Yuav siv sijhawm ntev npaum li cas los them tus nqi EV nrog lub Charger Portable?
Feem ntau hais lus, lub hwj chim tso zis ntawm portable EV chargers (xws liPortable Type 2 EV chargers) yog qhov tsawg, nrog cov kev qhia tshwj xeeb xws li 1.5 kW txog 3 kW. Lub sij hawm them nqi txawv txawv nyob ntawm lub tsheb lub roj teeb muaj peev xwm.
Piv txwv li, ib lub tsheb hluav taws xob hauv tsev ib txwm muaj lub peev xwm ntawm 50 kWh yuav siv sijhawm kwv yees li ntawm50 ÷ 1.5 ≈ 33.3 teevkom them tag nrho siv 1.5 kW thaum muaj xwm ceev hluav taws xob tsheb charger. Yog tias siv 3 kW portable Type 2 EV charger, lub sijhawm them yuav raug txo kom txog50 ÷ 3 ≈ 16.7 teev.
Txawm li cas los xij, lub sijhawm them nyiaj tiag tiag cuam tshuam los ntawm lub zog poob thaum lub sijhawm ua haujlwm, yog li nws feem ntau yog me ntsis ntev dua li qhov kev xam pom. Tsis tas li ntawd, cov neeg nyob hauv siab - cov tsev nce siab tuaj yeem ntsib cov kev txwv cuam tshuam nrog lub zog muaj peev xwm hauv zej zog. Yog tias muaj ntau tus neeg nyob ze siv siab - cov khoom siv hluav taws xob tib lub sijhawm, lub zog them nqi tiag tiag yuav txo qis, txuas ntxiv lub sijhawm them nyiaj ntxiv.
Hauv qab no yog cov ntsiab lus tseem ceeb uas txiav txim siab EV them lub sijhawm thaum siv lub charger portable:
1. Charger Fais fab
Portable EV chargers muaj nyob rau hauv ntau qhov sib txawv zog, nrog rau 1.5 kW thiab 3 kW yog qhov feem ntau. Cov zis hluav taws xob ntau dua ncaj qha txhais mus rau hauv kev them nyiaj sai dua rau tib lub roj teeb muaj peev xwm.
Piv txwv li, aHom 2 portable EV chargermuaj dav dav hauv cov fais fab no kom tau raws li kev them nyiaj txhua hnub thiab kev xav tau xwm txheej ceev. Rau ib lub tsheb nrog 60 kWh roj teeb, 1.5 kW thaum muaj xwm ceev hluav taws xob tsheb charger yuav siv sij hawm kwv yees.60 ÷ 1.5=40 teevkom them tag nrho, thaum lub 3 kW portable Type 2 EV charger tuaj yeem txo lub sijhawm mus txog20 teev.
Rau cov neeg siv nrhiav kev them nyiaj sai dua yam tsis muaj kev cia siab rau pej xeem DC ceev chargers, 7 kW portable EV charger tuaj yeem yog qhov ua tau zoo. Hais tias, nws yog ib qho tseem ceeb kom paub meej tias kev sib raug zoo nrog ob lub tsheb thiab cov khoom siv hluav taws xob hauv tsev lossis hauv zej zog.
2. Lub tsheb roj teeb muaj peev xwm
Roj teeb muaj peev xwm sib txawv ntawm cov tsheb fais fab, xws li los ntawm ntau kaum ntawm kilowatt-teev mus rau ntau tshaj ib puas kilowatt- teev. Qhov no yog ib qho tseem ceeb tshaj plaws cuam tshuam rau lub sijhawm them nyiaj.
Piv txwv li, ib lub tsheb nrog 40 kWh roj teeb yuav siv li ntawm40 ÷ 1.5 ≈ 26.7 teevkom them tag nrho siv 1.5 kW Hom 2 portable EV charger. Nyob rau hauv sib piv, ib tug 80 kWh roj teeb them nrog tib 1.5 kW thaum muaj xwm ceev hluav taws xob tsheb charger yuav xav tau kwv yees li ntawm80 ÷ 1.5 ≈ 53.3 teev.
Txawm tias siv lub zog ntau dua7 kW portable EV charger, lub roj teeb 80 kWh tseem yuav siv sij hawm ib ncig80 ÷ 7 ≈ 11.4 teev(tom qab suav txog kev poob zog). Txawm hais tias qhov no yog qhov nrawm dua li qis dua - txoj kev xaiv fais fab, nws tseem xav tau kev npaj rau hmo ntuj lossis ncua sijhawm them nyiaj ntxiv.
3. Kev them nqi hluav taws xob poob
Thaum lub sij hawm them tus txheej txheem, ib feem ntawm lub zog yog inevitably poob raws li cua sov los yog vim hluav taws xob tsis kam. Yog li ntawd, lub sij hawm them nqi tiag tiag yog ib txwm ntev dua li qhov kev xam pom. Lub zog poob feem ntau yog los ntawm5% mus rau 10%, nyob ntawm tej yam xws li kev sib raug zoo ntawm lub charger (piv txwv li, portable Type 2 EV charger) thiab lub tsheb, nrog rau tej yam kev mob xws li ambient kub.
Piv txwv li, them lub roj teeb 50 kWh nrog 3 kWHom 2 portable EV chargermuaj lub sijhawm them theoretical ntawm 16.7 teev, tab sis hauv kev xyaum, nws yuav siv sijhawm kwv yees li17.5-18.4 dr habvim poob zog. High- cov khoom siv hluav taws xob zoo, xws li Nanjing JUSWIN's 7 kW portable EV charger, yog tsim los txo cov kev poob no los ntawm kev tsim hluav taws xob zoo, pab xa cov kev them nyiaj ruaj khov thiab zoo ib yam.
4. Cov Kev Pabcuam Hauv Zej Zog
Cov neeg nyob hauv siab -cov tsev nce siab lossis cov zej zog laus feem ntau ntsib cov kev txwv cuam tshuam txog kev muaj peev xwm muab hluav taws xob. Yog tias ntau tsev neeg ua haujlwm siab -cov khoom siv hluav taws xob- xws li lub tshuab cua txias lossis lub tshuab hluav taws xob cua sov-los yog siv lwm cov khoom siv hluav taws xob EV nyob rau tib lub sijhawm, daim phiaj hluav taws xob yuav poob. Qhov no tuaj yeem ua rau lub zog tso zis tiag tiag ntawm aPortable Type 2 EV chargerlos yog thaum muaj xwm ceev hluav taws xob tsheb charger kom txo.
Piv txwv li, 3 kW charger tuaj yeem ua haujlwm tsuas yog 2.5 kW nyob rau hauv lub zog tsis ruaj khov, nce lub sijhawm them rau 50 kWh roj teeb los ntawm 16.7 teev mus rau ib puag ncig.20 teev. Yog li ntawd nws yog qhov tsim nyog los ntsuas lub zog hauv zej zog ua ntej xaiv qhov siab dua - lub zog xaiv zoo li 7 kW portable EV charger. Xwb, xaiv cov chargers nruab nrog ua - nyob rau hauv voltage stabilization nta tuaj yeem pab hloov tau cov khoom siv hluav taws xob sib txawv.
Cov ntsiab lus
Portable EV chargers muab kev yooj yim thiab yooj yim, tab sis lub sij hawm them nyiaj nyob ntawm ntau yam, suav nrog lub hwj chim charger, roj teeb muaj peev xwm, lub zog poob, thiab lub zog hauv zos. Kev nkag siab txog cov kev hloov pauv no pab EV cov tswv xaiv cov kev daws teeb meem uas siv tau yooj yim thiab npaj cov sij hawm them nqi zoo dua.
