Amabhethri e-lithium adinga ukuvikelwa.Uma i18650 lithium ibhethriayinalo ibhodi lokuvikela, okokuqala, awukwazi ukuthi ibhethri ye-lithium ikhokhiswa kude kangakanani, futhi okwesibili, ayikwazi ukukhokhiswa ngaphandle kwebhodi lokuvikela, ngoba ibhodi lokuvikela kufanele lixhunywe kubhethri ye-lithium enezintambo ezimbili.Ungacabangi ukuthi ikhwalithi yebhethri ye-lithium oyithengile inhle ngaphandle kwebhodi lokuvikela, kodwa uma kuthatha isikhathi eside, izinkinga ezihlukahlukene zizokwenzeka.

Uma ishajwe ngokugcwele, ibhodi lokuvikela ibhethri le-lithium liwukuvikela ukushaja nokukhipha uchungechunge lwephakethe lebhethri le-lithium, elingaqinisekisa ukuthi umehluko we-voltage phakathi kwamabhethri ungaphansi kwenani elibekiwe, futhi lingafinyelela ibhalansi yebhethri ngalinye ebhethrini. iphakethe, ngaleyo ndlela ithuthukise ngempumelelo uchungechunge loxhumano Umphumela wokushaja kwimodi yokushaja.Ngesikhathi esifanayo, ingakwazi ukubona i-overvoltage, i-overcharge, i-overdischarge, i-short circuit kanye nokushisa okweqile kwebhethri okukhiqizwa yi-welder ngayinye ye-lithium yebhethri ephaketheni lebhethri ukuvikela nokwandisa impilo yebhethri.Ukuvikela i-under-voltage kungavimbela iseli ngalinye ukuthi lonakaliswe ukukhishwa ngokweqile ngesikhathi sokuphuma.

1. Ukukhetha ibhodi lokuvikela kanye nokushaja nokukhipha izindaba zokusebenzisa
(Idatha ngeye-ibhethri ye-lithium iron phosphate, isimiso sebhethri elivamile elingu-3.7v siyefana, kodwa idatha ihlukile)

Inhloso yebhodi lokuvikela ukuvikela ibhethri ekushajweni ngokweqile nasekuchitheni ngokweqile, ukuvikela amandla aphezulu ukuthi angalimazi ibhethri, kanye nokulinganisela ugesi webhethri lapho ishajwe ngokugcwele (ikhono lokulinganisa ngokuvamile lincane uma kuqhathaniswa, ngakho uma kukhona ibhodi lokuvikela ibhethri elizikhiphayo, linzima kakhulu Kunzima ukulinganisa, futhi kukhona namabhodi okuvikela abhalansi kunoma yisiphi isimo, okungukuthi, ibhalansi yenziwa kusukela ekuqaleni kokushaja, okubonakala kungavamile).

Ukuphila kwephakethe lebhethri, kunconywa ukuthi i-voltage yokushaja ibhethri ingeqi ku-3.6v nganoma yisiphi isikhathi, okusho ukuthi i-voltage yesenzo sokuvikela yebhodi lokuvikela ayikho ngaphezu kuka-3.6v, futhi i-voltage elinganiselwe inconywa ukuba I-3.4v-3.5v (iseli ngalinye elingu-3.4v likhokhiswe ngaphezu kuka-99 % Ibhethri, ibhekisela esimweni esimile, i-voltage izokhuphuka uma ishajwa ngamandla aphezulu).I-voltage yokuvikela ukukhishwa kwebhethri ngokuvamile ingaphezulu kuka-2.5v (ngaphezulu kwe-2v akuyona inkinga enkulu, ngokuvamile akuvamile ukuba nethuba lokuyisebenzisa iphelelwe amandla ngokuphelele, ngakho-ke le mfuneko ayiphezulu).

2. I-voltage ephezulu enconyiwe yeshaja (isinyathelo sokugcina sokushaja singaba imodi yokushaja kagesi engapheli) ingu-3.5*inani lezintambo, njengokuthi cishe u-56v ezintanjeni eziyi-16.Ngokuvamile ukushaja kunganqanyulwa ngesilinganiso esingu-3.4v ngeseli (ngokuyisisekelo sishajwe ngokugcwele), ukuze ukuphila kwebhethri kuqinisekiswe, kodwa ngenxa yokuthi ibhodi lokuvikela alikaqali ukulinganisela, uma umgogodla webhethri unokuzikhulula okukhulu. , izoziphatha njengeqembu lonke ngokuhamba kwesikhathi Umthamo uyancipha kancane kancane.Ngakho-ke, kuyadingeka ukushaja ibhethri ngalinye ku-3.5v-3.6v njalo (isibonelo masonto onke) futhi uyigcine amahora ambalwa (inqobo nje uma isilinganiso sikhulu kunokulinganisa kokuqala kwe-voltage), kukhulu ukuzikhipha, uma ukulinganisa kuzothatha isikhathi eside, futhi ukuzikhipha kwamaseli Amakhulu anzima ukulinganisa futhi adinga ukuqedwa.Ngakho-ke lapho ukhetha ibhodi lokuvikela, zama ukukhetha ukuvikela kwe-3.6v overvoltage, bese uqala ukulinganisa cishe ku-3.5v.(Iningi lokuvikelwa kwe-overvoltage emakethe lingaphezulu kuka-3.8v, futhi ukulingana kuqalwe ngaphezu kuka-3.6v).Eqinisweni, ukukhetha i-voltage efanelekayo yokuqala elinganisiwe kubaluleke kakhulu kune-voltage yokuvikela, ngoba i-voltage ephezulu ingashintshwa ngokulungisa umkhawulo ophezulu wamandla kagesi weshaja (okungukuthi, ibhodi lokuvikela ngokuvamile alinalo ithuba lokuvikela amandla kagesi aphezulu. ), kodwa uma i-voltage elinganisiwe iphezulu, iphakethe lebhethri alinalo ithuba lokulinganisa (ngaphandle uma I-voltage yokushaja inkulu kune-voltage yokulinganisa, kodwa lokhu kuthinta impilo yebhethri), iseli yebhethri izokwehla kancane kancane ngenxa yokuzikhipha. umthamo (iseli elifanele elizikhiphayo elingu-0 alikho).

3. Ukukhishwa okuqhubekayo kwamandla amanje ebhodi lokuvikela.Lena into embi kakhulu ongaphawula ngayo.Ngoba amandla amanje okukhawulela ibhodi lokuvikela alisho lutho.Isibonelo, uma uvumela ishubhu engu-75nf75 ukuthi iqhubeke idlule ku-50a yamanje (ngalesi sikhathi, amandla okushisa acishe abe ngu-30w, okungenani ama-60w amabili ochungechungeni ebhodini lembobo elifanayo), inqobo nje uma kukhona isinki sokushisa esanele sokuhlakazeka. ukushisa, akunankinga.Ingagcinwa ku-50a noma ngaphezulu ngaphandle kokushisa ithubhu.Kodwa awukwazi ukusho ukuthi leli bhodi lokuvikela lingahlala i-50a yamanje.Ngoba amapuleti amaningi okuvikela awo wonke umuntu afakwa ebhokisini lebhethri eduze kakhulu nebhethri, noma avale.Ngakho izinga lokushisa eliphezulu elinjalo lizoshisa ibhethri futhi lishise.Inkinga ukuthi izinga lokushisa eliphezulu yisitha esibulalayo sebhethri.

Ngakho-ke, indawo yokusetshenziswa kwebhodi lokuvikela inquma indlela yokukhetha umkhawulo wamanje (hhayi umthamo wamanje webhodi lokuvikela ngokwalo).Uma ibhodi lokuvikela likhishwa ebhokisini lebhethri, cishe noma yiliphi ibhodi lokuvikela elinomshini wokushisa lingakwazi ukuphatha i-50a yamanje eqhubekayo noma ngaphezulu (ngalesi sikhathi, umthamo webhodi lokuvikela kuphela ucatshangelwa, futhi asikho isidingo sokukhathazeka mayelana ukunyuka kwezinga lokushisa okubangela ukulimala kwamaseli).Ake sikhulume ngendawo esetshenziswa yiwo wonke umuntu, esesikhaleni esivalekile njengebhethri.Ngalesi sikhathi, amandla okushisa aphezulu ebhodi lokuvikela alawulwa kangcono ngaphansi kwe-10w (uma ibhodi elincane lokuvikela, lidinga i-5w noma ngaphansi, futhi ibhodi lokuvikela ivolumu elikhulu lingaba ngaphezu kwe-10w, ngoba linokushisa okuhle. ukuchithwa kanye nezinga lokushisa ngeke libe phezulu kakhulu).Ngokuqondene nokuthi kungakanani okufanele, okuqhubekayo okwamanje kunconywa Uma izinga lokushisa eliphezulu lebhodi lonke lingadluli ama-degrees angu-60 (okungcono kakhulu ngaphansi kwama-50 degrees).Ngokweqile, izinga lokushisa eliphansi lebhodi lokuvikela, lingcono, futhi lizothinta kancane amaseli.

4. Umehluko phakathi kwebhodi lechweba elifanayo nebhodi lechweba elihlukile: ibhodi lechweba elifanayo liwumugqa ofanayo wokushaja nokukhipha, futhi kokubili ukushaja nokukhipha kuvikelekile.

Ibhodi lechweba elihlukile lizimele emugqeni wokushaja kanye nolayini wokukhulula.Imbobo yokushaja ivikela kuphela ekushajeni uma ishaja, futhi ayivikeli uma ikhishwa embobeni yokushaja (kodwa ingaphuma ngokuphelele, kodwa umthamo wamanje wembobo yokushaja ngokuvamile mancane uma kuqhathaniswa).Imbobo yokukhipha ivikela ekukhishweni ngokweqile ngesikhathi sokukhipha.Uma ukushajwa kusuka kumbobo yokukhipha, ukushaja ngokweqile akuvikelekile (ngakho ukushajwa okuhlanekezelwe kwe-ecpu kungasetshenziswa ngokuphelele ebhodini lembobo ehlukile. Futhi ukushajwa okuphambene kuncane kakhulu kunamandla asetshenzisiwe, ngakho-ke Ungakhathazeki ngokushaja ngokweqile ibhethri ngenxa yokushajwa ngokuhlehla.

Bala ubuningi bamanje obuqhubekayo bemoto yakho, khetha ibhethri elinamandla afanelekile noma amandla angahlangabezana nalokhu kugeleza okuqhubekayo futhi izinga lokushisa liyalawulwa.Okuncane ukumelana kwangaphakathi kwebhodi lokuvikela, kungcono.Ukuvikela okudlulele kwebhodi lokuvikela empeleni kudinga kuphela ukuvikelwa kwesekethe emfishane kanye nokunye ukuvikela ukusetshenziswa okungavamile.
Isifinyezo: Ukusetshenziswa kwamabhethri e-lithium kudinga ukulawula izinga lokushisa eliphezulu (ukwenyuka kwezinga lokushisa okubangelwa ukukhishwa okuphezulu kwamanje noma okubangelwa indawo ezungezile), nokulawula umkhawulo kagesi wokushaja kanye nomthamo omncane wokukhipha amandla (okuzogcwaliswa ngebhodi lokuvikela kanye neshaja ).Kungcono ukugcina ibhethri ku-voltage yesikhulumi (cishe i-3.25-3.3v ye-lithium iron phosphate) uma ingasetshenziswa.

Ukunciphisa ukumelana kwangaphakathi kwebhodi lokuvikela, kungcono, futhi kunciphise ukumelana kwangaphakathi, ukushisa okuncane.Umkhawulo wamanje webhodi lokuvikela unqunywa ukuphikiswa kwesampula yocingo lwethusi, kodwa amandla amanje aqhubekayo anqunywa yi-mos (ngoba ukumelana kwangaphakathi kwe-mos kunquma ukuphakama kwezinga lokushisa).
