Isingeniso:
Emkhakheni wokulungisa ibhethri, ukuhambisana kwephakethe lebhethri kuyisici esibalulekile, esithinta ngqo impilo yesevisi yamabhethri e-lithium. Kodwa lokhu kuvumelana kubhekisela kuphi ngempela, futhi kungahlulelwa kanjani ngokunembile? Isibonelo, uma kukhona umehluko ngomthamo phakathi kwamabhethri, ungakanani umehluko okufanele ulawulwe ngendlela efanele? Lokhu kubalulekile ngoba kuthinta ukuthi ibhethri lakho le-lithium lingahlala isikhathi esingakanani.
Ukuvumelana kwamabhethri kungumqondo obaluleke kakhulu emkhakheni wamabhethri. Kalula nje, uma ukuhambisana kwephakethe lebhethri kungcono, kulapho lingashaja noma likhulule khona kakhulu, futhi izinga lokusetshenziswa lilonke lephakethe lebhethri nalo lizothuthukiswa kakhulu. Ngokukhethekile, ukuhambisana kwebhethri kuhlanganisa izici eziyisishiyagalombili eziyinhloko, okungukuthi i-voltage, umthamo, ukumelana kwangaphakathi, isilinganiso samanje esingaguquki, i-discharge plateau, impilo yomjikelezo, i-SOC charge, kanye nezinga lokukhipha amandla. Njengoba kuyinkimbinkimbi yencazelo yonke, sizogxila ekuhlaziyeni izinto ezintathu ezibalulekile okulula ukuzilawula nokuzahlulela.
Ukungaguquguquki kwamabhethri
Ukuvumelana kwamabhethri kungumqondo obaluleke kakhulu emkhakheni wamabhethri. Kalula nje, uma ukuhambisana kwephakethe lebhethri kungcono, kulapho lingashaja noma likhulule khona kakhulu, futhi izinga lokusetshenziswa lilonke lephakethe lebhethri nalo lizothuthukiswa kakhulu. Ngokukhethekile, ukuhambisana kwebhethri kuhlanganisa izici eziyisishiyagalombili eziyinhloko, okungukuthi i-voltage, umthamo, ukumelana kwangaphakathi, isilinganiso samanje esingaguquki, i-discharge plateau, impilo yomjikelezo, i-SOC charge, kanye nezinga lokukhipha amandla. Njengoba kuyinkimbinkimbi yencazelo yonke, sizogxila ekuhlaziyeni izinto ezintathu ezibalulekile okulula ukuzilawula nokuzahlulela.
Ukuvumelana kwamandla kagesi
Okokuqala, ukuhambisana kwamandla kagesi. Ikakhulukazi ngaphambi kokuhlanganisa amabhethri e-lithium, kubalulekile ukuqinisekisa ukuthi amandla kagesi phakathi kweseli ngalinye ahambisana ngokuphelele. Ensimini yokugcina amandla yesivinini esiphansi noma ye-civil, ngokuvamile kubhekwa njengokuhlangabezana nezindinganiso zokulawula ngokuqinile inani lamaphutha kagesi ngaphakathi kwama-millivolts ama-5. Yingakho futhi ukulinganisa ngokucophelela amandla kagesi eseli kuyisinyathelo esiyinhloko nesibalulekile ngaphambi kokuhlanganisa amabhethri e-lithium. Isibonelo, ephaketheni lebhethri elakhiwe ngamaseli amaningi ebhethri, uma ukuphambuka kwamandla kagesi kweseli elilodwa lebhethri kwamanye kudlula ama-millivolts ama-5, iseli lebhethri lingase libhekane nokushaja ngokweqile noma ukushaja ngaphansi ngesikhathi senqubo yokushaja. Ngokuhamba kwesikhathi, lokhu akuthinti nje kuphela ukusebenza okuphelele kwephakethe lebhethri, kodwa futhi kunciphisa kakhulu impilo yalo yesevisi.
Ukuvumelana kwamandla
Okwesibili, usayizi womthamo phakathi kweseli ngayinye yebhethri kufanele ugcinwe ufana ngangokunokwenzeka. Esimweni esifanele, umthamo weseli ngayinye yebhethri akufanele uhluke, kodwa ekukhiqizweni nasekusetshenzisweni kwangempela, kunzima kakhulu ukufeza ukuvumelana okuphelele. Ngakho-ke, inani lamaphutha lomthamo livame ukulawulwa cishe ku-2% ngangokunokwenzeka. Yiqiniso, eqenjini lamabhethri, kuyamukeleka ukuthi amaseli ngamanye abe nomthamo ophakeme kancane, kodwa ekusetshenzisweni kwangempela, kufanele aphathwe ngokwezindinganiso zamaseli anamandla aphansi. Isibonelo, ohlelweni lwebhethri lwama-volt angu-48 oluqukethe amaseli ebhethri axhunyiwe ochungechungeni lwe-16, lapho umthamo wamaseli angu-15 ufana khona, futhi umthamo weseli le-16 uphakeme kancane, umthamo wangempela otholakalayo wephakethe lebhethri lonke kufanele usekelwe kumthamo ophansi wala maseli angu-15. Ngenxa yokuthi ugesi uyafana ephaketheni lebhethri elixhunyiwe ochungechungeni, uma lishajwa futhi likhishwa ngokwezindinganiso zamaseli anamandla aphezulu, amaseli anamandla aphansi angonakala ngenxa yokushaja nokukhipha ngokweqile, ngaleyo ndlela kuthinte ukusebenza kanye nokuphila kwesikhathi sephakethe lebhethri lonke.
Ukungaguquguquki kokumelana kwangaphakathi
Into yokugcina okufanele sikhulume ngayo ukumelana kwangaphakathi. Umehluko ekumelaneni kwangaphakathi phakathi kweseli ngayinye ephaketheni lebhethri kufanele uncishiswe, futhi ngokuvamile kufanelekile ukuyilawula ngaphakathi kuka-15%. Umehluko omncane ekumelaneni kwangaphakathi unganciphisa ngempumelelo isimo sokungalingani kwamabhethri ngesikhathi sokushaja nokukhipha ishaja. Iphakethe lebhethri elinokuqina okuhle kokumelana kwangaphakathi linganciphisa kakhulu ukulahleka kwamandla kanye nokukhiqizwa kokushisa ngesikhathi sokushaja nokukhipha ishaja. Uma sithatha iphakethe lebhethri lezimoto zikagesi njengesibonelo, uma ukuqina kokumelana kwangaphakathi kwamaseli ebhethri kukubi, ngesikhathi sokushaja okusheshayo, amaseli anokumelana okuphezulu kwangaphakathi azokhiqiza ukushisa okwengeziwe, okungagcini nje ngokunciphisa ukusebenza kahle kokushaja, kodwa futhi okungase kubangele izingozi zokuphepha njengokushisa ngokweqile nomlilo. Lapho ukuqina kokumelana kwangaphakathi kuqinisekisiwe, ukusebenza kahle kokushaja nokukhipha ishaja kwephakethe lebhethri kungathuthukiswa, futhi ukuphepha kungathuthukiswa kakhulu.
Isilinganisi sebhethri seHeltec
Ngamafuphi, enkambisweni yokulungisa, ukuhlanganisa, kanye nokusebenzisa amabhethri, kubalulekile ukunaka ngokugcwele nokulawula ngokuqinile ukuhambisana kwebhethri, ikakhulukazi ezicini ezintathu ezibalulekile ze-voltage, umthamo, kanye nokumelana kwangaphakathi, ukuze kwandiswe impilo yebhethri futhi kuthuthukiswe ukusebenza kwebhethri.
Ohambweni lokuqinisekisa ukuhambisana kwebhethri,ibhalansi yebhethriingabhekwa njengomsizi onokwethenjelwa, ofanele izimoto zamandla ezintsha namabhethri ezimoto zikagesi, futhi ingaqapha futhi ilungise ngokunembile yonke iseli ephaketheni lebhethri. Emkhakheni wezimoto zamandla ezintsha, umsebenzi wayo wokulinganisela osebenzayo uqinisekisa ukuthi iseli ngayinye yebhethri ingagcina isimo sayo sokusebenza esifanele, inciphise ngempumelelo ukulahleka kwamandla okubangelwa amaseli ebhethri angaguquki, ithuthukise kakhulu ububanzi bemoto, ngenkathi inciphisa izingozi zokuphepha njengokushisa ngokweqile kwebhethri, futhi ivikele uhambo lwakho oluluhlaza. Kubasebenzisi besikuta sikagesi, ukusebenzisa ibhalansi yethu yebhethri kungagcina ukuhambisana okuhle kwebhethri lakho lesikuta sikagesi ngaso sonke isikhathi, kwandise impilo yebhethri, futhi kunciphise ubunzima nezindleko zokushintsha ibhethri njalo. Kungakhathaliseki ukuthi imoto entsha yamandla noma isikuta sikagesi, ibhalansi yethu yebhethri ingakunikeza ukwesekwa kwamandla okuzinzile nokuhlala isikhathi eside ngokugcina ukuhambisana kwebhethri, okukuvumela ukuthi ujabulele kalula ukuhamba okulula nokusetshenziswa kwamandla okuphumelelayo. Ukukhetha ibhalansi yethu yebhethri kusho ukukhetha ukutshala imali esiqinisekisweni esithembekile sebhethri lakho bese uqala ulwazi olusha olusezingeni eliphezulu lokusebenzisa ibhethri.
