Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob (EVSE) yog dab tsi?
Nyob rau hauv lub nthwv dej ntawm kev thauj mus los thoob ntiaj teb hluav taws xob thiab kev hloov hluav taws xob ntsuab, EV cov khoom siv them nyiaj (EVSE, Cov Khoom Siv Tsheb Hluav Taws Xob) tau dhau los ua cov txheej txheem tseem ceeb los txhawb kev thauj mus los zoo, EVSE tsis yog tsuas yog kev them nqi xwb, tab sis ib qho kev sib koom ua ke nrog ntau lub zog xws li hloov hluav taws xob, kev tiv thaiv kev nyab xeeb, kev tswj ntse, kev sib txuas lus thiab lwm yam, EVSE tsis yog lub zog hloov dua siab tshiab, tab sis kev sib koom ua ke. kev tiv thaiv, kev tswj ntse, kev sib txuas lus cov ntaub ntawv thiab lwm yam haujlwm ntau. Nws muab kev nyab xeeb, ua haujlwm tau zoo thiab txawj ntse lub zog sib cuam tshuam ntawm lub tsheb hluav taws xob thiab daim phiaj hluav taws xob, thiab yog lub ntsiab lus tseem ceeb ntawm kev sib txuas lus ntse.
Raws li International Energy Agency (IEA) 2024 tsab ntawv ceeb toom, qhov kev loj hlob txhua xyoo ntawm EVSE xa mus rau Tebchaws Europe thiab Tebchaws Meskas yog ntau dua 30%, thiab kev txawj ntse thiab kev sib txuas tau dhau los ua qhov tseem ceeb hauv kev lag luam. Cov ntaub ntawv los ntawm Teb Chaws Asmeskas Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob qhia tau hais tias cov pej xeem them cov chaw nres tsheb hauv North America tau tshaj 150,000, thiab cov tebchaws nyob sab Europe tseem tab tom ua kom cov txheej txheem ntse ntse.
Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob tsheb fais fab
Tus qauv tsim ntawm EVSE ncaj qha txiav txim siab nws txoj kev nyab xeeb, kev ntseeg siab thiab kev txawj ntse qib. Cov khoom tseem ceeb muaj xws li:
1. kob
Plhaub yog EVSE "cov ntaub thaiv npog", feem ntau yog ua los ntawm cov ntaub ntawv muaj zog corrosion-resistant (xws li stainless hlau, aluminium alloy, engineering plastics), nrog rau cov dej tsis zoo, plua plav, kev cuam tshuam thiab lwm yam ntxwv. Kev tiv thaiv qib siab (xws li IP54 / IP65) ua kom cov cuab yeej ua haujlwm ruaj khov rau lub sijhawm ntev nyob rau sab nraum zoov thiab huab cua.
2. Main Board Circuit Court
Lub rooj tsav xwm tseem ceeb yog "lub paj hlwb" ntawm EVSE, lub luag haujlwm rau kev hloov hluav taws xob, kev ua haujlwm teeb liab, thiab kev them nyiaj tswj. Nws koom ua ke lub hwj chim module, ntsuas module, kev tiv thaiv kev ruaj ntseg circuits (xws li dhau-tam sim no, dhau-voltage, thiab luv-circuit tiv thaiv), thiab kev sib txuas lus module los xyuas kom meej tias cov txheej txheem them nyiaj tau zoo thiab nyab xeeb.
3. Firmware
Firmware yog "kev ua haujlwm" ntawm EVSE, uas tau muab tso rau hauv lub motherboard thiab yog lub luag haujlwm rau kev tswj xyuas cov khoom siv, kev siv cov txheej txheem them nqi, saib xyuas cov xwm txheej thiab kev hloov kho tej thaj chaw deb. Lub firmware zoo txhawb nqa ntau yam qauv thoob ntiaj teb (xws li OCPP, ISO 15118), uas pab txhawb kev nthuav dav ntawm kev ua haujlwm thiab kev txawj ntse kho dua tshiab.
4. Chaw nres nkoj thiab Cables
Chaw nres nkoj thiab cables yog "choj" ntawm EVSE, EVs thiab daim phiaj fais fab. Cov chaw nres nkoj zoo thiab cov cables yuav tsum muaj cov khoom siv hluav taws xob zoo, kub-tiv taus, hnav-tiv taus, thiab lwm yam, kom ntseeg tau tias muaj kev nyab xeeb ntawm cov dej ntws loj hauv lub sijhawm ntev. Qee qhov high-end EVSEs kuj tau nruab nrog tsis siv neeg cable retractors los txhim kho cov neeg siv kev paub thiab khoom siv lub neej.
