AC vs DC Charging: Qhov txawv yog dab tsi?

Hluav taws xob yog lub caj qaum ntawm txhua lub tsheb hluav taws xob. Txawm li cas los xij, tsis yog txhua qhov hluav taws xob zoo ib yam. Muaj ob hom hluav taws xob tam sim no: AC (alternating tam sim no) thiab DC (direct tam sim no). Hauv tsab ntawv tshaj tawm no, peb yuav tshawb xyuas qhov sib txawv ntawm AC thiab DC them nyiaj thiab lawv cuam tshuam li cas cov txheej txheem them hluav taws xob. Tab sis ua ntej peb delve rau hauv cov ntsiab lus, cia peb qhia ib yam dab tsi ua ntej. Hloov tam sim no yog dab tsi los ntawm daim phiaj hluav taws xob (piv txwv li, koj lub qhov hluav taws xob hauv tsev). Direct tam sim no yog lub zog khaws cia hauv koj lub tsheb fais fab roj teeb

EV charging: qhov sib txawv ntawm AC thiab DC

 DC zog

 DC (direct tam sim no) lub zog yog ib hom hluav taws xob hluav taws xob uas ntws hauv ib qho kev taw qhia. Tsis zoo li AC lub zog, uas hloov cov kev taw qhia ib ntus, DC lub zog ntws mus tas li. Nws feem ntau siv rau hauv cov khoom siv uas yuav tsum tau muaj lub zog tsis tu ncua, xws li khoos phis tawj, TV, thiab smartphones. DC lub zog yog tsim los ntawm cov khoom siv xws li EV roj teeb thiab cov hnub ci vaj huam sib luag, uas tsim cov hluav taws xob tsis tu ncua. Tsis zoo li AC lub zog, uas tuaj yeem hloov pauv tau yooj yim mus rau qhov sib txawv ntawm cov khoom siv hluav taws xob, DC lub zog yuav tsum muaj cov txheej txheem hloov dua siab tshiab los hloov nws qhov hluav taws xob.

AC zog

AC (alternating tam sim no) fais fab yog ib hom hluav taws xob fais fab uas hloov cov kev taw qhia txhua lub sijhawm tam sim no thiab tom qab ntawd. Kev taw qhia ntawm AC voltage thiab tam sim no hloov pauv ib ntus, feem ntau ntawm 50 lossis 60 Hz. Cov kev taw qhia ntawm cov hluav taws xob tam sim no thiab qhov hluav taws xob thim rov qab ntawm qhov tsis tu ncua, uas yog vim li cas nws thiaj li hu ua alternating tam sim no. Cov hluav taws xob AC ntws los ntawm cov kab hluav taws xob thiab mus rau hauv koj lub tsev, qhov twg nws nkag tau los ntawm cov hluav taws xob hluav taws xob.

AC thiab DC charging pros thiab cons

 AC charging pros:

1. Kev siv tau. AC charging yog siv tau rau cov neeg feem coob vim tias nws tuaj yeem ua tiav siv lub qhov hluav taws xob txheem. Qhov no txhais tau hais tias cov neeg tsav tsheb EV tuaj yeem them nyiaj hauv tsev, ua haujlwm, lossis cov chaw pej xeem yam tsis muaj cov cuab yeej tshwj xeeb lossis kev tsim kho.
2. Kev nyab xeeb. Kev them nyiaj AC feem ntau suav tias muaj kev nyab xeeb dua li lwm txoj hauv kev them nyiaj vim nws xa lub zog hauv sine waveform, uas tsis tshua muaj kev cuam tshuam hluav taws xob ntau dua li lwm cov waveforms.

1. Muaj peev xwm. AC them nqi tsawg dua li lwm txoj kev them nqi vim nws tsis xav tau cov cuab yeej tshwj xeeb lossis kev tsim kho. Qhov no ua rau nws muaj txiaj ntsig zoo rau ntau tus neeg.

AC charging cons:

1. Lub sij hawm them nqi qeeb.AC chargers muaj peev xwm them nqi tsawg thiab qeeb dua DC chaw nres tsheb, uas tuaj yeem yog qhov tsis zoo rau EVs uas yuav tsum tau them ceev ceev ntawm txoj kev, xws li cov siv rau kev mus los ntev. Lub sij hawm them rau AC them tuaj yeem nyob ntawm ob peb teev mus txog rau hnub, nyob ntawm lub roj teeb lub peev xwm.

1. Zog efficiency.AC chargers tsis muaj zog npaum li cov chaw them nyiaj ceev ceev vim tias lawv xav tau lub tshuab hloov pauv los hloov qhov hluav taws xob. Cov txheej txheem hloov dua siab tshiab no ua rau qee lub zog poob, uas tuaj yeem ua rau tsis zoo rau cov neeg uas txhawj xeeb txog kev siv hluav taws xob

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

Qhov no yuav nyob ntawm koj qhov kev xav tau them nqi. Yog tias koj tsav tsheb luv luv nyob rau ib hnub, ces kev siv lub AC charger yuav tsum txaus. Tab sis yog tias koj ib txwm nyob ntawm txoj kev thiab tsav tsheb mus deb, DC them nyiaj yog qhov kev xaiv zoo dua, vim tias koj tuaj yeem them koj cov EV hauv tsawg dua ib teev. Nco ntsoov tias kev them nyiaj sai sai tuaj yeem ua rau lub roj teeb degradation vim lub zog siab ua rau kub ntau dhau.

Puas yog EVs khiav ntawm AC lossis DC?

Cov tsheb hluav taws xob khiav ntawm qhov hluav taws xob ncaj qha. Lub roj teeb hauv EV khaws cov hluav taws xob hluav taws xob hauv DC hom, thiab lub zog hluav taws xob uas ua rau lub tsheb khiav ntawm DC lub zog ib yam. Rau koj cov kev xav tau them EV, mus saib Lectron cov khoom ntawm EV chargers, adapters, thiab ntau dua rau Tesla thiab J1772 EVs.
