1. Uyini ugesi wangaphandle futhi uyini umehluko phakathi kwawo nebhange lamandla?
Amandla angaphandle, empeleni abizwa ngokuthi amandla eselula angaphandle, alingana nesiteshi sokushaja esiphathwayo.Isici esiyinhloko ukucushwa kwezinhlobo ezahlukene zezimbobo zokuphuma:
I-USB, i-TypeC, ingashaja amadivaysi edijithali ajwayelekile.
Isixhumi esibonakalayo sokushaja imoto, singashaja ibhethri lemoto, noma amanye amandla ezinto ezisebhodini.
Sekela okukhiphayo okungu-220V AC, okulingana nokusetshenziswa kwamandla amapayipi ekhaya.
Uyini umehluko phakathi kwayo ne-power bank?
1. Amandla okukhipha
Njengamanje, ibhange lokushaja umakhalekhukhwini emakethe, amandla okukhiphayo acishe abe ngu-22.5W.Ibhange lamandla lekhompuyutha ephathekayo, 45-50W.
Ukunikezwa kwamandla kwangaphandle kuqala ku-200W, izinhlobo eziningi zemikhiqizo zingaphezu kuka-500W, futhi umkhawulo ungaba ngaphezu kuka-2000W.
Amandla aphezulu asho ukuthi ungasebenzisa izinto zikagesi ezinamandla.
2. Amandla
Ngaphambi kokuthi ngiqhathanise umthamo, kufanele ngikutshele ngamayunithi.
Iyunithi yebhange lamandla i-mAh (mah), ngokuvamile ebizwa ngokuthi mah ngamafuphi.
Iyunithi yokuphakelwa kwamandla kwangaphandle i-Wh (watt-hora).
Kungani kunomehluko?
1. Ngenxa yokuthi i-voltage ephumayo yebhange lokushaja incane kakhulu, i-voltage ephumayo yebhange lokushaja iselula ingu-3.6V, efana ne-voltage yokusebenza yeselula.
Futhi ngenxa yenkinga ye-voltage, uma ufuna ukusebenzisa ibhange lamandla ukushaja i-laptop yakho (i-voltage yokusebenza 19V), kufanele uthenge i-laptop ekhethekile.
2 Wh, le yunithi, empeleni isho ukusetshenziswa kwamandla noma umthamo, okungenzeka awukawuboni.Kodwa ake ngisho lokhu, futhi uzowuthola umqondo wakho:
1000Wh = 1kWh = 1 KWH.
Ifomula yokuguqula yala mayunithi amabili: W (umsebenzi, iyunithi Wh) = U (voltage, iyunithi V) * Q (ishaji, iyunithi Ah)
Ngakho-ke, ibhange lokushaja iselula engu-20000mAh, umthamo walo ngu-3.6V * 20Ah = 72Wh.
Umthamo ojwayelekile wokuphakelwa kwamandla wangaphandle okungenani ungu-300Wh.Leso yigebe lamandla.
Isibonelo: (kungakhathaliseki ukulahlekelwa)
I-voltage yokusebenza yebhethri yeselula ingu-3.6V, ukushaja kungu-4000mAh, bese kuba namandla ebhethri leselula =3.6V * 4Ah = 14.4Wh.
Uma ibhange lokushaja elingu-20000mAh, ukushaja le foni yeselula, lingashaja 72/14.4 ≈ izikhathi ezingu-5.
Ukunikezwa kwamandla kwangaphandle kwe-300Wh kungashajwa 300/14.4 ≈ izikhathi ezingu-20.
2. Yini engenziwa ugesi wangaphandle?
Uma udinga ugesi ngaphandle, izinto zikagesi zangaphandle zingakusiza.Ngokwesibonelo,
1. Misa indawo yokudayisa yangaphandle futhi unikeze amandla amalambu okukhanyisa.
I-2, ukukhempa kwangaphandle kanye nohambo lokuzishayela, kunezindawo eziningi zokusebenzisa ugesi, ufuna ukudinga ugesi, amandla angaphandle angakwenza.
Sebenzisa iprojektha
Shisisa amanzi ashisayo bese upheka nge-rice cooker
Ezindaweni lapho amalangabi avulekile angase angavunyelwe, umthombo wamandla ongaphandle uzokuvumela ukuthi usebenzise umpheki wakho werayisi ngokuphepha.
Ukushaja idivayisi yedijithali (i-UAV, iselula, ikhompuyutha)
Sebenzisa isiqandisi semoto
3, uma kuyi-RV, isikhathi eside ngaphandle, amandla angaphandle angaba yinto edingekayo.
I-4, ihhovisi leselula, lapho ingekho indawo yokushaja, ungaqinisekisa ukuthi ikhompuyutha noma umakhalekhukhwini, ukukhathazeka okuhlukile ngenkinga kagesi isikhathi eside, impilo yebhethri inamandla kakhulu kunebhange lamandla.
I-5, kubangane bokudoba ensimini, ukunikezwa kwamandla kwangaphandle kungashaja ukukhanya kokudoba ensimini, noma ngokuqondile njengesibani sokudoba ongasisebenzisa.
6. Ebangani abathwebula izithombe, ugesi wangaphandle uyindawo ewusizo kakhulu:
Esikhundleni sokuthwala amabhethri amaningi, ukunika amandla amalambu ekhamera.
Noma njengezibani ze-LED, gcwalisa ukusetshenziswa kokukhanya.
I-7, ukusebenza kwangaphandle, kwemishini yamandla aphezulu, amandla angaphandle nawo ayadingeka.
8. Indawo yokulondoloza izimo eziphuthumayo.
Akudingekile ukuba ube ngaphandle ukuze usebenzise amandla angaphandle.Uma ugesi uphela ekhaya, ugesi wangaphandle ungasetshenziswa njengesibani esiphuthumayo.
Isibonelo, izinhlekelele zemvelo ezihlukahlukene zalo nyaka, ukuphuma kwamandla okuhlala akufiki isikhathi eside, ukubaluleka kokunikezwa kwamandla angaphandle kubonakala.Amanzi ashisayo, ukushaja umakhalekhukhwini, njll.
3, khetha ukunikezwa kwamandla kwangaphandle, yisiphi isidingo sokunaka?(Amaphuzu abalulekile)
1. Iyini ukusetshenziswa kwamanzi?
Yonke imishini kagesi, kukhona ukusetshenziswa kwamandla.Uma amandla ebhethri engekho kuwo, awukwazi ukukuthwala.
2. Umehluko phakathi kwe-mAh ne-Wh.
Nakuba sekumbozwe kancane ngenhla, leli yiphuzu elidukisa kakhulu, ngakho-ke ake ngikucacise.
Ngamafuphi: awukwazi ukusho ukuthi umthamo wangempela uyini uma ubheka nje i-mAh, ngoba amandla okusebenza ahlukile.
I-mAh (milliampere) iyunithi kagesi emelela inani lokushajwa Q ibhethri elingakwazi ukuyibamba noma ukuyikhulula.
Okuvamile ukuthi: sikhuluma ngomthamo webhethri leselula noma ibhange lamandla, mangaki ama-milliamp.
I-Wh iyunithi yokusetshenziswa kwamandla, emele umsebenzi ongenziwa ibhethri.
I-Wh ibizwa ngokuthi i-watt-hora, kanye nehora le-kilowatt elingu-1 (kWh) = ihora le-kilowatt elingu-1 likagesi.
Ukuguqulwa phakathi kwe-Wh ne-mAh: Wh*1000/ voltage = mAh.
Ngakho-ke iningi lebhizinisi lamandla langaphandle limaka mAh, liguqulwa amandla kagesi weselula engu-3.6V, abonise umthamo omkhulu.
Isibonelo, i-600Wh ingaguqulelwa ku-600 * 1000/3.6 = 166666mAh.
Ukufingqa kancane:
I-1, amandla amancane okunikezwa kwamandla angaphandle (300W ngezansi), okuningi ukubona i-mAh, ngoba ukunakekelwa okwengeziwe kuwukuthi: zingaki izisetshenziswa zikagesi ezingashajwa.
2, amandla amakhulu ngokuqhathaniswa amandla angaphandle (ngaphezu kuka-500W), ngaphezulu ukuze ubone i-Wh, ngoba ungakwazi ukubala kangcono isikhathi sokuphakelwa kwamandla kagesi wamandla aphezulu.
Isibonelo, i-500W rice cooker +600Wh umthamo wamandla wangaphandle, ingabala ngokuqondile isikhathi esisebenzisekayo: 600/500 = amahora angu-1.2.Uma iku-mAh, kuba nzima ukuyiqonda.
Uma ungakaqiniseki, swayipha uye ekupheleni kwesihloko, lapho ngifingqe khona ezinye izisetshenziswa zikagesi, nokuthi zishajwe kangaki noma zinikwe amandla isikhathi eside kangakanani.
3. Imodi yokushaja
Ama-main (ashaja ekhaya)
Imali yokushayela
Ukushaja iphaneli yelanga (Ngaphandle)
Uma uchitha isikhathi esiningi ungaphandle, noma ku-RV, amaphaneli elanga ayadingeka.
Lapho uthenga ugesi wangaphandle, izinhlobo ezahlukene zemikhiqizo zinenhlanganisela: amandla angaphandle kanye namaphaneli elanga (izintengo zizokwenyuka).
4. Ukuqina
Izinsiza zamandla zangaphandle ezi-2 ngokuhambisana, khulisa amandla obukhulu.
Umthombo wamandla owodwa wangaphandle +1~2 amaphakethe wokushaja.
Iphakethe lamandla lingasetshenziswa kuphela njengebhethri, ngokuhambisana namandla angaphandle, anomsebenzi omncane kakhulu.
5. Umphumela we-waveform
I-sine wave emsulwa kuphela, ngeke ilimaze izinto zikagesi, ikakhulukazi okokusebenza kwedijithali, ngakho-ke kufanele unake ukuthengwa.
Lawa engiwabale ngezansi amagagasi e-sine amsulwa, ngaphandle kuka-Habilis.
5. Isincomo semodeli
Ngaphansi kuka-1,300 W
2,600 W
3,1000 W kuya ku-1400W
4,1500 W-2000W (izoqhubeka)
Nazi izinto ezimbalwa okufanele uziqaphele:
Ukunikezwa kwamandla kwangaphandle ngaphansi kuka-1,300 W kunezimo zohlelo ezilinganiselwe ngenxa yamandla ako aphansi
Ukukhanyisa okuphuthumayo
Isitolo sangaphandle
Ukushaja idivayisi yedijithali
Ngoba ukunakekelwa okwengeziwe mayelana nomthamo, ngakho-ke isibalo esilandelayo sokuqhathanisa, umthamo awunawo Wh, futhi usebenzise i-mAh ukuze ubonise ngokucacile.
Ngokunikezwa kwamandla angaphandle angaphezu kuka-2,600 W, indlela yezinga engiyincomayo imi kanje:
Ngohlelo olukhuphukayo lwamandla aphezulu kanye nomthamo webhethri
Bese ngokwenyuka ngokulandelana kwentengo.
Kungani ungacabangi ngentengo kuqala?
Isizathu silula.Udinga ukwenza isiqiniseko sokuthi unamandla amakhulu nomthamo ngaphambi kokuthi ucabangele intengo.
Futhi ukuklama jikelele ugesi ongaphandle, umthamo futhi anda ngamandla.
3. Amanye amapharamitha:
Amandla aphezulu.Ezinye izinto ezisetshenziswayo, njengamaphampu omoya noma izibani ezikhanyayo, zinamandla asheshayo, okusho amandla amaningi okwesikhashana.
