Kusho ukuthini ukuthi i-ah ebhethrini? I-Ah imele i-Amp-hour noma i-Ampere-hour, futhi iyiyunithi elinganisa umthamo webhethri. Cabanga ngayo njengosayizi wethangi likaphethiloli lebhethri. Isilinganiso se-Ah esiphezulu sisho ukuthi ibhethri lingagcina amandla engeziwe futhi linike amandla amadivayisi akho isikhathi eside ngaphambi kokudinga ukushajwa kabusha.
Ukuqonda i-Ampere-hour (Ah)
I-Ampere-hour imelela inani lokushaja ibhethri elingakulethela ngokuhamba kwesikhathi. I-Ah eyodwa isho ukuthi ibhethri lingahlinzeka njalo nge-ampere eyodwa yamandla kagesi ihora elilodwa. Isibonelo, i-Ibhethri le-LiFePO4 elingu-100Ah, njengalabo esibachwepheshe kuboI-YouthPOWER, ingakhipha ama-amps angu-5 amahora angu-20, ama-amps angu-10 amahora angu-10, njalo njalo.
Kungani Isilinganiso Sehora Le-Ampere Sibalulekile?
Isilinganiso sebhethri se-Ampere-hour sibalulekile ngoba sibonisa ngqo impilo yebhethri nesikhathi sokusebenza. Kungakhathaliseki ukuthi usetha i-uhlelo lokugcina amandla elanga, ibhange lamandla le-RV, noma iyunithi yamandla eyisipele, ukwazi i-Ah kukusiza ukuthi unqume ukuthi ibhethri liyahlangabezana yini nezidingo zakho zamandla. Ibhethri le-Ah ephezulu lizohlinzeka ngamandla eyisipele amade.
Ah ngomongo wesitoreji samabhethri elanga
Ngobaizinhlelo zebhethri lelanga, isilinganiso se-Ah siyisici esibalulekile ekulinganisweni kwesistimu. Sikusiza ukubala ukuthi angakanani amandla elanga ongawagcina ukuze uwasebenzise ebusuku noma phakathi nezinsuku ezinamafu. Uma kuhlanganiswa ne-voltage yebhethri (V), unganquma umthamo wamandla ophelele ngamahora e-watt (Wh) usebenzisa ifomula:I-Voltage (V) x Amahora e-Ampere (Ah) = Amahora e-Watt (Wh)Lokhu kunikeza isithombe esiphelele samandla ebhethri.
Ukukhetha Amandla Ebhethri Afanele
Uma ukhetha ibhethri lelanga le-lithium, ikakhulukazi ibhethriIsitoreji sebhethri se-LiFePO4eyaziwa ngokuphila kwayo isikhathi eside kanye nokuqina komjikelezo webhethri, isilinganiso se-Ah kufanele sihambisane nokusetshenziswa kwamandla kwakho kwansuku zonke. Ukuze uthole ukusebenza kwebhethri okunokwethenjelwa nokuhlala isikhathi eside komjikelezo ojulile kuzinhlelo zokusebenza zamandla avuselelekayo, cabanga ngezinketho zekhwalithi ephezulu. Ku-I-YouthPOWER, umkhiqizi ohamba phambili wamabhethri elanga, sinikeza uhla lwamabhethri elanga e-LiFePO4 anamandla aphezulu aklanyelwe ukuletha ukusebenza kahle kwebhethri kanye nokuthembeka kwezidingo zakho zokugcina amandla.
Imibuzo Evame Ukubuzwa Mayelana Nebhethri Ah
Umbuzo 1. Uyini umehluko phakathi kuka-Ah no-Wh?
A1: I-Ah (ihora le-Ampere) ilinganisa ishaja kagesi ibhethri elingayibamba, njengomthamo wethangi likaphethiloli. I-Wh (ihora le-Watt) ilinganisa amandla aphelele ibhethri elingawaletha, kubalwa ngokuthiI-Voltage (V) x Ah. I-Wh ngokuvamile iyisilinganiso esinembile kakhulu samandla aphelele ngoba ibala i-voltage.
Umbuzo 2. Ingabe isilinganiso se-Ah esiphezulu sisho ibhethri elingcono?
A2:I-Ah ephezulu isho umthamo ophezulu kanye nesikhathi sokusebenza eside, okungcono uma udinga amandla engeziwe. Kodwa-ke, "okungcono" kuncike nakwezinye izici ezifana ne-chemistry yebhethri (isb., i-LiFePO4), impilo yomjikelezo, isisindo, nokuthi i-voltage yebhethri kanye nosayizi obonakalayo kuhambisana kahle kangakanani nohlelo lwakho lokusebenza oluthile.
Umbuzo 3. Ngidinga ama-Ah amangaki ohlelweni lwami lwamandla elanga?
A3: Bala inani lamandla akho asetshenziswa nsuku zonke ngamahora e-Watt (Wh). Bese usebenzisa ifomula ethi Ah = Wh / System Voltage ukuthola umthamo omncane we-Ah. Isibonelo, uma udinga i-5000Wh ku-uhlelo lwelanga lwe-48V, udinga isitoreji sebhethri okungenani esingu-5000Wh / 48V ≈ 104Ah. Faka njalo i-buffer engu-20-30% ukuze usebenze kahle futhi unwebe esikhathini esizayo.
Umbuzo 4. Kwenzekani ngesilinganiso se-Ah uma ngixhuma amabhethri ngesikhathi esifanayo?
A4:Uma uxhuma amabhethri amabili e-voltage efanayo ngesikhathi esifanayo, izilinganiso ze-Ah ziyanda, kuyilapho i-voltage ihlala ifana. Isibonelo, ukuxhuma amabhethri amabili e-12V 100Ah ngesikhathi esifanayo kukunika ibhange lebhethri le-12V 200Ah, okuphinda kabili amandla akho nesikhathi sakho sokusebenza.
