Njengoba igiya likagesi liqhubeka likhuphuka isikebhe sesimanje sesikebhe kufika isikhathi lapho ibhange lebhethri lidinga ukunwetshwa ukuze libhekane nezidingo ezikhulayo zamandla.
Kusejwayelekile ukuthi izikebhe ezintsha zifike nebhethri elincane lokuqalisa injini kanye nebhethri elincane kakhulu lenkonzo yomthamo - into ezovele isebenzise isiqandisi esincane amahora angu-24 ngaphambi kokuthi izodinga ukushajwa kabusha.Engeza kulokhu ukusetshenziswa kwezikhathi ezithile kwe-windlass yehange kagesi, izibani, amathuluzi okuzulazula kanye nomshayeli ozenzakalelayo futhi uzodinga ukusebenzisa injini njalo ngemva kwamahora ayisithupha noma ngaphezulu.
Ukwandisa umthamo webhange lakho lebhethri kuzokuvumela ukuthi uhambe isikhathi eside phakathi kwezindleko, noma umbe ujule endaweni oyibekile uma kunesidingo, kodwa kuningi okufanele ukucabangele kunezindleko zebhethri elengeziwe: kubalulekile ukucabangela indlela yokushaja kanye nokushaja. noma ngabe udinga ukuthuthukisa ishaja yakho yamandla ogwini, i-alternator noma amanye amajeneretha kagesi.

Udinga amandla angakanani?

Ngaphambi kokuthi ucabange ukuthi uzodinga amandla engeziwe lapho wengeza izinto zikagesi, kungani ungaqali wenze ucwaningo olunzulu lwezidingo zakho.Ngokuvamile ukubuyekezwa okujulile kwezidingo zamandla ebhodini kungaveza ukongiwa kwamandla okungenzeka kwenze kungadingeki ukungeza umthamo owengeziwe kanye nokwanda okuhlobene namandla okushaja.

Ukuqonda umthamo
Imonitha ingakusiza ukuthi ugcine amaleveli ebhethri anempilo impilo ende yebhethri
Isikhathi esifanele sokucabanga ukungeza elinye ibhethri yilapho usuzoshintsha elikhona.Ngaleyo ndlela uzobe uqala kabusha ngawo wonke amabhethri amasha, okuyinto ehlala ilungile – ibhethri elidala lingakwazi ukuhudulela phansi elisha njengoba lifinyelela ekupheleni kwempilo yalo.

Futhi, lapho ufaka ibhange lasekhaya elinamabhethri amabili (noma ngaphezulu) kunengqondo ukuthenga amabhethri anomthamo ofanayo.Isilinganiso se-Ah esivame ukuboniswa kumabhethri ezokungcebeleka noma omjikelezo ojulile sibizwa ngokuthi isilinganiso sawo se-C20 futhi sibhekisela kumthamo waso wethiyori uma sishajwa esikhathini esingamahora angu-20.
Amabhethri okuqalisa injini anamapuleti azacile okubhekana nokuqhuma okufushane kwamanje futhi avame ukukalwa kusetshenziswa ikhono lawo le-Cold Cranking Amps (CCA).Lezi azifanele ukusetshenziswa ebhange lesevisi njengoba zifa ngokushesha uma ngokuvamile zikhishwa ngokujulile.
Amabhethri angcono kakhulu azosetshenziswa ekhaya azolebulwa ngokuthi 'deep-cycle', okusho ukuthi azoba namapuleti awugqinsi aklanyelwe ukuletha amandla awo kancane futhi ngokuphindaphindiwe.

Ukwengeza ibhethri elengeziwe 'ngokuhambisanayo'
Kusistimu engu-12V ukungeza ibhethri elengeziwe kumane nje kuyisimo sokuyikhweza eduze kakhulu kwamabhethri akhona bese ixhuma ngokuhambisanayo, ixhuma amatheminali 'afana' (okuphozithivu ukuya kokuphozithivu, okunegethivu ukuya kokunegethivu) usebenzisa ikhebuli enkulu yobubanzi (ngokuvamile engu-70mm² diameter) kanye namatheminali ebhethri aboshwe ngendlela efanele.
Ngaphandle uma unamathuluzi kanye nekhebula elikhulu elilengayo ngingaphakamisa ukuthi ulinganise futhi wenze izixhumanisi eziphambanayo zenziwe ngobungcweti.Ungathenga i-crimper (ngokungangabazeki i-hydraulic iyona engcono kakhulu) kanye namatheminali ukuze uzenzele ngokwakho, kodwa ukutshalwa kwezimali komsebenzi omncane kangako ngokuvamile kuvame ukunqabela.
Uma uxhuma amabhethri amabili ngokuhambisana kubalulekile ukuqaphela ukuthi i-voltage ephumayo yebhange izohlala injalo, kodwa umthamo wakho otholakalayo (Ah) uzokhula.Kuvame ukudideka ngama-amps nama-amp amahora.Kalula nje, i-amp isilinganiso sokugeleza kwamanje, kanti i-amp hour iyisilinganiso sokugeleza kwamanje njalo ngehora.Ngakho-ke, ngokombono ibhethri elingu-100Ah (C20) linganikeza i-20A yamanje amahora amahlanu ngaphambi kokuba isicaba.Empeleni ngeke, ngenxa yezizathu eziningi eziyinkimbinkimbi, kodwa ukuze kube lula ngizoyiyeka ime.

Ixhuma amabhethri amasha 'ochungechungeni'
Uma ubungahlanganisa amabhethri amabili e-12V ndawonye ochungechungeni (emihle ukuya kwenegethivu, uthatha okukhiphayo kumatheminali esibili okuthi +ve kanye ne- -ve), ubuzoba nokukhiphayo okungu-24V, kodwa akukho mthamo owengeziwe.Amabhethri amabili e-12V/100Ah axhunywe ochungechungeni asazonikeza umthamo we-100Ah, kodwa ku-24V.Ezinye izikebhe zisebenzisa isistimu engu-24V kumadivayisi omthwalo osindayo njengezibuko zomoya, amawintshi, abenzi bamanzi namaphampu amakhulu ebhilige noma eshawa ngenxa yokuthi ukuphinda kabili amandla kagesi kuhhafu ukudonsa kwamanje kwedivayisi efanayo elinganiselwe amandla.
Ukuvikelwa nge-fuse yamanje ephezulu
Amabhange ebhethri kufanele ahlale evikelwe ngamafuse amanje aphezulu (c. 200A) kukho kokubili amatheminali aphumayo avumayo noma angalungile, futhi aseduze namatheminali ngangokunokwenzeka, kungabikho ukususwa kwamandla kuze kube ngemva kwefuse.Amabhulokhi e-fuse akhethekile atholakalayo ngale njongo, aklanywe ukuze kungabikho lutho olungaxhunywa ngqo ebhethri ngaphandle kokudabula i-fuse.Lokhu kunikeza ukuvikeleka okuphezulu kuma-short-circuits ebhethri, angabangela umlilo kanye/noma ukuqhuma uma kuyekwa kungavikelekile.

Yiziphi izinhlobo zamabhethri ahlukene?
Wonke umuntu unolwazi lwakhe kanye nethiyori mayelana nokuthi yiluphi uhlobo lwebhethri olulungele ukusetshenziswa ku-osolwandleimvelo.Ngokwesiko, bekungamabhethri amakhulu futhi asindayo avulekile agcwele i-lead-acid (FLA), futhi abaningi basafunga ngalobu buchwepheshe obulula.Izinzuzo ukuthi ungawagcwalisa ngamanzi acwecwe kalula futhi uhlole umthamo weseli ngalinye usebenzisa i-hydrometer.Isisindo esinzima sasho ukuthi abaningi bakhe ibhange labo lesevisi ngamabhethri angu-6V, okulula ukuwasebenzisa.Lokhu kusho nokuthi kuncane okumelwe kulahleke uma iseli elilodwa lehluleka.
Isigaba esilandelayo ngamabhethri e-lead-acid (i-SLA), abaningi abawancamelayo ngenxa yokuthi 'akukho kugcinwa' kanye nezimfanelo zabo ezingachitheki, nakuba engakwazi ukushajwa ngamandla njengebhethri yeseli evulekile ngenxa yekhono lawo lokusebenzisa kuphela ibhethri. khulula umfutho wegesi owedlulele esimweni esiphuthumayo.
Emashumini ambalwa eminyaka edlule kwasungulwa amabhethri ejeli, lapho i-electrolyte yayiyijeli eqinile kunokuba ibe uketshezi.Nakuba zivaliwe, zinganakekeli futhi zikwazi ukuhlinzeka ngenani elikhulu lemijikelezo yokushaja/yokukhipha, kwakudingeka zikhokhiswe ngamandla amancane nangama-voltage aphansi kunama-SLA.
Muva nje, amabhethri e-Absorbed Glass Mat (AGM) asedume kakhulu ezikebheni.Ilula kunama-LA avamile futhi i-electrolyte yawo imuncwe ku-matting kunoketshezi lwamahhala, awadingi ukulungiswa futhi angafakwa kunoma iyiphi i-engeli.Bangakwazi futhi ukwamukela amandla aphezulu, ngaleyo ndlela bathathe isikhathi esincane ukushajwa, futhi basinde emijikelezweni eminingi emihle yokushaja/yokukhipha kunamaseli agcwele amanzi.Okokugcina, banezinga eliphansi lokuzikhulula, ngakho-ke bangashiywa ngaphandle kokushaja isikhathi esithile.
Intuthuko yakamuva ibandakanya amabhethri asuselwa ku-lithium.Abanye bafunga ngabo ngezindlela zabo ezihlukahlukene (i-Li-ion noma i-LiFePO4 evame kakhulu), kodwa kufanele ziphathwe futhi zigcinwe ngokucophelela kakhulu.Yebo, alula kakhulu kunanoma yiliphi elinye ibhethri lasolwandle kanye nezibalo zokusebenza ezihlaba umxhwele ezifunwayo, kodwa zibiza kakhulu futhi zidinga isistimu yokuphatha ibhethri yobuchwepheshe obuphezulu ukuze ihlale ishajiwe futhi, okubaluleke kakhulu, ibhalansile phakathi kwamaseli.
Into eyodwa ebaluleke kakhulu okufanele uyiqaphele lapho udala ibhange lesevisi elixhumene ukuthi wonke amabhethri kufanele abe uhlobo olufanayo.Awukwazi ukuhlanganisa i-SLA, i-Gel ne-AGM futhi ngokuqinisekile awukwazi ukuxhumanisa noma yikuphi kwalokhu nanoma iyiphiibhethri esekelwe i-lithium.
