina amandla, ngokuvamile kubhekwa njengokuhlangabezana nezinga lokulawula ngokuqinile inani lephutha likagesi ngaphakathi kwamamilivolthi angu-5. Kungakho futhi ukukalwa ngokucophelela kwamandla kagesi kuyisinyathelo esiyinhloko nesibalulekile ngaphambi kokuhlanganisa amabhethri e-lithium. Isibonelo, kuphakethe lebhethri elakhiwe amaseli ebhethri amaningi, uma ukuchezuka kwamandla kagesi weseli eyodwa yebhethri kusuka kwamanye kudlula amamilivolthi angu-5, iseli yebhethri ingase ihlangabezane nokushajwa ngokweqile noma ukushajwa okungaphansi phakathi nenqubo yokushaja. Ngokuhamba kwesikhathi, lokhu akuthinti kuphela ukusebenza okuphelele kwephakethe lebhethri, kodwa futhi kunciphisa kakhulu impilo yayo yesevisi.
Ukuvumelana kwamandla
Okwesibili, usayizi womthamo phakathi kweseli ngalinye lebhethri kufanele ugcinwe ulingana ngangokunokwenzeka. Esimeni esifanele, umthamo weseli yebhethri ngayinye akumele uhluke, kodwa ekukhiqizeni nasekusetshenzisweni kwangempela, kucishe kube nzima ukuzuza ukuvumelana okuphelele. Ngakho-ke, inani lephutha lomthamo ngokuvamile lilawulwa cishe ku-2% ngangokunokwenzeka. Yiqiniso, eqenjini lamabhethri, kuyamukeleka ukuthi amangqamuzana ngamanye abe nomthamo ophakeme kancane, kodwa ekusetshenzisweni kwangempela, kufanele aphathwe ngokuvumelana nezindinganiso zamaseli amandla aphansi. Isibonelo, kusistimu yebhethri engu-48 volt ehlanganisa amaseli ebhethri angu-16 axhunyiwe, lapho umthamo wamaseli angu-15 ufana ngokuyisisekelo, futhi umthamo weseli ye-16 uphakeme kancane, umthamo wangempela otholakalayo wephakethe lebhethri lonke kufanele usekelwe kumthamo ophansi walawa maseli angu-15. Ngenxa yokuthi ibhethri liyafana ochungechungeni lwephakethe lebhethri elixhunyiwe, uma lishajwe futhi lilahlwa ngokuya ngezindinganiso zamaseli anamandla amakhulu, amaseli omthamo ophansi angase alimale ngenxa yokushajwa nokushajwa ngokweqile, ngaleyo ndlela kuthinte ukusebenza nokuphila kwalo lonke iphakethe lebhethri. .
Ukuvumelana kokumelana kwangaphakathi
Into yokugcina ukukhuluma ngayo ukumelana kwangaphakathi. Umehluko wokumelana kwangaphakathi phakathi kweseli ngalinye kuphakethe lebhethri kufanele uncishiswe, futhi ngokuvamile kufanelekile ukuwulawula ngaphakathi kuka-15%. Umehluko omncane wokumelana kwangaphakathi unganciphisa ngempumelelo ukungalingani kwamabhethri ngesikhathi sokushaja nokukhipha. Iphakethe lebhethri elinokuqina okuhle kwangaphakathi linganciphisa kakhulu ukulahleka kwamandla kanye nokukhiqizwa kokushisa ngesikhathi sokushaja nokukhipha. Ukuthatha iphakethe lebhethri lezimoto zikagesi njengesibonelo, uma ukuhambisana kokumelana kwangaphakathi kwamaseli ebhethri kungalungile, ngesikhathi sokushaja okusheshayo, amaseli anokumelana okuphezulu kwangaphakathi azokhiqiza ukushisa okwengeziwe, okungagcini nje ukunciphisa ukusebenza kahle kokushaja, kodwa futhi kungase kubangele izingozi zokuphepha ezifana nokushisa nomlilo. Uma ukuhambisana kokumelana kwangaphakathi kuqinisekisiwe, ukushaja nokukhipha ukusebenza kahle kwephakethe lebhethri kungathuthukiswa, nokuphepha kungathuthukiswa kakhulu.
I-Heltec Battery Equalizer
Kafushane, ohlelweni lokukhanda ibhethri, ukuhlanganisa, kanye nokusetshenziswa kwamaphakethe ebhethri, kubalulekile ukunaka ngokugcwele futhi ulawule ngokuqinile ukuvumelana kwebhethri, ikakhulukazi ezicini ezintathu ezibalulekile zamandla kagesi, umthamo, nokumelana kwangaphakathi, ukuze kunwetshwe impilo yebhethri futhi kuthuthukiswe ukusebenza kwephakethe lebhethri.
Ohambweni lokuqinisekisa ukuvumelana kwebhethri, yethuisilinganisi sebhethriingathathwa njengomsizi onokwethenjelwa, ofanele izimoto ezintsha zamandla namabhethri emoto kagesi, futhi angakwazi ukuqapha ngokunembile futhi alungise wonke amaseli ephaketheni lebhethri. Emkhakheni wezimoto zamandla amasha, umsebenzi wayo osebenza kahle wokulinganisa uqinisekisa ukuthi iseli ngalinye lebhethri lingakwazi ukugcina isimo salo sokusebenza esiphelele, linciphise ngempumelelo ukulahlekelwa amandla okubangelwa amaseli ebhethri angahambisani, lithuthukise kakhulu ibanga lemoto, kuyilapho kunciphisa izingozi zokuphepha ezifana nokushisisa kwebhethri, nokuvikela uhambo lwakho oluluhlaza. Kubasebenzisi besikuta sikagesi, ukusebenzisa isilinganisi sebhethri lethu kungagcina ukuhambisana okuhle kwebhethri lakho lesikuta sikagesi ngaso sonke isikhathi, kunwebe impilo yebhethri, futhi kunciphise ubunzima nezindleko zokushintshwa kwebhethri njalo. Kungakhathaliseki ukuthi imoto yamandla entsha noma isikuta sikagesi, isilinganisi sebhethri yethu singakunikeza ukwesekwa kwamandla okuzinzile futhi okuhlala isikhathi eside ngokugcina ukungaguquguquki kwebhethri, okukuvumela ukuba ujabulele kalula uhambo olulula nokusebenzisa amandla ngendlela efanele. Ukukhetha isilinganisi sebhethri yethu kusho ukukhetha ukutshala imali kusiqinisekiso esinokwethenjelwa sebhethri lakho bese uqalisa isipiliyoni esisha sekhwalithi ephezulu sokusebenzisa ibhethri. .
