Tshooj 1: Kev Taw Qhia: Kev Hloov Pauv EV thiab Lub Luag Haujlwm Tseem Ceeb ntawm Kev Them Nqi Hauv Paus

Kev hloov pauv thoob ntiaj teb mus rau kev siv hluav taws xob tsis yog ib qho kev hloov pauv ntxiv lawm; nws yog ib qho kev hloov pauv tseem ceeb hauv kev thauj mus los. Thaum cov teb chaws cog lus rau lub hom phiaj txo cov pa roj carbon dioxide thiab cov tuam txhab tsim tsheb tig lawv cov kab ntau lawm mus rau cov tsheb fais fab roj teeb (BEVs), qhov kev tsom mus rau tau hloov ntawm cov tsheb lawv tus kheej mus rau cov khoom siv uas txhawb nqa lawv. Kev vam meej ntawm qhov kev hloov pauv no nyob ntawm lub network them fais fab uas muaj zog, txhim khu kev qha, thiab npaj tau zoo.

Hauv plawv ntawm kev npaj cov khoom siv no yog qhov kev xaiv tseem ceeb: Kev them AC Qib 2 (L2) piv rau Kev them DC Qib 3 (L3) sai. Txawm hais tias ob qho tib si ua haujlwm tib lub hom phiaj kawg - rov ua kom lub roj teeb ntawm lub tsheb rov qab - lawv sawv cev rau cov txheej txheem thev naus laus zis sib txawv, cov ntaub ntawv peev txheej, thiab kev xav ua haujlwm sib txawv. Rau cov neeg tsim khoom lag luam, cov neeg npaj hauv nroog, thiab cov thawj coj ntawm cov tsheb thauj khoom, kev nkag siab txog qhov sib txawv ntawm ob theem no tsis yog tsuas yog qhov yuav tsum tau ua haujlwm xwb tab sis yog qhov tsim nyog rau kev ua haujlwm.

Kev them nqi theem 2, ua haujlwm ntawm hluav taws xob hloov pauv (AC), tau dhau los ua lub hauv paus ntawm "kev them nqi mus rau qhov chaw." Nws yog qhov kev daws teeb meem uas pom muaj nyob rau hauv tsev, chaw ua haujlwm, tsev so, thiab cov khw muag khoom - qhov chaw uas cov tsheb nres tsheb rau ob peb teev. Qhov sib txawv, Qib 3 DC Kev Them Nqi Ceev (DCFC) yog qhov kev daws teeb meem siab-octane rau "kev them nqi thaum mus ncig." Los ntawm kev hla lub tsheb lub charger thiab xa cov hluav taws xob siab-voltage ncaj qha (DC) ncaj qha mus rau lub roj teeb, DCFC ua rau kev mus ncig deb thiab tig rov qab sai rau cov tsheb thauj khoom lag luam.

Txawm li cas los xij, qhov kev xaiv ntawm L2 thiab L3 tsis tshua muaj binary. Cov tes hauj lwm them hluav taws xob zoo tshaj plaws yog ntau theem, siv qhov kev siv nyiaj ntawm L2 rau cov xwm txheej ntev thiab qhov ceev ntawm L3 rau cov kev xav tau siab.
