Ukalo lwe-Ah oluqhelekileyo lweZixhobo ezahlukeneyo
Ngoku njengoko siqonda ukuba i-Ah ikuchaphazela njani ukusebenza kwebhetri, makhe sijonge ezinye iireyithingi ze-Ah zezixhobo ezahlukeneyo. Loluphi uhlobo lwezakhono ze-Ah onokulindela ukuzifumana kwi-elektroniki yemihla ngemihla kunye neenkqubo ezinkulu zamandla?
Ii-smartphones:
Uninzi lwee-smartphones zanamhlanje zineebhetri ukusuka kwi-3,000 ukuya kwi-5,000 mAh (3-5 Ah). Umzekelo:
- I-iPhone 13: 3,227 mAh
- I-Samsung Galaxy S21: 4,000 mAh
Izithuthi zoMbane:
Iibhetri ze-EV zikhulu kakhulu, zihlala zilinganiswa ngee-kilowatt-yure (kWh):
- I-Tesla Model 3: 50-82 kWh (ilingana malunga ne-1000-1700 Ah kwi-48V)
- BYD HAN EV: 50-76.9 kWh (ngokumalunga ne-1000-1600 Ah ku-48V)
Ugcino lwamandla elanga:
Kwigridi kunye neenkqubo zamandla ezigcinayo, iibhetri ezinokalisho oluphezulu lwe-Ah ziqhelekile:
- BSLBATT12V 200Ah Ibhetri yeLithium: Ilungele ukufakwa kwamandla elanga amancinci naphakathi njengokugcinwa kwamandla eRV kunye nokugcinwa kwamandla elwandle.

I-smartphone idinga ukuhlala usuku okanye ezimbini kwintlawulo, ngelixa inkqubo yebhetri yelanga inokufuna ukunika amandla ikhaya kangangeentsuku ezininzi ngexesha lemozulu enamafu.
Cinga ngalo mzekelo wehlabathi lokwenyani kumthengi we-BSLBATT: “Ndiphucule ukusuka kwi-100 Ah ibhetri ye-lead-acid ukuya kwi-100 Ah ibhetri ye-lithium ye-RV yam. Andizange ndifumane umthamo osebenzisekayo kuphela, kodwa ibhetri ye-lithium iphinde ihlawule ngokukhawuleza kwaye igcinwe i-voltage engcono phantsi komthwalo. Ingathi ndiyiphindaphinde kabini i-Ah yam esebenzayo!”
Ke, kuthetha ukuthini oku xa uthengela ibhetri? Ungawubona njani umlinganiselo we-Ah ochanekileyo kwiimfuno zakho? Makhe siphonononge iingcebiso ezisebenzayo zokukhetha elona xabiso lifanelekileyo lebhetri kwicandelo elilandelayo.
Ukubala ibhetri yeXesha lokuSebenza usebenzisa i-Ah
Ngoku siphonononge iireyithingi eziqhelekileyo zika-Ah zezixhobo ezahlukeneyo, usenokuba uyazibuza: “Ndingalusebenzisa njani olu lwazi ukubala ukuba ibhetri yam iya kuhlala ixesha elingakanani?” Lo ngumbuzo ogqwesileyo, kwaye ubalulekile ekucwangciseni iimfuno zakho zamandla, ngakumbi kwiimeko ezingaphandle kwegrid.
Masiyicalule inkqubo yokubala ixesha lebhetri usebenzisa Ah:
1. Ifomula esisiseko:
Ixesha lokubaleka (iiyure) = Umthamo webhetri (Ah) / umzobo wangoku (A)
Umzekelo, ukuba unebhetri ye-100 Ah enika amandla isixhobo esitsala ii-amps ezi-5:
Ixesha lokusebenza = 100 Ah / 5 A = iiyure ezingama-20
2. Uhlengahlengiso Lwehlabathi Lokwenyani:
Nangona kunjalo, olu balo lulula aluchazi lonke ibali. Ekusebenzeni, kufuneka uqwalasele izinto ezifana:
Ubunzulu bokukhutshwa (DoD): Iibhetri ezininzi akufuneki zikhutshwe ngokupheleleyo. Kwiibhetri ze-lead-asidi, usebenzisa kuphela i-50% yomthamo. Iibhetri zeLithium, ezifana nezo zisuka kwi-BSLBATT, zihlala zikhutshwa ukuya kuthi ga kwi-80-90%.
Umbane: Njengoko iibhetri ziphuma, amandla ombane azo ahla. Oku kunokuchaphazela umzobo wangoku wezixhobo zakho.
Umthetho wePeukert: Oku kubalela into yokuba iibhetri ziye zingasebenzi kakuhle kumazinga aphezulu okukhutshwa.
3. Umzekelo osebenzayo:
Masithi usebenzisa i-BSLBATTI-12V 200Ah ibhetri ye-lithiumukunika amandla isibane se-50W LED. Nantsi indlela ongalibala ngayo ixesha lokusebenza:
Inyathelo 1: Bala umzobo wangoku
Okwangoku (A) = Amandla (W) / Voltage (V)
Okwangoku = 50W / 12V = 4.17A
Inyathelo lesi-2: Faka ifomula nge-80% ye-DoD
Ixesha lokuqhuba = (Umthamo webhetri x DoD) / Idro yangoku\nIxesha lokuqhuba = (100Ah x 0.8) / 4.17A = 19.2 iiyure
Umthengi we-BSLBATT wabelane: "Bendihlala ndisokola ngokuqikelela ixesha lokusebenza kwekhabhathi yam engaphandle kwegrid. Ngoku, ngezi zibalo kunye nebhanki yam ye-lithium ye-200Ah, ndingacwangcisa ngokuzithemba iintsuku ezi-3-4 zamandla ngaphandle kokutshaja kwakhona.
Kodwa kuthekani ngeenkqubo ezintsonkothileyo ezinezixhobo ezininzi? Ungaphendula njani ngokutsala amandla okwahlukileyo imini yonke? Kwaye ngaba kukho naziphi na izixhobo ukwenza lula ezi zibalo?
Khumbula, ngelixa ezi zibalo zibonelela ngoqikelelo olulungileyo, ukusebenza kwelizwe lokwenyani kunokwahluka. Kuhlala kububulumko ukuba nesithinteli kwisicwangciso sakho samandla, ngakumbi kwizicelo ezibalulekileyo.
Ngokuqonda indlela yokubala ixesha lebhetri usebenzisa i-Ah, ukuxhotyiswe ngcono ukuba ukhethe umthamo webhetri ofanelekileyo kwiimfuno zakho kwaye ulawule ukusetyenziswa kwamandla akho ngokufanelekileyo. Nokuba ucwangcisa uhambo lokuhlala enkampini okanye uyila isixokelelwano selanga sasekhaya, ezi zakhono ziya kukunceda kakuhle.
Ah vs. Eminye imilinganiselo yebhetri
Ngoku siphononongileyo ukubala ixesha lokusebenza kwebhetri usebenzisa i-Ah, usenokuba uyazibuza: “Ngaba zikhona ezinye iindlela zokulinganisa umthamo webhetri? Injani i-Ah xa ithelekiswa nezi ndlela zihlukileyo?"
Ewe, i-Ah ayisiyiyo kuphela i-metric esetyenziselwa ukuchaza umthamo webhetri. Eminye imilinganiselo emibini eqhelekileyo yile:
1. IiWatt-yure (Wh):
I-Wh ilinganisa umthamo wamandla, ukudibanisa zombini i-voltage kunye neyangoku. Ibalwa ngokuphindaphinda i-Ah ngombane.
Umzekelo:A 48V 100Ah ibhetriinomthamo we-4800Wh (48V x 100Ah = 4800Wh)
2. Iiyure zeMilliamp (mAh):
Le yi-Ah echazwe kwiwaka.1Ah = 1000mAh.
Ngoko kutheni usebenzisa imilinganiselo eyahlukileyo? Yaye ufanele unikele ingqalelo nini kwinto nganye?
Oku kuluncedo ngakumbi xa kuthelekiswa iibhetri zombane ezahlukeneyo. Umzekelo, ukuthelekisa ibhetri ye-48V 100Ah kunye nebhetri ye-24V 200Ah kulula ngokwemigaqo ye-Wh-zombini ziyi-4800Wh.
I-mAh iqhele ukusetyenziselwa iibhetri ezincinci, njengezo zikwii-smartphones okanye iitafile. Kulula ukufunda “3000mAh” kuno-“3Ah” kuninzi lwabathengi.
Iingcebiso zokuKhetha ibhetri eLungileyo esekwe kwi-Ah
Xa kuziwa ekukhetheni ibhetri eyiyo kwiimfuno zakho, ukuqonda iireyithingi zika-Ah kubalulekile. Kodwa unokulusebenzisa njani olu lwazi ukuze wenze olona khetho lufanelekileyo? Makhe siphonononge iingcebiso ezisebenzayo zokukhetha ibhetri elungileyo esekwe kwi-Ah.
