Dab tsi yog qhov txawv ntawm AC thiab DC them? | iFlowPower

Hluav taws xob tsheb them thev naus laus zis suav nrog ob daim ntawv tseem ceeb:  Hloov tam sim no (AC)  Thiab lub tswv  direct tam sim no (DC) .

Nyob rau hauv lub realm ntawm hluav taws xob tsheb (EV) them, ob leeg AC (alternating tam sim no) Thiab lub tswv DC (direct tam sim no) txoj kev them nyiaj ua si lub luag haujlwm tseem ceeb, txhua qhov muab qhov zoo sib xws thiab ua kom muaj ntau yam kev xav tau them nqi. Cia peb nkag siab tob rau qhov sib txawv ntawm ob txoj kev them nyiaj no, lawv cov hauv paus ntsiab lus, thiab kev siv cov xwm txheej.

AC Charging:

● Lub hauv paus ntsiab lus: AC kev them nyiaj suav nrog kev hloov pauv tam sim no los ntawm daim phiaj hluav taws xob mus rau qhov ncaj qha tam sim no uas xav tau los ntxiv cov roj teeb ntawm lub tshuab them nyiaj. Qhov kev hloov pauv no tshwm sim hauv lub tsheb los ntawm lub charger onboard.

● Muaj: AC charging ports feem ntau pom muaj nyob hauv EVs, tso cai rau kev them nyiaj yooj yim hauv tsev lossis hauv cov chaw uas muaj AC charging infrastructure.

● Kev Siv Scenario: Kev them nyiaj AC yog qhov zoo dua rau cov kev xav tau them txhua hnub, xws li them thaum hmo ntuj hauv tsev lossis lub sijhawm ncua sijhawm so. Txawm hais tias nws qhov kev them nqi qeeb qeeb, AC charging yog tus nqi zoo thiab yooj yim rau kev siv txhua hnub.

DC Charging:

● Lub hauv paus ntsiab lus: DC charging bypasses qhov xav tau ntawm onboard hloov dua siab tshiab los ntawm kev muab cov high-voltage direct tam sim no rau lub tsheb lub roj teeb. Kev hloov pauv ntawm AC rau DC tshwm sim sab nraud hauv qhov chaw them nyiaj.

● Muaj: DC charging ports kuj muaj nyob rau hauv EVs, feem ntau yog siv los them sai sai ntawm cov chaw them nqi rau pej xeem raws txoj kev loj thiab txoj kev loj.

● Kev Siv Scenario: DC charging yog txaus siab rau cov neeg siv uas xav tau cov kev daws teeb meem them sai sai thaum txav mus los lossis rau cov tswv lag luam them nyiaj nrhiav kev pab them nqi zoo. Txawm hais tias tus nqi nce siab dua, qhov ua tau zoo thiab muaj txiaj ntsig ntawm kev them nyiaj sai DC tuaj yeem tshaj qhov pib nqis peev.

Qhov txawv tseem ceeb:

● Kev Them Nqi Them: DC charging muaj qhov nrawm nrawm dua piv rau AC charging, ua rau nws zoo tagnrho rau kev them nyiaj ceev ceev thaum taug kev ntev lossis hauv cov chaw tsheb loj.

● Infrastructure: AC charging relies onboard conversion nyob rau hauv lub tsheb, thaum DC them nrog rau lwm converter khoom nyob rau hauv lub chaw nres tsheb them. Qhov kev sib txawv ntawm cov txheej txheem no cuam tshuam rau kev them nqi thiab kev ceev.

● Kev nyiam siv: Cov neeg siv feem ntau xaiv AC lossis DC them raws li lawv cov kev xav tau tshwj xeeb thiab cov xwm txheej siv. AC charging yog nyiam rau kev them nyiaj niaj hnub hauv tsev, thaum DC charging yog nyiam rau kev them nyiaj sai thaum mus.

Ncob:

Hauv cov ntsiab lus, AC thiab DC charging txoj kev ua kom muaj ntau yam kev xav tau ntawm kev them nyiaj hauv lub tsheb hluav taws xob. Thaum AC them nyiaj yog tsim nyog rau niaj hnub them hauv tsev lossis thaum lub sijhawm so, DC charging muaj cov kev daws teeb meem ceev ceev rau cov neeg siv ntawm kev txav mus los lossis rau cov neeg lag luam uas nrhiav kev pab them nqi zoo. Qhov muaj ntawm ob qho tib si AC thiab DC them cov kev xaiv ua kom yooj yim thiab yooj yim, ua rau muaj kev siv hluav taws xob ntau.
