Kev Them Nqi AC vs DC: Qhov Txawv Yog Dab Tsi?

Hluav taws xob yog lub hauv paus ntawm txhua lub tsheb fais fab. Txawm li cas los xij, tsis yog txhua lub hluav taws xob zoo ib yam. Muaj ob hom hluav taws xob tseem ceeb: AC (alternating current) thiab DC (direct current). Hauv tsab blog no, peb yuav tshawb nrhiav qhov sib txawv ntawm AC thiab DC them thiab lawv cuam tshuam li cas rau cov txheej txheem them ntawm cov tsheb fais fab. Tab sis ua ntej peb nkag mus rau hauv cov ntsiab lus, cia peb piav qhia qee yam ua ntej. Alternating current yog qhov los ntawm lub zog fais fab (piv txwv li, koj lub qhov hluav taws xob hauv tsev). Direct current yog lub zog khaws cia rau hauv koj lub roj teeb tsheb fais fab.

Kev them EV: qhov txawv ntawm AC thiab DC

 DC fais fab

 Lub zog DC (direct current) yog ib hom fais fab uas ntws mus rau ib qho kev taw qhia. Tsis zoo li lub zog AC, uas hloov kev taw qhia los ntawm lub sijhawm mus rau lub sijhawm, lub zog DC ntws mus rau hauv kev taw qhia tas li. Nws feem ntau siv rau hauv cov khoom siv uas xav tau lub zog tas li, xws li cov khoos phis tawj, TV, thiab smartphones. Lub zog DC yog tsim los ntawm cov khoom siv xws li EV roj teeb thiab cov vaj huam sib luag hnub ci, uas tsim cov hluav taws xob tas li. Tsis zoo li lub zog AC, uas tuaj yeem hloov pauv mus rau ntau qhov voltages siv transformers, lub zog DC xav tau cov txheej txheem hloov pauv nyuaj dua los hloov nws lub voltage.

AC fais fab

Lub zog AC (alternating current) yog ib hom fais fab uas hloov kev taw qhia txhua lub sijhawm. Kev taw qhia ntawm AC voltage thiab tam sim no hloov pauv tas li, feem ntau ntawm 50 lossis 60 Hz. Kev taw qhia ntawm tam sim no thiab voltage rov qab tas li, yog vim li cas nws thiaj hu ua alternating current. Lub zog AC ntws los ntawm cov xov hluav taws xob thiab mus rau hauv koj lub tsev, qhov chaw uas nws nkag tau los ntawm cov qhov hluav taws xob.

Cov txiaj ntsig thiab qhov tsis zoo ntawm AC thiab DC them hluav taws xob

 Cov yam ntxwv ntawm AC charging:

1. Kev Nkag Tau Yooj Yim. Kev them hluav taws xob AC yog qhov yooj yim rau cov neeg feem coob vim tias nws tuaj yeem ua tiav los ntawm kev siv lub qhov hluav taws xob ib txwm muaj. Qhov no txhais tau tias cov neeg tsav tsheb EV tuaj yeem them hluav taws xob hauv tsev, chaw ua haujlwm, lossis cov chaw pej xeem yam tsis muaj cov khoom siv tshwj xeeb lossis cov khoom siv hauv paus.
2. Kev Nyab Xeeb. Feem ntau, kev them hluav taws xob AC raug suav hais tias muaj kev nyab xeeb dua li lwm txoj kev them hluav taws xob vim nws xa hluav taws xob hauv lub sine waveform, uas tsis tshua muaj feem ua rau muaj hluav taws xob poob siab dua li lwm cov waveforms.

1. Kev them nqi pheej yig. Kev them hluav taws xob AC pheej yig dua li lwm txoj kev them vim nws tsis xav tau cov khoom siv tshwj xeeb lossis cov khoom siv hauv paus. Qhov no ua rau nws yog qhov kev xaiv pheej yig dua rau cov neeg feem coob.

Cov teeb meem ntawm AC charging:

1. Lub sijhawm them qeeb.Cov chaw them hluav taws xob AC muaj lub zog them tsawg thiab qeeb dua li cov chaw nres tsheb DC, uas tuaj yeem ua rau tsis zoo rau cov tsheb EV uas xav tau kev them hluav taws xob sai ntawm txoj kev, xws li cov uas siv rau kev mus ncig deb. Lub sijhawm them rau kev them hluav taws xob AC tuaj yeem ntev li ob peb teev mus txog rau hnub, nyob ntawm lub peev xwm ntawm lub roj teeb.

1. Kev siv hluav taws xob zoo.Cov chaw them hluav taws xob AC tsis txuag hluav taws xob zoo li cov chaw them hluav taws xob ceev heev vim tias lawv xav tau lub transformer los hloov qhov hluav taws xob. Cov txheej txheem hloov pauv no ua rau muaj qee qhov poob hluav taws xob, uas tuaj yeem ua rau muaj qhov tsis zoo rau cov neeg uas txhawj xeeb txog kev txuag hluav taws xob.

Puas yog AC lossis DC zoo dua rau kev them nyiaj?

Qhov no yuav nyob ntawm seb koj xav tau kev them fais li cas. Yog tias koj tsav tsheb luv luv txhua hnub, ces siv lub AC charger los them fais tas li yuav txaus. Tab sis yog tias koj ib txwm nyob ntawm txoj kev thiab tsav tsheb ntev, DC charging yog qhov kev xaiv zoo dua, vim tias koj tuaj yeem them koj lub EV tag nrho hauv tsawg dua ib teev. Nco ntsoov tias kev them fais sai sai ntau zaus tuaj yeem ua rau lub roj teeb puas tsuaj vim tias lub zog siab ua rau muaj cua sov ntau dhau.

Cov tsheb fais fab (EVs) puas khiav ntawm AC lossis DC?

Cov tsheb fais fab khiav ntawm hluav taws xob ncaj qha. Lub roj teeb hauv EV khaws lub zog hluav taws xob hauv hom DC, thiab lub cev muaj zog hluav taws xob uas muab lub zog rau lub tsheb kuj khiav ntawm lub zog DC thiab. Rau koj cov kev xav tau them EV, mus saib Lectron cov khoom siv them EV, cov khoom siv hloov kho, thiab ntau ntxiv rau Tesla thiab J1772 EVs.
