Thaum muaj kev tshawb fawb qhia tau hais tias nquag ceev (DC) them tuaj yeem ua rau lub roj teeb qis duaAC them nyiaj, cov nyhuv ntawm roj teeb heath yog me ntsis. Qhov tseeb, DC them tsuas yog nce roj teeb tsis zoo li ntawm 0.1 feem pua ntawm qhov nruab nrab.
Kev kho koj lub roj teeb kom zoo muaj ntau yam kev tswj xyuas qhov kub thiab txias dua li lwm yam, vim lithium-ion (Li-ion) roj teeb muaj qhov kub thiab txias. Hmoov zoo, feem ntau niaj hnubEVsmuaj built-in kub tswj systems los tiv thaiv lub roj teeb, txawm tias thaum them ceev.
Ib qho kev txhawj xeeb feem ntau yog nyob ib ncig ntawm qhov cuam tshuam ntawm kev them nyiaj ceev ntawm lub roj teeb degradation - qhov kev txhawj xeeb nkag siab tau muab rau qhov ntawdEV Chargerscov tuam txhab xws li Kia thiab txawm tias Tesla pom zoo kom siv cov kev them nyiaj ceev ceev hauv cov lus piav qhia ntxaws ntxaws ntawm qee yam ntawm lawv cov qauv.
Yog li dab tsi yog qhov cuam tshuam ntawm kev them nyiaj ceev ntawm koj lub roj teeb, thiab nws puas yuav cuam tshuam rau koj lub roj teeb kev noj qab haus huv? Hauv tsab xov xwm no, peb yuav rhuav tshem qhov kev them nyiaj sai npaum li cas thiab piav qhia seb nws puas muaj kev nyab xeeb rau koj siv EV.
Dab tsi yogthem ceev ceev?
Ua ntej peb sim teb seb puas them ceev ceev yog qhov zoo rau koj EV, peb yuav tsum xub piav qhia seb qhov them nyiaj ceev yog dab tsi hauv thawj qhov chaw. Kev them nyiaj ceev, tseem hu ua Theem 3 lossis DC them, yog hais txog cov chaw them nqi ceev tshaj plaws uas tuaj yeem them koj EV hauv feeb tsis yog teev.
Fais fab tso zis sib txawv ntawmchaw them nqi, tab sis DC ceev chargers tuaj yeem xa tawm ntawm 7 mus rau 50 npaug ntawm lub zog ntau dua li qhov chaw them nyiaj AC li niaj zaus. Thaum lub hwj chim siab no yog qhov zoo rau kev nce qib ntawm EV, nws kuj ua rau muaj cua sov ntau thiab tuaj yeem tso lub roj teeb hauv kev ntxhov siab.
Qhov cuam tshuam ntawm kev them ceev ceev ntawm lub tsheb fais fab roj teeb
Yog li, dab tsi yog qhov tseeb ntawm kev them nyiaj ceev ntawm qhov cuam tshuam rauEV roj teebnoj qab haus huv?
Qee qhov kev tshawb fawb, xws li Geotabs 'kev tshawb fawb los ntawm 2020, pom tias dhau ob xyoos, kev them nyiaj ceev ntau dua peb zaug hauv ib hlis nce roj teeb degradation los ntawm 0.1 feem pua piv rau cov neeg tsav tsheb uas tsis tau siv ceev ceev.
Lwm txoj kev tshawb fawb los ntawm Idaho National Laboratory (INL) tau sim ob khub ntawm Nissan Leafs, them lawv ob zaug ib hnub hauv ib xyoos, nrog ib khub tsuas yog siv AC them nyiaj li niaj zaus thaum lwm tus tsuas yog siv DC them ceev xwb.
Tom qab yuav luag 85,000 mais ntawm txoj kev, cov khub uas tsuas yog them tus nqi them sai sai poob 27 feem pua ntawm lawv lub peev xwm qub, thaum khub uas siv AC them nyiaj poob 23 feem pua ntawm lawv cov roj teeb thawj zaug.
Raws li ob qho kev tshawb fawb qhia, kev them nyiaj ceev tsis tu ncua txo cov roj teeb kev noj qab haus huv ntau dua li AC them, txawm hais tias nws qhov cuam tshuam tseem me me, tshwj xeeb tshaj yog thaum xav txog lub neej tiag tiag tsis xav tau ntawm lub roj teeb dua li cov kev ntsuas no.
Yog li, koj puas yuav tsum them sai sai rau koj EV?
Theem 3 them yog ib qho kev daws teeb meem yooj yim rau kev them nyiaj sai sai ntawm kev mus, tab sis hauv kev xyaum, koj yuav pom tias qhov kev them nyiaj AC niaj hnub ua tau raws li koj cov kev xav tau niaj hnub no.
Qhov tseeb, txawm tias qhov qeeb tshaj plaws ntawm qib 2 them, qhov nruab nrab EV tseem yuav them tag nrho hauv qis dua 8 teev, yog li kev siv ceev ceev tsis zoo li qhov kev paub niaj hnub rau cov neeg feem coob.
Vim hais tias DC ceev chargers muaj ntau bulkier, kim rau nruab, thiab yuav tsum tau ib tug ntau dua voltage rau kev khiav hauj lwm, lawv tsuas muaj peev xwm nrhiav tau nyob rau hauv tej qhov chaw, thiab zoo li yuav siv tau ntau npaum li cas kim tshaj.AC cov chaw them nqi pej xeem.
Kev nce qib hauv kev them nyiaj ceev
Nyob rau hauv ib qho ntawm peb REVOLUTION Live podcast ntu, FastNed's Head of Charging Technology, Roland van der Put, tau hais tias cov roj teeb niaj hnub no feem ntau yog tsim los kom them sai sai thiab muaj kev sib xyaw ua ke txias kom tswj tau lub zog siab dua los ntawm kev them nyiaj ceev.
Qhov no yog qhov tseem ceeb tsis yog rau kev them nyiaj ceev nkaus xwb tab sis kuj rau huab cua huab cua, vim tias koj lub roj teeb EV yuav raug kev txom nyem los ntawm qhov txias heev lossis sov heev. Qhov tseeb, koj lub roj teeb EVs ua haujlwm zoo hauv qhov nqaim ntawm qhov kub ntawm 25 thiab 45 ° C. Cov kab ke no tso cai rau koj lub tsheb kom ua haujlwm thiab them nyiaj hauv qhov kub qis lossis siab tab sis tuaj yeem txuas ntxiv lub sijhawm them nyiaj yog tias qhov ntsuas kub tsis zoo sab nraud.
