Ukucacisa "Ithangi Lokubasela": Ayini Amahora E-Amp (Ah)?
Ukucacisa "Ithangi Lokubasela": Ayini Amahora E-Amp (Ah)?
Cabanga ngesilinganiso sebhethri se-Amp-hora (Ah) esifana nosayizi wethangi likaphethiloli lemoto.
Incazelo: Amahora ama-Amp (Ah) ayiyunithi yokushaja kagesi. Ngokucacile, i-Amp-hora eyodwa inkokhelo edluliswa isaka elizinzile le-ampere eyodwa egeleza ihora elilodwa.
Lokho Ekumelelayo (kumongo Wamandla): Uma kuhlanganiswa amandla kagesi ebhethri (V), i-Ah isiza ukunquma inani eliphelele lamandla ibhethri elingawagcina.
- Amandla (amahora we-Watt, Wh) = Amahora ama-Amp (Ah) × Amandla kagesi (V)
I-ANALOGY:Uma i-Ah ingusayizi webhakede lamanzi (ingakanani amanzi elingabamba), I-Voltage ifana nomfutho wamanzi. Amandla aphelele ayinhlanganisela yosayizi webhakede nokucindezela.
Ngakho-ke, ibhethri elinesilinganiso sika-Ah esiphezulu, ngevolumu efanayo, lingaletha intambo ethile isikhathi eside, noma isimanje esiphezulu isikhathi esifushane, uma kuqhathaniswa nebhethri eliphansi le-Ah. Empeleni, i-Ah ikutshela ngokukhuthazela kwebhethri noma umthamo wesikhathi sokusebenza, hhayi ngokuqondile ukuphuma kwayo kwamandla ngaso leso sikhathi.
Ukuqonda "Injini": Yini Amandla Ebhethri (Watts)?
Uma u-Ah kuyithangi likaphethiloli, khona-ke Amandla (akalwa ngama-Watts, W) afana namandla enjini ehhashi - amandla ayo okwenza umsebenzi ngesikhathi esithile.
Incazelo: Amandla izinga amandla kagesi adluliswa noma adliwe ngaso.
I-Core Formula: Amandla (P) ibalwa ngokuphindaphinda I-Voltage (V) Ngamanje (I, ikalwa ngama-Amps):
-
Amandla (ama-Watts, W) = Amandla kagesi (V) × Amanje (Ama-Amps, A)
I-ANALOGY:Sisebenzisa ibhakede lethu lamanzi, Amandla afana nezinga amanzi angaphuma ngalo ebhakedeni (isb., amalitha ngomzuzu). Ibhakede elikhulu (eliphezulu u-Ah) aliqinisekisi ukugeleza okusheshayo uma i-outlet (emele amandla okukhipha ibhethri) incane.
Le fomula ngokushesha isitshela ukuthi I-Voltage kanye ne-Current (Amps) yangempela edwetshwayo yizici eziqondile zamandla, hhayi nje amahora angama-Amp.
Ngalé Kwamahora E-Amp: Izinto Ezibalulekile Ezinquma Okukhipha Amandla Ebhethri
Ukubheka nje isilinganiso sika-Ah ngeke kukutshele indaba ephelele mayelana namandla ebhethri. Ezinye izici eziningana zibaluleke kakhulu:
A. I-Voltage (V) – Isiphindaphinda Se-Power Equation
Njengoba kubonakala ku-P = V × I, i-voltage idlala indima eqondile nebalulekile,Umhlahlandlela ophelele weshadi le-LiFePO4 Voltage.
Umthelela: Kuwo wamanje ofanayo (ama-Amps), ibhethri elinamandla kagesi aphezulu lizoletha amandla engeziwe.
Isibonelo:
- Ibhethri 1:51.2V, 100Ah, ekwazi ukuletha i-50A. Amandla = 51.2V × 50A = 2560W.
- Ibhethri 2: 25.6V, 100Ah, elikwazi ukuletha u-50A. Amandla = 25.6V × 50A = 1280W.
Womabili amabhethri ane-Ah efanayo (umthamo wokugcina amandla wamanje onikeziwe ngokuhamba kwesikhathi uyafana uma sicabangela i-Wh), kodwa ibhethri engu-51.2V iletha amandla aphindwe kabili kuleyo 50A yamanje.
B. I-C-Rate (Isilinganiso Sokukhipha) – "I-Valve" Elawula Ukugeleza Kwamanje
Lokhu mhlawumbe okubaluleke kakhulu, kodwa okuvame ukunganakwa, isici esixhumanisa ngokuqondile u-Ah namandla angaba khona futhi ngaleyo ndlela,Ukuhlaziywa Okubanzi Kwesilinganiso Sebhethri ye-Lithium
Incazelo: I-C-rate ikhombisa ukuthi ibhethri lingashajwa ngokushesha kangakanani uma liqhathaniswa nomthamo walo usuwonke. Izinga le-1C lisho ukuthi ibhethri lingashajwa ngokuphelele ehoreni elingu-1. Izinga le-2C lisho ukuthi lingakhishwa emizuzwini engama-30 (kulethela kabili inani lamanje lesilinganiso esingu-1C). Izinga elingu-0.5C lisho ukuthi kuthatha amahora angu-2 (ukuletha uhhafu wamanje wezinga elingu-1C).
Ibala Ubuningi obuqhubekayo bamanje:
I-Max Continuous Current (Amps) = I-C-Rate × Amandla we-Amp-hora (Ah)
Umthelela Kumandla: I-C-rate ephezulu ivumela ibhethri ukuthi ilethe i-current ephezulu, okuthi, ngevolthi ethile, ihumushe emandleni aphezulu.
ISIBONELO:
- B-LFP48-100PW: 51.2 V, 100 Ah, 1C isilinganiso. Ubukhulu Bamanje = 1C × 100 Ah = 100 A. Amandla Amakhulu = 51.2 V × 100 A = 5120 W.
- I-B-LFP48-200PW:51.2 V, 200 Ah, 0.5C isilinganiso. Ubukhulu Bamanje = 0.5C × 200 Ah = 100 A. Amandla Amakhulu = 51.2 V × 100 A = 5120 W.
Ukubuka: I-B-LFP48-200PW ine-Ah ephindwe kabili (isitoreji samandla amaningi), kodwa ngenxa yezinga eliphansi le-C, ukukhishwa kwayo kwamandla aphezulu kuyafana nebhethri B-LFP48-100PW.
Amabhethri elanga e-BSLBATT LFP ajwayele ukwakhiwa ukuze enze isiphindaphinda sokuphindaphinda esingu-1C esiqhubekayo, awenze afanelekele izinhlelo zokusebenza zokugcina amandla elanga adinga kokubili ukuminyana okuhle kwamandla kanye nokuphuma kwamandla aphezulu.
C. Ukumelana Kwangaphakathi (IR) – Isela Lamandla Elingabonakali
Ibhethri ngalinye linokumelana okuthile kwangaphakathi.
Umthelela: Uma kugeleza kwamanje, ukumelana kwangaphakathi kubangela ukwehla kwamandla kagesi ngaphakathi kwebhethri (V_drop = I × R_internal). Lokhu kusho ukuthi i-voltage etholakala kumatheminali ebhethri (futhi ngaleyo ndlela amandla alethwa ocingweni lwakho) aphansi kunevoltheji yebhethri evula isekethe, ikakhulukazi kumaza aphezulu.
Ukumelana okuphezulu kwangaphakathi kuholela ekulahlekeni kwamandla engeziwe njengokushisa ngaphakathi kwebhethri kanye nokuncipha kokukhishwa kwamandla asebenzayo. Amabhethri okugcina amandla ekhwalithi, njengamamodeli amaningi e-BSLBATT, adizayinelwe anokumelana okuphansi kwangaphakathi ukuze kukhuliswe ukulethwa kwamandla nokusebenza kahle.
D. Uhlelo Lokuphatha Ibhethri (BMS) – I-Intelligent Power Guardian
Amabhethri esimanje, ikakhulukazi izinhlobo ze-lithium-ion, afakwe i-BMS.
Iqhaza: I-BMS ivikela ibhethri ekushajweni ngokweqile, ekukhishweni ngokweqile, kwi-overcurrent, namazinga okushisa adlulele.
Umthelela Kumandla: Okubi kakhulu, i-BMS ngokuvamile izoba nomkhawulo wamanje omkhulu wokukhipha oqhubekayo kanye nomkhawulo wamanje wokukhishwa okuphezulu. Noma ngabe amaseli ebhethri angahlinzeka ngokwamanje okwengeziwe ngokususelwe ku-C-rate yawo, i-BMS izovala okukhiphayo ukuze ivimbele umonakalo.
